ABSTRACT:
A web feed tractor includes an endless feed belt having feed pins projecting from the outer surface thereof, and a pair of side frames disposed along the opposite edges of the feed belt. A driving pulley is rotatably supported between one ends of the side frames and is adapted to engage the inner surface of the arcuate driving portion of the feed belt so as to drive the feed belt. A belt guide is provided between the side frames and has a guide surface adapted to guide the inner surface of the arcuate driven portion and the upper and lower reaches of the feed belt. The guide surface is positioned in longitudinally aligned relation to the feed pins of the feed belt and has a width substantially equal to the diameter of the feed pin.
