Abstract: A cassette system for any type of recording medium in strip or tape form, such as films and magnetic tapes, consists essentially of a housing whose external dimensions match those of a conventional type of cassette, and a protective holder for the recording medium which is wound into at least one roll. The housing and the holder are separate or separable members and can be fitted together. Both are provided with means for inserting the holder into the housing in the correct position, and for introducing the recording medium into the transport apparatus. The housing is provided with opening and closing means. The holder can be designed to be separable from the roll of recording medium. Preferably, the housing is a precision-made article and the holder a low-cost article.

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.
