Abstract:
A textile winding machine is provided having an operator accommodating package readying assembly on which individual tube support members are supported at a convenient height to thereby provide an operator with ready access to the tubes or yarn packages supported on the tube support members. The textile winding machine includes a common exit path component along which tube support members are transported after unwinding of the feed packages supported thereon at the winding units of the textile winding machine and an entry conveyor device for raising the tube support members in spaced apart manner from the common exit path component with the tubes or yarn packages out of interference with one another to a feed package re-supply support assembly extending longitudinally along the textile winding machine at a height generally at the waist level of an average operator. During regular re-supply rounds, for example, an operator can conveniently transfer fresh feed packages from a rolling container or other storage device to the empty tube support members supported at waist level and the operator can manually prepare the yarn ends of any partial feed packages as well. A return conveyor allows recirculation of tube support members in a closed loop.
Abstract:
A yarn package handling assembly is provided for handling yarn packages transported on individual package support members on a textile winding machine. The yarn package handling assembly includes a yarn end disposing arrangement operable to dispose the yarn ends of yarn packages into preferred preliminary dispositions for handling at the winding stations of the machine. Another yarn end disposing arrangement is provided for more aggressively acting on yarn packages to dispose their yarn ends in a preferred preliminary disposition where the first arrangement was unsuccessful, handling yarn packages in a special manner to dispose their yarn ends in a preferred preliminary disposition and the yarn packages prepared by the more aggressive yarn end disposing arrangement are transported along a second transport path back to the path for feeding packages from the first-mentioned arrangement to the winding stations. According to one aspect of the present invention, a tube stripping device can be provided for stripping yarn from tubes. According to another aspect of the present invention, a yarn amount sensing member senses the presence of yarn on tubes discharged from the winding stations and controls recirculates those tubes having more than a minimum amount of yarn to the more aggressive yarn end disposing arrangement.

Abstract:
A method which improves the correspondence between the produced fancy yarn and the predetermined configuration of said fancy yarn. The fancy yarn is guided through a sensor device in a spinning device after it is formed and the diameter of the fancy yarn is continuously measured by the sensor device. The fancy configuration of the produced yarn is determined on the basis of the measured values of the diameter and is compared with the predetermined fancy configuration. The comparison is carried out until sufficient correspondence between the predetermined fancy configuration and the fancy configuration of the optimized, produced yarn is achieved.

Abstract:
The aim of the invention is to create a method that allows a previously produced fancy yarn to be reproduced. Said aim is achieved by a method in which a model fancy yarn is first guided through a sensor device for measuring purposes, the diameter of the model fancy yarn is continuously measured using the sensor device, the measured diameter values are evaluated, and the formation of the effect of the model fancy yarn is determined therefrom. Spinning settings are generated from the data representing the formation of the effect, and said spinning settings, which are based on the set of data, are used for producing a fancy yarn.
