ABSTRACT:
A flying cutoff comprising a severing mechanism which is capable of displacement with the stock to be severed under the control of a linear motive power source such as fluid accelerator. A ramp-like cam member is disposed above the mechanism and, in combination with a follower roller which is connected to the upper shoe of the mechanism, drives the severing blade through the stock as the mechanism carriage travels along with the stock. At the fully extended position, means are provided to lift the cam member so as to raise the blade out of contact with the stock. CAm surfaces for linear and non-linear power transfer relationships are disclosed. The effective angle of the cam member may be adjusted to vary the power factor. A mechanism is disclosed which allows a cut to be made without linear movement of the die carriage or stock.
