Abstract: An apparatus for making head pieces for containers with a membrane of laminate having a metallic barrier layer, is designed to make one-piece head pieces, of a thermoplastic material with a mouthpiece neck, a cone-like breast part next to it, a ring-shoulder next to the breast part, a ready-made round plate and a membrane of a laminate with a metallic barrier layer. From a tape of laminate with a metallic barrier layer, using a deep drawing operation, the round plate is produced in a form representative of the outline of the head piece to be produced, is stamped out and is then run down into a mold. At the same time as the lowering the membrane is stamped out of the center part and is kept in position. After this thermoplastic material is placed in the mold and then the membrane is lowered into its last position in the mold and at the same time as the lowering of the membrane pressing of the thermoplastic material in the mold takes place.

Abstract: Sticks of foamable thermoplastic material are provided with grooves in at least one surface. These grooves extend width-wise of the stick. In addition, the grooves are disposed in equi-spaced relation along one surface of the stick, or in spaced-apart series or groups on only one surface, or in series or groups on opposite surfaces and in spaced-apart relation. Upon foaming, the sticks form foamed elements of various shapes, each of which has at least one curvilinear portion such as, for example, a corkscrew shape, an annular shape or shapes with reverse bends.

Abstract: Dough-dividing and forming apparatus particularly adapted for forming toroid-shaped articles such as bagels, or the like, is disclosed. A first rotary plate member containing a plurality of cylindrical openings receives a cylindical ribbon of dough into the openings and shears the dough into disc-shaped dough lumps. The dough lumps are subsequently flattened in the center to form a web and pierced to form a generally annular shape. During the piercing operation, the dough lumps are transferred to a second rotary plate member carrying a plurality of tapered, cylindrical forming cups. As the second plate member is indexed between rotary positions, a plurality of cylindrical mandrels are repeatedly thrust into and out of the forming cups to roll the dough lumps internally along the length of the forming cups whereby the desired shape is formed.

Abstract: An arrangement for the processing of a moving material web, in particular for the creasing or punching of an extruded material web made of plastics. In the manufacture of such material webs a number of operational steps take place directly in conjunction with the manufacture of the web itself, and the fact that for reasons of quality as well as of manufacturing technique the extrusion process cannot be interrupted makes it necessary to attend to any changes in the crease pattern etc. during operation. The arrangement in accordance with the invention makes this possible, in that the material web can be brought into contact optionally with different pairs of processing rollers with the help of a pair of counter-rollers supported in a swivelling cradle, any pair of unused rollers being freely exchangeable against a pair of rollers with a different creasing pattern.

Abstract: In a moulding apparatus for producing a plastics material container matrix, a lower mould member defining a bore from its lower surface to its upper surface, die means slidably displaceable within said bore for deforming said plastics material, cutter means slidably displaceable within said bore defining at least one cutting edge extending obliquely to the longitudinal axis of the cutter means, and an upper mould member having a pressure member displaceably mounted thereon, the lower surface of the pressure member defining a cavity aligned with said bore in said lower mould member, which cavity receives at least a portion of said cutter member and die means when they are displaced.

Abstract: A hinged carton integrally molded of polystyrene foam and adapted to be locked shut by a flap extending upwardly from the bottom part of the carton inside a side wall of the carton cover and carrying one or more prongs so that the latter will be biased outwardly to snap into a corresponding number of holes provided in said cover side wall, the ruggedness of said carton being materially enhanced over similar cartons of the prior art by the local beefing up of said cover side wall in the immediate areas bordering said holes incidental to the functioning of a novel method of and apparatus for manufacturing said carton. Said apparatus is embodied optionally in a forming tool or in a form-and-trim tool and embraces relatively vertically reciprocable carton shaping matched-molds operating on a heated thermo-plastic web of polystyrene foam to produce one or more entire cartons with each reciprocation.

Abstract: A method of manufacturing packaging-container blanks is disclosed which method includes forming a substantially continuous sheet of blanks which sheet comprises a substrate and a coating material attached to said substrate. The coating material at the edges of the blanks of said sheet either extends beyond the substrate or is unattached to the substrate adjacent the edge, or both. The sheet of blanks is manufactured by extruding a molten thermoplastic coating material onto the substrate between two revolving cylindrical rolls. The substrate and the coating material are joined in such a manner that at spaced, selected intervals, elongated zones are provided where they are unattached to each other.

Abstract: A method and apparatus for making ceramic articles, particularly adapted for making roofing tile of S-shaped cross section, wherein a clay extrusion of essentially hollow triangular shape form three sets of tile having severable connections along the apices of the triangular extrusion, each set being S-shaped and supported, as extruded, by a core of corresponding shape; the axial movement of the extrusion being stopped intermittently while serrated blades conforming to the core are pressed radially against the core to score the extrusion and form severable connections dividing each set of tile; the extrusion being severed at selected transverse planes to produce a multiple tile unit for kiln heatment, the tile unit including integral but severable end portions forming kiln furniture for supporting the multiple tile units.

Abstract: The method of forming flat dough pieces for producing flat perforated crackers by placing a thin continuous sheet of cracker dough on a fabric belt and cutting the dough with a die which cuts circles in the dough sheet and simultaneously presses the cut out dough sections against the fabric belt with sufficient force to cause them to adhere thereto. The die also cuts the dough sheet into longitudinal strips and scores the strips to define individual product pieces. The dough strips are lifted off the fabric belt and thus separated from the cut out dough sections which are subsequently removed from the belt by a scraping blade.

Abstract: Apparatus for continuously making corrugated plastic pipes having enlarged coupler collars on one end thereof by continuously extruding a tube of plastic material into a molding zone especially constructed to mold the tube into a series of successively closely spaced body-forming lengths of annularly corrugated pipe with short integral relatively enlarged sleeves interconnecting adjacent body-forming lengths. The thus molded tube is severed along a line about halfway between opposite ends of each successive sleeve to form each sleeve into a pair of separate coupler collars, and the molded tube also is severed along a line about halfway between opposite ends of each corrugated body-forming length thereof. The molding zone is constructed so as to form a plurality of latch members integral with and extending interiorly from each coupler collar, which latch members are adapted to engage the ribs on the opposite end of another like pipe for releasable connection therewith.
