Rolled coned manufacturing apparatus
First Claim
1. A rolled cone manufacturing apparatus, comprising:
- a concave half and a convex half which form a cavity inside when combined with each other, a cross section of the cavity having a circular shape in a direction orthogonal to axes of the concave half and the convex half; and
supporting means which rotatably supports the convex half, on condition that the axis of the concave half is aligned with the axis of the convex half, said supporting means being openable and closable, and pushing, on at least three points that are spaced apart from the cavity, an outer periphery of a part of the convex half protruding from the concave half onto the axis, when said supporting means is closed.

Abstract
A concave half (10) having a conical inside and a convex half (20) having a conical outside and being fitted therein are fitted in each other. An openable and closable, loop-shaped supporting means as a toggle-jointed link (30) rotatably supports and pushes a cylindrical part (23) of the convex half (20) onto the axis on at least three points on the outer periphery of the cylindrical part (23), with an axis of the concave half (10) and an axis of the convex half (20) being aligned with each other when the supporting means is closed. The toggle-jointed link (30) is openable and closable, wherein a plurality of rolling objects such as rollers (31) are provided inside the loop, thereby improving function as a bearing of the supporting means and efficiently manufacturing quality rolled cones (40).

11. A rolled cone manufacturing apparatus, comprising:
-
a concave half and a convex half which form a cavity inside when combined with each other, a cross section of the cavity having a circular shape in a direction orthogonal to axes of the concave half and the convex half; and supporting means which rotatably supports the convex half, on condition that the axis of the concave half is aligned with the axis of the convex half, said supporting means being openable and closable, and pushing, on at least three points, an outer periphery of a part of the convex half protruding from the concave half onto the axis, when said supporting means is closed, wherein the supporting means is a loop-shaped member which is openable and closable, and the supporting means includes, provided that a part where the loop of the supporting means is cut off is referred to as a split part, a positioning and fixing member for positioning and fixing the split part in place, when the supporting means is closed, said positioning and fixing member serving as a guiding member when the material sheet is brought into the concave half.
