An apparatus for processing continuous business forms stationery assemblies such as a burster, deleaver or the like. The apparatus includes a driving device for driving stationery through the apparatus along a predetermined path of stationery travel and a pair of trimming devices for trimming the longitudinal edges of the stationery. The trimming devices are mounted for independent movement and each includes an independently operable motor for moving the same relative to the sides of the path of stationery travel for adjustment purposes. Each trimming device also includes a tractor assembly and a manually operable adjustment is provided whereby the distance between the cutting knives and one of the trimming devices and the tractor assembly may be varied. Also included is a mounting for one of the knives in each trimming device whereby, when trimming is not required, one knife is moved radially and axially away from the other knife.
