SINGLE-HEAD OR MULTI-HEAD EMBROIDERY MACHINE HAVING A TWO-THREAD LOCKSTITCH ROTARY LOOPER
The invention relates to a single-head or multi-head embroidery machine including stitch-forming tools which are each formed by a thread-guiding needle interacting with a two-thread lockstitch looper for forming stitches, and also including a feeding device for achieving relative movements between the material to be embroidered and the stitch-forming tools, which take place as a function of the movements of the needle. In order to avoid a temporal overlap of the stitch-forming phase with the feeding movement of the material to be embroidered the two-thread lockstitch looper rotates at a speed which corresponds to <n times> the speed of the main shaft of the machine, where <"n" is a whole number which is greater than the number "2">.
