Abstract: A cartridge of wound-up photographic film has an elongate housing within which the film is received, the housing having an outlet through which the film leader projects. In order to insert the cartridge of film into a cylindrical container it is necessary to wrap the film leader around the housing of the cartridge. A method of inserting the cartridge into the container involves conveying the cartridge into the open end of the container whilst simultaneously rotating the cartridge about its longitudinal axis so that the film leader is brought into engagement with the rim of the open end of the container whilst it is rotating. This causes the film leader automatically to be wrapped around the housing of the cartridge to permit the ready insertion of the cartridge and the film leader into the container. An apparatus for automatically performing the function of inserting the cartridge into the container using this method is also described.

Abstract: The present invention relates to a method of manufacturing a can to receive and to be closed by an easily removable cover merely by the action of vacuum and without the help of any mechanical means. The cover is provided with a sealing gasket, a relief hole and a detachable seal. The upper end of the can is provided with an outwardly wound cord.

Abstract: An intermittently operated, indexing container conveying system is particularly configured for versatile use with an associated container filling apparatus. In distinction from previous arrangements, the present system includes a servo-drive motor for effecting intermittent indexing movement of a container-carrying endless conveyor. Programmable controls of the system facilitate operation of the system for optimizing efficiency, facilitating use of the system with containers of differing configurations, and with food products exhibiting varying physical properties (i.e., such as viscosities). The present system permits acceleration and deceleration rate of the conveyor to be selectively varied, as well as selective variation of indexing pitch and stop points of the conveyor.

Abstract: In order to prevent spilling the contents or fracturing a package being filled, a rigid tray is moved into a filling area by pushers in which the pusher is advanced under controlled acceleration and then deceleration for gently stopping the pusher in contact with or in close proximity to a filled tray. A short time delay in movement of the tray is provided and then the pusher is advanced along with the tray moved thereby under a controlled acceleration into a sealing station. The tray is brought under controlled deceleration to stop in the sealing station at a predetermined position where another short time delay is provided in the stop position of the pusher. The pusher is then retracted to a safe position out of the way in order to permit the sealing of the tray without the interference of the pusher while the tray is sealed. The sealed tray is then transferred to an outfeed area and the sequence is repeated for filling and sealing a following tray.

Lids are then heat sealed to the cleaned flanges, and the sealed containers sterilized.

Abstract: A method is disclosed wherein a lid is engaged to a container by the formation of interlocking waves of lid material and container meterial about the interior rim of the container. The interlocking waves are geometrically aligned relative to the interior of the container so as to maximize the burst strength of the container, and also to minimize the force required to peel the lid from the container. An unheated clamp head is used to clamp the lid structure immediately adjacent a heated seal head used to form the interlocking wave structure about the inside rim of the container. The unheated clamp head prevents any melted portions of the containter or lid from flowing to or towards the outside rim of the container. Interlocking waves of material are thereby prevented from forming about the exterior rim of the container.
