Method for high speed stranding of aramid yarns
A method for stranding aramid yarn around an endless core includes a stranding step that involves a stranding apparatus having at least one yarn bobbin. The bobbin revolves around its own axis and the bobbin revolves around the core, wherein the yarn unwinds from the bobbin and winds around the core. The yarn is a continuous aramid yarn provided with 0.05 to 0.95 wt %, based on the weight of the aramid, of a finish including an organophosphorus compound. The organophosphorus compound is a compound of the formula X1X2X3P═O. X1, X2, and X3 are independently selected from Y1-, Y1-O—, and M-O. Y1 is a branched or straight-chain C1-C20 alkyl, aryl or alkenyl. M is selected from Li, Na, K, or ammonium. At least one of X1, X2, or X3 is selected from Y1- or Y1-O—.
CONSTRUCTIVE ARRANGEMENTS IN 6-STRAND SYNTHETIC TWISTED LARIAT ROPE
It refers to the invention of a 6-strand synthetic twisted lariat rope, a product used in Team Roping competitions. It is also used in cattle handling, when it is necessary to immobilize an animal, preserving its sanity and physical integrity, avoiding injuries, friction burns due to impact and/or traction. It is a dynamic, elastic, anti-static rope where the harmful effect of the impact of a sudden stop is practically nil, which follows all the requirements of the Federal Law 10.591/02. First and foremost, the animal welfare is taken into account in Team Roping competitions. The evolution of Team Roping competitions is under constant improvement in Brazil and in the world, to which the present invention brings several benefits.
Method of Terminating a Stranded Synthetic Filament Cable
An apparatus and method for terminating a multi-stranded, non-parallel cable. An anchor is provided on the end of each strand. A collector is provided to link the anchors and connected strands into a single unit. An alignment fixture is provided to transition the strands from the non-parallel lay within the cable to a parallel path adjacent to the anchors.
Synthetic fiber rope
A synthetic fiber rope comprising:—a core, said core being a laid or braided synthetic fiber strand,—a polymer layer, said polymer layer covering said core,—a first layer, said first layer having at least six first synthetic fiber strands laid in a first direction surround said polymer layer, and—a second layer, said second layer having at least twelve second synthetic fiber strands laid in a second direction surround said first layer.
SMALL DIAMETER FIBER BRAID WITH CENTRAL CORE MEMBER
A cord comprises a braided sheath of strands having an outer surface, an inner surface, and a central hollow portion defined by the inner surface and having a volume and a core within the central hollow portion of the tubular braided sheath, such that when the cord is in a relaxed state the tubular braided sheath has a cylindrical shape and a relaxed volume of the central hollow portion wherein the core does not fill the relaxed volume of the central hollow portion of the tubular braided sheath; when the cord is in a longitudinal tensioned state, the tubular braided sheath elongates under the longitudinal tension such that a tensioned volume of at least a part of the central hollow portion of the tubular braided sheath is less than the relaxed volume; and the inner surface of the tubular braided sheath of tensioned volume contacts and cinches a surface of the core.
Underwater mooring rope
The present invention relates to a mooring rope for use in subsea mooring, or a substantially synthetic rope thereof, said synthetic rope including a rope core and a layered shell arranged around the rope core, said the shell having a braided outer shell layer. The shell includes sub-surface buoyancy elements, suitable for use in a subsea environment, extending in radial direction between the rope core and the outer shell.
APPARATUS FOR UNIFYING STRUCTURAL CONTINUOUS LOAD PATHS AND REINFORCING A ROOFING STRUCTURAL SYSTEM UTILIZING SUPER HIGH TENSILE STRENGTH TAPE AND PLASTIC ATTACHMENT MECHANISMS.
A new Super High Tensile Strength Tape (SHTST) which delivers super high performance in strength and low elongation which can be used in a roof reinforcing and attaching system to aid in securing the roofing members and supporting walls to the building's foundation, so as to supplement and unify the roofing assembly and wall sections in resistance to lift-off, failure and destruction in high-wind, seismic and other destructive events. Said SHTST can also be used in applications for automotive and vehicular, for packaging, for industrial uses, for military applications and for any other application where significant reinforcing and unifying resistance to destructive forces is desired.
ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE MULTIFILAMENT YARN
Multifilament yarn containing n filaments are provided, wherein the filaments are obtained by spinning an ultra-high molecular weight polyethylene (UHMWPE), said yarn having a tenacity (Ten) as expressed in cN/dtex of Ten(cN/dtex)=f×n.sup.−0.05×dpf .sup.−0.15, wherein Ten is at least 39 cN/dtex, n is at least 25, f is a factor of at least 58 and dpf is the dtex per filament.
Device for adjusting the discard state detection of high-strength fiber ropes and lifting gear comprising such a device
The present invention generally relates to the detection of the discard state of high-strength fiber ropes. The invention relates to a device for detecting the discard state of high-strength fiber ropes for various operating conditions, wherein a rope core of the fiber rope is sheathed with a rope sheath which is intended to wear more quickly than the rope core, comprising an optical detection device for detecting the rope surface and/or a load spectrum counter for detecting the load cycles to which the fiber rope is subjected, and on the other hand to a lifting gear such as a crane comprising such a device. According to the invention, there is provided a detection device for detecting the light absorption coefficient and/or the degree of reflection of the rope sheath and an adaptation device for adapting the algorithm, by means of which the discard state is determined, in dependence on the detected light absorption coefficient and/or the detected degree of reflection.
PROCESS AND DEVICE FOR SPLITTING A TAPE
A process and a splitter for splitting a tape of a uniaxially oriented material. The tape is passed in a process direction over a static splitting profile having a row of teeth, e.g., with a cutting edge extending in the process direction. The tape is split to form a material comprising a plurality of parallel strips interconnected by fibrils. The split material can for example be used for the production of high tensile ropes or laminates.
