Abstract: A blowing head, a method for producing a blown film, and a blown film installation include the use of plate spiral distributors in blown film installations for distributing melt steams arriving from extruders and for combining the melt streams to form an annular gap stream in several layers in an annular gap leading to a tubular die. The melt streams in a plate spiral distributor are initially bundled and then forwarded in a bundled manner to a common co-extrusion flow. The distributer has a plurality of spirals in superimposed layers, and the spirals of two layers have a junction for pre-combining the melt streams of two layers, and in that starting from the junction, a common guide leading to the annular gap is provided for combining there the pre-combined melt streams with the annular gap stream.

Abstract: Disclosed apparatus and method to extrude a honeycomb, providing correction in bowing of the extruded honeycomb structure, employs a deflector device having a base plate including an opening aligned in a direction parallel to the extrusion axis through which the plastic material is conveyed to the die. The deflector device includes a bow plate movably mounted to the downstream or upstream side of the base plate. The bow plate includes a constant area aperture. The deflector device positioned upstream of extrusion die imparts a degree of bow reduction by the position of the constant area aperture over the opening imparting a pressure drop gradient on the flow stream entering the die.

Abstract: The invention is directed to a crosshead die for the extrusion of a profile, such as a uniform ply coat for a tire. The crosshead die is used with an extruder, and includes a body. An inlet is formed in the body, and is in fluid communication with the extruder. An outlet and a flow channel are also formed in the body. The flow channel extends between the inlet and the outlet, and is bounded by an upper wall, a lower wall, a first side wall, and a second side wall. The flow channel is formed with a bend and a cross section that includes a trapezoidal shape to align the flow of elastomer with the center of the flow channel.

Abstract: A device for producing plastic pipes may include an extruder with a die head and a corrugator, into which a molten plastic tube is introduced by means of the die head to mold the plastic pipe, wherein the corrugator has a molding section, in which molding jaws are guided in pairs in the production direction. In an inlet section of the corrugator, the molding jaws are brought together to form molding jaw pairs towards the start of the molding section, and in an outlet section of the corrugator, the molding jaw pairs are moved apart from each other from the end of the molding section. The guiding apparatus has a guide and/or temperature-control element apparatus having a temperature-control medium channel apparatus through which temperature-control medium can flow, and a guide and/or temperature-control surface apparatus, which faces the outer side of the molding jaws passing through, transferring heat.
