Abstract
An apparatus for cutting tear-off strips from a strip of material having a width equal to the length of the tear-off strip and for applying the tear-off strip to a conveyed web of packaging material is disclosed. The apparatus has one movable and one stationary straight knife for the progressive cutting of the strip, a device to which suction can be applied for transferring the cut strip along its longitudinal axis to a suction roll, the suction roll being partially covered by the continuously conveyed packaging material. The strip is conveyed to the roll and the combination passes through a welding device for welding the tear-off strip to the web of packaging material. In order to operate at higher cycle rates, the device has a suction wheel for transferring the strip, which conveys the strip to the suction roll, the suction wheel being virtually motionless at the pick up position of the strip and being accelerated to the transfer point of the suction roll until the speeds of the suction wheel and roll are roughly the same.
