conveyor assemblies , which by way of an endless chain , move foodstuff packages between different processing machines are customary in e . g . the dairy industry . up to now the conveyor assembly generally was &# 34 ; tailor - made &# 34 ; for each dairy , which entails unnecessary cost and other difficulties . in accordance with the present invention a conveyor assembly of a modular design is proposed which makes it easily adaptable to differnt needs and localities . more particularly , an intermediate guideway for an endless chain is made use of as a spacer element between supporting sides of the assembly , thus providing a simple and stable construction . similarly shaped fastening devices , moreover , serve as joint pieces between different guideway sections , thus facilitating fitting - up and reducing cost .
