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. Auxiliary equipment which is also part of this invention includes an automatic filler, adapted to move along with lower mold halves carried on a loading conveyor during the movement thereof and dispense metered amounts of a molding composition or mixture, an automatic loader for receiving molds and mold retainers from the loading conveyor and transferring them to chucks on the casting machine, an automatic piercer for providing air escape holes from the molded object just after they have been formed, and means for synchronizing the movement of all of the foregoing apparatus and components.

In-line rotational casting apparatus

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.
