摘要

The device has upper and lower molds (1) with slots having width corresponding to thickness of a support board (5) to be inserted between the molds. A free space is created between the molds and the slots for receiving a movable printed material (4) that can slide laterally on the space and is not stuck on the support board. The slots have depth sufficient for holding the board between the upper and lower molds.
