Abstract: A novel apparatus is described for granulating plastic strands (4) which emerge from nozzles (3) in molten form and are supplied to a following, downward inclined runoff channel (1) in which the plastic strands are transported by a liquid stream, in particular water stream. Further the apparatus has a dewatering zone (1b) for the plastic strands (4) and a granulator (6) disposed after this dewatering zone. Between the dewatering zone (1b) and the granulator (6) there is at least one tempering zone (9) comprising a rigid, unmoving channel (15) and integrated transport rolls (16) for the plastic strands (4) and having a length such that the temperature differences of the plastic strands (4) across their cross section are largely equalized during their holding time in the tempering zone (9).

Abstract: A device for cooling and granulating strands of plastic which emerge in molten form from dies (3) before being fed, either directly or via a chute (22) which can be positioned underneath the dies and has a cooling water supply, to a subsequent flow channel (1) which has at least one device for producing a stream of coolant. From the flow channel (1) the strands (4) are fed into a granulator (16) which is provided with at least one blade system comprising a rotating shearing blade (13) and a counterblade (12) and used for granulating the strands (4). The device is without a pair of feed rollers as an assembly belonging to the granulator (16) but has a pair of draw-off rollers (20, 21) at the end region of the flow channel (1).

Abstract: In order to simplify cleaning work in a granulator for strand materials with a feed device for taking up the strand material and conveying it to a subsequent shearing blade roller which rotates contrary to the direction of conveyance of the strand material and operates against a stationary anvil blade, wherein the feed device comprises a lower and an upper feed roller, of which at least one is drivable, wherein a wiper blade is associated with the lower feed roller, and wherein the wiper blade and the anvil blade are fixed in position on a carrier arranged between the lower feed roller and the shearing blade roller, it is suggested that the lower feed roller be movable between an operating and a non-operating position, wherein in its non-operating position the lower feed roller is arranged at a distance from the carrier and the wiper blade, and that the lower feed roller be lockable in its operating position.
