whose role is to weld two geomembranes into one, just like welding two metal plates into one.
1. Electric heating system: The heating temperature of electric heating wedge adopt closed-loop temperature control for continuous adjustment weld via adjusting corresponding pressure position according to the material thickness 2. Welding pressure regulation system: for continuous adjustment 3. The transmission system : Using compression roller dual wheel synchronously drive power level variable speed control self-control system matches with tachogenerator to adjust welding speed and keep constant, which is affected by load change through three-level planetary gear reduction transmitting force to the pass / pressure roller
