摘要： The invention relates to a method for feeding and treating plastic strands that are discharged from nozzles in a molten state by means of a cooling section in order to granulate the plastic strands. According to the invention, the plastic strands are partially crystallized in a temperature-adjusted liquid medium in a crystallization section once they are discharged from the nozzles, the liquid medium being maintained at a temperature above the glass transition temperature of the plastic strands. The invention further relates to a device for carrying out said method. The inventive device comprises a plastic melting device, a device for extruding the strands from nozzles, a crystallization section that is located directly downstream of the nozzles, and a granulation device that is located downstream of the crystallization section. The temperature of the crystallization section is adjusted by means of heating and/or cooling devices and is provided with temperature adjusting elements with which the temperature of the temperature-adjusted liquid medium can be adjusted to a temperature above the glass transition temperature of the plastic strands.

摘要： The invention relates to a device for granulating thermoplastics that are extruded from nozzles, the latter being provided in a nozzle disc in a substantially circular arrangement. Blades, which rotate about a blade carrier shaft and are held by a blade carrier in an oblique position in relation to the radial direction, sweep over said nozzles. The blade carrier shaft runs through the centre of the circular assembly and a cooling medium is fed to the nozzle disc and the blades to cool the granulated plastics. The blade carrier, together with the blade carrier shaft, is located in an essentially circular housing, which extends as far as the nozzle disc and into which a supply of cooling medium flows in a tangential direction, in order to create a circulatory stream in said housing containing the rotating blade carrier. The cooling medium rotates in the housing at a speed and in a rotational direction that essentially correspond to the rotational speed and rotational direction of flow passages in the blade carrier, by means of which the cooling medium is fed to the blades.

摘要： The invention relates to a device for adjusting the cutting gap between a rotor (1) with a cutting blade (11) which can be rotated about a rotor axis (10) and a lockable counter-blade body (12) which bears a cutting edge (9). Said counter-blade body can be adjusted by an adjusting mechanism which operates in opposition to the cutting blades (11) of the rotor in a perpendicular direction in relation to the rotor axis, in order to optimise the cutting gap. Said adjusting mechanism has a carriage (13) which is guided in a linear guide (8) and the linear guide (8) is positioned at a slight angle to the rotor axis (10) parallel. The counter-blade body (12) is either located on the carriage (13) in such a way that the parallel position of the cutting edge (9) and cutting blade (11) is maintained, or a U-shaped counter-blade body (12) is provided, whose limbs (14, 15) are forced apart elastically by pressure elements (6).

摘要： The invention relates to a method and a device for producing crystallisable plastic material, especially PET, by means of a conventional SSP treatment. The plastic material only cools down to the crystallisation temperature before crystallisation. After granulation and crystallisation, the plastic material is subjected to a sieving process in a temperature remaining approximately the same.

摘要： The invention concerns a closable extrusion nozzle for thermoplastic materials, with a nozzle plate (4) containing nozzles permitting the extrusion of the thermoplastic material from a hopper (1) and with a perforated plate (7), disposed upstream of the nozzle plate, whose apertures (8) can be brought in and out of alignment with the nozzles by displacing the perforated plate (7) with respect to the nozzle plate (4). The nozzle plate (4), which is U-shaped in cross-section, with the arms of the U at right angles to the direction of displacement of the perforated plate, is designed as a housing for the perforated plate (7) enclosed within it. A sealing surface (15) on the perforated plate (7) rests against the flat housing floor (5) in which the nozzles (6) are located, there being a gap between the perforated plate (7) and the housing at least in the curved regions (16, 17) of the floor, and the region in which the seal is formed by the sealing surface (15) resting against the floor (5) being limited to a narrow zone round the nozzles (6).

摘要： Disclosed is a device for cooLing, granulating and drying molten strands of synthetic thermoplastic material ermerging form dies. It comprises a cooling unit which feeds the strands into a bath of cooling liquid and to which is connected a granulator housing with a cutting roll, the latter being connected to an outlet duct with a sieve to separate the thermoplastic material from the cooling liquid. The sieve is arranged in such a way that the grains separated from the strands by the cutting roll impinge directly on the sieve at basically the same speed as that imparted to the grains by the cutting roll.
