Glue application device for a labeling machine

Glue application device with at least one gluing roller (4) which can be driven in rotation around its roller axis, and with at least one glue application and spreading element (3) with a glue dispensing point which is in communication with a connection (16) for the delivery of the glue to apply glue on a cylindrical peripheral surface of the gluing roller (4) that concentrically surrounds the roller axis and is moved past the glue dispensing point, wherein said glue application device comprises an overflow (14) which is formed between the connection (16) for the feed and delivery of the glue (8) for the removal of an excess quantity of glue that is not deposited on the gluing roller (4) into an overflow duct (15), preferably into an overflow (15) that leads into a glue reservoir (21) that supplies the glue application device.

Glue application device with at least one gluing roller (4) which can be driven in rotation around its roller axis, and with at least one glue application and spreading element (3) with a glue dispensing point which is in communication with a connection (16) for the delivery of the glue to apply glue on a cylindrical peripheral surface of the gluing roller (4) that concentrically surrounds the roller axis and is moved past the glue dispensing point, wherein the glue dispensing point is formed by a glue chamber (8) which has the glue application and spreading element (3) in the vicinity of a contact surface (7) which is in contact against the peripheral surface of the gluing roller (4), and which is closed on its side facing the gluing roller (4) by the peripheral surface of the gluing roller (4), wherein said glue application device comprises a heater (6) disposed within the glue application or distribution element (3).
