Abstract: A method produces labels having multiple sheets adhesively interconnected in a first surface area region of the basic label and lying loosely on top of each other in a second surface area region. After imprinting a carrier web, including imprinting an anti-adhesion layer in first surface area regions and a frame region, material webs are applied and imprinted to produce lowermost label sheets. An anti-adhesion layer is imprinted onto the last material web in third surface area regions lying between the first and/or second surface area regions and the frame region. After punching the material web between the third surface area regions and the first and/or second surface area regions, an outermost material web is applied and imprinted. By: punching a frame through all material webs, a waste matrix is severed, simultaneously forming an outermost sheet section in each third surface area region projecting laterally beyond the lowermost label sheets.
