989,681. Winding chenille. A. HERCFELDS. Sept. 29, 1961 [Oct. 5, 1960], No. 35043/61. Heading D1D. Chenille coming from a continuous chenille making machine has its tension and twist reduced during winding to values which are just sufficient to produce satisfactory winding on a bobbin or mandrel from which the thread can subsequently be removed in a coil without damaging the chenille structure. In Fig. 2 the chenille 1 coming from a pull and twist device B forming part of the chenille making device, has its twist reduced by being wound by an inverted flyer. The tension in the chenille may be reduced and regulated by driving the spindle 9 through a variable speed device which is controlled by a displaceable member about which the chenille passes. The spindle 9 is driven by at least one friction disc 15 which may have a rim of metal or be covered with leather; this friction drive may be arranged to slip when the chenille tension passes a choosen value thus acting as a tension limiting device. The spindle 9 is reciprocated by a cam 21. In other forms the flyer may be overhead mounted or, as shown in Fig. 5, the flyer and the spindle 9 are horizontally arranged. In this case the spindle has a collar 29 engaging a recess in a head 30 which is reciprocated by a cam 35 having a pair of cam grooves 33 engaged by a pair of fingers on a forked member 34. In a further form packages are slideably keyed to the spindles and rotatably rests on an horizontal platform which is vertically reciprocated by a cam to provide the building motion. In a further form a ring and traveller arrangement is provided to wind and reduce the twist in the chenille. The mandrel 13 may be elastic or be mechanically collapsible to facilitate removal of the chenille in a coil.
