Abstract
The present invention relates to an apparatus and a process for semicontinuous production of a semifinished sheeting constructed from unidirectionally endless-fibre-reinforced sheeting sections and also to a process for producing this semifinished sheeting, wherein the fibres in the final semifinished sheeting are aligned at an angle x having a magnitude from non-0° to 90° inclusive to the longest axis of the final semifinished sheeting.
Claims12
An apparatus for semicontinuous production of an x°-tape which is a semifinished sheeting constructed from unidirectionally endless-fibre-reinforced sheeting sections, wherein the fibres in this semifinished sheeting are embedded in a matrix of polycarbonate and aligned at an angle x having a magnitude from non-0° to 90° inclusive to the running direction of the x°-tape, comprising the following main components:
- (A) a cutting device;
- (B) a handling device;
- and
- (C) a joining device,
- which follow one another in the above order in the apparatus, wherein the main components are arranged such that in plan view the main axis of the apparatus forms a straight line.
A process for producing an x°-tape which is a semifinished sheeting constructed from unidirectionally endless-fibre-reinforced sheeting sections, wherein the fibres are embedded in a matrix of polycarbonate and in this semifinished sheeting are aligned at an angle x having a magnitude from non-0° to 90° inclusive to the running direction of the final semifinished sheeting, comprising the following process steps:
- (1) cutting the 0°-tape into sheeting sections;
- (2) rotating the sheeting sections by the magnitude of the angle x;
- and
- (3) cohesively joining the sheeting sections to afford the x°-tape,
- wherein the advancement direction of the 0°-tape, of the sheeting sections cut therefrom and of the x°-tape during production thereof is kept unchanged.
