The present invention relates to a sealing device, and more particularly, to a sealing device in which a temperature of a sealing surface of the sealing device is constantly maintained has an appropriate solvent is continuously heated using a phase change, thereby manufacturing a pouch sealing part having excellent quality in a product of a pouch type secondary battery.

The sealing device according to the present invention includes a sealing body provided with a sealing surface, which is configured to seal a sealing target object, on one surface thereof, a solvent that is in contact with the other surface of the sealing body to supply heat to the sealing body, and a heat source configured to heat the solvent so that at least a portion of the solvent is phase-changed into a gas.

A device for welding the bottom flange of a stiffener on the side of a skin. The stiffener and the skin are made of a composite comprising a thermoplastic polymer matrix. The device comprises a punch, an anvil and a press to make a clamping between the punch and the anvil. The punch comprises a part forming a pressure table with a cross-section width less than or equal to the width of the stiffener bottom flange and a heating element with width less than the width of the pressure table. The anvil comprises a cooling component and has a cross-section width smaller than the width of the skin. A method for implementing the device.

A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a single sealing zone, and a weakening zone disposed within the single sealing zone. The single sealing zone may be a heated perforator, includes a heating wire. The heating wire may be an NiCr wire stitched into the heater, and be disposed on a cap or on the seal bar. The weakening zone may create a line of weakness that is uniform or varies in intensity. The sealing zone may include temperature zones, cartridge heaters, cooling air, or heated air, or a source of ultrasonic, microwave or radiative energy.

An applicator mitt assembly system comprises an applicator mitt tooling including: a tooling body having a mitt-perimeter cutter and weld bead thereon which are shaped to a perimeter of an applicator mitt to be cut; a heating element associated with the tooling body, the heating element being shaped so as to match or substantially match a shape of the weld bead so as to create a perimeter weld for the applicator mitt when engaged with the tooling body; and an ejector platen which is actuatable relative to the tooling body to eject a cut and welded mitt away from the tooling body. The system can further comprise a conveyor device adapted to feed uncut and unwelded mitt material towards the applicator mitt tooling and a tooling actuator adapted to actuate the applicator mitt tooling relative to the conveyor device.

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.

Cool-down time is menimized by the use of a cooler having integral fins of high surface area, and the use of high-efficiency fans. Heat-up time is minimized by the low mass of the cooler, and the prevention of transmission of heat to the housing.

A pouch machine vertical sealer capable of fusing a pouch film web to form a plurality of spaced vertical seals along a length of the film web to form pouches. The pouch machine vertical sealer includes a sealer wheel rotatable about a vertical axis of rotation and defines a film web path about a periphery of the sealer wheel. The vertical sealer further includes a plurality of vertical sealer land assemblies spaced apart about the periphery of the sealer wheel. Each vertical sealer land assembly includes an impulse heater such that contact between the film web and each impulse heater of the plurality of vertical sealer land assemblies forms the spaced apart vertical seals along the length of the film web.

The device for welding thermoplastic parts includes a matrix for positioning the parts to be assembled, the matrix including an amagnetic insulating insert that defines joining zones in which the welds must be produced, a bladder defining a sealed volume and means for producing a partial vacuum in the sealed volume, and means for moving a magnetic induction head to near the joining zones and without making contact with the bladder. The welding process includes positioning at least one first part, then of placing metal inserts on areas of the first part corresponding to the joining zones that must be welded, and then positioning at least one second part. A bladder is put in place covering the parts and a partial vacuum is created in the volume defined by the bladder. The magnetic induction head is moved to produce the weld bead without contact while the partial vacuum is maintained.

A synthetic resin-made welding joint that has a pipe end portion into which an end portion of a synthetic resin-made tube is to be fitted and inserted, and that is configured so that the pipe end portion and the tube end portion which is fitted and inserted thereinto are enabled to be welded together by heating of heating means which externally surrounds the pipe end portion, therefore, a synthetic resin-made holder which is fitted and attached onto the pipe end portion is disposed, and a flange for ensuring a radial expansion gap with respect to the heating means is integrally formed in the holder.
