Embodiment Construction

[0037] Figure 1 shows parts of a device for preparing yarn ends for subsequent joining of yarn ends to fiber material, for example in the rotor of an air spinning machine, or for joining yarn ends to another during splicing yarn head. The device has a yarn end preparation device (GEP) 1 comprising a cavity open at least towards one side, into which the yarn end is introduced via an inlet 2 after being cut to length by a cutting device 3 Inside. Here, a mechanism is assigned to the GEP1 or the yarn end, by means of which the yarn end and / or the GEP1 can be moved substantially in the axial direction of the thread introduction at least during the preparation of the yarn end.

[0038] In the embodiment shown in FIG. 1, the mechanism is a pair of feed rollers 4 provided with at least one, in particular reversible, individual drive. For example, the yarn end of the yarn 7 wound on the cross-wound bobbin is usually moved to the vicinity of the GEP1 by the grabbing device 5 after th...

Abstract

The invention relates to a textile machine having a yarn end preparing apparatus and a method for preparing the yarn ends cut according to fixed length on the textile machine. The yarn ends can be combined to the fiber material subsequently. Wherein, the yarn ends is introduced into the yarn end preparing apparatus and then at least one stream is introduced for the preparation. In the process for preparing the yarn ends, a relative movement along the axial direction of the yarn en, is operated between the yarn and the yarn end, which is used to loose the existing abdominal belt and ensure a fast and reliable preparation of the yarn ends.

Description

technical field [0001] The invention relates to a method for preparing a cut-to-length end of yarn on a textile machine, in particular an air spinning machine, for subsequent joining of the end of the yarn to a fiber material, wherein the end of the yarn is introduced into the yarn In the lint preparation device (hereinafter referred to as GEP), and then by at least one air flow for preparation. The invention also relates to a textile machine, in particular an air spinning machine, comprising a GEP for preparing a cut-to-length yarn end for subsequent attachment of the yarn end to a fiber material, wherein the GEP There is a cavity open to at least one side, into which the yarn end is introduced. Background technique [0002] In order to be able to reattach the end of the yarn to the fiber material of the spinning device after a thread break during spinning or winding and rewinding of the yarn on the textile machine, or to attach the end of the yarn to another thread during...
