Abstract

1,262,398. Seaming non-metallic sheet material. G. M. PFAFF A.G. 18 March, 1970 [19 March, 1969], No. 13112/70. Heading B5K. A high-frequency electrical generator 1 may be connected, selectively, by a change-over switch 8 to either one of two high-frequency welding devices. As shown, the generator 1 is connected, through the interposition of an impedance matching device 6, to a stationary high-frequency welding machine having a displaceable welding tool 4 and a work-table 5. By actuating the switch 8, the generator 1 can be connected to a hand welding device 7 comprising electrodes 11, 12.
