Abstract

An apparatus for transporting an elongated recording band comprising: a rotating winch having a practically cylindrical peripheral surface adapted to cooperate with a recording band, a cover of a first material placed and fixed on the peripheral surface of the winch, the first material it has a coefficient of friction determined to produce between the winch and one side of the recording band a friction force of relatively high value during contact with it, a non-rotating guide element stationary with respect to the direction of movement of the band and which includes a surface for engaging the other side of the recording band opposite the winch, the guide surface includes additional material that exhibits a coefficient of friction that is less than the coefficient of friction determined to produce between the guide surface and the other side of the recording band a friction force d e relatively low value during contact between them, an element to hold the guide so as to cause the surface of the guide to push the side of the band in cooperative relation with the winch with a force sufficient to produce the advance of the band between the peripheral surface of the winch and the guide surface when the winch is rotated.
