Abstract
Abstract This invention concerns cable making machines and relates to a machine incorporating both twisting and cabling mechanisms. The apparatus is designed to enable the lapping section of the machine to be isolated from the twisting section in order that the machine can be used selectively for both twisting and lapping or twisting only. Common drive means is provided for the machine such drive means including, for example, a clutch for isolating the drive to the lapping section of the machine when required.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
A twisting and lapping machine for filamentary material, there being a first cradle means for carrying at least a take-up device for the filamentary material, and around which is rotatable a twister bow, and a second cradle means spaced from the first cradle means and substantially in axial alignment therewith for carrying at least one means for lapping and around which is rotatable a filamentary material, common drive means for driving the twister bow and means for lapping, means for disconnecting the drive to the means for lapping when required, guide means for guiding the filamentary material, and there being filamentary material diverter means between the first and second cradle means for guiding the filamentary material either directly to the take-up device or to the means for lapping and then the take-up device.
Claim 2
Dependent Claim
133 words
A twisting and lapping machine for filamentary material, there being a first cradle means for carrying at least a take-up device for the filamentary material, and around which is rotatable a twister bow, and a second cradle means spaced from the first cradle means and substantially in axial alignment therewith for carrying at least one means for lapping and around which is rotatable a filamentary material, common drive means for driving the twister bow and means for lapping, means for disconnecting the drive to the means for lapping when required, guide means for guiding the filamentary material, and there being filamentary material diverter means between the first and second cradle means for guiding the filamentary material either directly to the take-up device or to the means for lapping and then the take-up device.
Claim 3
Dependent Claim
127 words
A twisting and lapping machine for filamentary material, there being a first cradle means carrying at least a take-up devicd for the filamentary material, and around which is rotatable a twister bow, and a second cradle means spaced from the first cradle means and substantially in axial alignment therewith, said second cradle means carrying at least one lapping means and around which is rotatable a filamentary material guide means, there being filamentary material diverter means between the first and second cradle means for guiding the filamentary material either directly to the take-up device or to the lapping means and then the take-up device, and drive means for driving said lapping means, said drive means including means for disconnecting the drive means from said lapping means when required.
Claim 4
Dependent Claim
127 words
A twisting and lapping machine for filamentary material, there being a first cradle means carrying at least a take-up devicd for the filamentary material, and around which is rotatable a twister bow, and a second cradle means spaced from the first cradle means and substantially in axial alignment therewith, said second cradle means carrying at least one lapping means and around which is rotatable a filamentary material guide means, there being filamentary material diverter means between the first and second cradle means for guiding the filamentary material either directly to the take-up device or to the lapping means and then the take-up device, and drive means for driving said lapping means, said drive means including means for disconnecting the drive means from said lapping means when required.
Claim 5
Dependent Claim
26 words
A machine as claimed in claim 2 in which the take-up device comprises a capstan and a take-up reel adapted to be driven by the capstan.
Claim 6
Dependent Claim
37 words
A machine as claimed in claim 2 in which the lapping means includes a carrier disc for a lapping material supply reel, said disc being adapted to be driven via drive means on the second cradle means.
Claim 7
Dependent Claim
45 words
A machine as claimed in claim 2 in which the rotatable filamentary guide means of the second cradle means includes rotatable shafts through which twisted filamentary material to be lapped can pass and support means mounted on the rotatable shafts for carrying cable guide pulleys.
Claim 8
Dependent Claim
59 words
A machine as claimed in claim 2 in which the filamentary material diverter means is in the form of a guide element arranged adjacent a cradle shaft of said first cradle means and so disposed as to lead twisted filamentary material directly from the twister bow to a bore in the same shaft and thus to the take-up device.
Claim 9
Dependent Claim
121 words
A twisting and lapping machine for filamentary material, there being a first cradle means carrying at least a take-up device for the filamentary material, and around which is rotatable a twister bow, and a second cradle means spaced from the first cradle means, said second cradle means carrying at least a lapping means and around which is rotatable a filamentary material guide means, there being filamentary material diverter means between the first and second cradle means for guiding the filamentary material either directly to the take-up device or to the lapping means and then the take-up device, and drive means for driving said lapping means, said drive means including means for disconnecting the drive means from said lapping means when required.
Claim 10
Dependent Claim
121 words
A twisting and lapping machine for filamentary material, there being a first cradle means carrying at least a take-up device for the filamentary material, and around which is rotatable a twister bow, and a second cradle means spaced from the first cradle means, said second cradle means carrying at least a lapping means and around which is rotatable a filamentary material guide means, there being filamentary material diverter means between the first and second cradle means for guiding the filamentary material either directly to the take-up device or to the lapping means and then the take-up device, and drive means for driving said lapping means, said drive means including means for disconnecting the drive means from said lapping means when required.
