Abstract: A sealing machine is disclosed of the type which applies closure caps to containers at extremely high speeds by moving filled containers successively through a cap feeding station, a cap applying station, and a cap sealing station. The machine is characterized by improvements in its several sections which permit it to operate effectively at increased speeds, and at the same time provide for an improved adjustability for differing package sizes. The adjustability provides for independently operable adjustments for the sealing chamber height and for the width and height of the side belts which move the containers through the sealing chamber. Additionally, an improved cap feed is described with a cap feeding star wheel and improved container guiding side belts are also disclosed.

Abstract: A method and means are described for improving the feeding of closures and containers to a sealing machine. Sealing machines utilize container controlled trips for controlling the stop and start of the closure feed to the sealing section to synchronize the container and closure feeds. Means is provided for compensating the action of the container controlled trip in accordance with the operating speed of the sealing machine. This permits changes in the machine speed to occur or to be made while retaining the necessary synchronization of the cap and the container feeds.
