Abstract: A shrink system for a labelling system includes a return duct and a make up duct connected to the inlet of a fan. A valve regulates the temperature of air supplied to the inlet by varying the proportion of air flow between the return and make up ducts. The output of the fan is supplied to a nozzle configured to entrain ambient air with the outlet from the nozzle.

Abstract: A labeling machine includes a knife station for severing labels from a roll. The knife station can be swung on a pivot to allow access to the stationary and rotating knife. Adjustment is made at the stationery knife by varying the separation of a pair of bifurcated arms. Labels are held on the labeling head by a vacuum system that varies the vacuum as the head rotates past the glue station. The glue station has a glue roller supported against lateral forces at its lower edge on a bearing. Its upper edge is supported on an axially floating bearing.
