Abstract

761,174. Grinding paper. DORR-OLIVER Inc. June 18, 1954, No. 17935/54. Class 60 [Also in Group VIII] Webs of paper 7a, 4a, Fig. 13, are ground along their edges and adhered with a lap joint. The grinding-wheel 73, Figs. 1A and 8, rotates with the feed of the paper, e.g. at 30 times its speed. The paper is drawn. over a rod 163 received in a slot 176 of a bar 162 clamped in a groove in a table top 71 by turning a grooved rod 164, cam-surface of which co-act with pins 169. The rod 163 may be such that dust does not tend to collect thereon, e.g. of chromium plated metal, hard glass, or diamond, an exhaust pipe 179 removing dust. The grinding-wheel 73 is supported on beams 74 &c. pivoted at 77 and pressed by spring action at 96 &c. against set-screws 84 which contact accurately-machined faces 83 of legs of the beams 74. A dresser-wheel may be secured to the beams 74 when needed for dressing the grinding-wheel 73. The wheel 73, which may be of resin-bonded fine-grain grit, may be raised from the paper by an eccentric mounting 108 &c.
