Abstract
There is provided a sample warper which comprises a warper drum, a plurality of conveyor belt, conveyor belt feed means, a plurality of yarn introduction means, a plurality of yarn selection means, a plurality of shedding means, and creel means for supporting a plurality of bobbins, wherein the feed rate of the conveyor belt can be changed in accordance with the number of yarns to be warped simultaneously on the basis of preset warping conditions and warping designs. Accordingly, undulation can be prevented from occurring on a surface of wound yarns due to change in the number of the yarns to be warped simultaneously.
Claims4
A sample warper comprising:
- a warper drum;
- a plurality of conveyor belts rotatably provided on a side face of the warper drum and moving on the warper drum at a feed rate;
- conveyor belt feed means for controlling the feed rate of the conveyor belt;
- a plurality of yarn introduction means each mounted to a side surface of the warper drum for winding a yarn on the conveyor belts;
- a plurality of yarn selection means arranged in one end portion of a base supporting the warper drum;
- a plurality of shedding means provided in parallel to the longitudinal direction of the warper drum;
- creel means for supporting a plurality of bobbins, and
- means for changing the feed rate of the conveyor belt during operation of the sample warper in accordance with the number of yarns to be warped simultaneously on the basis of preset warping conditions and warping designs.
A warping method comprising the steps of:
- preparing a sample warper having a warper drum where one yarn is set to each of a plurality of yarn introduction means,
- winding a plurality of yarns on a conveyor belt moving on the warper drum at a feed rate, and
- changing the feed rate of the conveyor belt during operation in accordance with the number of yarns to be warped simultaneously.
