PURPOSE:To manufacture an annular stock body for forming a synthetic resin molded article with good workability. CONSTITUTION:Stock fabric, which is prepared by infiltrating phenolic resin in cotton woven fabric and, after that, drying, is cut rectangularly or square. The resultant stock fabric is rolled up in a rod about an axis, which makes the predetermined angle to one side of the square or rectangle. The obtained rod-like body 2 is made into an annulus in order to turn into an annular stock body 3 by piling up both the ends of the rod-like body 2. |
