Device for capturing the skein-end during the preparation of the spools to be fed to the automatic winding

摘要

Device for the preparation of the spools fed to an automatic winder comprising means for capturing and holding the thread skein-end by means of suction inside a mouth served from an individual suction system which alternatingly supplies both high and low depression suction, consisting of an individual sucking device which individually equips the preparation device with driving means at variable speed-rates for alternately generating a depression value that is high for capturing the skein-end or that is low for the release of the thread, respectively.
