Method for producing a cross-laminated cloth-like product from wide warp and weft webs

In the method for forming a crosswise structure of wide warp and weft webs without leaving any gaps between each of the weft webs in the production of a cross-laminated cloth-like product, where a warp web is continuously fed to travel in the warp direction of the product to be prepared and weft webs cut to a length corresponding to the width of the product to be prepared, are fed horizontally one by one along the line crosswise to that of production of the product and after cross-overlaid, the resulting structure of warp and wefts is fixed by a binder,

• an improved method for temporarily forming a continuous row of cut weft webs arranged in side by side relationship before fixing said warp and weft structure,
• which comprises:
• causing a warp material to travel horizontally along the line of production of product, while intersecting the feeding line of cut weft webs carried on a conveyer and travelling horizontally and crosswise thereto and vertically apart therefrom, said warp material being wetted on the surface thereof to be opposed to the cut weft webs, with a liquid having adhesion property, and having a sufficient width for covering the width of the warp web and a sufficient effective surface area for picking up the whole of one of the cut weft webs in the flat state, when wetted with said liquid;
• at each time when one of the cut weft webs comes to the position wholly overlapped with the travelling warp material, subjecting at least the part of the warp material facing the one of the cut weft webs to a sudden reciprocating vertical motion so as to touch and pick up the cut weft web by temporary adhesion to the warp material due to the action of said liquid having adhesion property;
• and
• repeating the above-mentioned reciprocating motions of the warp material successively, whenever the warp material advances by the distance corresponding to the width of the cut weft web at a speed so controlled that the cut weft webs are picked up one by one in a row without leaving any gaps between each other, and
• thereby effecting temporary forming of a continuous row of cut weft webs arranged in side by side relationship on the warp material.
