Abstract

An arrangement for mounting a suction tube on a fly frame, roving frame, ring spinning machine or the like for collecting broken ends of yarn at the outlet rollers of the machine. The suction tube has a suction end and an opposite end connected through a flexible sealing sleeve to a collection chamber, with the sleeve permitting the suction tube to pivot between different positions. A mounting rod is secured to and extends between the stanchions of the machine frame intermediate the collection chamber and the outlet rollers, and a support arrangement is mounted on the rod and includes a retaining mechanism for positioning the suction tube and releasably retaining it in an operative position in which the suction end is proximal the outlet rollers and an inoperative position in which the suction end is spaced from the outlet rollers. In one embodiment the suction tube is pivotally mounted on one arm of the support and releasably retained in a slot in another arm of the support. In another embodiment the suction tube is fixed to the support and the support pivots on the rod, being releasably retained in operative and inoperative positions by a ball detent mechanism or by cooperating s…
