Cable marking method and apparatus

Apparatus for marking an identification at pre-selected intervals along a cable length by laser marking means and including drive means adapted during use to sequentially move an alternate one of two longitudinally spaced-apart portions of the cable length which are located in parallel juxtaposed relationship along a marking platen while maintaining the other portion stationary, and positioning means adapted to establish an operative relationship between the laser marking means and the stationary one of the cable portions whereby the stationary portion is marked while the other cable portion is moving across the platen.

Apparatus for marking an identification at pre-selected intervals along a cable length comprising a carriage block assembly including a marking platen and laser operated marking means positioned above the platen, wherein longitudinally spaced-apart input and output portions of a cable length are routed across the platen in substantially parallel juxtaposed relationship, said apparatus including drive means to sequentially move an alternate one of the input and output portions across the platen while maintaining the other portion stationary and positioning means to alternately position the laser marking means in operative relationship with the stationary one of the cable portions whereby the stationary portion is marked while the other cable portion is moving across the platen.

Apparatus for marking an identification at selected intervals along a cable length comprising a carriage block assembly including a marking platen and a laser operated marking means positioned above the platen, wherein apertures are provided upstream and downstream of the platen and an input portion of the cable is located along the platen through the downstream aperture and up through the upstream aperture to form a slack loop below the platen, an output portion of the cable being located across the platen in parallel juxtaposed relationship with the input portion, and including drive means arranged to sequentially move an alternate one of said input and output cable portions while maintaining the other portion stationary, and control means arranged to operate said drive means and said laser means and to position said laser means so as to mark the stationary one of said input and output portions whereby the stationary portion is marked while the other cable portion is moving across the platen.

Apparatus for marking an identification at selected intervals along a length of cable and comprising a carriage block assembly including a marking platen, apertures at upstream and downstream ends of the platen, an input portion of the cable being routed across the platen, down through the downstream aperture and up through the upstream aperture to form a loop portion below the platen, an output portion of the cable being routed across the platen in parallel juxtaposed relationship to the input portion, first drive means adapted to drive the input portion of the cable across the surface of the platen, second drive means arranged to draw the output portion of the cable from the surface of the platen, a laser operated marking means positioned above the platen so as to be capable of longitudinal movement relative to the platen and of lateral movement at least sufficient to encompass the input and output portions of the cable, and control means adapted to control sequential operation of the first and second drive means such that an alternate one of the input and output cable portions is sequentially moved while the other portion is maintained stationary and to alternately position the laser marking means above the stationary one of said input and output portions of the cable.
