Claims27
A package feeding method for feeding a yarn package having a first section on which a yarn layer is wound and a second section substantially devoid of the yarn layer, said method comprising the steps of wrapping an end of the yarn wound on the package in a plurality of turns about the second section of the package and transporting the package with the end of the yarn wrapped about the second section of the package.
A package feeding method in a yarn twisting machine having a large number of two-for-one twisters which are operable with two stage yarn supply packages, said method comprising the steps of:
- supporting packages of the two stage yarn supply package with a transport medium having a projected portion at a central portion of a plate-formed member and a guide pipe in the form of a pipe adapted to fit on said projected portion of said transport medium and support the packages of the two-stage yarn supply package thereon;
- and
- conveying the transport medium with a conveyor toward a two-for-one twister.
A yarn supply package feeding system in a yarn twisting machine having a large number of two-for-one twisters, said system being operable with a plurality of yarn supply packages, said system comprising:
- a conveyor arranged to convey yarn supply packages to the two-for-one twisters,
- a transport medium having a plate-shaped member and a projected portion at a central portion of the plate-shaped member said transport medium being adapted to be conveyed by said conveyor, and
- a guide pipe adapted to fit on said projected portion of said transport medium, said guide pipe being configured to support the plurality of yarn supply packages for conveyance to the two-for-one twisters.
A yarn supply package conveying system for conveying a first and a second yarn package arranged in a two-stage yarn supply package, said system comprising a transporting means for transporting the two-stage yarn supply package and a wetting means for applying a wetting agent to the first and the second yarn package in the course of transportation of the yarn supply package by said transporting means.
A package conveying device operable on a yarn supply package which is provided with a first package section having a first yarn wound thereabout and a second package section substantially devoid of the first yarn, said package conveying device comprising:
- package transfer means for transferring the yarn supply package;
- and
- yarn end finding means operatively connected with said package transfer means, for finding the yarn end of the first yarn wound about the yarn supply package transferred by said package transfer means, said yarn end finding means having yarn winding means for winding the found yarn end about the second package section of the yarn supply package.
A package transferring system for transferring a first package having a first yarn wound thereon and a second package having a second yarn wound thereon, said system comprising:
- a substantially cylindrical package support member having first and second sections configured to support the first and second packages, respectively, said package support member having a third section which is offset from the first and second packages upon the first and second packages being supported by the package support member;
- yarn end finding means operable for finding an end of the first and second yarns wound about the first and second packages, respectively, while the first and second packages are being supported by said package support member;
- yarn end winding means operable for winding the found yarn ends about said third section of said package support member;
- and
- conveying means for conveying said package support member following an operation of said yarn end winding means.
