A packaging container for holding contents such as fresh food. The container comprises a tray having a flange, a pre-formed scaling ring and a flexible film for sealing in the contents of the tray. The sealing ring is made from fiber, filament or tape (“FFT”) that is shaped into a shape that matches the shape of the tray flange. The sealing ring is adhered to the tray flange by heat welding or other means and the flexible film is adhered to the sealing ring.

A method for joining at least two joining partners includes performing a plurality of ultrasonic joining operations in direct succession, wherein performing an individual ultrasonic joining operation includes, with a second joining tool, applying pressure to a second joining partner arranged adjacent to a first joining partner, thereby pressing the second joining partner against the first joining partner, and, with the second joining tool, applying high-frequency ultrasonic vibrations to the joining partners. The method further includes, during at least one intermediate time interval between two directly successive ultrasonic joining operations, at least one of actively cooling and heating the second joining tool.

Disclosed is a method of manufacturing yoga outer socks with a silicone band attached thereto by forming a temporary connection part using ultrasonic waves without a seam between an outer sock upper and a sole part, adhering hot melt to the temporary connection part via heat fusion, and then fusing a silicone band onto hot melt to prevent slipping of the heel. Accordingly, the yoga outer socks are manufactured by forming a temporary connection part with ultrasonic waves without a seam and then adhering hot melt to the temporary connection part via heat fusion to simplify manufacturing processes and to achieve excellent productivity.

A method for adhering a label, lettering, ink, a tattoo, sketch, design or color (“indicia”) to a substrate comprising the steps of: providing an indicia-bearing backing paper; moistening the indicia-bearing backing paper to form a moistened indicia-bearing layer; providing an adhesive layer between the moistened indicia-bearing layer and the substrate; placing the moistened indicia-bearing layer on the adhesive layer; allowing the indicia to become separated from the backing paper, leaving the indicia upon the substrate; and drying on the substrate.

A system for applying a fastening material to a substrate is provided. The system may include a first material source including the substrate. The substrate may define a first length extending from a first edge to a second edge and the first material source may feed the substrate in a first direction transverse to the first length. The system may additionally include a second material source including the fastening material. The fastening material may define a second length extending from a third edge to a fourth edge, whereby the second length is substantially equal to the first length and the second material source feeds the fastening material in a second direction transverse to the second length. The system may also include an applicator system that secures the fastening material to the substrate.

A device and a method for applying cover sheets to cross-bottoms of tubular sections made of a plastic material. The device includes conveyor devices for transporting the tubular sections and for depositing the cover sheets on the cross-bottoms in a deposit area. The device includes a hot gas device with a gas heater and a nozzle connected to the gas heater and oriented toward the deposit area for the cover sheets so when gas is supplied to the gas heater, the gas flows along a flow path from the gas supply through the gas heater and the nozzle into the deposit area. The hot gas device has a hot gas reservoir with an internal volume for the temporary storage of hot gas, the flow path running through the hot gas reservoir. A gas mass flow ({dot over (m)}1, {dot over (m)}2, {dot over (m)}ges) of gas supplied to the gas heater is adjustable by a control.

A method for connecting components having a fibre-reinforced thermoplastic plastic includes provision of a first component with a first joining surface, provision of a second component with a second joining surface, flush placement of the first joining surface against the second joining surface in order to form a connection joint, placement of a friction stir welding tool against the connection joint, or a surface directly adjacent thereto, of at least one of the components, softening of the first component and the second component, in each case in a region adjacent to the connection joint, by rotation of the tool, such that the thermoplastic plastic of the two components locally fuses, and movement of the tool along the connection joint for the purposes of connecting the two components by formation of a fusion seam, wherein portions of reinforcement fibres are stirred in to increase the strength of the fusion seam.

A sealing device for sealing edges of composite fiber components includes a strip feeder to apply a thermoplastic semifinished product to a cut edge of a composite fiber component, and an ultrasonic welding apparatus to thermoplastically or integrally join the thermoplastic semifinished product to the cut edge of the composite fiber component by ultrasonic welding.

A yarn or thread may include a plurality of substantially aligned filaments, with at least ninety-five percent of a material of the filaments being a thermoplastic polymer material. Various woven textiles and knitted textiles may be formed from the yarn or thread. The woven textiles or knitted textiles may be thermal bonded to other elements to form seams. A strand that is at least partially formed from a thermoplastic polymer material may extend through the seam, and the strand may be thermal bonded at the seam. The woven textiles or knitted textiles may be shaped or molded, incorporated into products, and recycled to form other products.

An apparatus for applying the film to the substrate includes a bed having a substrate placement surface and a selectively positionable tack bar, a roller support moveable over the span of the bed, and including the location of the positioning bar, and a roller rotatably supported to the positioning bar and moveable over the bed in response to movement of the roller support with respect to the bed. In another aspect, the tack bar is of the same thickness, or slightly less thick, as the substrate onto which the film is to be applied, such that a portion of the film to be applied can be secured thereto and not on the substrate before the backing is removed from additional portions of the film, such that the tack bar supports an end of the film in substantially the plane of, or slightly below the plane of, the substrate.
