Abstract: A separator for blow-molded parts, which separator includes a plurality of endless belts movably supported between a pair of horizontally spaced pulleys, one of which is a drive pulley. The belts, preferably of circular cross section, have upper reaches extending in approximately parallel but sidewardly spaced relationship to define small gaps therebetween through which scrap parts can pass. The other parts remain on the belt and are transported to a discharge location. The adjacent belts are preferably driven at slightly different speeds to facilitate agitation and dislodgement of scrap parts so that they can move into and through the gaps. The ends of the belts are supported by rotatable end idler pulleys, alternate ones of which preferably have exterior belt-engaging profiles which are noncircular relative to the rotational axis to effect cyclic vertical displacement of the upper reaches of alternate belts.

Abstract: A belt-type separator for effecting separation of blow-molded parts, which separator preferably includes at least two endless belts movably supported on and between a pair of horizontally spaced pulleys, one of which is a drive pulley. The belts, preferably of circular cross section, have the upper reaches extending in parallel but slightly sidewardly spaced relationship to define a small gap therebetween through which scrap parts can pass. The other parts remain on the belts and are transported to a discharge location. The belts are preferably driven at slightly different speeds to facilitate the agitation and dislodgement of the scrap parts so that they can move into and pass through the clearance spaces between adjacent belts.

Abstract: An apparatus for submersing a plurality of elements in a liquid, including an upwardly open tank, a quantity of liquid in the tank, and a perforated plate having a guide surface on the underside thereof and extending from a first location in the region of the surface of the liquid to a second location spaced below the surface of the liquid. A submersion conveyor provided in the tank includes an endless belt having a plurality of spaced and transversely extending cleats, the submersion conveyor being positioned so that, during at least a portion of the path of travel of the cleats, the cleats are adjacent and move along the guide surface from the first location to the second location thereon. Thereafter, cleats on an endless belt of a further conveyor move the elements through the tank below a further guide surface portion on the underside of the perforated plate and then move the elements upwardly and out of the tank.

Abstract: A belt-type conveyor having an endless belt supported on a pair of spaced end rollers. The upper reach of the belt is adapted to have articles supported thereon for transporting thereof. A drive system is interconnected to both end rollers to simultaneously rotatably drive same, which end rollers in turn drive the belt. This drive system permits the upper reach of the belt to be maintained relatively free of tension so that the upper reach will readily conform to a guide structure which is positioned thereunder for slidably supporting same. The conveyor is particularly suitable for use as an inclined conveyor to permit lifting of articles on the upper belt reach, which upper reach can be bent upwardly from a horizontal position without requiring top guide rails or other hold-down devices.

Abstract: Method and means for engaging a molded component by an externally positioned handling device during an injection molding operation and prior to the opening of the mold. A passageway is provided to the exterior of the mold from a mold cavity which latter may be a cavity for the forming of a molded part or it may be a runner, the sprue or some combination of two or more thereof. A handling device is positioned adjacent the mold to receive molten material from said passageway during the molding operation and thereby establish a solid connection from said handling device to said molding component. When the mold opens, said molding component may then be removed from the mold with control thereover retained by the handling device for such further processing as desired.
