Abstract The disclosure concerns a label peeling device for use with a label issuing machine, such as a hand labeler or a measuring printer. There is a feed unit for feeding a label web, which web comprises a plurality of labels temporarily adhered in series to a web of backing paper. A peeling unit turns and deflects the backing paper web rearwardly, as it is being fed by the feed unit, and the labels peel one by one from the backing paper at the line of deflection due to the rigidity of the labels. An auxiliary label peeling member is arranged in the vicinity of that portion of the peeling unit at which the backing paper and the labels separate. In some embodiments, the auxiliary peeling member has a label abutment portion so placed, shaped and sized that any label which might fail to peel from the backing paper merely by the reverse turning of the backing paper web is moved to abut the label abutment portion until it is forcibly peeled from the backing paper. The auxiliary peeling member comprises a rotary member which is rotatable in the advancing direction of the labels. Any label, which might otherwise fail to peel off, abuts and rides over the rotary member. In another embodiment, a scraper reciprocates toward the deflection line along the surface of the backing paper from which the labels are peeled for peeling any label off the backing paper web.
A label issuing machine, comprising: a machine body; a supply unit attached to the body for supplying a label web, wherein the label web comprises a plurality of labels adhered in series to a web of backing paper; a label peeling device for peeling each label, in turn, from the web of backing paper; the label peeling device comprising: a peeling unit past which the label web is advanced, and the peeling unit including deflecting means for deflecting the backing paper web sharply in a direction that labels will normally separate from the backing paper web as the backing paper web advances past the deflecting means; a feed unit for feeding the label web from the supply unit, for advancing the label web past the deflecting means, and for advancing the backing paper web beyond the deflecting means; an auxiliary peeling member in the vicinity of the deflecting means for completing the peeling of labels which have begun to peel from the backing paper web at the lead edge of the label; the auxiliary peeling member being reciprocated from a position along the backing paper web which is spaced from the deflecting means along the part of the backing paper web after the labels have been peeled and being reciprocable toward the deflecting means and over the surface of the backing paper web from which the labels are being peeled, the peeling element being movable for engaging the leading end of any label part of which has remained adhered to the backing paper web past the deflecting means and for peeling that leading end and the label from the web of backing paper.
