Device for cutting extruded plastic profiles to length
A device for cutting a preferably thick-walled, extended pipe to length, has at least one cutting tool and a receiving unit for the cutting tool. The cutting tool is radially movable in relation to the extrusion axis and is rotatable via further means about the pipe to be cut to length, in order to cut the pipe to length. The receiving unit may be connected by means of a receiving disc to a sleeve via a ring element, wherein linear guiding elements are arranged on said sleeve parallel to the extrusion axis, and wherein at least four linear guiding elements are evenly distributed around the circumference of the sleeve.
Method for molding tailored composites
In at least one embodiment, a molding method for producing a molded article is provided. The method may include introducing polymer and fiber separately into an extruder in a first ratio to produce a first extruded material having a first fiber content and in a second ratio to produce a second extruded material having a second fiber content different from the first fiber content. The method may further include filling a first region of a mold with the first extruded material and a second region of the mold with the second extruded material. The extruded material may be formed as blanks for use in compression molding or may be introduced into an injection chamber for use in injection molding. The method may be used to form molded articles having a plurality of regions having different fiber contents.
Method of making a flexible magnetized sheet
A method of making a flexible magnetized sheet is provided. The method may comprise the steps of (1) using cold extrusion to produce a highly viscous fluid magnetizable sheet, (2) passing the sheet through a magnetic field to create an uncured magnetized sheet, and (3) curing the sheet with electron beam curing. The fluid mixture may comprise magnetizable particles with a random charge orientation and an acrylic resin. The components of the mixture are cool when passed through an extrusion die. The extruded fluid sheet allows for the sheet to be magnetized and then, instead of curing by cooling, cured by the bombardment of electrons via an electron beam (EB) generator. The method can eliminate the heat of extrusion and can allow for more freedom of orientation because the sheet does not cure until it reaches the electron beam curing station.
FLOORING COMPONENT
A flooring component comprising a main body portion defining a first major surface and a second major surface, a first extending portion that extends from the main body portion in a first direction, the first extending portion defining a third surface coplanar to at least a portion of the first major surface, and a second extending portion that extends from the main body portion in a second direction opposite the first direction, the second extending portion defining a fourth surface coplanar to at least a portion of the second major surface, wherein at least 60% of the main body portion, the first extending portion and the second extending portion is of a first material, the first extending portion comprises a female structure on a side of the first extending portion opposite the third surface, the second extending portion comprises a male structure on a side of the second extending portion opposite the fourth surface, the flooring component comprises, in a region of at least one of the female structure and the male structure, a resilient portion of a second material more pliable than the first material, and the female structure is of a shape that snappingly engages the male structure using a resilience of the resilient portion.
RINGED TUBULAR SHEATH HAVING A DETACHABLE LONGITUDINAL STRIP
The invention relates to a ringed tubular sheath which comprises a longitudinal strip which can be easily detached by a user, in particular manually. More specifically, the invention relates to a ringed tubular sheath comprising a sheath body (1) and a longitudinal strip (6) which are made of materials that substantially do not adhere to one another, the longitudinal strip (6) comprising, on each of its longitudinal sides, an upper projection (2, 8) and a lower projection (3, 9), between which a respective longitudinal edge (5, 7) of the sheath body (1) is fitted, this sheath being distinctive in that the longitudinal strip (6) is substantially in the shape of an arc of a ringed tube. The invention also relates to a manufacturing method and to the use of such a sheath.

Embodiments of an invention disclosed herein relate to devices, processes, and systems for processing polymers.
EXTRUSION TOOLING AND PROCESS FOR BIODEGRADABLE COMPONENT
An example extrusion system includes a die including a circular cross-section disposed about an axis, and a plurality of slits disposed in the die and circumferentially spaced about a periphery of the die. Each of the plurality of slits has a generally rectangular cross-section. A ratio of a number of slits comprising the plurality of slits to a distance between the plurality of slits is between approximately 144:1 and 96:1. A method of forming a biodegradable component with an extrusion system is also disclosed.
SOUND ABSORBING BODY
A sound absorbing body comprises a non-woven fabric or a non-woven fabric laminate, the non-woven fabric or the non-woven fabric laminate comprises a fiber that has an average fiber diameter of less than 3,000 nm, the non-woven fabric or the non-woven fabric laminate has a thickness of less than 10 mm, the non-woven fabric or the non-woven fabric laminate has a unit thickness flow resistance of greater than 4.0 E+06 Ns/m.sup.4 and less than 5.0 E+08 Ns/m.sup.4, and the non-woven fabric or the non-woven fabric laminate has a bulk density of greater than 70 kg/m.sup.3 and less than 750 kg/m.sup.3.
Biaxially Stretched Porous Film
A film that comprises a thermoplastic composition that contains a continuous phase that includes a polyolefin matrix polymer and a nanoinclusion additive dispersed within the continuous phase in the form of discrete domains is provided. The film is biaxially stretched in a machine direction and cross-machine direction to form a porous network in the composition. The porous network contains nanopores having a maximum cross-sectional dimension of about 800 nanometers or less. At least a portion of the nanopores are oriented in the cross-machine direction so that the axial dimension generally extends in the cross-machine direction and the cross-sectional dimension generally extends in the machine direction.
MEDICAL DEVICE
A medical device having an imaging function includes a shaft main body portion having an image acquiring lumen and a guide wire lumen extending from a distal side to a proximal side of the shaft main body portion. A proximal portion of the shaft main body includes a first shaft proximal portion in which the image acquiring lumen is disposed, and a second shaft proximal portion in which the guide wire lumen is disposed, and which are bifurcated. A shaft distal portion has a common lumen in which the image acquiring lumen and the guide wire lumen converge, a first hub portion is interlocked with the first shaft proximal portion, a second hub portion is interlocked with the second shaft proximal portion, and a hub casing collectively covers the first shaft proximal portion, the second shaft proximal portion, the first hub portion and the second hub portion.
