Abstract

521,206. Feeding webs. FORSTER, L. G., and MOLINS MACHINE CO., Ltd. Nov. 11, 1938, No. 32832. [Class 100 (i)] In a machine, e.g., a wrapping machine, in which a thin web is fed to a cutting device, cooperating shaped guide plates are provided to form a bend or corrugations extending longitudinally of the web to stiffen it, the plates acting upon a part of the web which is in tension lengthwise of the web. In one form, Figs. 1 and 3, the feed rollers 6, 7 have narrow feed flanges passing through slots 16 in a pair of guide plates 14, 15 shaped to form corrugations in the web as it is drawn, from the braked supply roll 5 to the cutting devices 8, 9. The roller 6 is mounted in a bracket 26 carried by a pivot 27. Instead of providing slots 16, two separate pairs of guide plates may be provided, one on each side of the feed rollers. Instead of corrugations, a simple transverse bow may be formed by concave and convex guide plates. Similarly shaped concave or convex knives may be employed in that case.
