A method for manufacturing components includes joining a first edge of a thermoplastic-containing first component part and a second edge of a thermoplastic-containing second component part to one another without any overlap. The first and the second edge are interconnected by friction stir welding. Friction stir welding involves rubbing a rotating friction stir welding pin against at least one metal object.

An apparatus for packing articles, wherein the packing is formed by at least one web material, wherein typically a plurality of individual juxtaposed runs of web material and a number of more or less packed articles are conveyed on the runs, wherein the apparatus includes first mechanism which, during packing of articles, joins the web material continuously in its longitudinal direction, as well as other mechanisms for producing individual joints and for separation of the articles in a transverse direction of the web material, wherein the mentioned other mechanisms are arranged on moving means adapted to move in the same direction and at the same speed as the web material and the articles being packed, called the X-axis, and in a direction towards the web material and the articles arranged thereon, called the Y-axis.

A film pasting tool is used to paste one surface of a film on a member-to-be-pasted at a predetermined position. The tool comprises a flexible tabular body, a first adhesive part, a front surface thereof being adhesive, provided on one surface of the body, and a second adhesive part, a front surface thereof being adhesive, provided on a part of a region other than a region where the first adhesive part is provided out of one surface of the body. An other surface of the film is pastable on the front surface of the second adhesive part, and when the other surface of the film is pasted on the front surface of the second adhesive part, the front surface of the first adhesive part is exposed in such a manner that the front surface of the first adhesive part is pastable on the member-to-be-pasted.

A fin sealer and method to seal a radially outwardly directed fin of a tubular web structure by directing the fin through a nip between a first and a second fin sealing rollers while communicating heat to the fin through at least one of the fin sealing rollers is provided. The fin sealer is configured to maintain a nominal face-to-face relation between an outer annulus of the first fin sealing roller and an outer annulus of the second fin sealing roller with a flexible connection between a hub element of the second fin sealing roller with the outer annulus of the second fin sealing roller.

An applicator mitt assembly system comprises an applicator mitt tooling including: a tooling body having a mitt-perimeter cutter and weld bead thereon which are shaped to a perimeter of a mitt to be cut; a heating element associated with the tooling body which is shaped so as to substantially match a shape of the weld bead to create a perimeter weld for the mitt when engaged with the tooling body; and an ejector platen which is actuatable relative to the tooling body to eject a cut and welded mitt. A conveyor device is adapted to feed mitt material towards the tooling and a tooling actuator adapted to actuate the tooling relative to the conveyor device to allow the cutter to cut mitt material at the conveyor device. A discrete applicator mitt tooling, method of assembling an applicator mitt, and welded applicator mitt are also provided.

An applicator mitt assembly system comprises an applicator mitt tooling including: a tooling body having a mitt-perimeter cutter and weld bead thereon which are shaped to a perimeter of an applicator mitt to be cut; a heating element associated with the tooling body, the heating element being shaped so as to match or substantially match a shape of the weld bead so as to create a perimeter weld for the applicator mitt when engaged with the tooling body; and an ejector platen which is actuatable relative to the tooling body to eject a cut and welded mitt away from the tooling body. The system can further comprise a conveyor device adapted to feed uncut and unwelded mitt material towards the applicator mitt tooling and a tooling actuator adapted to actuate the applicator mitt tooling relative to the conveyor device.

A pipe-liner system for lining a pipe and methods of use thereof. A continuous, eversible extended liner is formed from a pipe-liner attached to an extender-tube via a substantially leak-proof connection there between. Lengths of the extender-tube and the pipe-liner are each chosen so that the pipe-liner is caused to be accurately positioned within the pipe upon everting the extended liner into the pipe by a pressurized fluid. The pipe-liner is held against an interior surface of the pipe being lined by inserting an inflatable bladder into the extended liner and filling the bladder with pressurized fluid. When a resin in the pipe-liner has hardened, the bladder is removed and the extender-tube is detached from the pipe-liner.

A maleimide-based copolymer containing: 40% to 65% by mass of an aromatic vinyl-based monomer unit; and 35% to 60% by mass of a maleimide-based monomer unit, in which a residual amount of an aromatic vinyl-based monomer is 200 to 2000 ppm by mass, and a residual amount of a maleimide-based monomer is 30 to 400 ppm by mass.

The present disclosure provides an apparatus for forming a stream of individual packets, comprising a folder arranged to form a tubular web structure, a feeder arranged to feed the formed tubular web structure to a nip; a first rotor comprising a first sealing jaw and a knife, a second rotor comprising a second sealing jaw and an anvil, the sealing jaws, the knife and anvil rotating into opposing relation at the nip so as to form a severed, completed packet beyond the nip. The apparatus includes an open ended packet catcher adjacent the first and second rotors, which is arranged to catch the severed, completed packets beyond the nip whereby a stream of packets is established. The packet catcher includes a stripper disposed in a proximal location to at least one of the anvil, the knife and the sealing jaws when the anvil, the knife and/or the sealing jaws are rotated beyond the nip, whereby, should a completed packet stick to any of the anvil, the knife and/or the sealing jaws, the stripper is operative to free the stuck packet from the anvil, the knife and/or the sealing jaw. The present disclosure provides a fin sealer and method to seal a radially outwardly directed fin of a tubular web structure by directing the fin through a nip between a first and a second fin sealing rollers while communicating heat to the fin through at least one of the fin sealing rollers, the fin sealer being further arranged to maintain a nominal face-to-face relation between an outer annulus of the first fin sealing roller and an outer annulus of the second fin sealing roller with a flexible connection between a hub element of the second fin sealing roller with the outer annulus of the second fin sealing roller. A cooling system is also provided, which is operative upon one of the rotors of a cut and seal station.

A hollow structure for a face mask includes an inner wall, an outer wall spaced from the inner wall to define a hollow area between the inner wall and the outer wall, and a bottom wall that couples the inner wall to the outer wall. A first portion and a second portion together define a closable opening into the hollow area. The second portion is coupled to the outer wall by a bi-stable membrane that allows the second portion to move between (1) a first, opened position in which the second portion is spaced from the first portion to allow access to the hollow area through the opening, and (2) a second, closed position in which the second position abuts the first portion to close the opening.
