Abstract: A web feeding, cutting and dispensing machine includes a pneumatic cylinder for moving a hot wire to cut measured-length sheets from web stock. A pneumatic clamp cylinder moves a clamp bar for momentarily clamping the web during cutting. Upon pressing a start button, a pneumatic control valve sequentially operates the respective cutting and clamping cylinders for quickly retracting the hot wire, while more slowly retracting the clamp. Conversely, after the next measured web length has advanced, this control valve again sequentially operates these two cylinders in reverse order for quickly clamping while slower cutting. This dual control by one valve is advantageously achieved (1) by throttling air flow in retracting the clamp cylinder relative to retracting the cut cylinder, and conversely (2) by throttling air flow in advancing the cut cylinder relative to advancing the clamp cylinder.

Abstract: There is disclosed web feeding apparatus and method for feeding a web from a web roll to a utilization device. The paying out of the web from the web roll into a U-shaped buffer loop is assisted by a pair of cooperating feed rolls which engage the web along the buffer loop.
