FIG. 5 is a perspective view illustrating a pair of upper mold parts according to the present invention. FIG. 6 is a state diagram showing the use of the upper mold part and the lower mold part according to the present invention, 8 is a view illustrating a state in which the upper mold part moves downward and is in close contact with the lower mold part according to the present invention, And the roller bending section is operated.

5 to 8, the upper mold part 300 is arranged in a bar shape along the longitudinal direction of the front end of the panel P to be conveyed along the conveying platform 100, and operates in the vertical direction A cutout groove 310 is formed in the concave and convex type along the conveying direction of the conveying table 100 so that the folded portions P1 and P2 on both sides of the panel P bent by the side folding means 200 pass therethrough And the bottom surface of the front and rear ends of the panel P are closely contacted with the top surface of the panel P.

At this time, it is preferable that a plurality of cutting grooves 310 are formed at predetermined intervals along the longitudinal direction of the upper mold part 300. 7, one incision groove 310 (the leftmost in FIG. 7) is formed on one side of the bottom surface of the upper mold part 300, and a plurality of incision grooves 310 (310) to be compatible with the width dimension of the panel (P).

Since the width dimension of the panel P is specified for each type, if a plurality of cut-out grooves 310 are formed in advance on the bottom surface of the upper mold part 300, it can be compatible with various kinds of panels P There is an advantage.

4 and 8, the upper mold part 300 is arranged in a pair so as to correspond to the front and rear of the panel P, To press the rear upper surface and the front upper surface of the panel P at the same time.

Here, the control unit may be configured such that the pair of upper mold parts 300 press-control the front and rear upper surfaces of the panel P at the same time.
