Abstract
Apparatus for severing the running web of tipping paper in a filter tipping machine has a rotary drum-shaped counterknife which cooperates with equidistant knives at the periphery of a rotary knife carrier to sever the leader of the running web at regular intervals. The knives are individually adjustable with reference to the counterknife so that their cutting edges merely contact the peripheral surface of the counterknife when they assume severing positions in planes including the axis of rotation of the counterknife, and each knife is unyieldingly held against any movement relative to the carrier when the apparatus is in actual use so that the adjusting mechanisms for the knives need not take up any of the stresses which develop when the knives cooperate with the counterknife to sever the running web.
