Abstract: An extrusion die is provided with an adjustable end seal assembly. The extrusion die includes a die body, and the adjustable end seal assembly includes an end seal device and a wedge mechanism. The adjustable end seal assembly has an engaged configuration and a disengaged configuration. When in the engaged configuration, the adjustable end seal assembly is held forcibly against the die body. When in the disengaged configuration, the adjustable end seal assembly is either spaced apart from the die body or held against the die body with less force than when in the engaged configuration. Methods of operating such an extrusion die are also provided.

Abstract: An extrusion nozzle for making tubular preforms has a mandrel extending along a vertical axis, an annular and stationary nozzle body spacedly radially surrounding the mandrel, and a holding ring having an upper end axially slidable in the nozzle body, braced axially downwardly against the nozzle body, and having a lower end spaced radially inward from shiftable limitedly radially relative to the nozzle body. A nozzle ring has an upper end axially slidable in the holding ring, is braced axially downwardly against the nozzle body, and has a radially deflectable lower end forming an annular extrusion gap with the mandrel. A first positioner engages the lower end of nozzle ring and is operable to radially deflect this lower end. A second positioner engages radially with the lower end of the holding ring or with the nozzle ring for radially deflecting same.

Abstract: A device for producing pipes made of thermoplastic with annular transverse profilings with a cross section in the form of undulation peaks and undulation troughs has half-molds, which complete one another pairwise along a straight mold section to form a closed mold, which can be moved in a movement direction. Projecting into the mold is an extrusion tool, which has a nozzle support body. To produce an adequate seal between the half-molds and nozzle support body, the latter is covered with exchangeably attached hollow half-shells, which form a cylindrical external face.

Abstract: The invention relates to a feed roll assembly for reducing leakage of an elastomeric material in a feed section of an extruder machine. A shell, feed roll seal plates, and feed roll end plates are used to reduce the leakage of elastomeric material. Elastomeric material is redirected back to the feed section through the use of a varying bore diameter of the shell and grooves contained in both the feed roll seal plates and the feed roll end plates. The shell, feed roll seal plates, feed roll end plates, and a feed roll scraper are each coated with a solid, dry lubricant coating to reduce friction. The invention provides desirable feedback of overflow elastomeric material and permits a retrofitting of the feed roll assembly to existing extruder machines.

Abstract: An extrusion method and head for depositing by extrusion a polymeric material intended, in particular, for the production of cables includes a core and a coating layer arranged at a radially outer position with respect of the core. The method includes the steps of feeding the polymeric material in a feeding duct of the extrusion head and of conveying a part of the polymeric material towards an undercut extending in the extrusion head in proximity of an end of the feeding duct. The method provides a sealing force between a head body and a conveyor element of the extrusion head exerted by means of the pushing action exerted by the polymeric material in the undercut in a direction substantially perpendicular to the longitudinal axis of the head body.

Abstract: A method for removing volatile components from wet, polymer powders using a vacuum vented extruder is described. Polymer powders containing substantial amounts of water, 1-20% by weight, are rapidly converted to polymer compositions containing less than about 0.5% by weight water at high throughput rates while avoiding complications resulting from excessive steam backflow through the extruder feed throat. The method provides a screw design comprising a powder seal section upstream of kneading and melting sections of the extruder. Steam generated as the polymer is heated flows downstream to one or more vacuum vents for removal. The partially devolatilized polymer melt is then subjected to additional melt kneading and vacuum venting. The method converts wet polycarbonate powder containing residual methylene chloride to essentially dry polycarbonate powder containing less than about 1 ppm methylene chloride.
