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.
In a hand-held labeller for printing and/or applying self-adhesive labels, which adhere as a strip or separately at equal spacings on a carrier strip which is formed with recesses or marginal indentations which are arranged at spacings which correspond to the spacings of the leading edges of the labels, equipped with a feed mechanism which pulls the carrier strip intermittently for the feeding of a label and a feeler device for feeling the label carrier strip, said feeler device including projections for engaging the recesses or marginal indentations of the carrier strip to sense advancement of the labels a predetermined distance to a printing and/or dispensing position which is to be exactly assumed, the improvement where the feed mechanism comprises a winding drum for winding up the carrier strip, the drum including a non-reverse stop, and means for driving said drum including a freewheel clutch controlled by the feeler device through such an angle of rotation that the section of the carrier strip wound on the winding drum always corresponds to the predetermined distance regardless of the amount of carrier strip wound on the winding drum.
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, said apparatus comprising
