Abstract: For variation of the lateral positions of pairs of paper tractors, each tractor is slidable on a separate rack which is itself axially slidable. Coarse adjustment is according to preset positions of the tractors on the racks. Fine adjustment is by driving both racks of a pair of tractors together or driving only one of those racks.

Abstract: Web feeding apparatus comprising two pairs of web drive tractors, each pair drivable from a different one of two shafts, and an endless flexible belt by which the shafts are driven, the belt having a generally T-shape to engage the shafts at ends of the T-head and a drive wheel in the base of the T with a pair of idlers on either side of the T-stem and head junctions, in which the pair of idlers are moveable together in a curve transversely of the T-stem in the plane of the T. Such arcuate movement of the idlers with the drive wheel locked causes rephasing of the drive shafts and thus of the driven web.
