Abstract: A process for preparing a magnetic recording medium utilizing an improved coating method. This coating method includes steps of coating a solvent of the same composition as that used in preparation of a magnetic coating solution or one compatible therewith on a continuously running non-magnetic support to prepare a precoat layer of the solvent, and then coating the magnetic recording solution on the precoat layer while the precoat layer is wet. This improved coating method prevents air from being entrained in the magnetic recording solution and thus permits to produce a very thin magnetic recording layer to be formed on the support with high efficiency.

A slot through which coating solution is supplied emerges between a doctor edge surface and a rear edge surface. The doctor edge surface is smoothly curved, and an exit end point B of the slot at the rear edge surface is located in a position that satisfies the relation .theta..sub.1 <.theta..sub.2 <180.degree., where .theta..sub.1 is an angle formed by a tangential line drawn to the rear edge surface at the point B and a tangential line drawn to the doctor edge surface at a point A at a downstream end of the doctor edge surface, and .theta..sub.2 is an angle formed by the tangential line drawn to the rear edge surface at the point B and a tangential line drawn from the point B to the doctor edge surface.

Abstract: An apparatus for removing foreign matter from a flexible support such as a photographic film or magnetic tape. After applying a solvent to the surface of the support from which the foreign matter is to be removed, the support is passed over at least two parallel adjacent plates which extend widthwise perpendicular to the direction of movement of the support, with the plates being located relative to the support at a position before the solvent evaporates. The edge surface of the downstream one of the two plates is provided with a cutting edge at the upstream side thereof. The cutting edge forms a gap with the surface sufficiently small that the foreign matter to be removed cannot enter the gap. Further, the gap is large enough to leave solvent film in a thickness of at least 0.2 microns after passing the two plates.

A mechanically actuated cap applying head is mounted for vertically reciprocating movement so as to apply a downwardly directed capping force on the bottle. A hand manipulated dual position stop mechanism limits the downwardly directed capping force in one mode to accommodate semirigid containers and in the other mode removes the downward force restraint for capping glass bottles.

Abstract: An extrusion type coating apparatus for applying a coating film to a support has a bent doctor edge made of cemented carbide having a very large hardness. The bent doctor edge has a very large obtuse angle and the resulting doctor edge allows the coating film to be applied smoothly to the support. Since the doctor edge is made of cemented carbide having a very high hardness, the doctor edge is not unduly worn by abrasives contained in the coating film thereby improving the wear-resistance of the apparatus.
