An extrusion line for the production of peroxide cross-linked polyethylene pipes includes a cross-linking oven () having an actuated deflection roller (). The cross-linking oven has a first heating section (A) that extends from an inlet to said deflection roller () and a second heating section (B) that extends from said deflection roller to an outlet. An element is provided for adjusting a height of the deflection roller () and an angle of the first and second heating sections (A, B) relative to a horizontal plane.

Extrusion line for producing peroxide-cross-linked polyethylene pipes

A method and extrusion line for producing peroxide-cross-linked polyethylene pipes in an extrusion line having an extruder, a cross-linking furnace and a flue. The extruded tube is subjected to a stretching process, and the cross-linking furnace has a first heating section that extends from its inlet to an actuated deflection roller and a second heating section from the deflection roller to its outlet. The stretching process in the first heating section and the stretching process in the second heating section are monitored and regulated in such a manner that the necessary stretching of the pipe takes place primarily in the first heating section, and the stretching of the pipe in the second heating section is subjected to zero adjustment. In this case, the height of the deflection roller(s) of the cross-linking furnace and the angle of the heating sections to the horizontal plane can be height-adjustable.

Method and extrusion line for producing peroxide-cross-linked polyethylene pipes

An apparatus for producing a mixture of various bulk materials, comprising a weighing device that is carried by the framework of the apparatus. A weighing container is suspended or supported by the weighing device, and is adapted to receive a desired mixture of bulk material components from supply containers via an upper inlet. A mixing device extends from above into the weighing container and is driven by motor-transmission means that is mounted on the framework and is gravimetrically separate from the weighing container. The mixing device is permanently suspended on the motor-transmission means free of the weighing container.
