Filed:

Apr 29, 1976

Appl. No.:

5/681865

Inventors:

John W. Slater - Milwaukee WI

International Classification:

B65H 2500

US Classification:

156351

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.

Inventors:

John W. Slater - Milwaukee WI

International Classification:

B65B 5106

US Classification:

531363

Abstract:

The machine of the invention comprises a pair of rolls on powered shafts with the ends of the rolls being fixed to the shafts and the central portions of the rolls floating on the shafts. When a mailing form piece and a wafer seal are moved in between the rolls, the powered roll ends engage only the form and pull it through the floating sleeves which sleeves are stopped from rotating when engaged by the seal to retard the movement of the seal and form a tight fit between the seal and the form.
