20130264820 | DEVICE AND METHOD FOR PRODUCING THE MOUTHS OF BIAXIALLY ORIENTED PLASTIC TUBES WITH INTEGRATED SEALING GASKETS - The apparatus comprises a first sector wherethrough is introduced the biaxially oriented pipe and the gasket, a second sector, with diameter greater than that of the first sector, and a third sector, concentric to the second sector. The first sector is formed by at least three segments separated by isolating washers, so that at least two of said segments of the first sector, the second sector and the third sector are connected to means of heating and/or means of cooling regulated by a control unit which allows the selective and independent variation of the temperature of said segments and sectors and therefore of the pipe to favour the modelling of the socket with the integral gasket avoiding the disorientation of the pipe. | 10-10-2013 |
