Abstract
Textile fabrics are firmly lap welded to each other by superposing two end portions of one or two fabrics on each other while interposing a piece of a synthetic polymeric bonding tape between the superposed two end portions and by applying a high frequency wave treatment and/or heat treatment to the interposed portion of the bonding tape through at least one of the superposed end portions while pressing them, to melt the interposed portion of the bonding tape thereby lap welding the end portions of the fabric or fabrics to each other.
