Automatic package changer for up to 20 yarn ends

Package changer model SE

Positions for 20 yarn ends

To secure a comprehensive quality evaluation of a yarn batch and high statistical significance of the test results, it is advisable to divide the total number of individual tests over as many packages as possible.

As a result, it is necessary to supply successive yarn ends to the testing equipment as rapidly as possible. To increase efficiencies, therefore, package change should also be automated for test instruments that have a fully automatic test sequence.

For this reason, modern automatic testing equipment for single- and twisted yarns, e.g. tensile-, twist- and yarn evenness testers, often incorporate an integrated package changer. Construction and functioning of such package changers are linked to the associated testing instruments and can only be used in conjunction with this equipment.

In addition to integrated package changers, there is also a need for autonomously operating package changers in textile testing, which can be used in conjunction with test instruments or other equipment that have no such integrated facility.

It is indeed advantageous if the changeover between packages can be carried out on the running yarn thus avoiding test stoppage, particularly for testing equipment with continuous yarn transport, like Textechno's dynamic thermal testers DYNAFIL ME or DYNAFIL C .

This equipment uses the technology developed by Textechno where the running yarn is spliced. Here, two successive splicing jets continuously interlace the two yarns that are to be joined; the yarn that has already been tested is then cut automatically. The process is suitable for all types of non- or slightly twisted continuous filament yarns, e.g. for pre-oriented yarns (POY) or textured yarns.

Usually, secure splicing of two yarn ends is possible for yarn speeds up to 500 m/min.

The Model SE package changer features 20 positions for feeding 20 yarn ends, which can be processed in the order 1 - 20 or 20 - 1.
