摘要： The present disclosure provides an apparatus and methods for producing co-extruded composite webs including a continuous layer of an extruded matrix material, and a multiplicity of included phases embedded in the continuous layer. The included phases are surrounded by the matrix material to form a single-layer composite web within a feed block having an internal die body. The included phases are separate from each other by being discontinuous in the cross-web direction, but the included phases may be substantially continuous in the down-web direction. In some exemplary embodiments, the co-extruded single-layer composite web may be used in a single-layer or multi-layer article. In other exemplary embodiments, the single-layer co-extruded composite web may be in the form of a sheet, a film, a blown film, a filament, a fiber, a tube, and the like.

Each cross section of the drawing path (and, hence, polymer composition in the drawing path) is non-circular, substantially proportional to one another, contains a centroid that lies on a substantially straight line parallel to the drawing direction and all cross sectional dimensions are 1.5 millimeters or more.

摘要： A co-extrusion head for forming high-aspect ratio gridline structures in a micro extrusion apparatus includes multiple sheets (e.g., metal plates) that are machined and assembled to define three-part fluidic channels having associated outlet orifice disposed along an edge surface of the head. Reference surfaces are also etched in the sheets and are aligned in a straight line that intersects output junctions of the three-channel cavities. After assembly (e.g., using high pressure bonding techniques), each reference surface is located inside a notch defined in the edge surface. The edge surface of the co-extrusion head is then trimmed (e.g., machined by wire EDM) using the reference surfaces as a precise guide, thereby producing uniform length outlet orifices with uniform flow impedance.

摘要： The invention relates to a device for the production of multi-layer, co-extruded, tubular pre-forms made from thermoplastic plastic. A co-extrusion head (10) comprises co-axially arranged flow channels (FK1, FK2), each supplied by a single inlet opening (ZF1, ZF2) with a material melt, distributed annularly in a distribution ring (26, 28). The gap width in each distribution ring (26, 28) is greater in the vicinity of the inlet opening (ZF1, ZF2) than the gap width (s2, s6) in the region of the side opposing the inlet opening (ZF1, ZF2). The flow channels (FK1, FK2) are also asymmetric with regard to the gap widths.

摘要： A melt distribution block for a co-extrusion die has a generally annular body with opposed front and rear faces and opposed inner and outer faces. Inlets at the outer face have channel ports for accepting flow of melted polymer into the distribution block. Flow controlling valves independently control the melted polymer flow through each of the channel ports. Melt flow channels on the front and rear faces between the inner and outer faces are in fluid communication with the channel ports. A thermal insulation layer within the distribution block between the front and rear faces separate all or part of the melt flow channels on the front face from all or part of the melt flow channels on the rear face. The blocks, together with separator blocks, are axially stackable front to rear around a central mandrel to form an extrusion die for making blown films into tubular form.

摘要： A continuous process for producing oriented plastic tube is disclosed having the steps of extrusion (12) of a tube to an initial extruded diameter, temperature conditioning (18), diametrical expansion (20) and cooling (30), characterised by control of the circumferential draw ratio by the step of adjusting the diameter of the extruded tube to an adjusted diameter by means of a variable diameter calibrator (13) located between said extrusion and temperature conditioning steps. A process line for carrying out the invention is also disclosed. Further embodiments of the invention include adjustment of the extruded wall thickness and compensatory adjustment of the adjusted diameter so as to effect a change in final wall thickness with unchanged draw ratio, a process for changing final product diameter and a start-up procedure for the process.
