A sealing apparatus including a sealing tool that is movable between an inactive position and a sealing position. The sealing tool includes two actuating elements, each with a respective actuating surface that face each other. The actuating elements are configured to allow the passage of a packaging material therebetween and for transversely sealing the packaging material when the sealing tool is in the sealing position. The actuating surfaces are configured to cooperate with one another to perform the sealing. The actuating surfaces are also configured to cooperate with one another during the change in position of the sealing tool to the sealing position, and for transversely cutting the packaging material during the change in position.

A first thermoplastic component and a second thermoplastic component including a first joint portion and a second joint portion, respectively, are provided. A least a portion of a surface area of each of the first and second joint portions include a respective first and second mating surface. The first and second mating surfaces of the respective first and second joint portions are positioned in contact with one another. The first and second joint portions are fusion joined. Fusion joining the first and second joint portions forms a fused unitary portion of the first and second thermoplastic components.

A method of producing a golf ball applies ultrasonic welding on two half shells to form at least one intermediate layer, at least one cover layer, or at least one intermediate layer and at least one cover layer. The ultrasonic welding may include pressing the two half shells together, delivering a high power electrical signal to a welding stack, and converting the high power electrical signal at the welding stack to ultrasonic energy. The converting may include converting the high power electrical signal into a mechanical vibration, modifying an amplitude of the mechanical vibration to generate a modified mechanical vibration, and applying the modified mechanical vibration to an interface of the two half shells to weld them together ultrasonically. Aspects also relate to golf balls, or one or more layers thereof, made using ultrasonic welding.

The invention is a device for welding two overlapping film sections situated on one side of a goods stack. The device includes a welding bar with a welding surface oriented in the direction of the film sections to be welded. The spacing between the welding bar and the film sections is reducible. The welding surface is elastically deformable into a concave course and/or to a convex course between its two ends. At least one displacing device adjusts the course of the welding surface to a concave and/or to a convex course. The displacing device displaces welding bar. A control unit of the welding bar individually controllable, such that the curvature of the welding bar is adjustable to the contour of the side of the goods stack in the region of the film sections to be welded with one another for the subsequent welding of the overlapping film sections.

A method for manufacturing an air bag includes forming a bag portion surrounded by a welded portion extending in an annular shape by pressing at least one welding mold against two sheet materials arranged to be stacked from a stacking direction of the sheet materials. The welding mold is pressed against the sheet materials to form the welded portion including a welding bead portion protruding to an inside of the bag portion between the sheet materials. A pressing surface of the welding mold against the sheet materials is provided with a slope portion facing in the stacking direction of the sheet materials and in a direction of the inside of the bag portion at a position further on an outside of the bag portion than a position at which the welding bead portion is formed.

Systems and methods are presented herein for a method of attaching a strip to a housing. An internal support member is inserted into a collapsible housing, such that it is arranged along a longitudinal axis of an inner surface of the collapsible housing. An outer support member is arranged along an outer surface the collapsible housing opposite the internal support member. A strip is positioned along the outer surface using the outer support member and the internal support member. Then the strip is permanently welded to the outer surface using a welding element. Welding is performed by a welding element located in one (or both) of the internal support member or the outer support member.

A device and a method for manufacturing a rotor blade for a wind energy installation, wherein the rotor blade includes at least two rotor blade shells which are bonded together, includes a holding device arranged to hold a rotor blade shell such that at least one bonding surface on the rotor blade shell and/or on a web attached to the rotor blade shell is exposed. The bonding surface of the rotor blade shell can be bonded to a further rotor blade shell. The device further includes a robot arm arranged to apply adhesive to the at least one bonding surface, a carriage on which the robot arm is mounted, and a guide device mounted on the holding device. The carriage is mounted on the guide device so as to be movable. The guide device is arranged to guide the carriage and the robot arm along the holding device, in particular along the bonding surface.

A microfluidic cartridge, configured to facilitate processing and detection of nucleic acids, comprising: a top layer comprising a set of cartridge-aligning indentations, a set of sample port-reagent port pairs, a shared fluid port, a vent region, a heating region, and a set of detection chambers; an intermediate substrate, coupled to the top layer comprising a waste chamber; an elastomeric layer, partially situated on the intermediate substrate; and a set of fluidic pathways, each formed by at least a portion of the top layer and a portion of the elastomeric layer, wherein each fluidic pathway is fluidically coupled to a sample port-reagent port pair, the shared fluid port, and a detection chamber, comprises a turnabout portion passing through the heating region, and is configured to be occluded upon deformation of the elastomeric layer, to transfer a waste fluid to the waste chamber, and to pass through the vent region.

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.
