  • Patent number: 4436500
    Abstract: Continuous hollow object casting machine comprises a plurality of chucks with means to convey the chucks through a helical path along a longitudinal, preferably a closed longitudinal, path, in the course of which the chucks are also rotated about an axis perpendicular to the primary helical path and the rate of movement there along being devised to permit substantially complete hardening of a molding material in molds carried by the chucks so that casts, with molten material therein, may be loaded at one end of the path and unloaded, with a hollow object molded therein, at the other end of the path.

  • Patent number: 4214419
    Abstract: In a packaging apparatus, articles are collated and formed into a module on a carriage assembly and are transported into a draped wrapping film and to means for sealing the wrapped module. Common movement of the sides of the carriage assembly are provided so as to ensure the stability of the collated article pattern. The draped wrapping film is under tension and is aligned with respect to the direction of travel of the carriage assembly. Side and transverse rear sealing of the wrapped module is provided, and the means for rear sealing the module also cuts the wrapping film and splices the unused wrapping film for return to its draped position. The wrapped and sealed module is transferred by a conveyor means from its wrapping position to a means for shrinking the wrapping film over the article module.
