  • Patent number: 4278624
    Abstract: Material such as panels, boards, and flexible sheets are produced and processed while passing between two or more surfaces at least one of which has a thin layer of pressurized fluid in direct contact with the product. While in this process zone, the item is shaped, coated, smoothed, textured, heated, cooled, compressed, dried, and/or impregnated. For example, expandable resin is deposited in a continuously formed bag of upper and lower sheet material so that the resin may expand and cure as it is drawn in through a fixed rigid mold having upper and lower (and perhaps side) porous material walls through which pressurized fluid is passed to provide a fluid bearing support and molding surface. The temperature, pressure and flow of the fluid is monitored and controlled separately at spaced locations along the length of the mold to control curing rate, foaming rate, surface characteristics and resistance of material moving through the mold.

    Abstract: An apparatus for instruction in the techniques of blow molding includes an air cylinder actuated ram parison extruder secured atop a frame carrying a low mass mold set. The mold set includes two thin wall mold segments mounted for reciprocal travel toward a closed position at a molding station. Each mold segment is adjustably secured to one of a pair of webbed, heat dissipating jaws with each jaw being adjustably mounted to a worm-driven carriage. Mold segment set up is accomplished by loosely mounting the jaws to their respective carriages and the mold segments to their jaws; the jaws are brought toward one another to close and align the mold segments. With the segments closed and registered, they are then tightened to the jaws and the jaws to the carriages thereby assuring repeated registration of the mold segments during molding cycles.

  • Patent number: 4212609
    Abstract: A method and machine for producing a configurated and specified weight food product in die cavities of a rotary die roll, each of the die cavities being defined by a configurated side wall and a porous bottom wall. During each revolution of the roll a batch of the product is forced into each cavity as the cavities pass beneath a hopper. Upon continued rotation of the roll, the bottom walls of the cavities are moved outwardly so as to force the configurated products from the die cavities. Tempered air at a controlled temperature and at a pressure above that of the atmosphere is directed through the porous bottom walls while the bottom wall is extended so that the configurated product is forced off of the wall and onto a conveyor located beneath the die roll. To facilitate cleaning of the porous dies, the die roll is so constructed that hot water may be directed through the air flow passage during cleaning and the porous bottom wall dies of the drum may be easily removed from the drum without drum disassembly.

The grooves are of uniform width and depth, and extend radially inwardly from the outer peripheral surface of the roller. A block of approximately the same width and length of each of the grooves is mounted for reciprocating movement in each of the grooves. As the roller is rotated each block is reciprocated radially of the roller within its groove by the interengagement of cam rollers projecting from each end of each block and cam tracks mounted adjacent opposite ends of the roller. Each groove is filled with dough when it is in its upper vertical position and its block is in its lowermost position within the groove. The dough is discharged from each groove on to a conveyor belt as the block within the groove is moved toward the periphery of the roller.

  • Patent number: 4195048
    Abstract: An absolute-coded angular position indicator coupled to the shiftable one of two mold-clamping plates, produces a position signal indicating the position of the shiftable plate. This signal is applied to one input of a subtractor, whose output signal is displayed on a numerical display. The subtracting input of the subtractor receives a corrective signal from a manually set decades switch arrangement. When no mold is present between the clamping plates and the latter are pressed into direct contact with each other, the displayed numerical value is zero. When a mold is clamped between the plates, an non-zero value is displayed, and the set-up technician sets the decades switch arrangement to the displayed value. As a result the displayed value goes to zero. The output signal of the subtractor is furnished to control elements which must control machine operations in dependence upon the height of the particular mold being employed.
