A direction of movement of substantially fiat elements, such as sheets or business forms, is changed about 90 DEG , without rotation of the forms. Nip rolls receive the forms driven in a first direction and accelerate the forms to make them airborne until they hit an adjustable abutment on the opposite side of an endless belt conveyor from the nip rolls. The endless belt conveyor conveys the forms in a second horizontal direction substantially perpendicular to the first direction. The forms may be shingled when moved both in the first and second directions, or can be deshingled by controlling the aspect ratio of the forms, the ratio of speeds of the elements, and the degree of shingling.
