Abstract: Apparatus for producing a magnetogram carrier, comprising a device for applying one or more layers of a magnetic dispersion to a carrier web (1) and a control magnet arrangement (2), displaceably mounted between the applying device and a drying device for the coated carrier web, for aligning the magnetically anisotropic magnetic particles in the magnetic dispersion in a preferred direction parallel to the plane of the carrier web.

Abstract: The magnetic tape coating machine has the sheet (7) from which the tapes will be cut passing around a drive roller (6) under a container (13) holding the coating substance. An applicator lip distributes the substance onto the sheet as it travels towards a spreader bar (2). This is supported in a block (4) with a height adjusting screw (5) on top. The spreader bar (2) has an elastic rubber layer (3) around it and between this layer (3) and the sheet (7) is a foil. In another design, instead of a circular bar, two rectangular bars are used, which press down on a rubber sheet which in turn rests on the foil.
