Abstract: In a process of welding pieces of tubing into films with a central electrode the central electrode is divided to facilitate the welding in a single process. In the case of tools with or without a central electrode, electrode lamellae lying next to one another have a free visual connection between edges lying towards the insert piece to obtain a tight welded joint.

Abstract: A wrinkle control process for manufacturing a closed cross-sectional, composite laminate structure on a male tool cured under temperature and pressure. The process includes the step of creating a plurality of filled or unfilled depressions at strategic locations in the laminate prior to curing. The depressions are created by depression forming elements that have a predetermined size designed to create a depression in under plies, alone or combined with intensification techniques. The depressions may be left unfilled or be partially or completely filled. Depression forming elements are removed after cure or remain part of the structure.

Abstract: Apparatus and methods are provided for substantially continuously forming thin-walled sleeves that may be incorporated into tubular devices sized for introduction into a patient. In one embodiment, a pair of sheets including coated surfaces oriented towards one another are directed through a cutting apparatus to cut the sheets into multiple pairs of strips. The pairs of strips are bonded together to create a plurality of sleeves having lumens defined by the coated surfaces. In another embodiment, a sheet having a coated surface is fed through a cutting tool to separate the sheet into a plurality of strips, and the strips are formed into sleeves, e.g., by feeding the strips through a die or mandrel using a substantially continuous process. Optionally, the sleeves may be subsequently cut into individual tubular devices and/or further processed, e.g., by providing one or more layers around the sleeves to create catheters, sheaths, or other apparatus.

Abstract: A laser strikes and aseptically heats or sterilizes the end of two flexible tube ends for connection. Tube holders are pushed toward each other to bring the tube ends into contact. A weld detector checks the characteristics of the weld. A laser optics assembly may be used to change the direction of the laser and focus the laser at the tube ends. In addition, a crimping device is used to compress a single flexible tube for disconnection. The laser strikes the compressed area. The crimping device continues to pinch the area and forms a seal in the tube. The tube is separated into two tube segments, each segment has a sealed end.

Abstract: A belt seam treatment apparatus includes a support element with a smooth surface that supports the seam region of the belt, a heat source that heats a treatment strip and the belt seam region, and a pressure applicator that forces the treatment strip against the belt seam region. The support element can be a tube over which the belt hangs and can include a vacuum belt hold system that secures the seam region against the tube during treatment. The heat source can be an infrared laser or an infrared lamp. Optics form a heat spot or a heat line on the strip and seam region, and a pressure wheel traverses the seam region after heating to compress the strip and seam and bond a thermoplastic polymer of the strip to the seam region of the belt.

Abstract: For weld bonding polymeric components, a bond monitoring device is utilized to sense emissivity from a bonding site to preferably determine the temperature of the material at the surface of the bonding site, in order to provide feedback information to a current generator that controls the thermal energy that is transferred to the bonding site.

Abstract: An in-line continuous feed sleeve labeling machine labels containers, such as beverage containers, in an in-line fashion maintaining the elevation of the containers during their linear transport. The in-line continuous feed sleeve labeling machine of the present invention receives bottles in flood feeder or linear fashion. A timing screw or the like properly separates, and both spatially and temporally disposes, the containers for sleeving. The timing screw propels the containers onto a pedestal system. The pedestals of the pedestal system maintain their horizontal nature due to offset pivotable attachments to the track system upon which they travel. A sheet of film is unspooled from an unwind roll and passed through a tube forming apparatus that overlaps the edges of the film. The overlapping edges completing the tube enclosure are connected using ultrasonic welding or the like. The sleeve is then passed to an iris carrier.
