Rope-making machine

Claim 2

A rope-making machine comprising a plurality of reel-carrying cradles aligned along an axis (X--X) and oscillating about said axis, and a plurality of first strand guide structures supported rotatably about said axis, wherein said machine further includes respective couplings which are rotatable about said axis and fix said cradles together in pairs coaxially, whereby said cradles define a rigid beam with said couplings, and a fixed stand at each end of said beam which supports a respective end of said beam free of intermediate supports, said first strand guide structures being supported by said couplings, and second strand guide structures of tubular form spaced from and parallel to said axis, said second strand guide structures supported from respective ones of said couplings.

Claim 3

A rope-making machine comprising a plurality of reel-carrying cradles aligned along an axis, respective pins at the ends of said cradles by means of which the latter oscillate about said axis, and a plurality of tubular strand guide structures rotatably supported about said cradles coaxially with said axis, wherein said machine further includes a pair of fixed stands which rotatably support the respective outer pins of the end cradles of said aligned cradles free of intermediate supports, a respective rotatable hub interposed between at least one of said outer pins and its respective stand, and respective hubs mounted rotatably on respective pairs of intermediate pins between adjacent cradles in said alignment, each hub being mounted rotatably on each of said intermediate pins by two bearings located at a predetermined distance apart, whereby said cradles and said hubs define a rigid beam, said strand guide structures being supported by said hubs.

Claim 4

A rope-making machine comprising a plurality of reel-carrying cradles aligned along an axis, respective pins at the ends of said cradles by means of which the latter oscillate about said axis, and a plurality of tubular strand guide structures rotatably supported about said cradles coaxially with said axis, wherein said machine further includes a pair of fixed stands which rotatably support the respective outer pins of the end cradles of said aligned cradles free of intermediate supports, a respective rotatable hub interposed between at least one of said outer pins and its respective stand, and respective hubs mounted rotatably on respective pairs of intermediate pins between adjacent cradles in said alignment, each hub being mounted rotatably on each of said intermediate pins by two bearings located at a predetermined distance apart, whereby said cradles and said hubs define a rigid beam, said strand guide structures being supported by said hubs.

Claim 5

A rope-making machine comprising a plurality of reel-carrying cradles aligned along an axis, respective bushes at the ends of said cradles by means of which the latter oscillate about said axis, and a plurality of mutually-aligned tubular strand guide structures supported rotatably about said cradles coaxially with said axis, wherein said machine further includes a pair of fixed stands which rotatably support the respective outer bushes of the end cradles of said alignment of cradles free of intermediate supports, a respective rotatable pin interposed between at least one of said outer bushes and its respective stand, respective lengths of shaft located between the cradles of each pair of adjacent cradles of said alignment, each length of shaft having a central portion and opposite end portions mounted rotatably in the adjacent bushes of adjacent cradles of the said alignment, each portion of a length of shaft being mounted rotatably in a respective bush by two bearings located at a predetermined distance apart, whereby said cradles and said lengths of shaft define a rigid beam, said strand guide structures being supported by said lengths of shaft.

Claim 6

A rope-making machine comprising a plurality of reel-carrying cradles aligned along an axis, respective bushes at the ends of said cradles by means of which the latter oscillate about said axis, and a plurality of mutually-aligned tubular strand guide structures supported rotatably about said cradles coaxially with said axis, wherein said machine further includes a pair of fixed stands which rotatably support the respective outer bushes of the end cradles of said alignment of cradles free of intermediate supports, a respective rotatable pin interposed between at least one of said outer bushes and its respective stand, respective lengths of shaft located between the cradles of each pair of adjacent cradles of said alignment, each length of shaft having a central portion and opposite end portions mounted rotatably in the adjacent bushes of adjacent cradles of the said alignment, each portion of a length of shaft being mounted rotatably in a respective bush by two bearings located at a predetermined distance apart, whereby said cradles and said lengths of shaft define a rigid beam, said strand guide structures being supported by said lengths of shaft.

Claim 7

A rope-making machine in accordance with claim 2 wherein said pins are hollow and define guide passages for strands.

Claim 8

A rope-making machine in accordance with claim 1 wherein said first strand guide structures extend outwardly from said axis.

Claim 9

A rope-making machine in accordance with claim 1 wherein said strand guide structures define respective linear paths for strands that pass therethrough.
