Sliver feed - has path deflection above cans to the drawing units to give a short path for fine sliver material

摘要

The sliver feed to the spinning stations of a ring spinner assembly has a powdered path deflection system closely above the sliver cans to take out the sliver. The sliver path deflection system lies generally on the same horizontal plane as the powered take-in rollers of the associated drawing unit for the spinning station. The sliver cans are supported by a platform above the base level of the ring spinners. The sliver cans have a max. outer dia. of 300mm. The powered take-in rollers of the drawing units are a max. 1.4m above the base of the ring spinners. The path deflection is a feed roller, or a deflection roller with a conveyor belt round it, with a horizontal belt path as far as the powered take-in rollers of the drawing units, and passing round the take-in roller to be powered by it. The conveyor belt has a shrouding against side air, as a sliding runner The belt deflection roller is on a frame which can swing upwards, and is part of the belt tensioning system. The take-in rollers of the drawing units are as close as possible to the rear side of the ring spinners, and the drawing units are pitched at a angle of 45 deg. to the horizontal. The take-in rollers can be disengaged from a drive shaft, and their pressure rollers are loose rollers of paired pressure rollers. A funnel, in front of the take-in rollers, lifts the sliver from the conveyor belt. The conveyor belt also works with a sliver deflector. The sliver cans are placed on a conveyor belt. A conditioning channel is at each sliver can location, in a conditioning tunnel covering the sliver cans (10) between adjacent ring spinners.
