Oerlikon Barmag further improves spinning process with WINGS HD

Oerlikon Barmag, which has been offering the concept for high-end home textile applications using the POY and DTY process since 2018, modified WINGS HD for increased needs and to make production simpler. The spinning concept with the WINGS HD winding unit in conjunction with an automatic eAFK Big V Multispindle texturing machine allows the manufacturing of high quality high-titer yarns with maximum machine efficiency.

Oerlikon Barmag POY Process Technology Manager Stephan Faulstich commented concerning the subject: “We have correspondingly modified WINGS HD in order to once again better align the increased requirements of these special yarns to the spinning process and make everyday production even simpler for our customers.”

Oerlikon Barmag increases parking times by up to three times in WINGS HD models

While the parking times are extremely short when winding high titers, Oerlikon Barmag has increased the parking times by up to three times in the case of the new WINGS HD models. To this end, the parking time for a 300d/384f yarn, for example, has been increased from a standard 6.5 min. to 15.7 min. – and, in the case of a 400d/192f yarn, from 4.3 min. to 10.3 min. This makes the doffing process more even, hence increasing doffing reliability.

At the same time, the draw unit now has a more flexible design, meaning that two-godet operation is also possible in the case of yarns with low overall titers. This has a positive impact on the winding unit’s energy consumption.

12 POY packages of up to 600d/576f (final) are produced in the spinning process using WINGS HD 1800. This is made possible as a result of an additional godet, which ensures that the high yarn tensions developing in the process are reduced to the yarn tensions common in the case of the winding process to date. At the same time, the newly-developed suction unit with the accompanying yarn cutting device (yarn collecting system) ensures reliable handling of the yarn with an overall titer of 7,200 den (final), both during string-up and in the event of a yarn break.

High titers can also be manufactured directly using the WINGS HD

The concept’s decisive benefit: whereas DTY yarns up to 1,200 den and with up to 784 filaments have in the past, as standard, been plied from four POY 300d/192f bobbins using DTY machines, high titers can also be manufactured directly using the WINGS HD take-up machine. And combining the WINGS HD and the eAFK Big V offers an ideal solution, as this allows all available winding positions to be utilized during texturing.
