gear wheel of plane and have roller gear wheel clench the teeth, make panel for one and offer the torsion; Make the roller and make vertical sports of hoisting or lower, the hydraulic oil in the hydraulic pressure jar acts on the piston and gets, in order to clamp the panel, it is the hydraulic transmission; On the bottom there are side rollers and do sports of inclining along the framework guide on both sides of the roller, pass the mother's worm gear worm transmission of pole silk of silk; This machine advantage is that a panel tip is curved in advance and a round can go on on the same equipment.
