Abstract:
A resin-coated high-tension flat steel wire includes a high-tension flat steel wire and a fiber-reinforced polyamide resin coated layer. A shape of the high-tension flat steel wire when viewed from a section perpendicular to a longitudinal direction thereof is a rectangular shape including curved portions at four comers thereof. When, among four straight lines that form the rectangular section, the ranges from both end points of the straight lines that form long sides to one fourth of the length of the straight lines are respectively defined as one-fourth segments, a shape of the fiber-reinforced polyamide resin coated layer in the rectangular section includes a mountain shape having an apex within each of the one-fourth segments, and includes a minimum point, where the thickness of the fiber-reinforced polyamide resin coated layer is the minimum, between the apex and both the ends within each of the one-fourth segments.

Abstract:
Provided are a rubber article reinforcing steel wire that is superior in bending fatigue properties to the related art and has a flat cross-sectional shape, and a rubber article using the wire. In a rubber article reinforcing steel wire 10, a major diameter and a minor diameter are substantially perpendicular to each other. Assuming that the major diameter is W, the minor diameter is T, a straight line that passes through a center of the major diameter in a width direction and is parallel to a minor diameter direction is L1, a straight line that passes through a center of the minor diameter in a width direction and is parallel to a major diameter direction is L2, an intersection point of the L1 and the L2 is a center point C, a region within a half of a distance from the center point C to a surface is a central region Rc, and a region outside the central region Rc is a surface layer region Rs, a Vickers hardness Hvc of the central region Rc is more than a Vickers hardness Hvs of the surface layer region Rs; and assuming that a Vickers hardness on the L1 in the surface layer region Rs is Hv1, and a Vickers hardness on the L2 in the surface layer region Rs is Hv2, relationships represented by Hvc - Hv1 ≤ 150, Hvc - Hv2 ≤ 150, Hv1/Hvc × 100 ≥ 85.11, and Hv2/Hvc × 100 ≥ 79.84 are satisfied.
Abstract:
The invention relates to an endless shaped article comprising at least one strip of material forming a plurality of convolutions of the strip of material, the strip having a longitudinal axis, wherein each convolution of said strip comprises a twist along the longitudinal axis of said strip, wherein said twist is an odd multiple of 180 degrees. The invention also relates to a method to manufacture said article, and its use as sling, loop, belt or chain link.
Abstract:
The invention is directed to materials comprising polylactic acid (PLA). In accordance with the invention, PLA material is stretched in at least the machine direction at a total stretch ratio of 1:4 or more. These materials have excellent biodegradability and find use in horticulture, in particular for tying up plants or parts thereof.
Abstract:
Die Erfindung bezieht sich auf temperaturbeständiges, elastisches Strangelement (10), insbesondere in Form eines Profilbandes(11), einer Kordel, einer Litze oder einer Rundschnur. Das Strangelement (10) besitzt für erhöhte Anforderungen im Bereich Automotive insbesondere eine Dauerelastizität in einem weiten Temperaturbereich von -40°C bis 120°C. Ein solches Strangelement (10) umfasst mindestens einen Mantel (20), der eine in Längsrichtung des Strangelements (10) verlaufende strangförmige Seele (30) aus Silikonmaterial umgibt, wobei vorzugsweise ein oder mehrere textile Lagen den Mantel (20) bilden und die einzelnen Lagen aus einem Geflecht, einem Gewebe (22) oder einem Gewirk bestehen und diese Lagen die Seele (30) in Längsrichtung vollständig umgeben (Fig.1a).
Abstract:
The invention relates to a multilayered material sheet comprising a consolidated stack of unidirectional monolayers of drawn polymer. The draw direction of two subsequent monolayers in the stack differs. Moreover the strength to thickness ratio of at least one monolayer is larger than 4.5.1013 N/m3. The invention also relates to a ballistic resistant article comprising the multilayered material sheet and to a process for the preparation of the ballistic resistant article.
Abstract:
Method for making a cable, particularly a so called armored cable, comprising following steps: A- providing a rope (3) constituting the core of said armored cable B- providing at least an armor winding band-like member (1)
wherein said armor winding band-like member is a so called preformed band (2) i.e. bent substantially about the longitudinal axis of the band and/or an axis parallel to the axis of longitudinal development of the band, and comprising in addition the step of D- covering said rope by winding at least one, preferably two, preformed bands (2) such that the concave region of the bend of said preformed band is faced towards the rope.
