Method for operating a welding device, in particular a heat pulse-controlled and / or permanently heated foil welding and / or heat-sealing device with preselectable electronic, processor-controlled contact pressure and temperature control and device for this purpose

摘要

Method for operating a welding device (100) for welding heat-sealable materials, in particular films, preferably plastic films in tubular and / or bag form and / or other weldable materials (eg internally coated aluminum and / or paper composite film) , comprising a first movable heating tape carrier (10) carrying a heating element, and in particular a second immovable heating tape carrier (11) on which an element, in particular a second heating element or an unheated element is arranged, wherein the first movable heating tape carrier (10) by a drive of at least one positioning unit (12) between an open position and a welding position is movable and running the positioning unit via at least one stepper motor and / or a hydraulic drive and / or a pneumatic drive and / or electric and / or linear motors, such as DC or AC motors with brushes or brushes enlose motors is carried out, wherein on the lower Heizbandträger arranged pressure sensors (23, 24) for monitoring the movement between the open position and the welding position are present, characterized in that the pressure sensors (23, 24) with a monitoring control (S) are connected and to this output one or more signals when a non-permissible operation is present, wherein the non-permissible operation is a blockade of the movable strip heater (10), that the movable strip heater (10) automatically in a zero position (NP) and / or in the open position retracts when the non-permissible operation is present and that for determining the permissible operation a contact pressure measurement is carried out, and that in impermissible operation, the pressure sensors (23, 24) detect a pressure increase within the travel path between the open position and welding position.
