Abstract
256,422. Humpage, T. Sept. 28, 1925. Band apparatus; machine cutters, grinding in situ.-The rotating circular knife of a cigarette making or like machine, which knife is reciprocated in a direction transverse to the cutting direction, is sharpened by contacting at the ends of the strokes with the abrasive surface of an emery &c. strip which is wound slowly from one reel on to another. The strip passes from a reel 31 over pulleys 32, 2, 33 on to another reel 34, the knife 22 lying between the runs of the strip. The strip is wound on to the reel 34 by means of a rubber belt 37 driven by a pulley 35 and passing over a pulley 36 on the end of a pivoted arm 38, the weight of the parts holding the belt in contact with the strip. In order to ensure tight winding, the reel is driven by a belt 40 from a pulley 39 driven by frictional contact with the pulley 35, slip occurring when the speed of winding is less than that which the belt 40 would produce. When the strip is entirely wound on to reel 34, the.belt 37 is thrown over to reel 31 and the belt 40 also is transferred thereto, the strip being wound on to reel 31. The strip is adjustable with respect to the knife edge by means carried on columns 14, 15 supporting the reels &c. The pulley 41 may drive the reel frictionally instead of the pulley 39 being driven frictionally. Specification 256,370 is referred to.
