Abstract

The invention relates to a device for producing a strip with self-adhesive labels (12) or other materials with parts (22) placed underneath. According to the invention, the labels are detached from a first carrier strip (11) at a first removal station (13) and placed onto a second carrier strip (14). The other parts (22) are delivered intermittently on a third carrier strip (21). A second removal station (23) detaches said other parts and placed them on a fourth carrier strip (24) in the desired position. Said fourth carrier strip may act as the second carrier strip (14). The original carrier strip (11) may also act as the second or fourth carrier strip. The other parts (22) can be placed in any position under the labels (12) using an appropriate control system.
