Abstract:
An apparatus for driving interweaving threads in a yarn-forming unit of a chenille machine, the apparatus comprising:a gauge with fuzzy thread wound thereon;a circular blade for cutting the fuzzy thread into lengths of predetermined extension, said circular blade being located in front of said gauge;an upper roller disposed at a short and preset distance from said gauge;a lower roller disposed at a short and preset distance from said gauge, said upper roller and said lower roller cooperating to form a calender which drives into motion two threads to be twisted in order to engage lengths of fuzzy thread, the axis of rotation of said pair of rollers being parallel and being parallel to a plane of said circular blade whereby the periphery of said rollers is orthogonal to said gauge, said upper roller having a plurality of radial channels;an air-suction device to apply suction to said upper roller in communication with some of said radial channels, over an arc region corresponding to radial channels in an arc region of said periphery of said upper roller, which faces the gauge during the rotation of the rollers, whereby said suction pulls in the lengths of fuzzy threads being cut by the blade towards said arc region of said periphery to be engaged by the two threads.
