The picking member (212) has an outer surface section that includes a high friction portion (256) axially adjacent to a low friction portion (258). The low friction portion comprises an arcuate projecting portion that reduces risk of damage to a leading edge area of the end sheet due to opposed picking and stripping forces.

  • Publication number: 20110024972
    Abstract: A device and a method for the depositing of products, in particular print shop products that are folded and/or conveyed in an copy stream (S, S1, S2, S3), onto an outgoing conveying surface of a removal conveyor. A conveyor device with appropriate guide and conveyor elements serves for the guided conveyance of products in a substantially horizontal direction of conveyance. After leaving the exit of the conveyor device the products move, un-guided, further along a trajectory. At least one acceleration element, which is moveable along an orbital track (U) located partially above and partially below the trajectory, interacts with the un-guided products. The acceleration element gives the products an impulse in the vertical direction after the products leave the exit. By this means, a better positioning on the outgoing conveying surface can be achieved.
