Abstract
A plurality of strands is introduced by a reciprocating weft laying device into a layer of paste-like bonding material deposited on the upper surface of an endless belt. A plurality of warp strands extending in the warp direction is introduced into the paste over the first mentioned strands. A second plurality of strands in the weft direction is similarly introduced by means of a second reciprocating weft laying device and a second plurality of strands in the warp direction is introduced over these second weft strands. The paste-like bonding material is then cured by a heated roller to produce the finished material. Material may be made having only one set of warp strands and one set of weft strands or more than two sets each of warp and weft strands.
