The film sealing and wrapping machine with a rotary cut and seal jaw is provided. The rotary cut and seal jaw has an internal sliding mechanism which provides for smooth and quiet operation. The rotational speed of the jaw may be varied to increase through put and to provide for a title bag around products. The rotary cut and seal jaw may comprise a seal bar and pressure pad may both be spring loaded to self align the seal bar and pressure pad during the sealing and cutting process. Lastly, a gap defined by a belt disposed upstream and downstream of the seal bar and pressure pad may be mechanically linked to the pressure pad through a control carriage.

The purpose of the present invention is to provide a heat-sealing device capable of preventing problems associated with cap sealing performance and/or sensation of the cap being open due to an inappropriate cap temperature. For this purpose, this heat-sealing device (10), which is used in a manufacturing apparatus (100) for manufacturing a product for which an opening part (1A: mouth part) of a container (1) is sealed with a cap (2), is provided with: a pressing plate (5) which is disposed on a path along which the containers (1) move; a heating unit (3) and sealing heads (4) for pressing the caps (2) sealing the container (1), the heating unit (3) and sealing heads (4) being arranged on the pressing plate (5); a temperature measurement device (7) for measuring the temperatures of the sealing heads (4); and a control device (8: control unit) for transmitting control signals to a container conveyance drive source (for example, inverter) in accordance with the measurement results from the temperature measurement device (7).

There is provided a polymer fabrication method for forming 3-dimensional shapes from a sheet polymer blank (10) by machining at least one re-entrant, elongate groove forming a reduced thickness portion (25) permitting the blank to be folded and having opposed edges (12) at the surface, folding the blank about the groove to form at least a portion of the 3-dimensional shape, the re-entrant of the groove forming an elongate chamber (21) adjacent the reduced thickness portion and opening through an elongate gap (20) between the opposed edges, hot air welding the opposed edges across the gap with filler rod (22), and heating the reduced thickness portion to a selected thermo-reforming temperature via the chamber.

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.

An ultrasonic welding system includes an ultrasonic welding stack that is movable to initiated a welding operation. A plurality of sensors measure respective control variables and output control signals corresponding, respectively, to the control variables. A motion control system is coupled to and causes controlled movement of the welding stack, including initiating the welding operation. The motion control system determines, based on the control signals, control inputs such that any motion of the welding stack, subsequent to the initiating, is initially delayed until the control signals satisfy a predetermined condition. In response to the predetermined condition being satisfied, the motion control system causes the welding stack to move in accordance with a weld profile.

A female loop portion for a hook and loop self-adhesive, comprising a film (1) made of at least one thermoplastic and a plurality of filaments (2) which are separate from one another and attached to one of the surfaces of the film, each filament comprising a series of fastening sections (15) and a series of loop sections (4) alternating with the fastening sections, the filaments being attached to the film along the fastening sections while the loop sections are at a distance from the film so as to form loops, and characterized in that a cross-sectional area of one loop section of a filament is less than a cross-sectional area of one fastening section of said one filament.

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 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 resin pipe 30 and a resin member 31 are fixed to a setting portion 5 provided on the front side of a base 6, and a timing pulley 13 which is provided on the back side of the base 6 and to which a light emission unit 3 is attached is rotated. As a result, the light emission unit 3 applies laser light 20 to a junction 32 between the resin pipe 30 and the resin member 31 while revolving around the junction 32. This makes it easy to fuse and join the entire outer circumferential surface of the resin pipe 30 with the entire inner circumferential surface of the resin member 31, which are variously shaped and sized.
