The present invention relates to a pouch-shaped battery case sealing apparatus capable of adjusting a direction in which an upper sealing block configured to press a laminate sheet applies pressure to the laminate sheet during a process of applying heat and pressure to an outer periphery of a battery case made of the laminate sheet to seal the outer periphery of the battery case when a pouch-shaped battery is manufactured and a pouch-shaped secondary battery sealing method using the same.

The present invention relates to a pouch-shaped battery sealing apparatus including a stopper capable of adjusting a thickness after sealing in a process of sealing the outer edge of a battery case made of a laminate sheet by applying heat and pressure thereto when a pouch-shaped battery is manufactured and a pouch-shaped battery sealing method using the same.

A cup sealing apparatus with a shaft, a heating element, an alignment plate, and a spring biasing the alignment plate into engagement with the alignment cone. The shaft extends has an alignment cone at an end thereof, the alignment cone having a modified cone taper surface centered about a longitudinal axis. The heating element includes a heating surface operable to adhere a seal to a cup presented to the heating surface. The alignment plate is spaced from the opposite axial surface, and has a profile corresponding with the taper surface so that the profile and the taper surface form a non-circular interface between the alignment cone and the alignment plate. With deflection of the spring, the alignment plate and the heating element are free to deviate from a prescribed orientation and out of coaxial alignment to match a cup axis of a cup presented to the heating surface.

The present invention provides a sealing process for a secondary battery of the present invention, which thermally fuses and seals a sealing portion that extends along an edge surface of a battery case, the sealing process comprising: an arrangement operation of disposing the sealing portion of the battery case between an anvil and a horn; a first region-fixing operation of pressing and fixing a first region of the sealing portion through the anvil and the horn; and a first region-primary sealing operation of applying an ultrasonic wave to the first region of the sealing portion through the horn at a set frequency and a set amplitude for a set time, thereby thermally fusing the first region of the sealing portion.

The present disclosure relates to methods by which a warped workpiece is reconfigured in a pre-determined manner to reduce a separation between the warped workpiece and a joining workpiece. The warped workpiece is reformed/reshaped, prior to joining, by softening material of the warped workpiece through application of a predetermined amount of energy at or near warping and using a directional force applied to a first surface of the warped workpiece, thus reducing a separation space at a joining interface of the warped workpiece and joining workpiece.

A stitchless highly oriented polypropylene fabric bulk bag of the type that can hold 500 to 5000 pounds (226.7 to 2268 kilograms) of bulk material includes a highly oriented polypropylene fabric top, body and bottom, with a heat fused joint providing an air tight connection between the top and body, and another air tight heat fused joint connecting the body and bottom. A fill spout and discharge tube may also be provided with an air tight heat fused joint connecting the fill spout to the top and another air tight heat fused joint connecting the discharge spout to the bottom. Heat sealing machinery include heat seal bar assemblies that can self-align during heat-sealing to apply even pressure to all areas being heat sealed. A heating element is of single piece construction and can include end coupler portions as part of the single piece construction. Carrier plates used in a heat-sealing assembly line guide parts placement, provide quality checks for parts placement, and tooling set-up for machinery.

A rotary welding device which includes a rotary part rotating about its axis of rotation, one or more supporting elements for supporting a continuous strip, specifically a strip of nappies, supported by the rotary part, and a plurality of welding units, mounted on the rotary part, for welding the continuous strip; each welding unit is configured to pass from a non-operating position to an operating position and vice versa; each welding unit includes a respective welding tip and a respective anvil element which is movable relative to the welding tip; each welding unit includes respective first movement means configured to drive the anvil element in rotation relative to the welding tip from an initial position, where the anvil element is angularly spaced from the welding tip, to a final position, where the surface of the welding tip and the surface of the anvil element are parallel and aligned with each other along the same axis, and vice versa.
