Abstract

The invention relates to an apparatus for cutting film tubing in a machine for applying tubular labels to each of a series of containers that are transported on a conveyor. The film tubing is advanced incrementally through a ring gear and a bore in a platform on which the ring gear is rotatably mounted. A number of pinions with attached cutting blades are rotatably mounted to the platform in positions to mesh with the ring gear. One of the pinions is driven to rotate a single revolution when the film tubing has been advanced. The driven pinion causes the additional pinions to rotate through rotation of the ring gear, causing the blades to cut the film tubing.
