A magnetic tape wind-up method comprises the steps of winding up a magnetic tape around a hub, which is incorporated in a cassette case, while the magnetic tape is being moved and is in contact with a contact member provided in the cassette case. The magnetic tape is wound up while a gas is being blown against the contact member or against a portion of the magnetic tape, which portion is present in the vicinity of the contact member, in such a way that the gas flows between the contact member and the magnetic tape.

Magnetic tape wind-up method

An apparatus for cleaning the edges of a magnetic tape cut into final-product widths from a wide raw material web with which magnetic powder shed from the tape and base film dust breaking off in the cutting process are removed without damage to the tape. The apparatus includes an air bearing guide for floating the magnetic tape as it is transported thereon, a cleaning device positioned at a side of the guide and making contact with at least one edge of the magnetic tape, and a magnet device for urging the edge of the tape into close contact with the cleaning device.

Cleaning apparatus for magnetic tape

A tape winding device in which a tape is wound onto a reel. A magnetic field is applied to the tape during winding in a direction oblique to the axis of rotation and thus to the tape thickness whereby the tape is evened up to the flange of the reel.

Method and device for winding magnetic tape using magnetic alignment

A magnetic tape winder in which a magnetic tape is wound onto a flanged reel which being subjected to a magnetic field in the width direction of the tape. The reel is fit between the poles of a U-shaped magnet.

A first coating liquid 3 is applied to one surface of a continuously running web 1 and fluidity of the first coating layer is eliminated by an air blower 6, after which the web is float supported over a cylindrical blower 7 by static gas pressure. A second coating liquid 11 is applied to the opposite surface of the web in the vicinity of the float region by a freely falling curtain film 12 or by a pressure extruded jet film 15. sp

Dual surface film coating of running web

In a method for continuously coating with a coating solution a plurality of running webs having discontinuous areas in the surface thereof, the improvement which comprises coarsening at least the surface of the web coated in the area of the web immediately following the discontinuous area of the web prior to the coating. The discontinuous areas in the surface can arise from the tape used to connect one web to another web or from projection in the surface of the web.

Method for coating running webs having projecting splices

A method for applying various coating liquids on the surface of a travelling web, such as plastic films, paper, metallic sheets, etc., with a discontinuity thereon, e.g., due to a connection of pieces of the web comprising preworking a web portion so that the web surface downstream of the discontinuity is coplanar to or higher than the maximum height of the discontinuity, whereby irregularities in coating of liquids are eliminated.
