Abstract: A nozzle for an injection molding machine with a common nozzle outlet chamber to control the injection of at least two plasticized plastic components in a mold, where each plastic component is produced in a separate plasticizing unit and each such unit is connected by the shortest path to at least one separate nozzle inlet which in turn is connected within the nozzle by means of a separate channel to the common nozzle outlet chamber. Each channel is provided with its own shutoff valve that can be actuated independently in such a manner that each infeed channel extends from its nozzle inlet in a straight line to the related shutoff valve, and from it in turn over an outfeed channel in a straight line to the common nozzle outlet chamber.

Abstract: A sports shoe such as a soccer shoe having an injection molded sole molded to an inner sole, the sole having open spaces and injection molded cleats molded to the inner sole.

Abstract: A machine for the direct soling of shoe uppers having at least one molding station is provided for conveniently and effectively removing the molding sprue from the die mold which typically remains after each injection molding process. Such is effected by disposing the heel end of each shoe last toward the front working end of the machine at which the operator is stationed. And, the injection molding unit provided for the machine includes a rotary valve which automatically closes as the feed passage of the unit is moved out of alignment with the mold cavity inlet passage, and is automatically open when the feed and inlet passages are aligned in an injection molding operating position of the unit.

Abstract: An apparatus for the lasting of shoe uppers or shoes onto shoe lasts, and for the removal of the completed shoes from the shoe lasts, includes a two-part shoe last having a front toe part and a heel part, a fixing device for removably mounting the front toe part on the frame, and a coupling device for movably and releasably mounting the heel part of the frame, the coupling and/or fixing device including pivotable clamping bars, and a height-adjustable mechanism for moving the heel part and its coupling from a rest position toward the front toe part, and back to such rest position.
