摘要:
In manufacturing a magnetic tape, a long web of non-magnetic base material is coated with a magnetic layer and, thereafter, subjected to a smoothing process, wherein the surface of the magnetic layer is abraded, ground, and then wiped out. For grinding, sapphire blades are kept in contact with the surface of the magnetic layer with their edges oriented in a transverse direction to the magnetic tape, and are moved back and forth in the transverse direction to the magnetic tape, while the magnetic tape is being conveyed in a lengthwise direction of the magnetic tape. Of the sapphire blades, adjacent two are moved in opposite directions to each other.

A peeling apparatus may include a frame, a set of mounts being removably connected to a first end of the frame adjacent at least one first roller opening and each mount including a flange bearing. The peeler may also include a set of abrasive rollers being arranged to define a peeling chamber and having first ends rotatably supported by flange bearings of the mounts so that the abrasive rollers are installable or removable through the at least one first roller opening upon removal of the respective mounts from the frame. The peeling apparatus may also include a set of roller drive motors for respective abrasive rollers that are also carried by respective mounts. A second set of flange bearings may be provided at the opposite end of the chamber. A high capacity embodiment includes dual peeling chambers and wherein feeders in the form of augers rotate in opposite directions.
