Singling device for removing sheets of paper from stack uses rollers moving over top sheet in stack to slip sheet off stack in opposite direction to separation direction

摘要

Rollers moving over the top sheet in a stack of sheets are used in a singling device for removing sheets of paper from the stack. They can make the top sheet curl and can slip it off the stack in the opposite direction to the direction of separation. The distance between the stack of sheets and the separation device may depend on the quality of the paper, air temperature and relative humidity etc.
