Rotation stamp working with counter-rotating peg cleaner and counter plate

摘要

The rotation stamp has a drum (1) with inset stamp blades and counter plates (8) which work in conjunction with a drum-shaped peg cleaner which removes the waste material from the stamp. At least main part of the counter plates are identical and rectangular with at least three elongated parallel slots (9) in the stamp rotation direction. Outer slots are located at the same length from parallel end edges on the plates.
