Abstract

An apparatus for the production of hollow products characterized by: (A) a sliding mold (6), the cavity (5) of which is in the shape of the product to be manufactured, (B) an annular extrusion hole (11) located within the cavity (5) of the mold (6) and whose transverse surface is convergent in the extrusion direction, (C) a mechanism (3, 4, 15, 28, 29) to extrude inside the mold (6) the block (1) with one end open in front through the annular extrusion hole (11), (D) means (14) in the mold to receive the extruded block (11) and form and retain an annular flange of the extrudate at one end of the mold cavity (5), (E) a mechanism (35, 7) to slide the mold (6) from one position to a second position relative to the extrusion hole 11 while the block (1) is continuously extruded and stretch the extruded block into the mold forming a hollow hull (17) and (F) means (52, 53, 56, 7, 8, 9, 10) for introducing a fluid into the hollow shell during extrusion of the block to expand the hollow shell (17) until it abuts against the inner wall of the mold cavity (5).
