Abstract:
An exemplary method of making a woven fabric includes weaving a plurality of load supporting tension members and a plurality of cross fibers together into a woven fabric. A spacing between adjacent ones of the tension members has a first dimension. At least some of the cross fibers are shrunk to thereby decrease the spacing between the adjacent ones of the tension members to a second, smaller dimension. In another example, two woven fabrics are positioned next to each other. The two fabrics include a spacing between adjacent tension members having a first dimension. At least one tension member of one woven fabric is aligned with and between two of the tension members of the other fabric to thereby decrease the spacing to a second, smaller dimension.
Abstract:
The invention relates to a rope made of textile fiber material for applications in which oblique pulling can occur, characterized in that the rope is a core-and-sheath rope, the core (1) and sheath of which are substantially made of textile fiber material, the core (1) of which is stranded, and which has a friction-locking winding of a tension element (2, 2', 2'') between the core (1) and the sheath.
Abstract:
A method for manufacturing a hoisting rope (R,R',R",R"'), comprising the steps of providing a plurality of elongated composite members (1,1',1",1"'), which composite members (1,1',1",1"') are made of composite material comprising reinforcing fibers (f) in polymer matrix (m); arranging the composite members (1,1',1",1"') to form an elongated row (r,r',r",r"') of parallel composite members 1,1',1",1"', which row (r,r',r",r"') has a longitudinal direction (L), a thickness direction (T) and a width direction (W), and in which row (r,r',r",r"') the composite members (1,1',1",1"') are positioned side by side such that they are parallel to each other, and spaced apart from each other in width direction (W) of the row (r,r',r",r"'); directing plasma treatment on the outer surface of the composite members (1,1',1",1"'); embedding the composite members (1,1',1",1"') in fluid polymer material (2); and solidifying the polymer material wherein the composite members (1,1',1",1"') are embedded. A hoisting rope (R,R',R",R"') obtained with the method and an elevator comprising the hoisting rope (R,R',R",R"') are disclosed, too. The plasma treatment allows for an increased transmission ability of a hoisting rope compared to no plasma treatment.
Abstract:
An exemplary method of making a woven fabric (20A, 20B) includes weaving a plurality of load supporting tension members (22A, 22B) and a plurality of cross fibers (24) together into a woven fabric (20A, 20B). Two woven fabrics (20A, 20B) are positioned next to each other. The two woven fabrics (20A, 20B) include a spacing between adjacent tension members (22A, 22B) having a first dimension. At least one tension member (22A) of one woven fabric (20A) is aligned with and between two of the tension members (22B) of the other woven fabric (20B) to thereby decrease the spacing to a second, smaller dimension.
