Abstract
Apparatus for wrapping shrinkable plastic labels about bottles as they are moved in a single file. As the bottles exit the wrapping machine, they are resting on a moving belt conveyor which is driven in the direction of a heat shrinking tunnel. In order to have the bottles, with the labels applied, pass through a circulating hot air, infrared tunnel in properly spaced intervals to assure proper shrinkage of the tubular labels, a spacing device in the form of a bottle side-engaging set of brushes is used. The brushes have their bristles extending horizontally across the path of movement of the bottles on the conveyor. The bottles are actually pushed at the speed of the labeling machine through the gap between the brushes and therefore the bottles are released by the brushes at equally spaced time intervals and thus become equally spaced on the moving conveyor belt that carries them to the heat shrink tunnel.
