A GLUE APPLICATION UNIT FOR A LABELING APPARATUS

摘要

There is described a glue application unit (1) for a labeling apparatus (2) comprising: - a glue roller (5) which presents an outer lateral surface (6) adapted to apply melted glue on label sheets (3); - a glue feeding device (7) for feeding melted glue to the glue roller (5); - a glue distribution bar assembly (8) arranged adjacent to the glue roller (5) and having a glue feeding channel (22), selectively connected to the glue feeding device (7), and an outlet section (24) adapted to selectively transfer the glue from the glue feeding channel (22) to the glue roller (5); wherein the glue distribution bar assembly (8) comprises a glue distribution bar (26), carrying the outlet section (24), and a bar support post (25) which presents the glue feeding channel (22); the glue distribution bar (26) is removably coupled onto the bar support post (25) in such a way that it at least partially covers the bar support post (25).
