The invention relates to a method and a device () for dewatering and drying a mixture made of plastic granulate and water, having at least one mixture intake (), through which the mixture is supplied to the device (), having at least one water outlet (), through which the precipitated water is removed from the device (), having at least one granulate outlet (), through which the dried granulate is removed from the device (), the device () having a dewatering line (), along which the mixture is dewatered, and the device () having a drying line (), along which the dewatered granulate is dried. The device () comprises at least one sensor (), using which at least one property parameter of the granulate, in particular the temperature and/or residual moisture of the dried granulate, may be measured directly or indirectly, the device () comprising at least one final control element (), and the property parameter monitored using the sensor (), in particular the temperature and/or residual moisture of the dried granulate, being able to be influenced as a function of the measured values of the sensor () using the final control element ().

Device and method for dehydrating and drying a mixture of plastic granules and water

The invention relates to a method for granulating and crystallizing thermoplastic polymers, the granules being contained in a liquid after granulation of a polymer melt and the granules being nucleated in the liquid once the pressure of the liquid is increased and the temperature of the liquid is increased, and the granules being crystallized in the liquid once the pressure of the liquid is again increased and the temperature of the liquid is again increased. According to the invention, the granules are removed from the liquid once the pressure and the temperature of the liquid containing the granules have been reduced.

Method for granulating and crystallizing thermoplastic polymers

The invention relates to a method for the production of granulate grains of polymers from thermoplastic polyesters or copolyesters from a polyester melt using an extrusion granulator. The polyester melt is fed to nozzles of the extrusion granulator and then, with draw-in rollers, to the granulation device via an extraction section as extrusions exiting from the nozzle, wherein, e.g., an extrusion extraction speed is set by the draw-in rollers. The invention also relates to an improved extrusion granulator according to the invention having a wave device between the nozzles and the extraction channel, and granulate grains produced according to the method according to the invention.

Extrusion granulation method and device, and granulate produced therefrom

A method of producing seat belt webbing is proposed in which the webbing is first woven using at least two synthetic yarns of different colours of which at least one yarn is spun-dyed, and using weaves that are known per se, and that is distinguished in that the webbing is then subjected to treatment in a water-bath containing at least one disperse dye. Seat belt webbing produced in this way and seat belts containing such webbing are also claimed.
