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 method for transversally sealing a packaging material tube, comprises placing a transversal sealing section of the tube between a sonotrode and an anvil. The transversal sealing section comprises a first two-layer sub-section, a three-layer sub-section and a second two-layer sub-section, transmitting ultrasonic acoustic vibrations, having a frequency and an amplitude, from the sonotrode into the transversal sealing section, thereby melting the plastic foil in the transversal sealing section, and pressing the tube together between the sonotrode and the anvil to bond the plastic foil such that transversal sealing is formed. The anvil has a ridge comprising various sub-sections for receiving various ones of the sub-sections of the tube, wherein the ridge has equal height in at least some of the sub-sections. The frequency, amplitude, pressure and paperboard properties are chosen to achieve equal temperature in the first two-layer sub-section, the three-layer sub-section and the second two-layer sub-section.

A pressure element for a sealing device includes a sealing member and a countersealing member facing one another and configured to be pressed against one another to seal therebetween a tube of packaging material adapted to be filled with a pourable product. The pressure element comprises a fitting portion configured to be fitted to the countersealing member and a contact portion defining a contact surface facing, in use, the sealing member and configured to interact with a sealing element of the sealing member to press and seal the tube therebetween. The pressure element comprises at least one engagement element configured to cooperate with a complementary engagement element carried by the countersealing member to guide the pressure element according to a predetermined orientation during fitting of the pressure element to the countersealing member.

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.

An apparatus for manufacturing a secondary battery includes: a recess induction part configured to allow a folding part folded in a battery case of a secondary battery to be recessed inward so as to provide a recess part when the battery case of the secondary battery is folded; a first guide, of which one side of one end is recessed to define a concave space, wherein, when the battery case of the secondary battery is folded, the one end is configured to be inserted into the battery case to push the folding part to an outside so that the recess induction part is configured to be inserted into the concave space; and a second guide configured to hold a sealing part of the battery case so as to fix the battery case.

A method of providing covers over at least a portion of a roof of a storm damaged built structure that includes the steps of: applying a sheet of heat shrinkable film over the portion of the roof, the sheet having a leading edge and a trailing edge and being a film of low density polyethylene including shrinking resins; wrapping portions of the leading edge around a first batten and attaching the first batten to the underside of a first eave or to the facia of the built structure; wrapping portions of the trailing edge around a second batten and attaching the second batten to the underside of a second eave or to the facia of the built structure at a location different than the first batten; and heating the sheet of heat shrinkable film to bring the film into conformity with the portion of the roof, wherein the heating step shrinks the sheet of film tight against the built structure to cover over the portion of the roof.

A system and method for controlling the speed of both a continuous web and a bonding apparatus is provided in order to effectuate stronger bonds in the web. The bonding system includes a velocity changing device for increasing and decreasing a velocity of the web in a machine direction, an anvil and a corresponding ultrasonic horn that interact to form ultrasonic bonds on the web, and an anvil actuator configured to control a movement of the anvil. A control system is also included in the bonding system for controlling operation of the anvil actuator the velocity changing device, with the control system programmed to decrease a moving velocity of the web from a feed velocity to a bonding velocity as the web passes between the anvil and the ultrasonic horn and control movement of the anvil to synchronize the movement of the anvil with the moving velocity of the web.
