Abstract
A container sealing apparatus wherein a strip of closure material can be transported intermittently a desired distance at a time, and this distance is variable in accordance with the size of containers to be sealed to achieve savings in the material without wasting. The closure material is affixed to the opening edge portions of containers at a sealing station, and a closure is blanked out from the material affixed to each container, along the opening edge portion by a cutter before the container is delivered from the sealing station. The closure material is transported by means operable independently of the container transport operation.
