  • Patent number: 10518917
    Abstract: The present invention is directed to an apparatus for loading stacks of container lids into an associated lid-applying apparatus, as typically found in a container filling facility. The apparatus includes a reciprocably movable carriage which is positioned generally above the lid-applying apparatus. The carriage can be positioned in a first, loading position, which is generally offset from the apparatus for convenient placement of the lid stacks by operators. The carriage can then be moved over the lid-applying apparatus to a second, unloading position. The carriage includes movable lid supports, which then open to release the lid stacks downwardly onto the lid-applying apparatus. In the preferred form, vertically movable lid cradles extend upwardly from the lid-applying apparatus, and receive the lid stacks from beneath carriage. The cradles then move downwardly, carrying the lid stacks downwardly, for transfer of the stacks onto the lid-applying apparatus.

  • Patent number: 5669205
    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.
