ABSTRACT:
A novel product wherein cut webs for wefts (which are abbreviated as weft webs) are successively connected in the warp direction by selvedges adhered onto both the margins of the weft webs, is provided by circulating two right and left heated belts having thereon a hot-melt type adhesive in a tacky state and spaced by the length of each of weft webs of a large width mentioned below; adhering onto each of the belts, selvedge materials which constitute the selvedges of final product and are hereinafter abbreviated merely as selvedges; suddenly dropping the two belts having the selvedges adhered thereonto, on the lower side circulating route of the belts, down onto one of weft webs loaded successively and at a given gap on a conveyer circulating below the belts perpendicularly thereto, over the length corresponding to the width of the weft webs, when both the ends of one of the weft webs and the corresponding belts overlap each other, thereby to adhere both the ends of the weft web onto the corresponding selvedges having said adhesive on their lower surfaces, and just thereafter suddenly elevating the belts thereby to strip and hang up the weft web adhered onto the selvedges from the conveyer; repeating the above-mentioned procedure; and peeling the resulting selvedges having successive weft webs adhered thereonto from the belts to give said novel product.
