Problems solved by technology

[0004] The clamping device has the following disadvantages: Even with the shoulders, thread ends can penetrate the annular chamber
Consequently, the clamping effect that can be exerted on the yarn is reduced with increasing contamination of the annular groove, which further impairs the function of the clamping device

Embodiment Construction

[0022] figure 1 The spindle top 1 of a textile machine spindle, in particular a spinning spindle and a twisting spindle, is shown. The spindle upper part 1 has a shaft made of metal for receiving a tube, not shown, onto which the yarn is to be wound into a bobbin. For this purpose, a spinning ring, not shown, is arranged on the spindle upper part 1, which surrounds the spindle upper part 1 concentrically, and on which the traveler turns, deflecting the yarn onto the tube so that the Yarn is wound on it. A drive spindle 2 is arranged on the spindle upper part 1 by which the spindle upper part 1 can be driven during operation of the spinning machine.

[0023] The drive spindle 2 has a yarn 3 for fastening a clamping device 4 according to the invention for clamping the yarn during doffing of a finished bobbin. The clamping device 4 is actuated by centrifugal force and can assume two positions - a clamping position in which the yarn is clamped and an open position in which the ...

Abstract

The present invention relates to a clamping device (4) for clamping threads on a spindle of a spinning or twisting machine, the clamping device (4) being arranged on a top spindle part (1) and comprising a fixed clamping element (5) and an axially displaceable clamping element (6) which can be pressed by a spring force against the fixed clamping element (5), wherein centrifugal-force elements (9) can bias the displaceable clamping element (6) counter to the spring force by means of a force which spaces the displaceable clamping element (6) apart from the fixed clamping element (5) in the axial direction such that a clamping nip (16) forms between these elements and wherein the clamping device (4) has holders which serve for accommodating and guiding the centrifugal-force elements (9), the holders for the centrifugal-force elements (9) being arranged on that side of the clamping device (4) which is located opposite the clamping nip (16), and a compression spring (8) being arranged between the holders and the clamping nip (16).

Description

technical field [0001] The invention relates to a clamping device according to the preamble of claim 1 for yarns on spindles of spinning and twisting machines. Background technique [0002] DE 196 28 826 A1 discloses a clamping device having a clamping element rigidly attached to a spindle carousel and a clamping element axially movable relative to the longitudinal axis of the spindle. The movable clamping elements and the spindle disk are pressed against each other by compression springs mounted on the movable clamping elements, so that a clamping gap is formed between the clamping elements. In order to open the clamping gap by moving the movable clamping element against the compression spring force, the movable clamping element has an inwardly inclined conical annulus which, together with the fixed clamping element, delimits an annular chamber which can be The moving centrifugal force element is arranged in the annular chamber. When the critical rotational speed is excee...
