    • A power transmission belt with a good balance of high temperature resistance, good belt durability and low temperature flexibility, and a service range of about -40° C. to about 140° C. The main belt body portion of the power transmission belt is manufactured from an elastomeric material comprising 100 parts by weight of an at least partially hydrogenated nitrile group-containing copolymer rubber, and from about 0.5 to about 50 parts per hundred weight of said rubber of a fiber reinforcement having a length to diameter ratio of greater than 10:1. The nitrile group-containing copolymer rubber preferably comprises (1) from about 5 to about 40 percent of unsaturated nitrile monomer units, (2) from about 1 to about 80 percent of units of at least one second monomer selected from the group consisting of fluorine-free unsaturated carboxylic acid ester monomer units and fluorine-containing vinyl monomer units, or any monomer possessing the characteristic of lowering the glass transition temperature of the rubber; (3) up to about 20 percent of conjugated diene monomer units and (4) the balance being hydrogenated conjugated diene monomer units, preferably wherein the sum of the contents of the monomer units (1) and (2) is preferably from about 30 to 90 percent by weight and the sum of the contents of the monomer units (3) and (4) is from about 10 to about 70 percent by weight. The use of the fiber reinforcement in the nitrile group-containing, highly saturated copolymer rubber provides substantially improved low temperature crack resistance while improving the high temperature resistance of the belt.

    • A method and apparatus for accurately applying a cord to a rotatable mandrel utilizes control of cord length, rather than cord tension, as the control parameter. The apparatus includes a mandrel with an inflatable diaphragm mounted on an outer surface of the mandrel. The diaphragm is selectively inflatable via a control valve and source of pressurized fluid for dynamically adjusting a circumference of the mandrel in response to a control input. The control input reads a tension in the cord being wound. The cord is positively fed to the mandrel according to a defined algorithm based on the mandrel's shape, circumference and rotational speed, rather than by demand feed of the cord. The apparatus includes a positive feed control capstan which is electronically geared. The apparatus further includes a cord-laying wheel which isolates radially directed forces from circumferentially-directed forces. A second embodiment of the invention includes the belt being rotated on first and second pulleys while the cord is applied. A center distance between the first and second pulleys is selectively adjustable to control cord tension in the cord.
    • 用于将绳索准确地应用于可旋转心轴的方法和装置利用绳索长度而不是帘线张力作为控制参数。 该设备包括具有安装在心轴的外表面上的可膨胀隔膜的心轴。 隔膜通过控制阀和加压流体源选择性充气,以响应控制输入动态调节心轴的周长。 控制输入​​读取正在缠绕的绳索中的张力。 根据基于心轴形状,圆周和旋转速度的限定算法,而不是根据需要进给的帘线,将帘线肯定地供给到心轴。 该设备包括电子齿轮传动的正向进给控制绞盘。 该装置还包括一个将放射状定向力与周向力隔离的帘线放置轮。 本发明的第二实施例包括在帘线被施加时带在第一和第二滑轮上旋转。 第一滑轮和第二滑轮之间的中心距可选择性地调节以控制绳索中的绳索张力。
