    摘要: A method and apparatus for coating a magnetic liquid onto a moving substrate to form a magnetic recording medium having an improved product yield and reduced streaking. Coating liquid is fed to an extruder by a second pump, while excess coating liquid is extracted from the extruder and returned to a storage tank with a second pump. When the coating operation is to be stopped, the extruder is bypassed between the first and second pumps and a portion of the output from the first pump is returned directly to the storage tank so that the flow rates through both pumps are the same during coating and idling times.

    摘要: A method of simultaneously applying a plurality of liquids to a carrier to form respective layers thereon without causing a chromatic nonuniformity or longitudinal streaking in the layers, and to thus stably manufacture a magnetic recording medium of good magnetic recording properties. Liquids containing organic solvents are simultaneously applied to a continuously moving nonmagnetic carrier by an application head of the extrusion type so as to form respective plural layers on the carrier to manufacture a magnetic recording medium. The difference between the viscosities of the liquids present in the slots of the application head and which are to be applied to the carrier to form at least mutually adjacent ones of the layers is set at 50 cp or less, or the difference between the viscosities of the liquids present in the pockets of the application head or is set at 500 cp or less.

    摘要: A coating method and an extrusion-type coating head in which turbulence at the junction between two flows of coating materials is prevented to provide multi-layer simultaneous coating over a wide range of coating rates and with a good coating quality. An intermediate block is sandwiched between a rear block defining a back edge and a front block defining a doctor edge. Two coating flows pass through slits formed on either side of the intermediate block, joining at the top end of the intermediate block and flowing together into a short slot extending between the end of the intermediate block and the outlet of the head.
