Abstract
Abstract A rope forming machine in which consecutively installed between a reel holding a core of fibrous material and a rotor circumferencially mounting a plurality of wire reels for holding the outer strands of the rope is a spring forming mechanism for forming wire into a cylindrical spring which is used to surround the core brought off the core-holding reel and a device for determining the extent of tensioning of the cylindrical spring with the core enclosed therein after emerging from the spring forming mechanism. The rotational speed of the rotor and a drawing-off drum for drawing off the finished rope formed by twisting the strand around the formed cylindrical spring are controlled, to correlate the rate or rope twisting and that of cylindrical spring forming.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
253 words
A basket type rope-twisting machine for forming a continuous length of rope, comprising: a reel for holding a Fibrous core; rotatable-forming means for forming a reel of wire into a continuous cylindrical spring which is used to compressively surround the core delivered thereto from said reel; first driving means for rotatably driving said rotatable forming means during formation of said cylindrical spring; a device operatively associated with said rotatable forming means for determining the extent of tensioning the formed cylindrical spring with the core enclosed therein; a rotor having a plurality of circumferentially positioned wire-holding reels for providing an equal plurality of wire strands; a shaft for mounting said rotor and being hollow to allow passage therethrough of said cylindrical spring together with the core enclosed therein; second driving means for rotating said shaft whereby said wire strands are wrapped around the cylindrical spring with the inner core, emerging from said hollow shaft after passage therethrough, to form the continuous length of rope; a drawing-off drum for imparting progressive motion to the thus formed rope and being kinematically coupled with said second driving means; a receiving drum for winding the formed rope, and being kinematically coupled with said second driving means, said device for determining the extent of tensioning said cylindrical spring with the core being kinematically coupled with said second driving means to control the rotational speed of said rotor and said drawing-off drum thereby to correlate the rate of rope wrapping by said strands with that of forming said cylindrical spring.
Claim 2
Dependent Claim

A basket type rope-twisting machine for forming a continuous length of rope, comprising: a reel for holding a Fibrous core; rotatable-forming means for forming a reel of wire into a continuous cylindrical spring which is used to compressively surround the core delivered thereto from said reel; first driving means for rotatably driving said rotatable forming means during formation of said cylindrical spring; a device operatively associated with said rotatable forming means for determining the extent of tensioning the formed cylindrical spring with the core enclosed therein; a rotor having a plurality of circumferentially positioned wire-holding reels for providing an equal plurality of wire strands; a shaft for mounting said rotor and being hollow to allow passage therethrough of said cylindrical spring together with the core enclosed therein; second driving means for rotating said shaft whereby said wire strands are wrapped around the cylindrical spring with the inner core, emerging from said hollow shaft after passage therethrough, to form the continuous length of rope; a drawing-off drum for imparting progressive motion to the thus formed rope and being kinematically coupled with said second driving means; a receiving drum for winding the formed rope, and being kinematically coupled with said second driving means, said device for determining the extent of tensioning said cylindrical spring with the core being kinematically coupled with said second driving means to control the rotational speed of said rotor and said drawing-off drum thereby to correlate the rate of rope wrapping by said strands with that of forming said cylindrical spring.
Claim 3
Dependent Claim
84 words
A rope-twisting machine as set forth in claim 1, wherein said rotatable forming means comprises a wire holding reel freely mounted on a hollow shaft having a drive-connected drum, said drive connected drum directing the wire to a first set of rollers kinematically linked with said first driving means drive for positive delivery of the wire therefrom to a second set of rollers for commencing spiral formation of the wire so that the sprial formed thereby is located adjacent the hollow of said shaft.
