ABSTRACT:
A method and apparatus is disclosed for heat-setting carpet yarn by conveying continuously running yarn through a heat-setting chamber. To facilitate production of variable texture yarn, a controllable oscillating yarn supply tube assembly is provided for laying down various yarn patterns on a conveyor belt which travels through the heat-setting chamber. The oscillating yarn supply tube assembly is configured to facilitate switch of production between straight-set and various highly crimped textured yarn patterns via simple adjustment of the drive motor which oscillates the yarn supply tube. The apparatus can be used for a new machine as well as for conversion kits for existing carpet heat-setting machines having stuffer boxes supplying highly crimped yarn to a conveyor belt.
