SINGLE SCREW PLASTICISING UNIT HAVING FIBRE SUPPLY DEVICE FOR PRODUCING A FIBRE-CONTAINING PLASTIC MELT

摘要

The invention relates to a single screw plasticising unit (3) for producing a fibre-containing plastic melt, having a screw (5) which can be rotated in a cylinder (4), a first opening (8) for supplying a plastic material to be melted, a second opening (9) for supplying fibre bundles (10a to 10f), and a fibre supply device (13) comprising a fibre creel (14) with fibre spools (15, 15a to 15f). The fibre supply device is equipped with hoses (16) through which the fibre bundles are fed, the hoses being laid such that there are circular segments (31 to 37), each with a circular segment angle (α1 to α7), and/or a wrap around an imaginary (22) or a real (23) wrap object with a predefinable wrap angle (ß). A fibre braking force according to the Euler-Eytelwein effect is applied to the fibre bundles which are guided in circular segments and/or a wrap-around.
