Abstract
An apparatus for producing at least one PLA tape includes a heating device for heating a tapelike extruded PLA film. The apparatus further includes a slitting device for slitting the PLA film heated by means of the heating device into the at least one PLA tape. The apparatus further includes a control unit which is configured to control the heating device in such a way that the PLA film is heated by the heating device to a PLA temperature in the range from 40 to 70° C. The apparatus further includes a drawing device downstream of the slitting device.
Claims3
An apparatus for producing at least one polylactide (PLA) tape, comprising:
- a heating device, comprising at least one heated godet for heating a tape-shaped extruded PLA film;
- a control unit which is configured to control the heating device in such a way that the PLA film is heated by the heating device to a PLA temperature in the range from a glass transition temperature to 70° C.;
- a slitting device for slitting the PLA film heated by means of the heating device into the at least one PLA tape, while the PLA film has the PLA temperature in the range from the glass transition temperature to 70° C.;
- and
- a drawing device downstream of the slitting device.
