Means for operating or driving plaiting winces used with dye becks or like apparatus wherein fabrics or the like are treated

摘要

PICT:0380235/IV/1 The elliptical wince for plaiting down textile fabrics or the like in rope form in dyebecks is given a uniform peripheral speed by a differential or variable speed driving mechanism interposed between a driven shaft and the shaft or support carrying the wince. A wheel j on the wince shaft j1 is geared to a smaller wheel i adapted to rotate on a fixed eccentric c on the driven shaft d. The wheel i is rotated by a pin h engaging a slot i1 in an extension from the wheel, the pin h being on a boss g keyed to the shaft d. The speed of the wheel i varies as the pin h moves up and down in the slot and the variation in speed is imparted to the wince through the wheel j.
