The invention is a method of producing a product with a symmetrical and constant cross-section, for example rackets, ice hockey sticks, etc. These can be formed with the aid of two reversed cavities in which a rawling consisting of a porous core surrounded by reinforced hard plastic is situated.The invention is intended to strengthen the connection between the two rawlings. This is achieved by virtue of the cavity sections including a semi-circular surface with diameter D and a rectangular surface with sides D and larger than D/4 but smaller than D/2. The outer surface of the rawlings is approximately equal to D.<IMAGE> |
