Abstract
Method and apparatus for feeding a plurality of separate slivers at a single sliver feeding station to the needles of a multi-feed high pile fabric knitting machine. The apparatus includes two or more separate assemblies of feed rolls for delivering sliver to the main cylinder of a sliver feeding device. Each assembly is provided with a separate timing control device for activating the feed rolls during selected time intervals to deliver sliver to the main cylinder to produce patterned high pile fabric. The timing control devices are operable to vary selectively the time intervals, both as to their duration and to the points in time when sliver delivery commences and ceases. The invention also contemplates a method of feeding a plurality of separate slivers at a single sliver feeding station to produce patterned knitted high pile fabrics having variable course-wise and wale-wise extending designs. Each individual sliver is fed selectively during plural time intervals of selected duration, to provide wale-wise extending, i.e. vertical designs in the fabric. The points in time when the sliver feeding time intervals commence and cease are selectively and continuously varied, to provide course-wise extending, i.e. horizontal design or patterning effects.
