A disclosed apparatus for forming a sealing portion for folding a secondary battery pouch includes: first and second pressing bars disposed to face each other with a sealing portion for folding therebetween to apply pressure for flattening the sealing portion for folding that is defined by the edge of a secondary battery pouch for sealing an electrode assembly accommodated therein; first and second pressing surfaces provided at the first and second pressing bars, respectively, and disposed to face the sealing portion for folding; and a forming protrusion formed on the first pressing surface and configured to form a folding guide line on the sealing portion for folding by pressure applied by the first and second pressing bars.

A disclosed heater for a sealing process of a secondary battery includes: a sealing bar heating and pressing a pouch foil to be sealed; a plurality of sub-heating unit longitudinally disposed inside the sealing bar to respectively independently supply heat to a plurality of sections separated in the longitudinal direction of the sealing bar; temperature sensing units disposed inside the sealing bar and sensing temperature at positions on the surfaces being in contact with the pouch foil; and a control unit controlling heating temperature of the plurality of sub-heating units on the basis of the temperature sensed by the temperature sensing units.

A method of induction welding a first thermoplastic composite (TPC) to a second thermoplastic composite (TPC) using an induction coil includes forming a weld interface area between the first TPC and the second TPC, cooling the first TPC with a cooling apparatus before heating by the induction coil, and inductively heating the weld interface area with the induction coil after cooling the first TPC.

A system (10) for butt-joining two or more rubber strips (B1, B2) selected in accordance with a predetermined rubber mixture recipe in order to feed at least one extruder with a complex strip of rubber material (B12) made from the butt joined rubber strips is disclosed. The system includes at least one conveyor that transports the rubber strips from an inlet (12) of the system to an outlet (14) of the butt-joining system; a frame (18) that operationally supports the conveyor to allow the continuous transport of the rubber strips and also to allow the simultaneous butt-joining of the rubber strips fed to the system; and a roller system (20) that butt-joins the rubber strips without penetration. The invention also relates to a process for butt-joining rubber strips that is performed by the system.

A method of induction welding a first thermoplastic composite (TPC) to a second thermoplastic composite (TPC) includes inductively heating a weld interface area between the first TPC and the second TPC, and cooling a surface of the first TPC opposite the weld interface area while inductively heating the weld interface area.

A heat sink for use in induction welding includes a number of tiles, wherein the tiles are electrically non-conductive and have a thermal diffusivity of greater than about 25 mm2/sec. A joint flexibly joins the tiles together.

Applicators for applying a masking material to a target surface, the applicators include a body, an applicator system attached to the body and configured to apply the masking material to the target surface with a substantially straight edge as the body is translated in an application direction, a dispenser system attached to the body, the dispenser system being configured to support a supply of the masking material and to dispense the masking material to the applicator system, and a guide member attached to the body proximate the applicator system in a trailing position and configured to press the masking material to the target surface after the applicator system applies the masking material to the target surface.

A method of induction welding a first thermoplastic composite (TPC) to a second thermoplastic composite (TPC) using an induction coil includes forming a weld interface area between the first TPC and the second TPC, cooling the first TPC with a cooling apparatus before heating by the induction coil, and inductively heating the weld interface area with the induction coil after cooling the first TPC.

A heat sink for use in induction welding includes a flexible backing and a number of tiles disposed on the flexible backing in a single layer, wherein the tiles are electrically non-conductive and thermally conductive.

A heat sink for use in induction welding includes a number of tiles, where the tiles are electrically non-conductive and thermally conductive, a joint flexibly joining the tiles together, and a fluid path formed through the heat sink for communicating a coolant therethrough.
