Abstract

1,242,904. Feed rollers. HEBERLEIN & CO. A.G. 26 Aug., 1968 [28 Aug., 1967], No. 40754/68. Heading D1D. [Also in Division F2] Yarn is forwarded between a driven roller 7 and a driving roller 3 and these rollers are (a) mounted for movement towards and away from each other, (b) arranged for relative axial movement therebetween against the action of spring means and (c) biassed towards each other with a constant pressure by a spring loaded device 17 which enables the rollers to be forced apart when a safety pressure is exceeded, e.g. when a rib of thread passes between the rollers. Further, the circumferential surface of one of the rollers has a raised peripheral rim 5 so that when the rollers are moved together so as to nip a yarn therebetween an edge of one roller first contacts the rim 5 to initiate a driving engagement between the two rollers before they have moved sufficiently together to nip the yarn. As the rollers move together, the edge of the roller moves down the sloping side of the rim 5 with relative axial movement between the rollers. As described, the driving roller with the raise rim 5 comprises a hard chromium plated steel sleeve 4 providing the working surface thereof. The driven roller 7 comprises a plastics coated metal ring 46 which is mounted on bearings on an eccentric boss. The boss is rotated by handle 6 to move the rollers 3 and 7 towards and away from each other. The spring loaded device 17 comprises a hollow cylindrical housing 19 having a spring seating (20) which is axially slidable and lockable in a position by screws (21). The seating (20) has a partition (25) with two springs (26, 27) one at each side of the partition. Spring (26) provides the constant pressure between the rollers.
