ABSTRACT:
A tractor feeder for feeding continuous printing paper having perforations along its side fringes by driving pins engaged to the perforations. The pins are formed on the outer surface of an endless belt which is passed around a drive sprocket on one hand and a guide member on the other hand. The guide member is adjustable by an adjusting member such as an eccentric cam so as to apply a desired tension to the endless belt. The guide member may be provided with a roller rotatively supported by the guide member or a pair of rollers rotatively supported by the frame so as to minimize the friction to the traveling motion of the endless belt. These pulleys may be provided with flanges so that friction between the side edges of the endless belt and the guide member may be minimized.
