A polishing apparatus for reducing the roughness and abrasive shedding of coated tapes comprises a cylinder having coaxial channels or grooves of various forms, which are advantageously thread-like. Axial grooves may be additionally provided.

Apparatus for reducing the roughness and abrasive shedding of coating tapes

A mechanical and finishing and/or signal processing apparatus for tapes, in particular magnetic tapes, includes at least two tape transporting devices, which apply an average tape tension of 2 N per inch (25.4 mm) of tape width and consequently remain below about 20% of the maximum tensile force of the tape material, to avoid permanent material deformations. The processing devices may be smoothing, abrading, polishing and cleaning devices and also signal recording/reproducing devices and/or signal or tape quality control devices.
