Production method for beer mats with a printed facing on their visible side uses two types of sheets aligned after printing and glued to each other

摘要

Top cardboard sheets (1) are taken off a stack (A) and fed from above via a chain gripper (7) or similar to an alignment station (5) so that each cardboard sheet is deposited on a bottom cardboard sheet (2) in the right position. On the top side of the top cardboard sheets, printed images have to correspond exactly to printed images on the bottom side of the bottom cardboard sheets. An independent claim is also included for a beer mat made from compressed wood fibers.
