Abstract
In order to laminate a fabric to a plastics material grid formed of oriented strands connected by junctions having thicker and non-oriented or less-oriented nodes, the fabric and the grid having the same melting temperature, the grid is heated by a drum to melt the surfaces of the nodes, and the grid and the fabric are passed through a nip formed by nip rollers, the fabric having been pre-heated by passing around a preheat roller. One nip roller has surface protuberances formed by knurling of such a size that a number of protuberances engage (by way of the fabric) each node of the grid.
