BINDING FRAME FEEDING DEVICE

PROBLEM TO BE SOLVED: To provide a new binding frame feeding device that manufactures and feeds a binding frame for binding a calendar pamphlet.SOLUTION: A pair of forming rollers 122 and 123 are arranged so that a part of outer circumferential surfaces face to each other and a paper board 121 can pass through a space between the outer circumferential surfaces. On the outer circumferential surface of one roller 122, a convex ring 124a is formed. On the outer circumferential surface of the other roller 123, a concave ring is formed corresponding to the convex ring 124a. When the paper board 121 passes through between the pair of forming rollers 122 and 123, the paper board 121 is held between the convex ring 124 and the concave ring to form a folding part 125 that can be folded for folding the paper board in half, and the binding frame 14 is formed by the paper board 121.
