Patent number: 4759703Abstract: The spraying equipment is arranged at a station provided with means for opening and closing the die, e.g. at a preheating station of a plastic injection molding installation. The equipment comprises a spray arm with nozzles, movable, e.g. hydraulically in horizontal and vertical directions, which arm is connected to a spray medium supply. This supply as well as the drive of the spray arm, is automatically controlled via the computer of the injection molding installation in such a way that with the die open, the spray arm is automatically moved into operating position between the die parts and is manufactured in accordance with the tool data picked up by the computer. After completion of the spraying the arm is retracted into an inoperative position outside the die. Operating personnel is superfluous.Type: GrantFiled: October 30, 1986Date of Patent: July 26, 1988Assignee: Netstal-Maschinen AGInventors: Rudolf Krebser, Hans Leuzinger

Patent number: 4698006Abstract: Apparatus for use in the reaction moulding of plastics materials in which two liquid components are mixed in a screw type or similar mixer. Mixed material is ejected or poured into a mould via a passageway which latter is one of a plurality of similar passageways arranged radially around a wheel. Each passageway remains in the lowermost (pouring) position for a period of time during which it is reckoned to remain in a satisfactory working condition, and the wheel is then automatically indexed to bring the next passageway into operation. Cleaning structure is employed to clean out the used passageways after a period of time known by experience to be sufficient for the material to be at least partially cured. In this way the passageways can be re-used in a continuous production machine.Type: GrantFiled: March 31, 1986Date of Patent: October 6, 1987Assignee: C. & J. Clark LimitedInventor: George T. Ralphs

Patent number: 4535505Abstract: A method and apparatus are disclosed in which a mold plate is provided for defining a mold opening and in which a foraminous member is provided with rows of apertures communicating between an upstream side and downstream side of the member. Narrow slots connect the adjacent apertures in each row. The foraminous member is disposed with the downstream side adjacent the mold plate and has spaced-apart ribs on the upstream side oriented between, and parallel to, the rows of apertures. Pressurized food material is forced from the upstream side of the foraminous member through the apertures to the downstream side of the foraminous member and into the mold opening as discrete extrudate masses which together define a packed array forming the patty. An agitator bar with spaced-apart teeth is disposed on the upstream side of the foraminous member with a tooth disposed between each pair of adjacent ribs.Type: GrantFiled: May 7, 1984Date of Patent: August 20, 1985Assignee: Holly Systems, Inc.Inventors: Harry H.

Patent number: 4193167Abstract: An improved molding apparatus is provided for forming patties from an agglomerable edible material, particularly meat in frozen flake cut form. The apparatus includes a rotating turret with a plurality of mold cavities and reciprocable pistons. The turret rotates between a feed station where the edible material is fed upwardly under pressure into the mold cavities and a discharge station where the formed patties are ejected and separated by a continuous cut-off band. An improved cut-off band is also provided in which the band is disposed at a slight angle to facilitate its entry into the interfaces between the bottom surfaces of the pistons and the formed patties. The leading corners of the pistons are chamfered to receive the blade. The band is looped between a pair of pulleys on adjustable supports for providing the desired inclination of the band. Scrapers and spray nozzles are provided to maintain the cleanliness of the band and the pulley grooves.Type: GrantFiled: November 9, 1978Date of Patent: March 18, 1980Assignee: Armour and CompanyInventors: Gerald J. Orlowski, Rodney D. Wicklund, Richard D. Sandlas, Walter W. Weibler

Patent number: 4168140Abstract: For convenience in handling, etc., use is made of a concrete or similarly fabricated member which, although actually a single rectangular block-like member, has a surface line impression effectively simulating a selected arrangement of plural individual pavers or bricks, thereby giving the desirable impression that the construction is formed by said individual bricks, rather than by the fewer number of construction blocks. In accordance with the present invention, the line-forming means, which simulates the individual bricks, is retracted from its position impressed into the concrete mass or mixture through slots in a press-plate having wiping surfaces which removes any adhering concrete therefrom, and thus the shaping contour of said line-forming means is properly preserved for succeeding brick-simulating service. The term "brick" as used herein is intended to broadly encompass regular as well as irregular shapes, such as stones.Type: GrantFiled: September 12, 1977Date of Patent: September 18, 1979Inventors: John D. Fontana, Louis R. Fontana

Patent number: 4065241Abstract: Improvements in molding apparatus and method for forming a plurality of patties from a mass of agglomerable edible material such as, chopped meat, fish, poultry, vegetables, or the like. The molding apparatus includes a rotatable turret having a plurality of mold cavities positioned therein with a piston reciprocably mounted in each cavity. Upward piston reciprocation forms a mold in the lower portion of the cavity. An improved food-feeding mechanism having an enlarged end opening in communication with the cavity pushes the edible material into the mold over a wide portion of the turret rotation. The piston reciprocates upwardly while in communication with said food-feeding mechanism to draw food material into the mold and avoid air pockets in same. As the turret rotates and the piston reciprocates downwardly to expel the patty, an improved continuous wire band patty cut-off mechanism cleanly separates the patty from the piston to which it typically sticks, without deforming the patty.Type: GrantFiled: July 14, 1976Date of Patent: December 27, 1977Assignee: Armour and CompanyInventor: Gerald J. Orlowski
