METHOD AND SYSTEM FOR CLAMPING METAL FRAMES OF WIRE OR STEEL STRIP ONTO THE EDGES OF MATTRESS SPRING UNITS MADE OF SPRINGS, WHICH ARE CONNECTED TO EACH OTHER BY MEANS OF WIRE, SPIRAL OR ARE POCKETED IN CLOTH OR NON-WOVEN

摘要

This invention refers to a method and a system for the fastening of wire or strip steel(1), (2) onto the outer side of the springs (3), which form the edges of an innerspring unit with metal clamps (4), where the springs are connected too each other with a metal spiral or are pocketed in cloth or non woven, which fastening is achieved by a number of presses equal to the number of springs we want to fasten and which presses are actuated simultaneously or gradually.
