The invention relates to an ultrasonic booster (1) for a sonotrode (30) for processing workpieces (W) with ultrasonic vibrations, having a booster body (10). Longitudinal vibrations (SL) are introduced into the booster body (10) on a sound introduction side (11) having a first end side (12). A conversion structure (15), by means of which transverse vibrations (ST) having a vibration component in a plane (E) perpendicular to the longitudinal axis (L) are generated from the longitudinal vibrations (SL), is located between the sound introduction side (11) and a coupling side (13) opposite the sound introduction side.

An adjustable sealing apparatus and corresponding method of use is disclosed. The sealing apparatus has a variable range of motion programmed to accommodate multiple types of sealing motion, including the reciprocal motion and rotary motion. The proposed design uses two sealing jaw units with each sealing jaw unit located on opposing sides of a continuous layered film. Each sealing jaw unit has a sealing jaw coupled to a distal end of extendable linkages. The sealing jaws are extendable to allow the sealing surfaces to engage one another at a plurality of sealing locations along a plurality of sealing paths. Moreover a control unit is communicatively coupled to each of the sealing jaw units and controls movement of the sealing jaw units to engage one another at one or more of the plurality of sealing locations which enables sealing of the film to produce bags.

The invention relates to a device for welding a connection region of a film to a connection part having an axial direction. In the case of conventional devices, there is the risk of steep workpiece edges causing uncontrolled weak spots in the film and in the weld seam. According to the invention, the film is extended in a controlled manner such that the film has a length reserve. The film is extended in such a way that the film has a deformation cross-section that runs out such that the deformation is not visible on the final product. In this connection, the invention further relates to a use of a film, to a method for welding, to a method for producing bags, to a system for producing bags, and to a bag.

A horn for an ultrasonic welding apparatus includes a body having an outer diameter surface and a convex welding tip having a first curved surface and a second curved surface. A peak curvature point is defined by the second curved surface. A base curvature point is defined at an intersection between the outer diameter surface and the first curved surface. An inner diameter is defined at an intersection between the first curved surface and the second curved surface.

A thermal transfer apparatus includes a fixture, a foil securing film, a film retainer, a foil transfer tool, and a carriage conveyor. The fixture retains a transfer object. The foil securing film is disposed above the fixture. The foil securing film allows light to pass therethrough. The foil securing film presses, from above, a thermal transfer foil on the transfer object so as to secure the thermal transfer foil onto the transfer object. The film retainer retains the foil securing film. The film retainer moves the foil securing film in an up-down direction relative to the fixture. The foil transfer tool presses the foil securing film and the thermal transfer foil on the transfer object. The foil transfer tool emits light to the foil securing film. The carriage conveyor moves the foil transfer tool relative to the fixture.

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.

Provided is a method of manufacturing a flexible display apparatus. The method includes: arranging a film over a window having a three-dimensional curved surface shape, the film being flexible; arranging a plurality of pressure balls over the film; and pressing the plurality of pressure balls towards the window by using a pressure plate such that the film is closely adhered onto the window according to the three-dimensional curved surface shape of the window.

A cover window manufacturing apparatus includes a plurality of fixed plates, a plurality of moving plates, a plurality of molds and a driver. The plurality of fixed plates is layered and spaced apart at a distance from each other. The plurality of moving plates is layered, spaced apart at a distance from each other and respectively disposed under the plurality of fixed plates. A plurality of connection members integrally connects the plurality of moving plates with each other. The plurality of molds is respectively provided on the plurality of moving plates, and inner spaces for molding the cover window are respectively defined in the plurality of molds. The driver is coupled to one of the plurality of moving plates, and is configured to move the plurality of moving plates towards the plurality of fixed plates such that the plurality of molds are pressed to the plurality of fixed plates.
