SELF-EXTINGUISHING LOAD BEARING MEMBER FOR ELEVATOR SYSTEM
A belt for an elevator system includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt, and a jacket at least partially enclosing the plurality of tension members. The jacket defines a traction side of the belt configured to interface with a traction sheave of an elevator system, and is formed from a self-extinguishing fluoroelastomer material. An elevator system includes a hoistway, an elevator car located in the hoistway and movable therein, and a belt operably connected to the elevator car to suspend and/or drive the elevator car along the hoistway. The belt includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt, and a jacket at least partially enclosing the plurality of tension members. The jacket is formed from a self-extinguishing fluoroelastomer material.
SELF-EXTINGUISHING FABRIC BELT FOR ELEVATOR SYSTEM
A belt for suspending and/or driving an elevator car including a plurality of tension elements extending longitudinally along a length of the belt, and a plurality of yarns interlaced with the plurality of tension elements forming a composite belt structure. The plurality of yarns are formed from a self-extinguishing fluoroelastomer material. An elevator system includes a hoistway, an elevator car positioned in the hoistway and movable therein, a belt operably connected to the elevator car to suspend and/or drive the elevator car along the hoistway. The belt includes a plurality of tension elements extending longitudinally along a length of the belt and a plurality of yarns interlaced with the plurality of tension elements forming a composite belt structure. The plurality of yarns are formed from a self-extinguishing fluoroelastomer material.

Draw tape for cables or similar flexible elements
Draw tape for cables including an elongated flexible element made of a helical multifilament rope composed of three filaments or strands helically wound about a common longitudinal axis. According to an additional feature, the rope is hammered. Still according to an improvement, the rope is externally covered by a jacket.

Fishing line of core-sheath structure comprising short fiber
A yarn which contains a composite yarn composed of a core part containing a short fiber and a sheath part containing a synthetic fiber filament yarn, the core part and the sheath part being integrated via fluff of the short fiber getting between or entangled with the long fibers, the specific gravity of the yarn being adjustable in the range of 1.0 or more, a fishing line containing the yarn, and a method for producing the fishing line. The present invention provides an ideal fishing line which has a strong core-sheath structure, does not allow separation or detachment of the core part and the sheath part, is easy to handle, and also is excellent in strength, weatherability, and water resistance.

LOW SLIP SPLICE
A rope system (10, 20) comprising a splice structure (12, 22) with an intact portion (23) comprising at least 8 intact strands (32, 34), and a disassembled portion (26) comprising at least 4 loose strands (30), wherein the intact portion (23) is a braid of at least 4 S oriented (32) and at least 4 Z oriented intact strands (34), wherein at least one loose strand (30) of the disassembled portion (26) passes under and over intact strands (32, 34) of the intact portion (23), and at least one loose strand (30) passes under at least one X-tuck (38) of intact strands (32, 34). By this means the splice length can be minimized resp. slippage of the splice at high loads can be avoided.

ELEVATOR TENSION MEMBER
A belt for suspending and/or driving an elevator car includes a plurality of cords. Each cord includes a plurality of wires and at least one yarn thread disposed at an outer periphery of the plurality of wires. An elastomeric jacket substantially retains the plurality of cords. The at least one yarn thread is configured to promote adhesion of the elastomeric jacket to the plurality of cords and reduce fretting of the plurality of wires. A method of forming a belt includes arranging a plurality of wires into a cord, arranging one or more yarn threads at an outer periphery of the plurality of wires, arranging a plurality of cords into a selected arrangement and applying an elastomeric jacket to the cords to retain the cords. The one or more yarn threads are configured to promote adhesion of the elastomeric jacket to the cords and reduce fretting of the wires.
