    Abstract: A rope including polyethylene elongate elements oriented in the length direction of the rope, where for at least part of the elongate elements the distance of the element to a central longitudinal rope axis varies over the length of the rope. The polyethylene elongate elements including tapes of ultra-high molecular weight polyethylene, the tapes having a width to thickness ratio of at least 10 and a polymer solvent content below 0.05 wt. %. The distance of at least part of the elements to the central longitudinal rope axis varies over the length of the rope between a longitudinal line which is at most 30% from the outside of the rope and a longitudinal line which is at most 30% from the central longitudinal axis of the rope. Such a rope shows a high strength-strength ratio (the ratio between the strength under use conditions and the fresh strength of the rope).

    Abstract: A cable protecting tube having high transparency and allowing the filling condition of mortar therein to be visually observed from the outside as well as exhibiting high pressure resistance is provided. A cable protecting tube for accommodating a cable and for filling with mortar includes a protecting tube (1) having smooth inner and outer surfaces formed from an ionomer resin excellent in transparency, and a spiral or mesh-shaped reinforcing member (2) for reinforcing the protecting tube. The reinforcing member (2) may be buried in the protecting tube (1). The protecting tube (1) is not limited to the smooth-walled tube but may be a spirally corrugated tube.

    Abstract: 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—.
