An ultrasonic sealing unit is equipped with a converter, a horn, a fixing member, and a retaining member. The converter generates ultrasonic waves from an electrical signal. The horn vibrates because of the ultrasonic waves generated by the converter. The fixing member is a member for fixing the ultrasonic sealing unit. The retaining member is a member for retaining the ultrasonic sealing unit in a position different from the position where the ultrasonic sealing unit is fixed by the fixing member. The ultrasonic sealing unit may reduce vibration transmitted to the surroundings.

Disclosed is a welding machine for synthetic resins. The welding machine for synthetic resins performs welding of fabrics using ultrasonic waves and through preheating sufficient not to burn off a coating solution on the surfaces of the fabrics using hot air so as to achieve rapid and firm welding due to concentrated molecular decomposition and melting on the bonding surface between the fabrics, allows both an ultrasonic horn and a welding wheel to be rotated vertically so as to achieve rapid and stable entry of the fabrics and welding of the fabrics while preventing the fabrics from slipping, and achieves stable welding of various fabrics through adjustment of pressing force of the welding wheel depending on the thickness or the material of the fabrics, etc.

For sealing a test space in a workpiece having at least one open end face having a flat surface with one or more indentations in the workpiece, a sealing mat having a planar basic body and one or more arcuate sealing elements can be used. The sealing mat is placed onto the surface of the open workpiece end face such that the arcuate sealing elements of the sealing mat protrude into the indentations in the workpiece to then press the basic body of the sealing mat against the surface of the open workpiece end face with a pressing force in a direction perpendicular to the flat surface and press the arcuate sealing elements into the indentations with pressing forces in several directions radial to the arcuate shape of the sealing elements.

A welding assembly is disclosed. The welding assembly includes a plurality of separately controllable actuators (e.g., pneumatic, having an axially movable ram) to press a corresponding portion of a first workpiece (e.g., a discrete flange of a first stiffener) against a second workpiece (e.g., an outer skin) for welding operations (e.g., via induction welding).

The present invention relates to a sealing device for a secondary battery. The sealing device is configured to seal a battery case accommodating an electrode assembly therein to manufacture the secondary battery, the sealing device including a sealing block configured to press a sealing portion of the battery case, a flatness adjusting part configured to adjust a flatness of a pressing surface of the sealing block, and a heater part configured to transfer heat to the sealing block to thermally fuse the sealing portion of the battery case when the sealing portion is pressed by the sealing block.

A bonding apparatus includes adhesive sheet that includes a central adhesive portion adhered to a central portion of a first substrate and a bendable adhesive portion that surrounds the central adhesive portion in a plan view and that is adhered to an edge portion of the first substrate that extends from the central portion, a molding member that includes a top surface that overlaps the central portion and a side surface bent from the top surface and that has a curved shape and that supports the adhesive sheet through the top surface, a magnet member disposed on a first display surface of a second substrate that covers the central portion of the first substrate, and pressing balls disposed in the molding member. The pressing balls press fife central adhesive portion and the bendable adhesive portion by forming attractive force with magnet member.

Composite fabrication system and associated methods. In one embodiment, a composite fabrication system comprises a molding tool that includes a forming surface at least partially disposed within a constrained space, and a foamable material that expands inside of the constrained space to form an expanded material that presses a layup of one or more composite layers against the molding tool. The composite fabrication system further comprises a curing device configured to cure the layup to form a composite part, and a cutting wire embedded in the constrained space that is heated and configured to cut the expanded material into pieces that are removable from the constrained space.

The pressure jaw assembly (1) comprises a pressure jaw frame (10), a pressure element (20) arranged to be moved relative the pressure jaw frame (10), a compressing means (40) arranged at least partly between the pressure jaw frame (10) and the pressure element (20). The compressing means (40) is arranged to influence the relative movement between the pressure element (20) and the pressure jaw frame (10). The pressure jaw assembly (1) further comprises a guide (50, 52) for guiding the pressure element (20). The guide (50, 52) is connected to the pressure jaw frame (10), and the guide (50, 52) is arranged externally of the pressure element (20).

The invention relates to a stamp-sealing unit comprising a punch designed as a sonotrode (8), and a die (5), said die (5) having an opening (15) and the punch being able to be moved in and out of the opening (15) in the stamping direction. The invention also relates to an ultrasonic processing device for stamping stamped parts out of a stamping material (2) and for sealing the stamped parts to unprocessed products (21).
