Abstract:
Appliance for manufacturing a strip with self-adhesive labels or other materials with parts placed underneath, in particular a label strip on which removable, self-adhesive labels are applied to a carrier strip, on which carrier strip other parts are provided under the actual label, which other parts, when the self-adhesive label is detached from the carrier strip, can be transferred together with the latter onto an object to be furnished with the label, the appliance comprisinga first supply spool (10), with associated transport device, from which a first carrier strip (11) with labels (12) is unrolled, a first removal station (13) at which the labels (12) from this first carrier strip (11) are released and, after forward transport over a region which is free from carrier strip, are deposited on a second carrier strip (14), a first winding spool (15), with associated transport device, on which the first carrier strip (11) is wound, a second supply spool (20), with associated transport device, from which is unrolled a third carrier strip (21) with other parts (22), which are applied to it and which have to be arranged under the label (12), a second removal station (23) at which the other parts (22) are released from this third carrier strip (21) and, after forward transport over a region which is free from carrier strip, are deposited on a fourth carrier strip (24), a second winding spool (25), with associated transport device, on which the third carrier strip (21) is wound, a controlled intermittent drive for the third carrier strip (21), with the other parts (22) on it, by means of which this third carrier strip is guided locally, fed forward in a controlled manner and intermittently driven in such a way that the other parts (22) can be deposited on the fourth carrier strip (24) at desired position, the controlled intermittent drive including holding and drive rollers (29) for intermittent forward feed of the third carrier strip (21) with the other parts (22) on it, and a quick-action clutch operatively connected to the holding and drive rollers so as to connect and disconnect the holding and drive rollers from a drive motor, a third winding spool (15), with associated transport device, on which the second carrier strip (14) can be wound, the winding speed corresponding approximately to the unwinding speed with which the first carrier strip (11) is unwound from the first supply spool (10), wherein the fourth carrier strip (24) furnished with the deposited other parts (22) comprises the second carrier strip (14) on which the labels (12) released at the first removal station are deposited accurately with respect to location and time at the desired position and, by this means, cover the other parts (22) at least partially.
