Splicer devices and winders for splicing yarns

Abstract

Splicer device (6) for splicing yarns in a winding machine wherein the yarn (2) is fed from the bottom and wound from the top on a package (12) and comprising upper (24) and lower (25) clamping members and upper (28) and lower (29) shear members, wherein the upper clamp and shears are sequentially actuated by an upper actuator (50) which firstly closes the upper clamp and then actuates the upper shears, and wherein also the lower clamp and shears are sequentially actuated by a lower actuator (51) which firstly closes the lower clamp and then actuates the lower shears, said actuators being fed in parallel by a feeding device (76) which is common to the two actuators.

Description

technical field

[0001] The invention relates to a splicer device for splicing yarns during their winding on a tube to achieve the formation of a collected package of yarns produced or processed by a textile machine. The invention also relates to a winding machine comprising such a splicer device. Background technique

[0002] In industrial practice, it is widely dominant to rotatably drive the tube (idly carried by the spindle of the package holder arm) and to withdraw the yarn from the follower to be wound on Yarn collection technology on it. The package is thus formed by pulling and winding the yarn on its surface, the package being rotatably drawn by an underlying motor-driven roller on which the package itself is supported. In this way, the yarn can be wound at a constant linear speed, independent of the dimensions acquired by the package as the winding progresses, and only as a function of the rotational speed of said drive roller.
