摘要:
The apparatus for making a cable by roebling individual rectangular cross-sectioned strands includes two pressing elements, each of the pressing elements extending in a direction (y-axis) perpendicular to the conveying direction (z-direction), engaging different stacks from the top side and bottom side of the cable respectively and being displaceable in opposite directions in a timed reciprocating manner to move stacks toward each other; two nonrotatable pushing members, each of which being mounted on opposite lateral sides of the cable, being structured and positioned to be moveable in another direction (x-axis) perpendicular to and across the conveying direction (z-axis) to displace respective individual strands to adjacent stacks and to simultaneously bend them; a nonrotatable counterabutment member spaced along the conveying direction from each of said pushing members and being mounted to be moveable oppositely to the pushing member associated therewith; a device for adjusting, prior to roebling, a spacing between each of the pushing members and nonrotatable counterabutment members associated therewith; and a hydraulic or pneumatic drive for moveably operating each of the pushing members and the pressing elements and an electronic control device synchronization of the drives.
摘要:
A method of manufacturing stranded cables having non-circular cross-section comprising drawing the strands through spaced-apart locations constrained to move around a predetermined non-circular path defining a shape corresponding generally to the desired cross-section of the cable, and subsequently passing the strands through first a stranding plate and then a die whilst maintaining a drawing force on the strands. Each of the locations comprises in effect, an off-centre point location on a disc caused to be driven around and in contact with the inside of a circle so that the point locations move with a substantially constant linear velocity. Alternatively each of the locations comprises, in effect, a point location on an endless chain caused to move to describe a shape corresponding generally to the desired cross-section of the cable.
