Abstract

1311778 Grinding LUIGI RIZZI & C SpA 16 July 1970 [14 April 1970] 34448/70 Heading B3D A skin splitting machine comprises a device for sharpening a cutting blade 4 having two sharpening units 6, 7 disposed one on each side of the blade, each unit having a cup-shaped grinding wheel 22 which operates with a plane front surface and is vertically, horizontally and tiltably adjustable with respect to the blade. The blade runs over pulleys 2, 3, one of which is driven, and the sharpening units are arranged above and below the lower run of the belt. Units 8, 9, Fig. 2, are provided adjacent the sharpening units for advancing the blade to compensate for wear and for positioning the blade, the units being operable individual or simultaneously by a shaft 10 connected by a gear mechanism to a chain 12. Each unit 6, 7 has a fixed base 13, a slide 14 vertically displaceable by a screw 27 rotatable by a worm 24, a slide 15 horizontally displaceable by a screw (28, Fig. 3) rotatable by a hand wheel 29, and a support 16 which is rotatably adjustable in the slide 15 and carries a shaft 20 to one end of which is secured the grinding wheel 22 and to the other end is secured a pulley 21 connected by a belt 23 to a motor 17. The vertical displacement of each slide 14 may be effected by a hand wheel (25) connected to the worm 24 or by an electromagnetically operated pawl-and-ratchet mechanism which may be actuated by a timing device or a sensing device, such as a photoelectric cell or magnetic detector, to compensate for the wear of the wheels.
