Clog preventive device for label printing and applying machine

摘要

A clog prevention device is disclosed for use with a label printing and applying machine. The clog prevention device includes a pair of juxtaposed label guide walls which extend longitudinally up from and at both sides of the printing platen. A label receiving recess is formed in the upper surface of the printing platen between the label guide walls and that recess has a larger width than that of the label strip so that at least both side edges of the label strip may be prevented from contacting the label guide walls of the platen, whereby adhesive at the edges of the label strip does not foul the platen. Label relief grooves are also formed along both sides of the label receiving recess for the same reasons. Openings extend through the platen at the edges of the recess in the upper surface of the platen so that label chips formed when the label strip is pierced or punched during label strip feeding can move away from the label strip. A label receiving recess in the underside of the platen is narrower than the recess on the upper surface and the underside recess guides the separated carrier paper past the platen and centers the label strip over the platen.
