Double sided transporting device has guiding gearwheel as center piece, output gearwheel with more teeth for movement against direction of rotation, and output gearwheel with fewer teeth for movement in direction of rotation

摘要

The double sided transporting device has a capability for a movement in and against the direction of the rotation, and a capability for a movement by a speed difference. The device comprises a guiding gearwheel (Z20) as a center piece, an output gearwheel (Z19) with more teeth for the movement against the direction of rotation, an output gearwheel (Z21) with fewer teeth for the movement in the direction of rotation, forming a transporting construction which through the difference in the number of teeth creates a movement at different speeds in and against the direction of rotation.
