A molding-forming method, a molding mold, and a molding production apparatus with which efficient burrs removal is possible without requiring a large apparatus. A molding production method includes, in addition to a molding being formed inside a mold, burrs formed around the molding are separated from the molding. After formation of the molding, air is blown inside the mold on at least a portion of the burrs formed around the molding to cool the same, a projecting member is projected toward the cooled burrs, and the burrs are separated from the molding. After pressing the burrs toward the projecting member by the air blowing, the burr is pressed toward the mold surface facing the projecting member by projection of the projecting member to separate the burr from the molding.

A heating element for resistance welding of thermoplastic components includes an electrically conductive sheet with cut-outs, wherein a ratio of cut-outs to electrically conductive sheet changes at least along a transverse direction of the sheet, so that an electrical resistance of the sheet has a maximum at a center of the sheet. A welding kit includes the heating element and an electrical insulation layer. A method of manufacturing the heating element, and a method of employing the heating element for welding two thermoplastic components to one another are disclosed.

The method for producing a container consisting of a rigid outer container and a deformable inner bag. A first screw conveyor supplies a first thermoplastic plastics material for the outer container and at least a second and a third screw conveyor supplies at least a second and a third thermoplastic plastics material for the inner bag to an extruder which coextrudes a parison consisting of at least the first, second and third layers. The parison is inflated by a pressure medium to bring it into contact with the wall of the blow mould, where excess material below the welded seam is cut off and the container is removed from the blow mould. The second thermoplastic plastics material forming the outer layer of the inner bag consists of a material which, in the hardened state, has a rough surface having microscopically small elevations and depressions.

A thermoplastic pre-container, typically a blow molded piece, is provided to form several hollow bodies. The pre-container is elongated along a central axis and includes a bottom section, an opened section and in-between at least one hollow body section. A plurality of circumferential grooves are provided in a pre-container sidewall, each with a bottom line formed in a virtual plane perpendicular to the axis. The bodies are obtained after cutting the pre-container in a direction transverse to the central axis and severing the end sections. Due to the cutting at several of the circumferential grooves, a top opening and a base opening are respectively obtained for at least two hollow bodies, each opening being delimited by an annular inner rim of a body flange.

A web transport assembly for moving flexible sheet material in a manufacturing process. The web transport assembly comprises first and second gripper chains spaced apart from one another to define a path of travel of the flexible sheet material, each of the gripper chains having a plurality of saddle links and a plurality of gripper links. First and second parallel rail structures are respectively aligned with the first and second gripper chains. In addition, upstream and downstream hubs are associated with each of the first and second gripper chains to define a continuous loop about which the associated gripper chain extends. At least one of the hubs includes a driven sprocket having a plurality of teeth engaging the associated gripper chain. The saddle links have a pair of spaced apart extension portions defining a spaced in which an associated one of the rails is received. The gripper links have a gripper mechanism that is configured to clamp a side of the flexible sheet material.

Compression mold assembly for forming a preform of a cascade includes first and second die elements and an axis of alignment. Line of removal of a formed preform is positioned perpendicular to a plane perpendicular to the axis of alignment. First die portion includes first curved surface forming interior surface of first strong back and second die portion includes first curved surface forming interior surface of a second strong back of a cell of a formed preform. Second die portion includes second curved surface forming an interior surface of a first vane on forward side of the cell of the formed preform and first die portion further includes first wall member which extends along line of removal and a second wall member which extends angularly from first wall portion forming an interior surface of a second vane positioned on an aft side of the cell.

The method includes unwinding a thermoplastic film from a roll, stretching the thermoplastic film in the machine direction so that it plastically deforms and decreases in width, slitting the stretched thermoplastic film into the multiple mechanical fastening strips, and winding the multiple mechanical fastening strips into multiple rolls. The thermoplastic film has a first surface and a second surface opposite the first surface, and the first surface of the thermoplastic film bears a plurality of male fastening elements. In the method, the unwinding, stretching, slitting, and winding are completed in-line.

A method for manufacturing a fiber formed body includes forming a fiber board into a predetermined outer shape while forming a pattern on an outer surface of the fiber board by compressing the fiber board, a forming at least one positioning member by compressing the fiber board, and positioning, relative to a cutoff device, the fiber board using the positioning member, and cutting off a cutoff target part of the fiber board using the cutoff device. In the method for manufacturing the fiber formed body, formation of the pattern during the forming of the outer shape and formation of the positioning member during the forming of the positioning member are simultaneously performed.
