Continuous business forms are detached and disposed in offset stacks. Continuous forms being fed into a conventional detacher are sensed by a first optical sensor, and after detachment are conveyed by a roller conveyor away from the detacher in a first direction. A guide rail is elongated in generally the first direction and the detached forms have an edge which engages the guide rail so that all the forms in a particular group are aligned when discharged from the conveyor into a stack. The guide rail is mounted on guide rods, for movement in opposite second and third directions, both generally perpendicular to the first direction, so as to change the position of the edge of detached forms in a subsequent group of forms so that consecutive stacks are offset from each other. A second optical sensor at the discharge of the conveyor cooperates with the first sensor and a control mechanism to operate the detacher and solenoids for moving the guide rail between its different guiding positions to form offset stacks of business forms.
