PROCEDURE, DEVICE, AND COMPOSITE VELO FOR REINFORCEMENT OF ANOTHER VEIL PREPARED BY THE AIR DEPOSITION PROCEDURE.

摘要

Procedure for the consolidation of a veil prepared by the air deposition process, consisting of two external layers made of thermally activated cut fibers and a layer disposed between them made from cellulosic fibers as a super absorbent pulp, by consecutive formation, in first of the base or lower layer, after the application of the pulp layer and finally of the upper layer, characterized in that the two outer layers of the composite veil have been made from fibers of 8 to 10 mm in length and because the veil of three layers for its consolidation, as well as for the intimate union of the layers applied only by the process of air deposition are subjected to a hydrodynamic punching.
