Abstract
Abstract A high frequency heating machine for laminating fabric material in which a heating electrode for each side of the material is divided into two parts and in which each of the four electrodes is preheated, the two electrodes on one side of the material dividing the load and having capacitors therebetween. Mechanism is provided for step-by-step passage of the material between the two opposing sets of electrodes in which the dies are spaced three times the effective width of one die and in which the stroke of the material for each step is twice the effective width of one die.
