Systems for collecting and recycling winding waste

Abstract

Device for collecting the scraps produced by a spooler both for "dust removal" and for the pieces of yarn, wherein the spooling units are served by single aspirators that individually equip each spooling unit, and are each equipped with a separating filter for the dust and for the pieces of yarn, which collects both materials. All of the filters are connected through a common duct to a common suctioning filter for collecting the spooling scraps that, periodically treating an individual filter at a time, discharges and receives without selection the material retained by such individual filters.

Description

Technical field [0001] The present invention relates to a device for collecting and recovering waste materials generated during a winding process through a unit constituting an automatic winder. Background technique [0002] In industrial practice, a technique of producing yarn in a spinning stage followed by a winding stage is usually used. In the winding stage, the yarn is unwound from its spool, cleaned of its defects, and then rewinded onto a reel. The winder actually includes a number of winder units, which are arranged along the front of the machine and are provided with common control and service equipment. In these shared service facilities, a device for preparing a spool to be unwound in the winding unit is provided. [0003] As already described in the previous Italian patent application IT 2009A2013 in the name of the same applicant, the configuration of the winding unit is figure 1 Shows its basic components in figure 1 The path of the yarn 2 from the lower spool 1 to ...
