Hand-operated appliance for cross-welding plastics material tubes filled with liq. - has squeezing unit for tube with fixed and moving jaws and welding unit with two electrodes lying opposite each other reaching in tube reception part

摘要

The pressure jaws are of the vice type and laterally define the tube reception part (15). The moving joint moves horizontally. One electrode (8) is fixed at the carrier (18) and the other electrode (2) is located movable in a pressure jaw (3) in the direction of the tube and is preloaded by a spring (4). A separation unit is provided designed as a cutting edge (19), which is arranged at the electrode (8). An operating lever is rotationally located at the carrier, which works in conjunction with a pressure jaw and an electrode across a slider, and activates an electric switch arranged in the housing. A screening unit (21) is arranged movable in the region of the tube reception part (15). The screening unit works in conjunction with the pressure jaw (3). ADVANTAGE - Prevents occurrence of radio frequency interference radiation in region of tube reception part.
