Abstract: An improved apparatus for making dough envelopes containing filling. The apparatus is molded from plastic and includes a frame structure having a plurality of interconnected hexagonal molds so as to form a honeycomb type structure. Each hexagonal mold includes six inclined cutting edges which are connected around a central inverted conical chamber. The inverted conical chamber partially supports the dough envelope during formation to produce uniformly shaped and aesthetically pleasing envelopes. Further, horizontal pasting faces are provided in the corners of each mold between the conical chamber base and cutting edges lower edges. These horizontal pasting faces in combination with the cutting edges provide a strong and uniform seal around the dough envelope edges.

The forming roller is generally cylindrical and is provided with a cutting grid around its curved surface and a number of ravioli forming areas located within the interstices of the cutting grid. Each ravioli forming area includes a centrally located, saddle shaped relief surrounded by at least one, but preferably two, sealing ridges.

Abstract: A method for preforming magnetic drum material involves the use of a hydraulic press and sleeve which in turn compresses the material and then cuts the material into a specific shape. This process is repeated until the material builds up in the sleeve to the required charge thickness. This method has improved the molding process by eliminating air and gas voids in the molded magnetic drum.

Abstract: Food products are processed prior to consumption in a press form having multiple, separate, pre-selected planar food product molds, each having tapered walls, providing easy food product removal. The food products can have pastry dough exteriors and can be filled with selected food fillings held in position and shaped by dough crust exteriors. Multiple press form food product molds have regular planar shapes disposed multiple in a tray. One face of each product mold has a cutting-edge knife disposed thereon, conforming to the mold interior shape. The cutting-edge knife can be disposed at either mold wall taper terminus. A cooperatively shaped, one-piece negative pusher plug mold, sized to intercept each one of the multiple food product molds disposed in the tray, is used to cooperatively push each food product out of the molds in the tray simultaneously.

Abstract: A plurality of reinforced plastic parts are simultaneously molded from separate bundles of resin impregnated strands wound about individual frame sections of a substantially planar frame assembly. A loading station includes a dual-acting elongated carrier engaging the multi-sectioned frame assembly and initially rotatable to wind the bundle of strands thereon. Subsequent reciprocation of the carrier delivers the wound frame assembly to a molding station provided with a plurality of mating pairs of molded sections and having displaceable frame supporting and bundle clamping assemblies for engaging the wound frame assembly and severing opposite ends of the bundles as the mold sections close within the individual frame sections.

Abstract: A method and apparatus for lining the interior of a container with plastic sheet material. An open topped container is elevated upon a support through a passage in a lower die member into contact with the under surface of a sheet of heated thermoplastic material overlying the upper end of the passage. A plug assist member is then employed to deform the sheet into conformation with the interior of the container. Upon withdrawal of the plug assist member, an upper die member is lowered into shearing relationship with the lower die member to shear the sheet around the upper periphery of the container. The support, with the lined container in place, is then further elevated to raise the lined container upwardly through the opening thus sheared in the sheet and through a passage extending vertically through the upper die member. The plastic lined container is discharged from the apparatus by pushing it transversely across the flat upper surface of the upper die member.

Abstract: A mold provided with cutter means movable relative to the other elements of the mold to sever an extension portion of a hollow article formed in the mold from the remainder thereof while the article is in the mold and without effecting substantial movement of the article relative to the mold.

Abstract: In the formation of an elastomeric tube or the like on a toroidal core, elastomeric material is applied to the core generally along one side of the core, and force-applying means are utilized to press annular portions of the so-deposited elastomeric material onto the core. Cutting means are also included for cutting away elastomeric material not deposited on the core. The core and elastomeric material deposited thereon are then turned over and the operation is repeated, whereby elastomeric tube means or the like are provided on the toroidal core.

Abstract: Netting is made from thermoplastic threads on a machine which applies to a plurality of spaced longitudinal strands at least two spaced transverse strands and bonds the latter to the former by individual moulded masses of plastics material. The rows of die assemblies for this moulding operation are arranged in one or more oppositely directed pair and are supplied with transverse strands by drawing such strands across the longitudinal strands and then transferring the required lengths of strand laterally into the respective die assemblies from opposite directions. The longitudinal strands are advanced intermittently by cooperating grippers, preferably at both ends of the machine. Sets of releasable grippers at the input and the output ends of the machine are reciprocable between positions respectively upstream and downstream of other sets of releasable grippers at the ends of the machine.

Abstract: A conveyor belt is formed with depressions which are bounded by sealing edges, and tiles corresponding to the outline of the respective depressions are continuously admitted from above onto the belt and inserted into the depressions so as to be in sealing contact with the respective sealing edges. A layer of hardenable synthetic plastic material is then deposited on the belt over the tiles so that the latter are partially embedded in and united by the layer when the same hardens, thereby obtaining a unitary structure. Subsequently this structure is subdivided in plate elements of desired size.

Abstract: Apparatus and method for applying cover or cladding elements of heat shrinkable plastics material upon the externally screw threaded metal necks of dispensing containers such as toothpaste tubes comprises a rotatable turntable for mounting a succession of containers and presenting them at an insert applying station having means for advancing the tubular open end of a continuous length of synthetic plastics tubing toward a positioned container neck and for operating upon the leading end of the tubing to separate therefrom successive cover or cladding elements of desired length and dispose each on a container neck prior to a heat shrinking operation for permanently securing the elements upon the threaded necks.

Abstract: The process and apparatus for continuously forming glass fiber reinforced products employs a preform produced by drawing continuous glass fibers through a resin bath and stripping die. This preform is then compressed during passage through an elongate molding zone. The molding zone is formed of two, articulated die cavity-containing tracks, the individual mold components of which join at the threshold of the zone to form an elongate, moving compression stage. This stage may be heated to carry out curing of the product during compression thereof.
