ABSTRACT:
A labeling machine has a plurality of successive stations whereby a rotating pickup member on a revolving carrier picks up a label at one station, carries the label to a glue applicator station and transfers it to a gripping cylinder at another station. The invention provides a drum at the label supply station which rotates with the carrier and contacts the pickup member. A strip of labels passes about the drum into the nip between drum and pickup member and means, such as a steep helical thread and follower, are provided to speed up the pickup member so as to tear off the foremost label from the rest of the strip. Knives can be positioned inside the drum and cams and/or stops provided to project the knives out through slits in the drum so as to pre-score or perforate the label strip to facilitate tearing.
