Abstract:
Un procédé de fabrication d'un assemblage (A) d'éléments filaires (14) enroulés ensemble en hélice comprend : - une étape de retordage d'au moins des premier et deuxième éléments filaires (14), les premier et deuxième éléments filaires (14) étant retordus séparément l'un de l'autre, - une étape de préformation en hélice d'au moins les premier et deuxième éléments filaires retordus (14), les premier et deuxième éléments filaires retordus (14) étant préformés séparément l'un de l'autre, - une étape d'assemblage d'au moins les premier et deuxième éléments filaires (14) retordus et préformés pour former l'assemblage (A) d'éléments filaires (14).
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:
A high traction synthetic rope comprising a braided sheath (8) adhered to a synthetic strength member (7) by means of a first synthetic portion (9) and portions of material (23) adhered to the outside surface of the braided sheath by means of a second synthetic portion (21), where the portions of material (23) are formed of a substance that differs from a substance mainly forming the second synthetic portion (21) and exhibits greater friction when wet or with greasy conditions and measured on an iron surface than does the substance mainly forming the second synthetic portion. Also methods of manufacturing such a high traction synthetic rope are disclosed. The rope shows reliable traction on driven rotating elements during wet / greasy conditions.
Abstract:
A process for producing a high strength rope comprising the step of i) providing a uniaxially oriented tape (10) comprising ultra-high molecular weight polyethylene, the tape (10) having a tensile strength of at least 0.9 GPa, and ii) simultaneously twisting and fibrillating the tape (10) into a twisted strand of fibrillated tape with a coherent network of filaments and fibrils. A rope obtainable by the process and products comprising the rope are also disclosed.
Abstract:
Method for producing a cable, particularly a so called armored cable, comprising steps of: A - arranging a rope (3) B - Helically winding the outer surface of said rope (3) with at least an armor winding wire (1) so called armor wire (1) C - hammering said at least one armor wire (1) till squeezing it against said rope (3) causing said armor wire to be substantially flattened, generating a so called armor "strap" (1') covering substantially completely the rope (3) . The invention comprises also a cable, particularly an armored cable produced according to said method.
Abstract:
A steel wire (10) is coated with a metal layer (14) such that the metal layer (14) has a surface with roughnesses (16). A surface roughness Ra of above 0.25 µm is reached. Preferably, the roughnesses are randomly dispersed at the surface. The result is an improved visual aspect and an increased resistance against corrosion.
Abstract:
Gegenstand der Erfindung ist eine Angelschnur umfassend einen Kern aus mindestens einem Multifilamentgarn auf Basis synthetischer organischer Faserstoffe und einem aus Folienbändchen aus Polytetrafluorethylen (PTFE), welche in S-Richtung und Z-Richtung oder umgekehrt fest auf den Kern gewickelt sind, gebildeten Mantel.
