Process for fabricating a reinforced drain cover, characterised by the fact that it consists of moulding (4) a number of reinforcement layers (7) composed of one or more fibre strands (8) with a predetermined diameter (D2), which in turn are composed of interwoven fibres (9) or bundles of fibres (9), and there interwoven a certain number of extending fibres at the exterior perimeter of the fibre strands (8) with a certain length (L) and the layered spacers extending themselves in between, horizontally and vertically, preferably with a higher rigidity than the armouring strands (8). The filling of the mould with plastic (11), so that all fibres (9) and fibres (9.1) extending at the exterior perimeter of the fibre strands (8) have a maximum contact with the injected plastic (11), by covering the fibre strands (8) with one predetermined thickness (D4) and (D5) of the plastic covering layer, and after hardening of the plastic (11), the removal of the thus obtained drain cover (1) from the mould (4). |
