Abstract
A method for winding a fixed length of yarn on a yarn-supply package in an apparatus connecting an automatic winder or an innovation spinning machine having a winder with a two-for-one twister. The method comprises dividing a single yarn-supply package transferred from a winder side to form a plurality of twist-yarn packages on the two-for-one twister side.
Claims9
A fixed length winding method in a two-for-one twister, the method comprising winding a yarn having a fixed length by a winder to form a package, once cutting a yarn and thereafter further winding the same amount of yarn on said package to form a maximum yarn-supply package capable of being mounted on the two-for-one twister, and mounting said yarn-supply package on said two-for-one twister to produce a plurality of twist-yarn packages having a fixed length of yarn from a single yarn-supply package.
A method for winding a plurality of fixed length yarn segments on a package using an automatic winder or a spinning machine having a winder, wherein said package forms the supply for a two-for-one twister, said method comprising dividing a single yarn-supply package transferred from a winder side to form a plurality of twist-yarn packages on the two-for-one twister side, characterized in that in winding on the winder side, a wound yarn is once dropped out of yarn layer or cut every time a fixed length of a length corresponding to a twist-yarn package is obtained, and thereafter steady-state winding continuously takes place to obtain a single yarn-supply package, and in winding on the two-for-one twister side, doffing is effected when twisting is discontinued due to said drop-out or cutting to form a single yarn-supply package into two or more twist-yarn packages.
An apparatus for winding fixed length of yarn in which a yarn-supply package exchange device is arranged between an automatic winder or a spinning machine having a winder and a two-for-one twister, and these are connected, characterized in that on a doffing truck which is provided on the side of a winder, is movable along each winding unit and is provided with a roller, a yarn guide, a lever for removing a full package, an empty bobbin mounting arm and a cutter, are provided a full package detection sensor and a detachable stopper actuated by the full package detection sensor to release at least the empty bobbin mounting arm and the full package removing lever, and a winding diameter detector is provided on a winding portion on the side of the two-for-one twister.
