Patent number: 10363728Abstract: A method produces labels having multiple sheets glued together in a first surface region of the basic label and lying loosely on top of each other in a second surface region. After printing an anti-adhesion layer in first surface regions and a frame region, webs are applied and printed to produce lowermost label sheets. An anti-adhesion layer is printed onto the last web in third surface regions lying between the first and/or second surface regions and the frame region. After punching the material web between the third surface regions and the first and/or second surface regions, an outermost web is applied and printed. By punching a frame through all webs, a lattice take-off is severed, simultaneously forming an outermost sheet section in each third surface region projecting laterally beyond the lowermost label sheets.Type: GrantFiled: July 5, 2017Date of Patent: July 30, 2019Assignee: Schreiner Group GmbH & Co.
