摘要： The perpendicular magnetic orientation of a magnetic layer containing platelet-form ferromagnetic particles coated on a web support is effectively performed by passing a web having thereon the coated magnetic layer in an undried state through a magnetic field formed by plural pairs of opposite pole type magnets disposed in the travelling direction of the web with a gap between adjacent pairs of magnets, while supplying drying air through each gap onto the surface of the travelling web to substantially complete the drying of the coated layer while the web is in the magnetic field. A partition may be inserted in each gap so that the lower end of the partition is close to the upper surface of the travelling web to divide the gap into a front section and a back section, and the drying air may be passed through these sections.

摘要： A method of producing a magnetic recording medium comprises forming a magnetic layer by applying a magnetic film forming liquid onto a continuously running non-magnetic support, applying a magnetic field onto the magnetic film forming liquid before the magnetic film forming liquid has dried, and then drying the magnetic film forming liquid. A non-magnetic undercoating layer is formed on the support simultaneously with the step of forming the magnetic layer by simultaneously applying to the support a non-magnetic undercoating forming liquid and the magnetic film forming liquid. The magnetic field is applied before both the magnetic film forming liquid and non-magnetic undercoating forming liquid have dried.

摘要： A method and apparatus for removing particles from a flexible sheet. The sheet is run over a rotating rod, rotating oppositely to the moment of the sheet. The rod is immersed on its lower side in a bath of solvent and excess solvent is removed from the bath and is filtered. Additionally, solvent may be applied to the sheet before it reaches the rotating rod or a negative pressure applied just upstream of the rod sucks away the particles.

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.
