Abstract: A method and apparatus for initiating feed of yarn on a machine for taking yarn from a supply, processing it and rewinding it. A short length of processed yarn is led back through a series of guide wires to a vacuum receiver for holding the free end of the yarn. The wire guides are actuated to form a large loop so that the processed yarn will be fed over the input roller and the output roller, so as to pick up yarn from the supply. The lower roller of the feed roller assembly is elongated to aid in the looping and lateral in-feeding of the processed yarn loop. The previously processed yarn, after it is fed around the input and output rollers and has picked up the additional yarn to be processed is pulled from the vacuum retaining system and incorporated in the processed yarn.

Abstract: The device according to the invention enables a false twist to be communicated to a fibrous material. The device includes two endless belts or aprons inclined with respect to each other and mounted on two pairs of rollers. According to the invention, the support rollers supporting the two aprons are mounted on the casing proper of the spindle via two support arms, one of the support arms of each pair being subjected to the action of pressure for ensuring tension of each apron and at least one of the other two support arms being mounted in articulated manner on the casing. Parallelism between the axes of the rollers is not able to be respected.

Abstract: This invention relates to a device for drawing roves or slivers of fibers on a spinning machine with a view to converting this material into spun yarns, of the type incorporating pendulous arms, constituted essentially by an assembly comprising, mounted on the support frame of the machine, a series of splined shafts extending over the whole length of the machine and common to all the work positions, said shafts being driven in rotation and, on the other hand, presser elements constituted by rollers mounted on a pivoting support arm comprising means ensuring pressure of the presser rollers against the splined shafts, wherein the pendulous arm bearing the presser elements is assembled on the frame of the machine via a support comprising means for simultaneously separating the presser rollers parallel to the line of splined shafts.
