US 4,109,357 A · Yarn severing and holding apparatus

Abstract

A yarn severing and holding apparatus for use in a system for changing spinning cans in which synthetic filamentary yarns are deposited. In this apparatus an arm supported, independently of the can transporting means, for rotation at a level between the yarn feeding device and the cans, has a slide mounted thereon for traversing movement lengthwise of the arm. This slide carries a cutting device and also a device for clamping the severed end of the yarn deposited in the full can. This insures that the cut off end of the yarn cannot drop back into the full can and that on the other hand the free end can drop into the still empty can immediately after the cutting operation. Moreover, the severing and holding apparatus is physically divorced from the can-transporting means so that the latter may be designed for either rotational or translational movement.

Dependent claims

In a spinning can changing system including a depositing device which rotates about a vertical axis, for depositing continuously fed synthetic filamentary yarn, a plurality of spinning cans and means for horizontally transporting said cans so as to move a full can away from, and an empty can into, an operative position underneath said depositing device,

a yarn severing and holding apparatus, said apparatus including:
an arm horizontally extending between said depositing device and said cans and supported for rotation, independently of the drive of said can transporting means, about a stationary vertical axis disposed outside of the range of rotational movement of the depositing device, and
a slide mounted on said arm for traversing movement lengthwise thereof, said slide carrying a severing device and also a holding device for holding the severed end of the yarn leading toward the full can.
