Patent number: 11845651Abstract: A spool (100) of a linear string (110, 210, 310, 410) of pocketed springs is disclosed. The linear string of pocketed springs comprises springs (212, 312, 412) each provided in a textile pocket (214, 314, 414). The springs (212, 312, 412) comprise helically coiled steel wire springs. The textile pockets (214, 314, 414) are assembled to each other in linear direction. The linear string (110, 210, 310, 410) has a width of one textile pocket (214, 314, 414).

Publication number: 20100068495Abstract: A steel cord (200) is described that is simple and cost effective to produce while solving some particular problems for the reinforcement of elastomer belts such as timing belts or the like. The cord (200) is a single lay cord that comprises a core filament (202), around which a first layer and a second layer of filaments (204, 210, 212) is twisted, all filaments being twisted with the same lay length and direction. By appropriate choice of the lay length, the core filament diameter and the filament diameters of the first layer—the latter being larger or equal to the former—an aggregate gap can form in which intermittently a filament (210?) of the second layer gets entrained. This aggregate gap must be between 40 and 70% of the core filament diameter in order to obtain the desired effect of having a core filament (202) that is deformed with the same lay length and direction as the other filaments (204,210,212). A deformed core filament (202) suppresses the effect of core filament migration.Type: ApplicationFiled: November 30, 2007Publication date: March 18, 2010Inventors: Hendrik Rommel, Bert Vanderbeken

Publication number: 20100009184Abstract: A cable (211) is provided comprising a steel cord (212) and a polymer material (215). The steel filaments (213) of the steel cord (212) are coated with an adhesive before the penetration of the polymer material (215). The cable (211) has a structural elongation less than 0.025% and an E module 4% greater than the E module of the steel cord (212). These two improvements further decrease the total elongation of the cable at certain load.Type: ApplicationFiled: January 4, 2008Publication date: January 14, 2010Inventors: Paul Bruyneel, Stijn Vancompernolle, Bert Vanderbeken

Patent number: 7426821Abstract: A metal strand comprising at least two filaments. At least one filament is interrupted, providing a filament end, which is fixed to the uninterrupted filaments of the strand using a fixing substance, preferably a soldering substance.

Publication number: 20070089394Abstract: A fine steel cord for the reinforcement of synchronous belts is presented. The fine cord has a distinct load elongation curve characterized by a very low structural elongation (below 0.09% preferably below 0.06%), and a high equivaslent modulus between 0.2 and 20% of the breaking, load. The favorable results are maintained when the cords are coated with an elastomer coating. Such a fine steel cord reduces the geometrical spread on the tooth pitch of the synchronous belts during use. A method to produce such a fine steel cord is also presented.Type: ApplicationFiled: October 15, 2004Publication date: April 26, 2007Inventors: Stijn Vancompernolle, Paul Bruyneel, Bert Vanderbeken

Patent number: 7191585Abstract: An elevator rope comprising an elastomer coated, multistrand steel wire cable is claimed. In such a cable strands have a lay-length of at least 6.5 times the diameter of the bare cable diameter D. The cable is further coated with an elastomeric jacket, which adheres to the strands with a pull-out force not less than 15×D+15 newton per mm. The advantages of such an elevator rope are amongst others its limited elongation, its reduced diameter and its improved fatigue life.Type: GrantFiled: January 29, 2004Date of Patent: March 20, 2007Assignee: NV Bekaert SAInventors: Bert Vanderbeken, Daniël Mauer, Rita Hostens, Legal Representative, Javier Del Rio Rodriguez, René Debue, Deceased late of
