Belt with corrugated material
An elevator system includes a hoistway, an elevator car movable along the hoistway, and one or more belts operably connected to the elevator car to propel the elevator car along the hoistway. A belt of the one or more belts includes one or more tension elements extending along a belt length, and a jacket at least partially encapsulating the one or more tension elements. The jacket includes a jacket base formed from a first material and one or more insert layers embedded in the jacket base material. The one or more insert layers have a corrugated shape along the belt length, and are formed from a second material different from the first material.
CLEAR FLOATING FLY LINE WITH REDUCED REEL MEMORY AND METHODS OF MANUFACTURE
Improved fishing lines, and specifically fly lines, and methods of manufacture are shown. The line includes a copolyester ether material monofilament core line portion and a polyethylene copolymer coating portion providing highly improved toughness, line clarity and reel memory characteristics.
ELEVATOR LOAD BEARING MEMBER HAVING A JACKET INCLUDING A FLUOROPOLYMER
An illustrative example embodiment of an elevator load bearing member includes a plurality of load bearing cords and a jacket at least partially surrounding the cords. The jacket includes an inner portion received on the cords and a fluoropolymer outer portion that establishes a fire-resistant exterior of the jacket.
ELEVATOR LOAD BEARING MEMBER INCLUDING A UNIDIRECTIONAL WEAVE
An illustrative example embodiment of an elevator load bearing member includes a unidirectional weave of a plurality of load bearing fibers including at least a first material and a second material. A melting point of the first material is higher than a melting point of the second material. The plurality of load bearing fibers are bonded together by at least some of the second material that is at least partially melted. A coating covers the plurality of load bearing fibers.
ELEVATOR LOAD BEARING MEMBER HAVING A FABRIC STRUCTURE
An illustrative example assembly for making an elevator load bearing member includes a fabric having a plurality of fibers arranged with some of the fibers transverse to others of the fibers. A plurality of cords are configured to support a load associated with an elevator car. The cords are included in the fabric and have respective coatings. The coatings include a first coating material and a second coating material, or include different coating thicknesses such that some of the coatings have a different coating thickness than others of the coatings, or the coatings include the first coating material and the second coating material and some of the coatings have a different coating thickness than others of the coatings.
CABLE STRANDING APPARATUS EMPLOYING A HOLLOW-SHAFT GUIDE MEMBER DRIVER
A cable-stranding apparatus includes a stationary guide, a motor, a driven guide, and a controller electrically coupled to the motor. The stationary guide is configured to guide strand elements in a spaced-apart configuration and to pass a core member. The motor is operatively associated with a guide driver. The driven guide is disposed at least partially within the guide driver so as to rotate therewith. The driven guide is configured to receive the strand elements from the stationary guide, individually guide the strand elements received from the stationary guide, and to further pass the core member. The controller is electrically coupled to the motor and configured to control the rotational speed and direction of the motor.
Rope and method for producing a rope
A method for producing a rope, wherein fiber bundles are applied with a liquefied matrix material upstream of and/or at a twisting point to form fiber strands, and are embedded into the liquefied matrix material during stranding, by which fiber strands a fiber core of the rope is formed and wires or wire strands are wound about the fiber core. The matrix material of the fiber strands is hardened after the stranding, and the fiber strands are subsequently stranded directly with one another without further application to form the fiber core. Preferably the fiber strands are heated, during or after the stranding thereof to form the fiber core, so that the matrix material softens at least individual of the fiber strands, preferably all the fiber strands, softens and connects with the matrix material of another of the fiber strands, and is subsequently hardened, forming an integral bond with one another.
ELEVATOR TENSION MEMBER
A belt for suspending and/or driving an elevator car includes a tension member extending along a length of the belt, the tension member including a plurality of fibers bonded in a first polymer matrix, the plurality of fibers extending parallel to and discontinuous along a length of the belt and arranged with one or more lengthwise extending gaps between lengthwise adjacent fibers. A jacket substantially retains the tension member. A method of forming a tension member for an elevator system belt includes arranging a plurality of fibers into a fiber bundle. The plurality of fibers extend parallel to a length of the belt and have one or more lengthwise extending gaps between lengthwise extending fibers. The plurality of fibers is bonded to a first polymer matrix.
Method for Producing a Tension Member, Tension Member, and Use Thereof
The invention relates to a method for filling in a tension member in particular for conveyor belts, in particular a tension member which is configured as a steel cable. The method is intended to allow the full penetration of the tension member structure. Here, the method contains at least the following method steps: introducing the individual wires (2, 2, 2, 2, 2) of the strand (5) into the stranding head (1) of a stranding machine (10) and partially or fully applying at least one coating agent to at least 50% of the individual wires (2, 2, 2, 2, 2) of the strand (5) prior to the twisting of the individual wires (2, 2, 2, 2, 2) to form a strand (5) or simultaneously with the twisting of the individual wires (2, 2, 2, 2, 2) to form a strand (5) and twisting the individual wires (2, 2, 2, 2, 2) to form a strand (5), wherein at least 50% of the individual wires (2, 2, 2, 2, 2) have been provided with at least one coating agent, and making a cable from at least one strand (5).
