US 2025/0051970 A1 · METHOD AND INSTALLATION FOR PRODUCING A TWISTED SYNTHETIC YARN

Abstract

A method and an installation for producing a twisted synthetic yarn, comprising a spin-drawing installation configured to produce continuous filaments from a liquid plastics material or granular material by at least one spinneret and then to produce at least one yarn from at least two continuous filaments. A downstream treatment apparatus treats the at least one yarn which is transferred, without interruption, from the treatment apparatus to a downstream twisting/cabling apparatus via a collection and transport apparatus in a continuous process from the spin-drawing installation to the twisting/cabling apparatus. The collection and transport apparatus is configured to compensate for a difference in a production speed between the spin-drawing installation and the twisting/cabling apparatus.

Dependent claims

A method for producing a twisted or cabled synthetic yarn, comprising the steps of:

producing with at least one spinneret in a spin-drawing installation continuous filaments from a liquid plastics material or granular material and then producing at least one yarn from at least two continuous filaments;
inputting the at least one yarn into a treatment apparatus;
transferring the yarn from the treatment apparatus, without interruption, to a twisting/cabling apparatus, via a collection and transport apparatus;
and
buffering a predetermined length of the at least one yarn in the collection and transport apparatus in order to compensate for a production difference between the spin-drawing installation and the twisting/cabling apparatus.
