Beverage bottling or container filling plant having a beverage bottle or container labeling machine, and a beverage bottle or container labeling machine

A container labeling machine gluing apparatus comprising:

• a rotatable glue roller being configured to apply glue to labels;
• a glue scraper configured to scrape glue off of said glue roller;
• a glue dispenser being configured to dispense glue onto said glue roller;
• a glue thickness adjuster being disposed downstream of said glue dispenser and being configured to adjust thickness of a glue layer on said glue roller prior to application of glue to labels;
• said glue thickness adjuster comprising a glue contact element configured to contact glue on said glue roller;
• said glue thickness adjuster being adjustable to permit adjustment of the position of said glue contact element with respect to said glue roller;
• said glue contact element being disposed upstream of remaining portions of its glue thickness adjuster in the direction of rotation of said glue roller, and said glue contact element points in the direction opposite the direction of rotation of said glue roller and away from remaining portions of said glue thickness adjuster;
• said glue contact element comprising a first edge and a second edge;
• and
• said glue thickness adjuster being configured to be adjusted to move said glue contact element between at least a first position in which said first edge is disposed closer to said glue roller than said second edge and is in contact with glue on said glue roller to form a first layer of glue, and a second position in which said second edge is disposed closer to said glue roller than said first edge and is in contact with glue on said glue roller to form a second layer of glue which is thicker than said first layer.
