Abstract
736,957. Drafting roller arrangements. RAPER, G. F. Oct. 27, 1952 [Oct. 27, 1951], No. 25175/51. Classes 120(1) and 120(2). Heavily loaded front drafting rollers which confine a sliver to less than its free width comprise two or more co-operating rollers in one or more of which a peripheral groove is formed to receive the other roller or rollers. In one form, a narrow roller b rotates in a groove a<SP>1</SP> in a driven roller a against which it is pressed by a spring i held in a frame k pivoted at e and exerting pressure on a bridge member d<SP>1</SP>. Side cheeks r depending from the bridge member d<SP>1</SP> guide the sliver into the groove a<SP>1</SP>. Scrapers or felt pads s and t are provided to keep the rollers a and b free from loose fibres. In other modifications, two rollers rotate in the groove of a bottom roller, or two grooved upper rollers rotate on a narrow bottom roller. The fibre contacting surfaces of the rollers may be concave, or the rollers may be mounted on their shafts to permit lateral tilting, or the rollers may be mounted on a bush of resilient material.
