ABSTRACT:
A supplemental roll of label-bearing strip and a splicer for that strip are provided for a label feeder of the type which peels labels from a backing strip. A primary label-bearing backing strip is intermittently fed to a peeling edge, the label-free backing strip is pulled back to a feed roll and a rewind roll to form a narrow V space, and the splicer is located within that V space. The leading end of the supplemental roll is spliced to the tail end of the primary roll without delaying the labelling line to which the labels are supplied. An adhesive piece on the leading end of the supplemental roll normally is held within the V space in register with, but out of engagement with, the strip from the primary roll; and it is adhered to the tail end of the primary strip by a pressure device which is controlled by a photoelectric means that is located upstream of the pressure device and that responds to the passage of the tail end of that primary strip. The arrangement can be applied to existing labelling machines without modifying them, and without requiring a significant amount of additional space.
