Abstract
The machine comprises a dished cutter rotary supported by a shaft connected to a driving shaft by means of a sliding coupling device comprising an extension of the shaft having a radial pin sliding in slots of a hollow shaft. A grinding wheel is supported by an arm laterally hinged to the cutter and driven by an independent motor to sharpen the cutter with a constant cutting edge. The machine comprises moreover, a clutch controlling the feeding roller for material to be skived, which includes spring means providing thrust, while a speed variator makes it possible to adjust the speed of rotation of the feeding roller.
Claims8
A skiving machine for hides and similar materials comprising a dished cutter rotary supported by a horizontal shaft connected to a driving shaft by means of a coupling device capable of permitting axial movement of the shaft of the cutter, the machine comprising more over a feeding roller for material to be skived, close to the cutting edge of the cutter and a device for grinding the cutting edge of said cutter, in which the device connecting the cutter shaft to the driving shaft comprises a first hollow shaft through which one end of the cutter shaft slides, said hollow shaft having at least one longitudinal slot in which slide a pin radially protuding from the extension of the shaft of the cutter, and in which the device for grinding the cutting edge of the cutter comprises a grinding wheel operated by an independent motor and supported by an arm laterally hinged to the cutter, so that the axis of rotation of the grinding wheel moves along an arc of circle tangent to a straight line substantially at right angles to the cutting edge of the cutter.
