Abstract
731,079. Feeding webs. CAMERON MACHINE CO. Sept. 2, 1952 [June 12, 1952], No. 22053/52. Class 100 (1). In a method of converting a strip of flexible web material on one roll into a plurality of various strips on another roll, the strip is slitted to form a transverse series of narrower strips, and then drawn under tension on to the other roll, successive members of said series being subjected to friction at progressively increasing angles to the line of movement of the narrower strips prior to reaching the other roll. The cylinder 20, Figs. 1 and 6. has a smooth surface and is provided with two helical feeding zones 21, 22 consisting of rubber or like material having a high coefficient of friction, or in the form of helical grooves. A web 25 is slit at 27 into sections 28, passed partly round the surface of the cylinder 20 and then to surface winding drum 31, 30 and a winding shaft 29. The surface of the cylinder 20 is caused to move at a different speed from that of the web sections 28 by means of a brake X or by means of a separate positive drive, or by using the cylinder in place of the drum 31 and allowing it to be freely rotated by the shaft 29, whereas a positive drive is applied to the drum 30. The cylinder 20 can be arranged to cause an inward instead of an outward bulge in the slitted sections. The cutter 27 may co-operate directly with the drum 30, so that the web passes between the drum and the cutter, and the sections pass round the cylinder and again over part of the drum. A top pressure roller may rest on top of the slitted sections on top of the shaft 29, and this roller may be constructed similarly to the cylinder 20.
