Three-dimensional polymeric strand netting described herein have a variety of uses, including wound care, tapes, filtration, absorbent articles, pest control articles, geotextile applications, water/vapor management in clothing, reinforcement for nonwoven articles, self bulking articles, floor coverings, grip supports, athletic articles, and pattern coated adhesives.

To provide a method for producing a fluororesin film, whereby defects due to deterioration (such as fish-eyes due to gelation) of a melt-processable fluororesin are less likely to occur during the production. A method for producing a fluororesin film, which comprises extruding a fluororesin material containing a melt-processable fluororesin through an extruder die, wherein the temperature of the extruder die is from 305 to 355 C., and the average flow velocity v.sub.0.95 of the fluororesin material as obtained by v.sub.0.95=Q.sub.0.95/A.sub.0.95, is at least 110.sup.4 m/sec. Here, when the distance from the flow inlet 22 of the extruder die to the end of the manifold 24 of the extruder die is set to be x=1, Q.sub.0.95 is the flow rate (m.sup.3/sec) of the fluororesin material flowing in the manifold 24 at a position of x=0.95 from the flow inlet 22, and A.sub.0.95 is the cross-sectional area (m.sup.2) of the manifold 24 at a position of x=0.95 from the flow inlet 22.

A nozzle for extruding a composite material from an extruder barrel. The nozzle includes a body and a tapered nozzle passage extending through the body. The tapered nozzle passage having a nozzle inlet opening configured to interface with the extruder barrel, and a nozzle outlet opening, where the tapered nozzle passage has a contoured nozzle passage surface extending between the extruder barrel and the nozzle outlet opening with smooth transitions, free of angles, so that each nozzle passage surface portion, having a corresponding contour, transitions smoothly to each other nozzle passage surface portion, having a respective different contour, from the nozzle inlet opening to the nozzle outlet opening, and the nozzle outlet opening is defined by at least a first edge and a second edge that intersect each other at an acute angle.

Extruded seals including a sealing portion with a honeycomb profile and method for making extruded seals with honeycomb profiles. An extrusion tool is provided with a first and second plate connected together. The first plate has a plurality of pins, which are vented to form a honeycomb profile. The second plate has a profiled opening receiving the plurality of pins and forming the overall shape of the part, including the outermost surfaces of the part. The pins serve as mandrels for extruded molten material to flow around. Varying the pin configuration and dimensions changes the honeycomb profile. The honeycomb structure is provided in the sealing portion of the extrusion. The honeycomb profile is formed by itself, co-extruded with a rigid or semi-rigid structural member, or applied to the rigid or semi-rigid structural member after the structural member is formed.

A method of producing a part printed in a layer-wise manner includes providing a pre-fabricated starter piece with a first course of loops and printing a layer of a part by extruding one or more flowable thermoplastic materials about the existing course of loops such that an upper surface of the layer is at a selected height on the existing course of loops. The method includes knitting a next course of loops to the existing course of loops to form a portion of an internal woven reinforcement network, and printing a next layer of the part by extruding one or more flowable thermoplastic materials about the next course of loops such that an upper surface of the next layer is at a selected height on the next course of loops, wherein the next course of loops extends above the structure being printed and may function as an existing course of loops for subsequent knitting steps. The method includes repeating the knitting and printing steps to create an internal woven reinforcement network within the printed part until the part is completed. The starter piece and the course of loops extending from the second end of the completed part are engaged and heated to a temperature where the material is flowable. The reinforcement network is then placed into tension by applying a force to pull the starter piece and the course of loops in opposite directions from each other. The part is cooled to a temperature where the thermoplastic material solidifies such that the internal woven structure remains in tension.
