ABSTRACT BACKING MATERIAL FOR CARPET UNDERLAY A composite sheet material which is particularly useful as a backing material for carpet underlay is a stitched crepe paper sheet 5 with rows of apparent projections 13 formed therein between parallel rows of stitches 10 by deforming the crepe paper sheet without puncturing the paper. The stitches 10 substantially restrict the extensibility of the crepe paper sheet and the apparent projections 13 are formed at a position in the crepe paper sheet 5 directly in line with the ends 11 of the stitches 10. According to the preferred method described, each apparent projection 13 is in reality a depression between two projections formed in the opposite surface of the crepe paper sheet without puncturing the paper. In an alternative embodiment there is a pair of apparent projections 13 formed in the crepe paper sheet 5 between adjacent rows of stitches 10.
