A drive for a heating unit for welding plastic sealing and film material, comprises a heater for warming the plastic. A drive for a heating unit for welding plastic sealing and film material, comprises a heater for warming the plastic. A longitudinal housing (6) has a press and drive roller (9) at its lower end, and force is applied to the seam in the vertical direction. A motor is located in the housing , to drive the roller, and a coupling unit (7) connects the housing to the heater (1) so the longitudinal axes (16,17) of the housing and the heater are parallel to each other. The roller can be adjusted with respect to the heating unit, in terms of height and spacing, and a guide reduces the roller tilt during welding. The angle between overlapping edges and the roller can be adjusted. |
