the present invention relates generally to textile fiber processing . more specifically , it relates to the provision of an automated fiber processing system for processing textile fibers from opening through spinning in a completely automated and continuous processing sequence . the processing of textile fiber stock from opening through spinning in textile mills is a very old and well developed art . in the past , the processing sequence from bale opening to spinning has been essentially a series of individual processing steps requiring interruption of the fiber processing as the stock is transported from one individual process to another by workers . for example , a traditional interrupted processing sequence could entail the individual processing steps of opening , blending , carding , drawing , roving and spinning to produce a yarn from the bale . each sequence was labor - intensive and required the handling of fiber stock by workers and the consequential interruption of the processing of the fiber stock . with the passage of time , many new developments have come about in textile processing of fiber stock from opening through spinning which have simplified and improved the productivity of the traditional processing sequence . for example , the carding and drafting processing steps have been combined into one step by a highly efficient machine called &# 34 ; the sliver machine &# 34 ; manufactured by industrial innovators , inc . of durham , north carolina . however , even with the combination of certain historical processing steps and improved productivity realized through new and better equipment , no one to date has developed a processing system whereby textile fiber stock can be processed in a continuous , uninterrupted manner from the bale to yarn in an entirely automated system . in accordance with the present invention , applicant has discovered a new fully automated system for processing textile fiber stock in a continuous , uninterrupted sequence from bale opening to yarn . although the automated fiber processing system of the invention ca be used in conjunction with either open - end rotor spinning , ring spinning and other spinning systems , it is presently contemplated that a preferred utilization of the automated processing system would be in conjunction with automated open - end rotor spinning equipment presently known to those skilled in the textile art . therefore , it is a primary object of the present invention to provide an automated yarn processing system for processing textile fiber stock in a continuous , uninterrupted sequence from bale to yarn . another object of the present invention is to provide a fully automated fiber processing system for use in combination with conventional spinning equipment to improve yarn quality . still another object of the present invention is to provide a fully automated fiber processing system for use in combination with any of several conventional spinning apparatus . still another object of the present invention is to provide a fully automated fiber processing system for use in textile manufacturing which would significantly reduce the manufacturing cost of yarn produced thereby . it is yet another object of the present invention to provide a fully automated fiber processing system which is particularly adapted for use by textile manufacturers in plants having long continuous production requirements such as sheeting mills , denim mills and terry cloth mills in order to provide high quality yarn at a significantly reduced cost . some of the objects of the invention having been stated , other objects will become evident as the description proceeds , when taken in connection with the accompanying drawings . fig1 is a schematic view of the automated fiber processing system utilized in one of the preferred embodiments of the present invention ; fig2 is a schematic side view of a sliver - making apparatus and associated open - end spinning apparatus as used therein ; and fig3 is a schematic side view of an open - end spinning apparatus incorporating a sliver - making apparatus as an integral part of an open - end spinning machine . referring now more specifically to fig1 - 3 of the drawings , an exemplary embodiment of the automated fiber processing system of the present invention is shown . fiber stock , in the form of synthetic fiber bales and cotton fiber bales are provided to synthetic bale opener 10 and cotton bale opener 20 . although many conventional bale opening apparatus can be incorporated into the automated fiber processing system of the invention , applicant presently contemplates that the preferred equipment is readily available from many sources . from bale opener 12 , opened fiber stock is transported to step cleaner 22 and then through air conduit 24 to selected blending feeders 30 . conventional blending feeders 30 are also readily available from a number of sources . with reference now to synthetic bale opener 10 , it can be seen that the fiber selectively removed from the synthetic fiber stock bales is transported through air conduit 12 to the remaining blending feeders 30 . although a matter of design choice , blending feeders 30 are shown in fig1 as receiving cotton fiber stock and synthetic fiber stock in alternating blending feeders which is an excellent configuration to achieve good blending of a mixture of cotton fiber stock and synthetic fiber stock . blending feeders 30 blend the fiber stock and then deposit it on blending belt 32 . blending belt 32 is commercially available from a number of sources . after traversing blending belt 32 , the mixture of synthetic fiber stock and cotton fiber stock will be removed from blending belt 32 and placed into an opener and cleaner 40 which is also available from many sources known to those skilled in the fiber processing art . opener and cleaner 40 further opens the mixture of cotton and synthetic fiber stock which is then transferred to reserve hopper 50 which serves to further blend the fiber stock and provide a consistent feed thereof to the equipment downstream thereof in the automated fiber processing system of the invention . most suitably , reserve hopper 50 is a multi - cell stack blender such as is manufactured by and available from a number of textile machinery firms . next , a card chute feed system 60 is provided for receiving opened fiber stock from reserve hopper 50 and distributing it to modified carding machines 70 . card chute feed system 60 most suitably includes a fine opener 62 which initially receives fiber stock from reserve hopper 50 and further opens it prior to transfer to card chute feed system 60 for distribution to modified carding machines 70 . carding machines 70 , most suitably &# 34 ; extractor cards &# 34 ; as described in u . s . pat . no . 4 , 301 , 573 and available from industrial innovators , inc . of durham , north carolina , are all equipped with an air - doffing plenum 72 and do not require doffers , calendar sections , coilers , can changers or precision weight controls . the automated fiber processing system also obviates the need for draw frames and sliver cans . when processing cotton stock modified carding machines 70 will most suitably be set to extract about 10 - 20 % of the fibers which will be conveyed to extractor 80 by air conduit 82 . extractor 80 , described in u . s . pat . no . 4 , 301 , 573 and available from industrial innovators , inc ., will remove cotton micro - dust and short fiber for maximum cleaning , and return good fiber stock through air conduit 84 back to blending feeders 30 for reintroduction into the fiber processing system . carding machines 70 each have a production control device ( not shown ) which is known to those skilled in the art in order to control the rate of fiber stock fed to each carding machine . the process control devices serve to control the production of the carding machines in a manner which is now conventional and was developed by industrial innovators , inc . of durham , north carolina and known by the trademark smart system . next , the carded fiber stock is transported by air through distribution system 90 to a plurality of sliver - making apparatus 100 ( see also fig2 and 3 ). air distribution system 90 is most suitably a high air pressure conduit delivery system that responds , in precise amounts , to individual sliver - making apparatus 100 on demand . the total system production flow is monitored and maintained in a balanced condition based on the production requirements of the spinning apparatus as determined and regulated by tension sensors 116 and 316 , respectively , in fig2 and 3 , as will be more fully explained below . also , it should be understood and appreciated that for some processing applications a preferred utilization of the automated processing system would be to deliver the fiber directly from fine opener 62 to sliver - making apparatus 100 through air distribution system 90 and thus eliminating the necessity of processing through carding machines 70 and extractor 80 . for example , this shortened process could be used for some types of 100 % synthetics and certain cotton applications based on end product requirements . with specific reference now to fig2 it can be seen that sliver - making apparatus 100 is a small carding device which is preferably positioned where the cans are normally located in a conventional open - end rotor spinning apparatus . a sliver - making apparatus 100 can also be positioned to feed each position on a roving frame which is then linked to a ring or similar spinning system to provide a completely automated spinning system . a sliver - making apparatus 100 will be provided for each rotor of an open - end spinning frame ( or each position on a roving frame linked to a ring spinning frame ) and will be controlled by a microprocessor so as to deliver sliver at the appropriate rate as determined by the particular spinning position . in this fashion , each sliver - making apparatus 100 which will produce precision on - line weight control of sliver will also produce the correct production rate required by the spinning position . it is preferred that sliver - making apparatus 100 be constructed in a unitary frame containing multiple sliver - making apparatus 100 so as to provide the required number thereof to supply all spinning positions on a complete spinning frame . with specific reference now to both fig2 and 3 , applicant contemplates that a sliver - making apparatus 100 will be provided for each open - end rotor spinning position or each ring spinning position on one or more spinning apparatus which are used in combination with the automated fiber processing system of the invention . sliver - making apparatus 100 comprises a chute feed 102 which is fluidly connected to air transport and distribution system 90 ; feed rolls 104 that deliver fiber stock to wire licker - in roll 106 which is most suitably about 3 inches in diameter ; a carding cylinder 108 for receiving fiber stock from licker - in roll 106 and which is most suitably about 5 - 20 inches in diameter ( and preferably about 9 - 12 inches ); wire doff roll 110 for doffing fiber from main cylinder 108 ; a trumpet and drafting roll assembly 112 for forming the fiber stock into a suitable sliver which has been corrected for weight variability and adjusted to the desired grain weight required by a spinning position of a spinning apparatus ; tension sensor 116 ; and microprocessor 118 . the technology incorporated by trumpet and drafting roll assembly 112 is disclosed in u . s . pat . no . 4 , 768 , 262 issued to industrial innovators , inc . of durham , north carolina . thus , sliver - making apparatus 100 , controlled by a suitable microprocessor , will produce precision on - line weight control of fiber stock sliver required by spinning frame 200 ( see fig2 ). as noted heretofore , a sliver - making apparatus 100 will be provided for each spinning position of one or more spinning frames or roving frames linked to ring spinning frames which are fed by the automated fiber processing system of the invention . with reference to fig3 as an alternative to the stand - alone positioning of sliver - making apparatus 100 adjacent an open - end spinning or roving frame 200 in the place of conventional sliver cans , the sliver - making apparatus 100 may be integrated into the design of an open - end spinning frame such as shown in fig3 . open - end spinning frame 300 shown in fig3 would have an integral sliver - making apparatus associated with each open - end rotor spinning position which would most suitably comprise a feed line 302 which would be suitably connected to transportation and distribution conduit 90 from carding machines 70 ; chute feed 304 ; licker - in roll 306 ; carding cylinder 308 and carding plates 310 ; doffer roll 312 ; trumpet and roller drafting assembly 314 ; tension sensor 316 and sliver guide 318 . suction is provided by suction plenums 320 , and microprocessor control system 322 serves to monitor and control sliver - making apparatus 100 in order to provide the desired sliver weight and quantity to the open - end spinning rotor associated therewith . the integral sliver - making apparatus is substantially identical to the stand - alone apparatus . it should be appreciated that , most suitably , individual bale openers 10 and 20 , blending feeders 30 , opener and cleaner 40 , reserve hopper 50 , card chute feed system 60 , carding machines 70 , air transportation and distribution system 90 and sliver - making apparatus 100 all utilize microprocessor controls ( not shown ) which provide for an interactive functional relationship therebetween . a two - way communication link with a central processing unit ( cpu ) ( not shown ) is provided between each individual sliver - making apparatus 100 and carding machine 70 in order to provide complete control and management of the fiber stock by the automated fiber processing system of the invention . in operation , cotton fiber stock is removed from bales at bale opener 20 and processed through step cleaner 22 and then transferred by air conduit 24 to selected blending feeders 30 . simultaneously , synthetic fiber stock is removed from the bales at bale opener 10 and transferred by air conduit 12 to selected blending feeders 30 . the fiber stock is blended and placed onto blending belt 32 and from there transferred to opener and cleaner 40 . after being opened and cleaned , the fiber stock is next transferred to reserve hopper 50 for further blending and then through fine opener 62 to card chute system 60 to carding machines 70 . carding machines 70 are fluidly connected by air conduit 82 to waste extractor 80 which removes micro - dust and short fibers from the 10 - 20 % of fibers extracted by the carding machines and returns the good fiber through air conduit 84 to blending feeders 30 . the carded fiber stock is air - doffed by air - doffing plenums 72 and transported by air transport and distribution system 90 to a plurality of individual sliver - making apparatus 100 . sliver - making apparatus 100 are each essentially small carding units which process the carded fiber stock and form sliver as required for a corresponding open - end spinning frame position or a roving frame position linked with a ring spinning position . it will be understood that various details of the invention may be changed without departing from the scope of the invention . furthermore , the foregoing description is for the purpose of illustration only , and not for the purpose of limitation -- the invention being defined by the claims .
