Title: Method and apparatus for transporting plastics in a melted state

Abstract: A method and apparatus is provided to transport parisons from the extrusion die to a second location. The parison is extruded and a collar means is provided to contact the parison near its upper end and create a holding geometry whereby the parison is retained by the collar means without pinching the parison. The parison is then transported vertically or horizontally to the mold unit without closing or pinching the parison. The holding geometry is created by slightly deforming the parison wall near the collar means. The parison is therefore transported to the second location, for example a mold unit, instead of moving the mold unit, to the parison.
