Apparatus for printing or applying self-adhesive labels

摘要

A hand-held labeller for printing and/or applying self-adhesive labels which adhere as a strip or separately at equal distances on a carrier strip, the apparatus comprising a frame; a supply member mounted with respect to the frame for mounting the carrier strip and labels; a label separation member mounted with respect to the frame; a feed wheel or winding drum mounted with respect to the frame; means for guiding the carrier strip from the supply member by the label separation member and then to the feed wheel; a hand lever so pivotally mounted with respect to the frame that the lever may be pivoted by an operator's hand as the labeller is being held in the hand of an operator; coupling means for coupling the hand lever to the feed wheel to operate the feed wheel each time the hand lever is pivoted and thus advance the carrier strip from the supply member so that the labels are successively separated from the carrier strip at the label separation member and the carrier strip is incrementally wound upon the feed wheel; sensing means for sensing the advancement of the carrier strip a predetermined distance; de-coupling means for de-actuating the coupling means so that the hand lever is de-coupled from the feed wheel in response to the sensing means sensing the advancement of the carrier strip the predetermined distance and thus ensure that the feed wheel advances the carrier strip the predetermined distance each time the hand lever is actuated regardless of the amount of carrier strip wound upon the feed wheel.
