Process and compression-folding machine for the folding and simultaneous adhesive bonding of form letters

摘要

The form letter (10) is subdivided into two letter parts (16, 18) by the folding line (14). As seen in the direction of the arrow (Z), the leading letter part (16) has re-moistenable adhesive (22) in the portion (20). The letter part (18) is likewise provided with re-moistenable adhesive (22') in the edge portions (30). When the leading letter part (16) is being introduced into the folding pocket (40) of a compression-folding machine, the adhesive (22) is wetted by a moistening device. The adhesive (22') is likewise moistened by the wetting elements (42). During the subsequent folding along the folding line (14), the two letter parts (16, 18) come into overlap with one another and are adhesively bonded along the side edges (12) and along the end region of the overlap located opposite the folding line (14). <IMAGE>
