developments products & Saw and belling machine for PP multilayer pipe line THE TRS/C/Sy 250 sawing machine features recent plant solutions and technical solutions that have been introduced to fit the increased production capacity of modern extrusion lines. The saw has cutting tools inside the planetary group (rotor) and has a mechanical system to control the position of the cutting tools on the external pipe wall around the cutting area. The cutting unit has two cutting arms each with a different cutting tool: one is a special Sica design milling cutter for chamfering the pipe (which has been modelled based on the particular shredding characteristic of the material), and the other is for the final swarfless cut of the pipe. This solution allows a clean chamfer and cut without any chips inside or outside the pipe. TRS/C/Sy 250 processes pipes from 32 to 250mm diameter. For pipes up to 12mm wall thickness it can cut and chamfer, while pipes up to 40mm can only be cut. Everbell/H 315 PSP is an automatic belling machine for shaping O-ring sockets for PP and HDPE pipes for indoor draining and sewage applications (which can also be used for PVC-U pipes). The machine can socket solid wall pipes or multilayer pipes from DN 50 to DN 315 with pipe lengths from 0.5m to 6m plus socket. The H version of the machine features heating and cooling systems that reduce thermoforming time. The first heating station, instead of the traditional contact oven, has an oven with lamps to emit IR shortwaves. The cooling station uses an exclusive Sica-patented convective cooling system with a cooling fluid that goes through an internal refrigerating system. The forming stage uses a patented Sica PSP system (Permanent Socket Profile), which produces an O-ring socket with an internal dimensionally calibrated surface and a stable shape.
