    Abstract: An improved rope is formed from high tenacity fibers, preferably a blend of high tenacity polyethylene fibers with aramid fibers and/or liquid crystal copolyester fibers. The fibers and/or the rope are coated with a composition comprising an amino functional silicone resin and a neutralized low molecular weight polyethylene. The ropes are useful in marine applications, such as in deep sea lifting, and have improved cyclic bend over sheave fatigue resistance.

    Abstract: An apparatus and method for extruding a thin uniform coating of fluent plastic material about a continuously advancing strand wherein the fluent plastic material is directed radially toward the strand through a constricted annular feed passage. The strand with the fluent plastic material adhering thereto is then advanced through a passageway conically converging to an exit end and effective to develop hydrodynamic pressure forces which center the strand within the passageway.

    Abstract translation: 一种用于挤出流动塑料材料的薄均匀涂层的装置和方法,其围绕连续前进的股线,其中流动的塑料材料通过收缩的环形进给通道径向地朝向股线。 然后将粘附有流动性塑料材料的线材推进通过锥形会聚到出口端的通道,并且有效地产生使绞线在通道内居中的流体动力学压力。
