A bonder and a method for bonding corrugated sidewalls to a thermoplastic belt at a splice joint. Two heating jaw assemblies with complementary and confronting corrugated vertical faces clamp a thermoplastic belt to a base of the bonder with a corrugated sidewall section separated from the belt across a splice joint received in a corrugated slot formed between the confronting vertical faces. Corrugated bonding strips at the bottoms of the corrugated vertical faces apply heat to melt the bottom of the sidewall section on opposite sides to bond the corrugated sidewall section to the base.

A protrusion on a first member made of synthetic resin wherein a laser beam is applied to a side surface of the protrusion in a state in which a top surface of the protrusion of the first member is abutted against a second member made of synthetic resin, so as to melt at least the entire top surface of the protrusion and melt a portion of the second member in contact with the protrusion by heat of the melted top surface of the protrusion, followed by solidification of the melted portions, whereby the first member and the second member are welded together.

There is described a packaging assembly configured to form and seal a plurality of packs for containing a pourable food product starting from a tube of packaging material; the packaging assembly comprises a pair of tracks and at least a pair of moving elements, which are cyclically movable along the tracks, respectively; each moving element comprises one forming unit configured to cooperate with the tube so as to surround a portion of the tube destined to form a main portion of one respective pack; and one sealing unit configured to cooperate with the tube to sequentially seal the tube at predetermined consecutive cross sections, each pair of consecutive cross sections forming opposite sealing bands of one respective pack; each forming unit is mounted onto the respective moving element in a linearly movable manner towards and away from the sealing unit mounted onto the same moving element.

A method and installation for joining a cover layer to an object in a continuous process. Joining is effected with the aid of a joining material having thermoplastic properties, wherein the joining material is arranged between the cover layer and the object and is liquefied using ultrasonic vibration energy. Before application of the ultrasonic vibration energy, the joining material is preheated in a contactless manner with the aid of electromagnetic induction in the region of the glass transition temperature of the joining material or above this glass transition temperature. The object is in particular a chip board and the cover layer an edge strip to be joined to an edge of the chip board.

A portable assembly for securing a plastic fitting to a plastic pipe by employing fusion or thermal sealing is disclosed. The assembly is secured to the outer circumference of a plastic pipe at a desired location. The assembly can be secured at any longitudinal and lateral position along a plastic pipe. A heater heats both the pipe and the fitting to the point where they begin to melt. The heater is then removed and the fitting is pressed onto the surface of the pipe, thus fusing the fitting to the pipe. After cooling, the assembly is removed and the surface of the pipe within the interior of the fitting is drilled or removed. This now enables fluid within the pipe to be sent to the fitting and onto distribution lines which are connected to the fitting.

A process for packaging a product arranged on a support comprising unrolling a film, moving the film to a packaging assembly defining at its inside a packaging chamber, progressively moving a number of supports inside the packaging chamber of the packaging assembly, closing the packaging chamber with the film sheets held above the respective support, optionally causing one or both of: a gas withdrawal from the hermetically closed packaging chamber and gas injection of a gas mixture of controlled composition, heat sealing the film to said support, wherein the heat sealing uses one or more heaters having heating surfaces which are heated for discrete and short time periods only. An apparatus for performing the above process is also disclosed.

A system for establishing an anchorage or augmentation in hard tissue with the aid of a material having thermoplastic properties, which is brought to the site of the anchorage or reinforcement in a solid state, is liquefied in situ, and, in a liquefied state, is displaced to contact the object. The system includes a housing with a proximal housing part and mounted therein, a transmitting piece possibly coupled to an energy source and a driver spring, a distal housing part releasably coupled to the proximal housing part, a permeable sleeve couplable to the distal housing part, and a thermoplastic element positionable in the permeable sleeve. The two housing parts, the transmitting piece, the driver spring and the permeable sleeve form a closed load frame in which the thermoplastic element is compressed between the transmitting piece and the permeable sleeve.

This disclosure relates to a machine (1) for sealing containers (91) using a film (95). The machine (1) comprises a first jaw member (21), comprising a plurality of seats (20) for respective containers (91) to be sealed, and a second jaw member (22), facing towards the seats (20) of the first jaw member (21). The first jaw member (21) and the second jaw member (22) are movable one relative to the other between a first condition, in which the two jaw members (21, 22) are separated from each other by an interspace (23) suitable for receiving a film (95), and a second condition, in which the two jaw members (21, 22) are clamped together and, in use, press the film (95) against the containers (91) in the seats (20). The seats (20) are side by side one after another along a longitudinal line (200) extending between a first side (231) and a second side (232) of the interspace (23). The machine also comprises a film feeding device (3) facing towards the first side (231) of the interspace (23), and a positioning apparatus for positioning the film (95) in the interspace (23). The film (95) positioning apparatus comprises a first gripping device (4), which is positioned at the second side (232) of the interspace (23), and a second gripping device (5), that is movable parallel to the longitudinal line (200) between a first position close to the film feeding device (3) and a second position close to the first gripping device (4). The second gripping device (5) in the first position is capable of gripping one edge of the film (95) which projects from the film feeding device (3) and is capable of pulling the gripped film (95) with a movement towards the second position, thereby positioning the film (95) in the interspace (23) at said plurality of seats (20). The first gripping device (4) is capable of gripping the edge of the film (95) positioned by the second gripping device (5). This disclosure relates also to a method for sealing a plurality of containers (91).

When a cylinder portion of an innerliner is positioned inside a mouthpiece and when an upper mold and a lower mold are brought together, a projection portion is provided on an outer circumferential member of the lower mold that closes a gap between a section of an upper mold side positioning outer circumferential surface following on from an inner circumferential end of an outer abutting surface and a portion of the innerliner where an inner circumferential surface abuts. As a result, the portion of the innerliner that is thermally deformed is prevented from being displaced radially inward of the mouthpiece along a first annular surface.
