ABSTRACT:
A device for perforating or cutting a moving web of paper by means of pins, especially uniting paper for use in a cigarette filter attachment machine, comprises a roller carrying pins for perforating the paper in cooperation with a backing roller arranged to support the paper while it is being perforated, the backing roller being driven so that its peripheral speed equals that of the perforating roller, and having a deformable surface formed with indentations corresponding to the positions of the pins, the deformable material forming the surface of the backing roller being such that the indentations are formed by the pins when the rollers are first operated. The surface portion or portions of the backing roller aligned with the pins may comprise a thin metal portion in the form of a sleeve which covers recesses in the main body of the backing roller. The sleeve is perforated by the pins when the rollers first operate.
