PROCEDE ET MACHINE DE FABRICATION D'UNE MATIERE SOUDABLE PAR HAUTE FREQUENCE, NOTAMMENT EN BANDE, ET MATIERE AINSI OBTENUE

摘要

A high frequency-weldable material for use in the manufacture of a composite material containing said weldable material comprises a structure which is permeable to gas, vapor and liquid and which is free of a tendency to rustle when subjected to deformation, and discrete particles arranged on at least one boundary surface of said structure and consisting of a thermoplastic synthetic resin, which is adapted to melt and to produce a high frequency-welded joint under the action of a high-frequency field and to resist the action of detergents and dry-cleaning agents.
