PREVENTION OF LABEL ROLL TELESCOPING AND MUSHROOMING IN A HAND HELD LABELLER

摘要

Docket M-411 HAND-HELD LABELER There is disclosed a hand-held apparatus for applying pressure sensitive labels releasably secured to a web of supporting material. The web and labels which it carries are arranged in a roll. The apparatus includes a housing which rotatably mounts the label roll. The housing has a handle. The housing also mounts a delaminator at which labels are delaminated from the web. An actuator disposed at the handle is coupled to a driver. Actuation of the actuator advances the web to delaminate labels. A curved leaf spring mounted to the housing extends partially about the label roll. A pair of fingers cantilevered to the leaf spring straddle the label roll to obviate excessive telescoping of the label roll. The leaf spring preferably extends in close proximity to the outer surface of a full label roll to prevent excessive unwinding of the roll. In addition the leaf spring effects gradual paying out of the web from the label roll.
