As such, the cooling time depends on the The insulating layer 8 can consist of a ceramic thermal conductivity and the thickness of the mass to be penetrated. For welding low layers. It is a multiple of the 40 foils or heat-sealable in the material or the corresponding heating time and essentially determines the correspondingly coated paper. ren 10 with an inside diameter of 1.5 to With these known heat impulse welding process 6 min, primarily 2 to 5 mm, and wall thickness directions, therefore, primarily only thin directions of 0.1 to 1 mm can be advantageous,
and weld the thinnest foils. In general, high speeds are possible when setting up an entire filing according to the heating and cooling speeds, but in Fig. 3, the welding jaw 5 carries one or more; Time of welding time to complete. Electricity is also supplied. In the electrically non-conductive, the highly stressed parts such as the heating tape, hoses or tubes 13, the coolant zudeckfolicn etc. is consumed and must therefore be discharged from 50 or. The control of the coolant flow must be renewed from time to time. takes place through a suitable control valve, e.g. B. by Besides it is also known to use a solenoid valve 14 in the welding device. In the position shown, this valve 14 is set to "cooling" for heat-sealable materials. If the coil of welding jaws is flowed through by a heating medium 15 with electrical current flowing through it, then it can be lifted. 55 of the valve tappet 16. Thereby it blocks the inflow. Starting from this usual pulse welding via the line 13 to the welding tube 10 advise against with an electrically heatable welding inlet and gives the direct outflow to an intent, the application is based on the task of the storage tank 17 free. This storage container 17 is filled with a coolant in the case of the cycle time consisting of the heating-up time and the cooling-down time, and must be shortened in order to produce a weld seam. 60 the coolant circulation is generated by the pump 18 Zur Lösung dieser Aufgabe, besteht die Erfindung möglicht.To solve this problem, the invention is possible. darin, daß der Schweißeinsatz dünnwandig und hohl Es besteht auch die Möglichkeit, an Stelle derthat the welding insert is thin-walled and hollow.
