The vacuum sealer includes a base, a cover, a vacuuming device, at least a heating device, at least a heat-resistant element wrapping around the heating device, at least a heat insulation element between the base and the heating device, at least a power provision device, and at least a safety breaker device. The safety breaker device includes at least a safety switch, and at least a trigger element. The object to be sealed is placed on the heating device and, as the cover closes the base, the safety switch engages the trigger element to release safety breaker device and to allow the power provision device to power the heating device. The heat insulation element prevents heat from conducted to the base. With the dual protection from the safety breaker device and the heat insulation element, safety is enhanced and the power provision device may operate under high voltage.

A welding apparatus for a fibre reinforced resin based material comprises an elongate flexible heat conductive strip and an elongate heat sink extending around at least a portion of the perimeter of the conductive strip.

A method and apparatus for sealing a plastic enclosure is provided. The apparatus includes a handle including elements pivotally coupled together at a first end. The apparatus also includes a pair of spaced apart heating elements positioned along an inner surface of an element and connected to a power source where a longitudinal axis of the heating elements is oriented parallel with a longitudinal axis of the element. Plastic material including first and second plastic layers is positioned at an interface between the second elements. Upon pivoting the first elements from an open position to a closed position the heating elements increase a temperature at the interface to melt the plastic material and form a pair of spaced apart seals between the first and second plastic layers.

A method for producing a tube skirt for a flexible tube, said tube skirt being manufactured from a flat strip 1 comprising a decorative film 15 superimposed on a primary film 16, said primary film 16 comprising a sealable inner layer 14 at the lower surface 20 of the strip 1 as well as two stabilizing layers 11, 13, said decorative film 15 comprising a sealable outer layer 7 at the upper surface 19 of the strip 1, and a decorative layer 8, 9. This method comprises the following steps: winding the flat strip 1 into the form of a sleeve to shape the tube skirt; superimposing a first side border 2 of the strip 1 on a second side border 2 of the strip 1 to form an overlapping area 3, the sealable inner layer 14 of the primary film 16 of the first side border 2 overlapping the sealable outer layer 7 of the decorative film 15 of the second side border 2; applying a heating temperature T2 to the inside of the tube skirt at the inner face 22 of the overlapping area 3 to produce the side weld of the tube skirt; simultaneously with the application of the heating temperature T2, applying compression between the outer 21 and inner 22 faces of the overlapping area 3 so as to finalize the side weld of the tube skirt.

A portable conveyor belt splicing apparatus is provided that includes an upper press assembly and a lower press assembly which include, respectively, upper and lower platen assemblies. The upper and lower press assemblies may each include a forced air cooling system for rapidly cooling platens of the platen assemblies. The upper and lower press assemblies may include insulating assemblies with resilient members that support the upper and lower press assemblies. The resilient members provide structural support and insulate the platens from the frame which reduces the power required to heat the platens. In one form, the apparatus includes a power supply circuit that can alternate between providing power to upper and lower heaters in response to the apparatus being connected to different types of standard power supplies. Further, the power supply circuit permits the use of a single recipe for a particular belt irrespective of the type of power supply.

There is provided an apparatus 1 that includes a pair of molds 10a and 10b that press together, heat, and weld an overlapping part of a plurality of film-like members, a pair of heater blocks 20a and 20b that respectively support the pair of molds; a plurality of first support blocks 37 that are connected via a plurality of rod-like members 50, which midway include parts that restrict transmission of heat, to one heater block 20a; a plurality of second support blocks 38 that are connected via the plurality of rod-like members to the other heater block 20b; and a driving mechanism 60 that changes, via the support blocks, a gap between the pair of molds to press together the film-like members. The plurality of first support blocks include at least one movable support block 39 including a mechanism 35 that moves in a first direction relative to the driving mechanism corresponding to thermal deformation in the first direction of the heater block to be supported, and the plurality of second support blocks include at least one movable support block 39.

A molding apparatus for a loop structure includes a molding die within which both ends of an elongated structure are located in such a manner that the ends are in contact with each other, the elongated structure being formed of a rubber to which a peroxide cross-linking agent is added; a liftable housing including a lower part having an opening, the housing defining a containment space within which the molding die and the elongated structure are located when the housing is lowered; a degassing device configured to depressurize and degas the containment space; a heating device configured to heat the molding die in the containment space; a pressure device configured to pressurize the ends of the elongated structure with the use of the heated molding die in the containment space to proceed cross-linking reaction of the rubber, thereby bonding the ends of the elongated structure; and an elevating device configured to lift and lower the housing.

A heating and sealing head (1) for packaging machines (M.sub.1; M.sub.2; M.sub.3) of products in trays (V), comprising a fixed support group (2) provided with first actuation means (3) electrically connected to a pneumatic system (4) for delivering compressed air, and a mobile application group (5) mechanically coupled to the fixed support group (2) by means of first fixing means and comprising heating means (6) electrically connected to an electric current generator (7), preferably alternating, which activates the heating means (6) to produce heat useful for sealing a closing and packaging film to one or more trays for containing products when the trays themselves are arranged under the heating and sealing head (1) in a packaging machine (M.sub.1; M.sub.2; M.sub.3). In particular, the heating means (6) comprise an electromagnetic inductor body (8) which produces the heat due to the effect of the parasitic electric currents induced by a magnetic field generated by the electromagnetic inductor body (8) when crossed or affected by the electric current.
