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 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 apparatus for processing an elongated structure includes a mold within which an uncross-linked rubber material is placed, at least one heating unit configured to heat the mold, and a pressure device configured to press the rubber material using the mold heated by the heating unit to promote shaping the rubber material by the mold while proceeding the cross-linking of the rubber material. The heating unit includes a central heating device configured to heat a longitudinal central portion of the mold, multiple cooling devices configured to cool two longitudinal end portions of the mold, multiple intermediate heating devices configured to heat two intermediate portions between the longitudinal central portion and the longitudinal end portions of the mold, heat shield plates disposed between the central heating device and the intermediate heating devices, and heat shield plates disposed between the cooling devices and the intermediate heating devices.

A system and method are provided for manufacturing a plastic pallet having a plurality of runner assemblies with embedded support structures. Each runner assembly may include a top runner board, a bottom runner board, and a plurality of support structures embedded into the top and bottom runner boards. The pallet may be manufactured using heat to at least partially penetrate and soften the runner boards, to soften the support structures, and to weld the support structures to the runner boards in an embedded manner.

The apparatus 10 includes a table 12 which defines a flat top surface 14. Two spaced apart, parallel tracks 16.1, 16.2 are mounted on top of the surface 14. A first positioning arrangement 18, is displaceably mounted on top of the tracks 16. When in use, a plurality 5 of collector tubes 300 can be arranged parallel to one another on top of the frame 24 such that they extend along a displacement path 400 of the tracks 16 and are substantially perpendicular to tubes 306 and 308.

The connector (200) can join an end of a first flexible thermoplastic tube segment (202) to an end of at least a second flexible thermoplastic tube segment (202). The connector (200) is made of a thermoplastic material allowing, through heat fusion, to join the inner surface (244) of the receptacles (240, 260) of the connector (200) to the outer surface (206) of the corresponding tube segments (202), and this, without creating a gap or an irregularity inside the portion of the liquid circuit. The heat fusion can result in airtight and robust joints made with a high precision and that are uniform, even if they can be made under difficult conditions. The proposed concept can be particularly useful in sugar making.

Fluid flow conduits and apparatus and methods for joining the conduits, preferably in a sterile manner, are disclosed. Each conduit has a polymeric open end that is sealed by a sealing member that may include a heating element. The polymeric end material is melted, the sealing members are moved to expose the melted open ends of the conduits and the ends are brought together to form a fused or welded connection between the conduits.
