Problems solved by technology

In each case the end of the thread is located outside the opening of the opening tube and the suction thus requires the thread to form a loop (even if only a small one) for the suction process, which may result in a yarn with a specific bending stiffness Can't really be reliably inhaled even with this method

Embodiment Construction

[0054] figure 1 A side view of a textile machine for the production of cross-wound bobbins, designated as a whole with reference numeral 1 , is schematically shown, which in the embodiment is an automatic cross-winder.

[0055] As is known, an automatic cross-winder 1 of this type has, between its end frames (not shown), a plurality of homogeneous stations, in this application winding heads 2 . On this winder 2, a spinning package 9, preferably produced on a ring spinning machine (not shown), is wound into a large-volume cross-wound package 15, which is Once produced, it is delivered to a cross-wound bobbin conveyor 21 along the length of the machine by an automatically operating service unit (also not shown).

[0056] Such an automatic cross-winder 1 usually also has a logistics device in the form of a bobbin and bobbin transport system 3 . Spinning bobbins 9 or empty tubes 9' positioned vertically on the transport disc 8 circulate in the bobbin and bobbin transport system ...

Abstract

The present invention relates to a method, device and computer program for thread opening of a splicer, the method comprising the steps of: (i) cutting the thread by a cutting device of the splicer, wherein the thread is located in the holding and In the feeding area of ​​the opening tube; (ii) at the latest after cutting the thread, apply a suction flow to the holding and opening tube; (iii) suck the thread ends by means of the suction flow applied on the holding and opening tube into the holding and opening tube; (iv) opening the thread ends by means of an opening flow applied to the holding and opening tube at the latest at this moment. The following steps are inserted between steps (ii) and (iii): (ii.A) conveying the thread end into the feeding area of ​​the holding and opening tube by the combined action of the suction flow and the thread pull-back device. Furthermore, the invention relates to a device for carrying out the method and a computer program loaded on a program control device for carrying out the method.

Description

technical field [0001] The invention relates to a method and a device for thread opening of a splicer, as well as a computer program for controlling such a method. Background technique [0002] Such a thread opening device used in conjunction with a splicer has been known for a long time, for example through DE4420979A1. Here, a splicer refers to a device used to connect two thread ends, and here and below, a "thread" shall refer to a structure composed of a plurality of individual fibers spliced ​​together with each other. [0003] Before the actual connection, the thread ends must first be prepared for this. That is to say, the thread is first cut in a defined manner by the cutting device of the splicer, after which the thread twist at the end of the thread is loosened by twisting over a certain length. It is done by twisting the pneumatic opening wire in the specific opening tube. For this purpose, after being cut, the thread ends are first sucked into the tube by a su...
