LABELING APPARATUS HAVING A PIVOTABLE BASE PLATE WITH FEED WHEEL

摘要

The present invention is directed to a labeling apparatus designed to dispense and apply self-adhesive labels arranged on a carrier web, a base plate suitable therefor and a label web. A feed wheel for the carrier web is rotatably mounted on the base plate and has at both its end faces a ring of axial pins engageable by an operating lever pivotally mounted on a casing of the labeling apparatus in order to drive the feed wheel in increments. The feed wheel has a generating surface with two rings of radial projections in the form of knobs adapted to make positive engagement with recesses or cutouts of the carrier web. Instead of using knobs as projections, it is also possible to provide sprockets on the feed wheel which are adapted to make positive engagement with slits in the carrier web. The base plate is configured as an interchangeable base plate which is selectable in dependence upon the phase relationship of the rings of projections to the rings of axial pins of the feed wheel.
