ABSTRACT:
A multi-layered glass fiber sheet is formed by alternately laying groups of glass fiber warps and glass fiber wefts upon one another. The basic structure of the multi-layered glass fiber sheet is produced by deforming a portion of a circulating endless belt into a cylindrical shape in a section of the path of the belt, guiding glass fiber warps in the longitudinal direction of the cylindrically deformed portion of the belt to cover the entire periphery of the cylinder of the belt, winding glass fiber wefts about the cylinder of the glass fiber warps at right angles or at angles less than right angles to the warps, applying additional glass fiber warps to the cylinder in the longitudinal direction of the cylinder to form a multi-layered cylindrical product comprising warps and wefts, and ripping or cutting the cylindrical product along a line in the longitudinal direction of the cylindrical product by a cutter to provide a multi-layered sheet.
