SUNPASS Large winding machine is a horizontal large winding machine that can produce wound gaskets with or without inner rings, and its production diameter is between 300MM-2500MM or 3200MM. Driven by a variable frequency controlled gear motor. The inner ring or spacer core is supported by the guide wheel and driven by the main wheel to slide on the horizontal table, and at the same time the steel belt and the filling are wound. The number of welding points and the displacement of the angle can be pre-set in the control data. Welding power can also be freely controlled. Through the operation of pedals and buttons, the rotation of the ring is controlled and spot welding is performed. Regardless of whether the filler is graphite, PTFE, non-asbestos, or other materials. Just by adjusting the air pressure and the position of the pressure roller, the tightness and flatness of the gasket can be controlled.
