Abstract
A machine for providing cushioning products of varying lengths from a supply of a web material having sequential transverse rows of inflated protrusions. A pair of opposing feed members form a feed nip for moving the web along a path of travel. At least one sensor detects location information for the sequential rows of inflated protrusions as the web travels along the path of travel. A severing device is moveable between (i) an engaged position to separate the web transversely or perforate the web transversely and (ii) a disengaged position. A controller is programmed (i) to receive the location information and (ii) to operatively control the severing device to move it to the engaged position when a selected row is in a determined position relative the severing device.
