Methods and systems for no-glue pocketed spring unit construction. Rows of pocketed springs, preferably arranged into modules of more than two pocketed springs surrounding a central hole, are ultrasonically welded together when paired vibrating probes and anvils press layers of pocketed spring fabric from the rows of pocketed springs together and a welding pulse is transmitted to the vibrating probe.

There is described a unit for applying at least one pre-formed opening device onto a hole of a web of a packaging material, unit comprises an advancing means device for advancing the web along a path; and at least one application station, which is fed, in use, with pre-formed opening device and seals, in use, pre-formed opening device on the hole of web.

A method and system for inserting a liner and lining pipes from inside a water main or other larger pipe. The method and system generally includes inserting a string inside the first pipe between a first end and a second end, inserting the string through a liner positioning tool, attaching a first end of the string to the liner, and then pulling the liner into the first pipe with the first string such that the liner extends from the first end to the second end of the pipe. One end of the string may be attached to the liner by a pulling insert, which may be a threaded insert that screws into an end of the liner, and which may further include a fluid passage to allow hot water or other fluid to flow through the insert while the string is connected to it.

A welding device includes a pair of pressure rollers for pressurizing a web and a strip member, a feed device configured to intermittently or continuously feed the web and the strip member through the pair of pressure rollers, and the laser device configured to irradiate the web or the strip member with a laser beam at a position upstream of the pair of pressure rollers. The welding device may include a movement device configured to move the pair of pressure rollers upstream with respect to the web and the strip member during pause or stop of feed. Alternatively, the feed device may pause or stop the web and the strip member after retracting the web and the strip member by a certain length.

A description is given of a method for joining a first and a second film web (2, 2′) of a transfer film or laminating film, wherein the film webs (2, 2′) comprise a thermoplastic carrier film (21) and a decorative layer (23). Formed between the first and second film webs (2, 2′) is a common joining portion (3), in which the first and second film webs (2, 2′) are joined to each other by a welding process. A device for carrying out the method is also described.

A sealing strip holder for manipulating and transporting a sealing strip preform in an at least partially automated production process, the sealing strip preform preferably having limp properties. To make the manufacturing process faster and less expensive the sealing strip holder comprises at least one clamping jaw which interlockingly and/or frictionally engages at least one surface portion of the sealing strip preform.

A molding apparatus that adsorbs thermoplastic resin extruded in a sheet form from an extruding machine, onto a cavity of a mold, and shapes the thermoplastic resin into a shape according to the cavity is provided. The molding apparatus may include a frame that is positioned on a periphery of the mold and is movable relative to the mold, wherein a suction part for suctioning the thermoplastic resin is provided in a contact surface of the frame to contact the thermoplastic resin, and the suction part is provided in a linear shape along with a longitudinal direction of the frame positioned on the periphery of the mold.

A device for producing a packaged electrode includes: a conveyance unit configured to sequentially overlay the electrode and the pair of separators from a front end side in a conveying direction while conveying the electrode and the pair of separators; a first joining chip configured to join lateral edges of the pair of separators together; at least one second joining chip positioned downstream of the first joining chip in the conveying direction and configured to join the lateral edges of the pair of separators together. Front ends of the lateral edges of the pair of separators being sequentially overlaid while being conveyed by the conveyance unit are joined together by the first joining chip positioned upstream before the front ends are conveyed to the second joining chip positioned downstream.

A flow sensor includes an auxiliary channel having an opening into which a fluid to be measured is taken; a sensor element that measures the flow of the fluid to be measured; a housing that accommodates electronic parts; and a resin cover. The flow sensor is configured such that junctions of the housing and the cover are formed in locations where first target weld portions, which are formed so that the circuit chamber is surrounded, face each other and second target weld portions, which are disposed for additional reinforcement of the joints, face each other on a bonding face of the housing and a bonding face of the cover with a step being provided. The positioning of the housing and the cover is determined, and the first target weld portions are welded to each other and second target weld portions are welded to each other by way of laser radiation.

A flow rate sensor includes: a housing made from a resin material and having a bottom base portion and a side wall, at least one surface side of the housing being open; a cover made from a resin material, covering the one surface side of the housing, welded to an upper surface of the side wall of the housing, and defining, with the bottom base portion and the side wall of the housing, an auxiliary passage within which a gas to be measured flows that is taken in from a main passage; and a flow rate detection unit disposed within the auxiliary passage. A protruding portion for height control is provided to one of the housing and the cover at least in a vicinity of the side wall around the flow rate detection unit so as to suppress sinking in of the cover during welding.
