Patent ID: 7517426

Claim:
A sheet material having a longitudinal configuration, said longitudinal sheet material being formed so that a plurality of unit sheet materials are adjacently arranged to each other with side by side configuration in two dimensional direction, before said unit sheet materials are put on a floor so as to be carryable, and wherein said sheet material is cut out to produce a backing layer used for recycled tile carpet, wherein said unit sheet materials are either one of a tile carpet comprising a fiber assembled layer comprising a plurality of loop piles or a plurality of cut piles both of which are flexible and tufted in a base fabric both of which being made of thermoplastic and organic material and a backing layer made only of thermoplastic synthetic resin, or a piece of fiber fabrication layer unit which has a predetermined unit surface area and which comprises a fiber assembled layer comprising a plurality of loop piles or a plurality of cut piles tufted in a base fabric both of which being made of thermoplastic and organic material and having a predetermined thickness with a fiber fixing portion containing therein said thermoplastic synthetic resin formed on a part of said fiber assembled layer unit, and at least on a part of a surface of said fiber fixing portion, a shearing separation treatment surface being provided; said longitudinal sheet material further comprising a first longitudinal sheet material and a second longitudinal sheet material, and wherein said first and said second longitudinal sheet materials are connected with each other with or without interposing a reinforcing sheet therebetween, in a way so that said backing layers or said fiber fixing portions of both said first and second longitudinal sheet materials are oppositely faced to each other, or so that said backing layers of one of said first and second longitudinal sheet materials are oppositely faced to said fiber fixing portions of said opposite longitudinal sheet material, or so that either one of said backing layers and said fiber fixing portions of either one of said first and second longitudinal sheet materials are oppositely faced to said fiber assembled layer of the other of said first and second longitudinal sheet material.
