ABSTRACT:
A method of reducing trash recirculation into the fiber formation stream of an open-end spinning machine yarn formation station of an open-end spinning machine of the type having a movable trash belt which collects trash removed from sliver during yarn formation, said spinning machine having a predetermined, relatively high, conventional trash belt speed, comprising the steps of moving the trash belt at a low speed determined by the type of trash contained in the fiber, the type of yarn being spun and the type of fabric to be formed from the yarn, but in no event more than 50 percent of the conventional trash belt speed. The low speed of the trash belt is between 15 and 40 percent of conventional trash belt speed, with the low speed increasing as the proportion of heavy to light trash in the trash mixture increases. The low speed of the trash belt is varied a further plus or minus 10 percent of the conventional trash belt speed, the low speed being increased up to 10 percent for heavy yarn containing heavy trash and the low speed being decreased up to 10 percent for fine yarns containing light trash with proportional variation in the percentage of increase of decrease proportional to the range of yarn size. The low speed of the trash belt is altered when needed to accommodate changes in trash mixture content, yarn size and yarn trash content being processed on the machine. The trash is cleaned from the trash belt as the trash belt moves at the low trash belt speed.
