A gluing arrangement for applying glue to labels in a labeling machine, which gluing arrangement has a heated roller element and one or more temperature sensors which sense the temperature of a portion of the roller element. The temperature sensors are protectively sealed against contamination and mechanical damage, such as by being sealed inside the body of the roller element. The gluing arrangement also has a heating arrangement which includes one or more induction coils for heating the roller element. The heating arrangement and/or induction coils are positioned within the roller element such that they are surrounded by either an inner or outer surface of the roller element.
