Abstract
A multi-layer fabric for carrying and forming an embossed paper web is provided which comprises two separate woven fabric layers which are joined together, preferably during weaving. The top fabric layer is a very coarse mesh open fabric which supports the web and assists in forming the embossed characteristic of the web. The top layer is connected to a base fabric layer which is a substantially finer mesh. The layers are preferably interconnected by binder strands which interweave as structural warps or shutes of the finer mesh fabric layer.
