Abstract
A tractor for a web feeding assembly has a chassis providing a pair of apertures extending therethrough and a belt extending thereabout. A drive pulley mounted in one of the chassis apertures is engaged with the driven surface of the belt and has an aperture therethrough receiving the drive shaft. Convexly arcuate belt support means cooperates with the drive pulley to define the web drive path for the belt therebetween, and a cover on the chassis overlies the belt and web drive path. Belt tensioning means is movably supported on the chassis below the drive path for resiliently biasing the belt against the guide means. As a result, pressures on the belt during operation of the tractor tending to produce deflection away from the cover are resisted by the belt tensioning means to maintain a rectilinear drive path for the web tightly against the cover.
