Abstract: A process for the manufacture of a jacket, comprising two cover sheets joined to one another, for a flexible disk for data recording, the cover sheets and the nonwoven lining being punched out in the form of blanks including the functional apertures, and the cover sheet blank and the nonwoven blank being joined to one another and then folded to form the jacket, wherein the sheet material for the cover sheets is transferred from a magazine, with the aid of mechanical, air-operated grippers provided with positioning means, to an assembly surface and is there provided, the sheet of nonwoven material from a second magazine is tacked onto the cover sheet material by spot-welding and is then joined thereto over the entire surface by thermal welding, thereafter the cover sheet material thus provided with the nonwoven covering is transferred to a holder frame and then conveyed, with this frame, to a punching device where it is punched out to form a blank provided with the functional apertures, subsequently the blank is removed from the holder frame by means of mechanical, air-operated grippers and is placed in the correct position on a carrier and folded to form the jacket, and at the same time the folds are stabilized by heating and subsequently cooling the material in the region of the folds, and the surface which come into contact on folding are welded to one another in the marginal portions of the jacket.

Abstract: Magnetic recording media in which, following application of the magnetic dispersion to a web of tape base material, the magnetic particles are oriented in a preferred direction and the magnetic dispersion is dried to fix the magnetic particles in their oriented position. To assist the orienting action of the orientation magnet, a blanket is located between the latter and the coating device, which blanket is caused to make sliding contact with the applied magnetic layer.

Abstract: Apparatus for producing a magnetogram carrier, comprising a device for applying one or more layers of a magnetic dispersion to a carrier web (1) and a control magnet arrangement (2), displaceably mounted between the applying device and a drying device for the coated carrier web, for aligning the magnetically anisotropic magnetic particles in the magnetic dispersion in a preferred direction parallel to the plane of the carrier web.
