PROBLEM TO BE SOLVED: To provide a pneumatic tire excellent in steering stability and vibration ride comfort. SOLUTION: The pneumatic tire is provided with a carcass 2 and a crossing belt layer 3 using a steel cord as a reinforcement material. A bead core 1 is a bead core comprising a mono-strand formed by helically winding a circular cross section wire 4 covered by a rubber 5 and bundling it, and its cross section is the close-packed unit formed by the wire. When the number of the wires of the second row from a bead base surface side is made as N(2), formula N(2)=N(1)+1 is satisfied, and rigidity of the steel cord per unit width of the crossing belt layer 3 satisfies a formula (A-800)/B≥20, wherein A is cord traction rigidity (kg) defined by stress at 1% traction × the number of hitting (number/50 mm), and B is cord bending rigidity (g/mm) defined by inclination at 2-6 mm pushing-in deformation of stress-bending displacement curve obtained by cord 3-point bending test × the number of hitting (number/50 mm).

Abstract:
Изобретение может быть использовано при производстве преднапряженной и закладной канатной арматуры. Арматурный канат состоит из центральной проволоки (1) и расположенных вокруг нее по спирали повивочных проволок (2) внутреннего слоя и повивочных проволок (4) внешнего слоя, каждая из которых имеет участок поверхности, являющийся частью наружной поверхности каната. Расстояние между поверхностями повивочных проволок внешнего слоя (4) составляет не менее половины их радиального размера сечения, при этом на обращенных друг к другу участках поверхности смежных проволок выполнены непрерывные по длине спиральные грани (5), а участок поверхности каждой из повивочных проволок внешнего слоя (4), являющийся частью наружной поверхности каната, имеет по меньшей мере одну обжатую часть (6) непрерывную по всей длине указанных проволок. Представлен также способ изготовления такого каната, состоящий из этапов, на которых изготавливают проволоки круглого сечения, свивают проволоки с помощью канатовьющей машины с вращающимся ротором, осуществляют пластическое обжатие свитого каната путем деформации повивочных проволок в по меньшей мере одном роликовом калибре, вращающемся относительно оси каната, подвергают обжатый канат термомеханической обработке. Существенно увеличивается выносливость каната, при одновременном обеспечении высокого сцеплением с бетоном в продольном направлении и в направлении ввинчивания.
Abstract:
A method for manufacturing a flexible composite belt or cable. In the meth- od, one or more parallel reinforced plastic profiles (11) are manufactured by pultrusion, continuous lamination or other continuous method. After surface treatment, the reinforced plastic profiles (11) are guided at a short distance from one another to coating treatment, which is carried out by extrusion or lamination or pultrusion. In the coating treatment, the reinforced plastic pro- files are enveloped with a coating material (12) improving wear resistance which joins the reinforced plastic profiles (11) together and forms the coating of a finished belt or cable (10). Finally, the finished belt or cable (10) is wound on a reel.
Abstract:
The invention relates to an endless shaped article comprising at least one strip of material forming a plurality of convolutions of the strip of material, the strip having a longitudinal axis, wherein each convolution of said strip comprises a twist along the longitudinal axis of said strip, wherein said twist is an odd multiple of 180 degrees. The invention also relates to a method to manufacture said article, and its use as sling, loop, belt or chain link.

Abstract:
Elevator, which comprises at least an elevator car (C) and means for moving the elevator car, preferably along guide rails, and a counterweight (CW), and one or more ropes (R,R',R''), which rope connects the elevator car and the counterweight (CW) and is separate from the supporting function and passes around a diverting pulley (11) mounted on the bottom end of the elevator hoistway. The rope (R,R',R'') comprises a power transmission part (2) or a plurality of power transmission parts (2), for transmitting power in the longitudinal direction of the rope, which power transmission part (2) is essentially fully of non-metallic material.
Abstract:
A method for forming a sling or a splice of an eye formed of coverbraided rope comprising the step of situating a void spacer adjacent to a portion of core rope. A method for producing a spliced sling of a coverbraided rope, the method comprising steps of : a) providing a void spacer; b) situating the void spacer alongside at least a portion of an intended splice braid zone of a strength member core; and c) covering at least portions of the void spacer with at least a portion of a braided sheath.
