Abstract: A self-adhesive sheet is described for multiple uses and especially as a carpet liner or an acoustic coating. The sheet includes a base sheet in the form of a polypropylene web, a thin coating of natural or synthetic non-slip material such as latex foam adhered to one side of the base sheet, a coating of adhesive applied to the other side of the base sheet, and a protector sheet covering the adhesive coating, which may be peeled off to make the sheet self-adhesive. Preferably, the foam coating is provided with a pattern in relief to ensure a relatively bodied structure in relation to the weight of latex used as well as an agreeable appearance. The self-adhesive sheet is light, flexible and easily handled and it may be cut to the desired size and shape using scissors or the like.

Abstract: The present invention relates to a process for the manufacture of tufted rugs and carpets, or similar products, characterized by the fact that a first application of yarns is inserted by a bank of needles over a prewoven base then over which a second application of yarns is made in a different direction from the first, forming a two directional tufted structure; the process can produce tufted carpets in any size and shape without joints, and results in self-supporting yarns. It also manufactures other tufted textile products through the two and the three-directional tufting process.
