A method, and an apparatus associated therewith, for detecting plastic tube ends clamped in a butt welding machine, the plastic tube ends being planed by means of a plane, which can be introduced between the plastic tube ends, and subsequently being heated by means of a heating mirror, which can be introduced between the plastic tube ends, and the plastic tube ends are welded together after removal of the heating mirror, the plane and/or the heating mirror being tilted in between the plastic tube ends by means of a controlled movement, wherein detection or sensing of the plastic tube ends during the controlled movement of tilting in the plane and/or the heating mirror is carried out by means of at least one sensor arranged on the plane and/or on the heating mirror.

A method is described for opening a heat bonded sterile connection that includes a skin of material blocking flow between the connection site. The method includes applying external pressure to the connection site.

A device for end-side welding of plastic profiles, preferably pipes, containing tensioning devices for retaining the plastic profiles in a coaxial position in relation to one another, a heating plate for generating heat rays for contact-free heating up of the plastic profile ends and a reflection outer ring for reflection of the heat radiation onto the plastic profile outer side, wherein a reflection inner ring is arranged on the heating plate, wherein the reflection inner ring reflects the heat rays of the heating plate onto the plastic profile inner side.

A socket fusion jig includes a pipe saddle and coupling saddle spaced apart. Rotation of a handle causes the pipe saddle and coupling saddle to move laterally relative to one another so that the pipe held in the pipe saddle may be fused to the coupling held in the coupling saddle.

A tool for fixing a protective textile sleeve about an elongate member contained therein, and method of use thereof is provided. The tool includes a clamp assembly having opposed clamp members. Each of the clamp members has a clamp surface for abutting the textile sleeve. Each of the clamp surfaces includes a plurality of heating members operably connected to a source of power. The heating members within each clamping surface are supported for independent radial movement relative to one another in response to engagement with an outer surface of the textile sleeve to allow the clamp surfaces to automatically conform to the arcuate shape of the sleeve and elongate member being clamped therebetween.

A method is described for opening a heat bonded sterile connection that includes a skin of material blocking flow between the connection site. The method includes applying external pressure to the connection site.

A method and apparatus for attaching a branch polymeric fitting to a host polymeric pipe in which a flexible heating blanket is inserted between and used to heat the respective branch and host pipe surfaces. When the parts reach the appropriate temperature, the pipes are separated a small distance and the heating blanket is removed. The branch fitting and host pipe are then fused by placing the heated pipe ends in contact and applying pressure.

A chuck for gripping and moving cylindrical bodies, in particular fittings and pipe segments, including a main body defining an axis of rotation and a plurality of jaws fastened to the main body; the jaws are movable between a position of maximum closure, in which they are at the minimum distance from the axis of rotation, to a position of maximum opening, in which they are at the maximum distance from the axis of rotation; the chuck has an adjuster means for adjusting the positions of maximum closure and maximum opening and a movement means for moving the jaws between the positions of maximum closure and maximum opening; the chuck includes a fixing means adapted to allow the axial fixing of the chuck to a support member and the connection of the chuck to the support member so that they are angularly rotatable with respect to each other.

A pipe processing apparatus, for forming branches on pipes made of thermoplastic material, including a base adapted to be fastened to the outer wall of a pipe and a supporting structure which extends from the base; a support member is slidingly associated with the supporting structure and is adapted to receive an interchangeable processing/handling means configured to interact with the pipe; the apparatus also includes a movement means which engages the support member in order to move it on command along a processing axis. The supporting structure includes a single elongated structural element.

An equipment for manufacturing trampoline includes a rack, a rotation seat, a supporting platform, a plurality of fixing members, a driving member, a driving assembly, and at least one welding device. The rotation seat has a bearing rotatable with respect to the rack. The supporting platform is connected to the bearing. The fixing members are detachably disposed on the supporting platform. The driving member surrounds the supporting platform and is linked-up with the supporting platform. The driving assembly is connected to the driving member.
