Abstract
The apparatus for producing raised markings on a cable's plastic jacket disclosed provides for at least one drum shaped marking member, which may be driven by the cable itself or, if there are a pair of such drums, at least one is driven by means of a stepper motor which is controlled synchronously with the cable take-off speed. The drums are vertically adjustable and mounted on swivel arms carried on a carriage. Pneumatic means are employed to force the drum or drums against the moving cable with a predetermined pressure. Depressions corresponding to the desired markings are formed in the circumferential surface of the drum. As the drum or drums rotate a powder filled container or filling head is pressed against them so that powder is picked up in the depressions and carried by the drums into contact with the cable. When the powder filled depression area of the drum contacts the cable, which is still hot, the powder will fuse with the material of the cable's jacket and form a raised marking. The depressions may be symbols, letters, numerical length marks and the like.
