ABSTRACT:
A compact labeling machine for applying pressure sensitive labels to mailing pieces such as magazines and envelopes is provided with a variable speed drive and is adapted to accommodate various size labels and mailing pieces at a high output rate. Positive control of an article feed roller associated with a supply hopper is afforded by a microswitch which is actuated by flights or lugs on conveyor chains which carry the article to be labeled from the feed roller to the labeling station. The article feed cycle is stoppd by a microswitch which has a feeler engaged by articles carried by the conveyor flights. The label feed mechanism includes a brake and clutch connected to a draw roller which draws the label web over a peel plate for positive control of the label feed. The label feed cycle is commenced by engagement of the article to be labeled with the feeler of a switch in the conveying path. A light sensor associated with the label carrying web monitors the presence of a label and the gap between labels and de-energizes the label drive feed clutch when a gap between labels is sensed. The label web stops when a label is partially peeled from the web. The article sensing switches are adjustably mounted for longitudinal movement so that adjustment of switch position is easily accomplished for appropriate timing of the article and label feed cycles for articles of different sizes.
