ABSTRACT:
A method of the device for producing a hollow columnar piece whereby a blend of essentially thermoplastic particles is melted into a billet, introduced into a mold, looped into layers inside the mold, and transformed into a piece, subsequent to which the piece is solidified by cooling and removed. The billet (3) is rotated around its axis and concentric with its face as it is introduced into a mold (4), the mold accommodates a core (20), space is left between the core and the inner surface (6) of the mold, the billet is laid along the circumference of the space, and the billet continues to be introduced into the space until the mold's inner surface and core are uniformly and continuously wet with constituents of the billet.
