Abstract
Apparatus for depositing sheets on a stack, which permits essentially free access to the stack and can be implemented with a low outlay of materials and costs. The apparatus includes on the side of the stack (1) that faces a machine, tongues (5, 6) with which frictional elements (3, 4) can be brought into and out of contact and which can be moved in the conveying direction (10) of the sheets (2) and in the opposite direction, and can be lowered onto the stack (1), and wherein on the side of the stack (1) that faces the machine, at least one hold-down (7) is provided which can be moved in the conveying direction (10) of the sheets (2) and in the opposite direction, and can be lowered onto the stack (1).
Claims5
Apparatus for depositing sheets, conveyed in a conveying direction, on a stack, comprising:
- rotating frictional elements (3, 4), said rotating frictional elements (3, 4) being rotatable at different speeds to accommodate for sheet skew and being movable in the vertical direction (18) perpendicular to the conveying direction (10) of sheets (2) to be lowered onto the stack (1), a device for conveying sheets from a printing machine over the stack into the active range of said rotating frictional elements, on the side of the stack (1) that faces the printing machine, tongues (5, 6) with which said rotating frictional elements (3, 4) can be brought into and out of contact and which can be moved in the conveying direction (10) of sheets (2) and in the opposite direction and can be lowered onto the stack (1), and wherein on the side of the stack (1) that faces the printing machine, at least one hold-down (7) is provided which can be moved in the conveying direction (10) of sheets (2) and in the opposite direction and can be lowered onto the stack (1).
