Operations of Melion Envelope Spreader
Before wrapping the envelope, it shall be put on the Holding Pads of the Spreading Arms. Operate the air cylinder and drive the Spreading Arms outwards to spread the Envelope. Then open the Gripper and grip the rim, and then lift the tire up with the cylinder-driven cable wire and guiding pulley. Rotate the lifting arm and lower the tire into the center of the Spreading Arms, and then put it into the envelope. Manipulate the Air Cylinder to retrieve the Spreading Arms and release the Spreading Pads off the Envelope. Then lift the tire out of the Spreader. By then, enveloping is completed. De-enveloping is the inverse process of enveloping.
