A method of joining overlapping thermoplastic geomembrane components in which a first thermoplastic geomembrane component and a second thermoplastic geomembrane component are positioned in overlapping relationship between a pair of complementary molding surfaces, with one or more of the complementary molding surfaces being defined by an electrically conductive metal susceptor. Heat is generated in the metal susceptor and transferred by thermal conduction from the metal susceptor to overlapping portions of the first and second thermoplastic geomembrane components to locally melt and coalesce a portion or more of the thermoplastic material of the first thermoplastic geomembrane component and a portion or more of the thermoplastic material of the second thermoplastic geomembrane component. The molten thermoplastic material of the first and second thermoplastic geomembrane components forms a zone of coalesced thermoplastic material that, upon cooling, forms a solid weld joint.

A material welder for welding at least two portions of a weldable material together, including: a top bar assembly and a bottom bar assembly, a portion of the top bar assembly directly above a portion of the bottom bar assembly, the top bar assembly including a first and second heating element substantially in the same plane and the bottom bar assembly including a first and second heating element substantially in the same plane, at least one heating device adapted to selectively heat the first heating elements and/or second heating elements, an actuator device adapted to move the top bar assembly towards the bottom bar assembly and/or the bottom bar assembly towards the top bar assembly, such that the first heating element of the top bar assembly aligns with the first heating element of the bottom bar assembly and the second heating element of the top bar assembly aligns with the second heating element of the bottom bar assembly; a contact surface of the top bar assembly and a contact surface of the bottom bar assembly adapted to contact the material during a welding process.

An imaging window of an imaging catheter includes a first imaging window section and a second imaging window section. The first imaging window section has a finite length and is formed from a first material having a flexural modulus. The second imaging window section has a finite length and is formed from a second material having a flexural modulus. The flexural modulus of the first material is different than the flexural modulus of the second material.

A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have connected thereto, a source of power that is an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire ay be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones ma include temperature zones, cartridge heaters, cooling air, or hated air, or a source of ultrasonic, microwave or radiative energy.

Structure for reducing sloshing noises, said structure being provided for disposal in a liquids container for a motor vehicle, having a random arrangement of mutually interlinked threads, wherein a plurality of the threads at least in portions are connected in a materially integral manner to at least one or a plurality of further threads of the structure, wherein the structure has at least one side in the region of which a planar cover of the random arrangement of mutually interlinked threads is provided at least in portions.

A system and method for forming a seam between at least first and possibly second pieces of material used to form an inflatable product utilizes at least a first and potentially a second seam forming members that are attached to an inside wall of a piece of product material that comprises the inflatable product proximate each end. The inflatable product is comprised of one or more pieces of product material and one or more seam forming members located at any location where a seam is necessary. A first portion of the seam forming member attaches to a first edge of a first piece of product material and a second portion of the seam forming member attaches proximate a second edge of the first piece of product material. The seal forming can be accomplished by radio frequency, ultrasonic, heat or other types of welding, and adhesive or chemical based bonding.

Disclosed is a tire building apparatus and a method for joining or cutting tire components. The tire building apparatus includes a rocking member that is movable in a rocking plane in a rocking motion along a rocking line, a translation guide extending parallel to the rocking line and a carriage that is displaceable along the translation guide, wherein the rocking member has a convex edge that defines a minor arc of a circle and extends up to a rotation center, wherein the rocking member is supported by the carriage at the rotation center and is angularly displaceable with respect to the carriage about a rotation axis extending through the rotation center.

The present invention is directed to a packaging material free from aluminium in the form of a continuous foil or film, comprising a layer of microfibrillated cellulose (MFC), wherein the layer comprising MFC has been laminated or coated on at least one side with a heat-sealable material. The MFC layer contains at least 60% by weight of microfibrillated cellulose. The present invention is also directed to a method for induction sealing, wherein a packaging material to be heat-sealed by induction is placed against an induction heating surface.

A container for packaging a pre-portioned amount of liquid or dry product is provided that includes a one-piece outer casing defining an interior reservoir. The outer casing has a cylindrical shell that is closed at one end by a rounded tip and open at the opposing end with an open circular outer edge/rim defining a mouth. To fill the container, the product is introduced through the mouth into the interior reservoir; then opposing edges of the rim are compressed together and sealed with heat to create an elongated seal having two opposing ends. Multiple types of elongated seals are provided. In one aspect the outer casing is formed unitarily of a plastic resin. To open the container, the consumer squeezes the two opposing seal ends/termini toward each other; this deforms the elongated seal and causes the seal to snap open, which allows access to the product.
