  • Patent number: 8939750
    Abstract: The invention relates to a device for pelletizing at least one strand of material to be pelletized. Said device comprises a cutting device with two blades that can be displaced relative each other, at least one feed roller and at least one strand feeder for feeding the strand to the cutting device. An additional tab-shaped rectification guide is arranged downstream of the strand feeder in the region directly in front of the feed roller and next to the same, said guide being adjustable and movable in relation to the strand feeder. The rectification guide can be used to adjust the angle at which the strand is fed to the feed roller.

  • Patent number: 8337189
    Abstract: The invention relates to a device for producing pellets from plastic material or from material to be pelletized. Said device comprises a continuous casting device (1) from which at least one strand (2) of the material to be pelletized is issued, and a belt conveyor (3) comprising at least one conveying belt (4) on which the strand (2) can be fed to a pelletizer (5), said pelletizer breaking the strand up into pellets (6). The invention is characterized in that the belt conveyor (3) has a switchable direction of conveyance of the conveying belt (4), a direction of feed conveyance towards the pelletizer (5) and a direction of discharge conveyance away from the pelletizer (5). The invention also relates to a method for operating said device.

  • Patent number: 8147738
    Abstract: 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.

  • Publication number: 20100297278
    Abstract: The invention relates to a device for pelletizing at least one strand (1, 1?) of material to be palletized. Said device comprises a cutting device with two blades (5, 6) that can be displaced relative to each other, at least one feed roller (3, 4) and at least one strand feeder (2, 2?) for feeding the strand (1, 1?) to the cutting device. An additional tap-shaped rectification guide (7, 7?) is arranged downstream of the strand feeder (2, 2?) in the region immediately in front of the feed roller (3, 4) and next to the same, said guide being adjustable in its inclination and moveably in relation to the strand feeder. The rectification guide can be used to adjust the angle at which the strand is fed to the feed roller.
