Abstract: Apparatus for loading and unloading a frame bearing a cover material for application to a formed thermoplastic sheet, especially in the production of cover panels for motor vehicles, is associated with a press including two dies for simultaneous moulding of the sheet and application of the cover material thereto, and includes a take-up station disposed outside the press for taking up a frame and a device for automatically transferring the frame from the take-up station to a moulding station between the dies. The device includes a pair of guides supported by one of the dies, the guides extending from the take-up station to the moulding station. The device further includes a frame take-up member mounted for sliding movement along the guides and associated with an actuator for controlling movement of the frame take-up member between the take-up and moulding stations.

Abstract: A transporting apparatus for moving away injection-molded articles from an injection molding machine includes pallets; a charging station for loading the pallets; transporting pallets each individually supporting at least one pallet and coupled thereto for forming a transporting unit; a pallet tower spaced from the charging station for storing a plurality of pallets; an elevator for receiving empty pallets from the pallet tower and loaded pallets from the charging station and being vertically freely movable during loading of the pallets in the charging station; a conveyor for moving the transporting pallets between the elevator and the charging station for transferring empty pallets from the elevator to the charging station and for transferring loaded pallets from the charging station to the elevator; and a positioning arrangement for placing the elevator into such a position during transfer thereto of empty pallets from the pallet tower and transfer therefrom of loaded pallets into the pallet tower that a tr

Abstract: Green concrete products, such as building products, are placed on pallets. Those pallets are transported to a kiln for curing and from the kiln after cure by an overhead crane. Pallets are lowered into and removed from open top kilns layer by layer being supported by movable support ledges, for example rotatable toggles, at each layer position which permit vertical entry and removal of the pallet layers. Three kiln compartments permit continuous production, one being filled, one being emptied and the third curing a load of pallet layers.

Abstract: An improved slipform for use in a machine for casting hollow core concrete planks includes at least one angled baffle plate in the core material receiving ports so as to deflect the core material from directly impacting the lower concrete. This lessens the possibility of tears and holes in the lower layer caused by the core material.

Abstract: A material feed system provided with a plurality of injection molding machines. A filling station is provided and has a resin tank in which resin material is stored, a container to which the resin material is fed from the resin tank, and a coupling device for coupling the resin tank and the container on demand. A carrier having a clamping mechanism runs along a track which is laid so as to pass over the injection molding machines and the filling station. The coupling device is controlled by a control unit. The control unit also controls the movement of the carrier to thereby transport the container by the use of the clamping mechanism and to feed the resin material from the container to the injection molding machines.

Abstract: Apparatus for propelling a succession of pallets in a longitudinal direction has a plurality of pawls for pushing the pallets and spaced apart on a pair of endless drive chains each having a portion extending parallel to a pallet guide means. Each pawl is arranged to move in such a way that in use it engages one of the pallets to push it along the guide means and disengages from the pallet further down the guide means, the movement of each pawl being controlled by an associated cam follower wheel cooperating with one of a pair of longitudinally extending cam tracks. The cam follower wheel can be laterally moved on a shaft to select the appropriate cam track for the type of pallets to be conveyed, so that the apparatus can be easily adapted to e.g. different length pallets.

Abstract: A production line for bitumen cakes comprising sequential processing stations, i.e. a station whereat hot bitumen is cast into basins or pans, a station whereat the bitumen is air cooled, a station whereat the solidified bitumen cakes are shaken out, a station whereat the cakes are packaged in a heat-shrinkable plastic material, and an optional palletization station. The production line is set up to accommodate a plurality of pans which are carried in groups on a plurality of platforms or supporting frames adapted to be cyclically passed through the casting, station, cooling station where they are piled, and shake-out station. The cake shake-out station includes an extraction apparatus equipped with a pusher intended for acting on the outside of the pan bottoms to produce resilient deformation of such bottoms and twisting of the pans to separate the pan from the bitumen cake contained therein.

Abstract: An apparatus for making concrete brick in a manner such that at least both elongated sides of the brick have an antique appearance. In the apparatus a first hopper is provided which discharges coloring material onto an empty pallet that passes below the same. The pallet is moved into a concrete brick-making machine where a plurality of bricks are formed on their sides with the lowermost side in engagement with the coloring material. Thereafter a second hopper discharges coloring material onto the upper side of the bricks and such coloring material on the top is spread lengthwise. The forming of the bricks on the coloring material on the pallet provides a mottled effect on one side of the brick and the spreading of the coloring material provides a streaked effect on the other side so that a different antique appearance is imparted to opposite sides of the brick.

Abstract: A combination die and pallet of honeycombed construction comprising an upper rectangular die plate having frusto pyramidal depressions stamped therein and side and end flanges integrally joined to and depending from the die plate together with a base plate of the same size and shape as the die plate having side and end flanges upstanding therefrom and overlapped by the flanges on the die plate and formed with longitudinal ribs pressed therefrom and extending between rows of depressions in the die plate with the base plate being spot welded on the bottom of the depressions and the overlapping flanges being welded together.

Abstract: A combination die and pallet of honeycombed construction comprising an upper rectangular die plate having frusto conical depressions stamped therein and side and end flanges integrally joined to and depending from the die plate together with a base plate of the same size and shape as the die plate. A plurality of inverted U shaped channel members are interposed between the die and base plates between longitudinal rows of the depressions and welded to the plates. The base plate has side and end flanges that are partially overlapped by the corresponding flanges on the die plate and welded thereto. The bottoms of the depressions are also welded to the base plates.

Abstract: Apparatus for forming concrete building blocks which is constructed and arranged (1) to minimize sound emissions to the environment of a magnitude which might cause injury to the hearing of the operators, (2) to provide shielding around the major movable components of the machine so as to substantially eliminate potential causes of bodily injury to the operators, and (3) to improve the performance and cooperation of the major components for making concrete blocks. To provide shielding against noise and bodily injury, the frame of the apparatus is constructed in conjunction with sound insulation panels to provide an enclosure around the major movable components of the apparatus, and the frame also supports these components on internal surfaces thereof so as to minimize sound transmission openings to the environment.
