A method of making a metal foil heater comprising transferring a line image of a heater circuit to cutter and cutting the foil into a metal foil construction before affixing plastic sheets to both sides while attaching wires configured to supply current to the heater.

The disclosure relates to a deep-drawing apparatus for deep-drawing a continuously fed film web, an associated packaging machine, and a corresponding method. A cyclically sequenced forming station, which runs along from a start position to an end position and runs back from there to the start position is provided, wherein individual format plates are sequentially firstly connected up to a forming vacuum device and then with a following holding vacuum channel. The forming vacuum device is part of the cyclically moved forming station. The holding vacuum channel includes two interlocking telescopic channel portions, a first telescopic channel portion being part of the cyclically moved forming station, and a second telescopic channel portion being mounted statically relative to the fixed machine frame.

The invention relates to a mold for manufacturing a plastic part, including a first element and a second element forming, in the closed position of the mold, a cavity corresponding to the part to be manufactured, in which the second element includes at least one system for making molding openings in said part, said system including at least one member forming a cavity of an opening for the finished part, said member being movable relative to the second element in the closing direction of the mold, between a retracted position and an position extending into the cavity. The system includes at least one positioning means for positioning the member in the extended position relative to the first element, said system being sized such that, in the extended position of the member, the distance between a surface of the member bearing on the plastic material and the first element enables the formation of a thin layer of plastic material having a repeatable thickness.

A method of bonding a second object to a first object includes: providing the first object having a thermoplastic liquefiable material in a solid state; providing the second object having a surface portion that has a coupling structure with an undercut, so that the second object is capable of making a positive-fit connection with the first object; pressing the second object against the first object with a tool that is in physical contact with a coupling-in structure of the second object while mechanical vibrations are coupled into the tool; continuing to press and couple vibrations into the tool until a flow portion of the thermoplastic material of the first object is liquefied and flows into the coupling structures of the second object; and letting the thermoplastic material re-solidify to yield a positive-fit connection between the first and second objects by the re-solidified flow portion interpenetrating the coupling structures.

The invention relates to a method for producing a body component (1) for a motor vehicle (2), said body component (1) being made of a main body (3), formed from a batt that is embedded in a plastics matrix, and comprising at least one air-removal device (4), in particular for removing air from an interior (5) of the motor vehicle (2). The air-removal device (4) comprises at least one ventilation opening (7) that can be reversibly sealed by means of at least one ventilation flap element (6).

A blow-molding plastic bubble-generating device is provided, including a board-like shell body. The board-like shell body is formed through blowing a hollow embryo placed in a mold, the hollow embryo is blown and expanded, the hollow embryo is penetrated through by a plurality of needle posts on an inner wall of the mold to form the board-like shell body, the board-like shell body is integrally formed and hollow and has a shell wall which completely and continuously surrounds the board-like shell body, and the shell wall has a plurality of through holes.

A hydroformed composite material includes an expanded spun bonded nonwoven layer having a loft of at least about 1.3 times greater than an original loft of an original unexpanded spun bonded nonwoven web from which the expanded spun bonded nonwoven layer was created, and an air permeability of at least about 1.2 times greater than an original air permeability of the original unexpanded spun bonded nonwoven web. The hydroformed composite material includes a formed film layer that includes a plurality of extended cells containing continuous fibers and/or fibrils of the expanded spun bonded nonwoven layer.

A method of joining first and second layers of material according to the principles of the present disclosure includes applying a layer of adhesive between the first and second layers and allowing the adhesive layer to at least partially cure. The method further includes piercing the first layer with a headless end of a rivet after the adhesive layer is cured, deforming the second layer with the headless end of the rivet, and bending the headless end of the rivet radially outward.

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.

A joining method for joining a resin member and a metal member by heating is provided. Joining of the resin member and metal member is performed by heating a joining interface of the resin member and metal member to a temperature in a range of equal to or higher than a decomposition temperature of the resin member and lower than a temperature at which gas bubbles are generated in the resin member and by cooling a surface of the resin member on the opposite side from a joining surface thereof with the metal member to a temperature that is lower than the melting point of the resin member.
