A welding process of an inflatable product is provided that includes using isolating members between first and second portions of weldable tensioning members to resist the first and second portions of the weldable tensioning structures being welded together during welding of the first portions to a first sheet of weldable material and welding of the second portions to a second sheet of weldable material.

A sealing structure of an air-pocket bag machine includes at least one heating plate, a sealing roller that is rotatably mounted to and positioned against the heating plate for conducting a heating and pressing operation on and thus sealing at least one air-pocket bag through a heating operation of the heating plate, and at least one driving roller that is coaxially and rotatably coupled to the sealing roller for driving and advancing the air-pocket bag. With such an arrangement, when the air-pocket bag machine is activated, the air-pocket bag is driven by being in contact engagement with the driving roller and thus is moved to fast, stably, and continuously pass under the sealing roller. Due to the sealing roller and the driving roller being rotatably coupled in a coaxial manner, the advancing speed of the air-pocket bag is consistent with the rotational speed of the sealing roller.

A carpet seaming iron comprising a heater plate arranged for contact with at least one of carpet seaming tape and carpet, and at least one electrical heating element in thermal communication with a heater plate. The carpet seaming iron may be cordless and comprise a battery in the form of a rechargeable battery.

Multi-layered articles or products comprising layers of filled polymer compositions, methods of making and applications or uses thereof.

A method of forming shaped articles by welding.

An example system comprises a water-soluble unit dose article comprising a fibrous non-woven sheet shaped to form a sealed internal compartment and a granular laundry detergent comprised within the internal compartment. The sheet comprises fibres which comprise polyvinyl alcohol polymer. The granular laundry detergent comprises perfume particles. The system also comprises sealing jaws, whereby at least one of the sealing jaws is a heated sealing jaw. A top seal of the internal compartment is sandwiched between the jaws. A first of said jaws comprises a protruding portion along a longitudinal direction of the seal. The protruding portion has a base along a direction perpendicular to the longitudinal direction of the seal. The base has a dimension of more than 3 times and of less than 20 times a thickness of the water-soluble fibrous non-woven sheet.

A production line for PFCs with FMDs includes a conveyor system, a supply system, and an installation system. The conveyor system is operable to convey PFCs. The supply system includes a roller stage. The roller stage operable to feed FMDs. The installation system includes an installation tool. The installation tool includes a mandrel, a platen, a platen heater, and a platen actuator. The installation tool is configured to receive FMDs from the roller stage in part around the mandrel and in part around the platen, configured to insert into PFCs on the conveyor system, and operable to install FMDs thereto by the operation of the platen heater to heat the platen and the platen actuator to radially expand the platen.

An apparatus for folding a battery cell according to an embodiment of the present invention may fold a sealing part of a pouch-type battery cell. The apparatus for folding the battery cell includes a base on which an accommodation part of the battery cell is seated, a guide protruding upward from each of both sides of the base to wrap the accommodation part at both sides, a pressing member configured to press the sealing part so that the sealing part is folded toward an outer surface of the guide, a heating member configured to heat the sealing part when the pressing member presses the sealing part, and a cooling member configured to inject cold air to the folded sealing part.

An apparatus for roll forming thermoplastic composites comprises a plurality of thermoplastic composite material spools, a plurality of thermoplastic composite material rollers, a plurality of sheet metal spools, a plurality of welding rollers, an oven, a forming roller, a pair of pinch rollers. The thermoplastic composite material spools retain plies of thermoplastic composite material. The plies flow through the thermoplastic composite material rollers to form a layup. The sheet metal spools retain metal sheets. The metal sheets and the layup flow through the welding rollers to form a metal composite material laminate. The oven heats the metal composite material laminate. The forming roller imparts a curvature to the metal composite material laminate. The pinch rollers receive the metal composite material laminate from the forming roller, pull the metal composite material laminate, and output the metal composite material laminate in a heated and compressed state.
