Abstract
Abstract A guide means for tapes to be transported, in particular in tape cassettes or tape apparatus, comprises a support element and a flexible guide strip, in particular one made of metal foil, fixed on this, and at least one holding element for the end sections of the flexible guide strip. The guide strip possesses a predetermined thickness and may be drop-shaped or pear-shaped in the operating position. The tape guide means may also comprise a support element whose surface is at least partially cylindrical and a flexible guide strip which is fastened thereon. As a separable unit which can be preassembled, the tape guide means can therefore also be employed for automatic manufacture. The tape guide means can be used for tape guides which are either stationary or movable within limits, in the field of tape-like recording media, such as films, magnetic tapes, punched tapes, etc.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
128 words
Guide means for a tape to be transported, in particular in a magnetic tape cassette, consisting of a flexible guide strip which is stationary on an at least partly dimensionally stable support element having an at least partly cylindrical surface as a guide surface for the tape, said flexible guide strip having a length greater than that of the peripheral contour of the support element, said flexible guide strip having projecting end sections and a thickness of not more than 150 μm, so that the shape of the guide surface is determined primarily by the shape and surface of the support element, and by a slotted cylindrical element for holding said projecting end sections as to prevent turning at the flexible guide strip relative to the support element.
Claim 2
Dependent Claim
128 words

Claim 3
Dependent Claim
21 words
Tape guide means as claimed in claim 1, wherein the flexible guide strip is from about 10 to 50 μm thick.
Claim 4
Dependent Claim
17 words
Tape guide menas as claimed in claim 1, wherein the guide strip consistas of a springy material.
Claim 5
Dependent Claim
24 words
Tape guide means as claimed in claim 1, wherein the guide strip is held by being jammed onto the support element and/or holding element.
Claim 6
Dependent Claim
23 words
Tape guidemeans as claimed in claim 1 wherein the flexible guide strip is shaped so that it has an omega form in cross-section.
Claim 7
Dependent Claim
128 words
Guide mean for a tape to be transported, in particular in a magnetic tape cassette, consisting of a flexible guide strip which is stationary on an at least partly dimensionally stable support element having an at least partly cylindrical surfce as a guide surface for the tape, said flexible guide strip having length greater than that of the peripheral contour of the support element, said flexible guide strip having projecting end sections and a thickness of not more than 150 μm, so that the shape of the guide surface is determined primarily by the shape and surface of the support element, and by two spaced apart projections arranged to hold said projecting end sections as to prevent turning of the flexible guide strip relative to the support element.
Claim 8
Dependent Claim
128 words

Claim 9
Dependent Claim
172 words
Guide means for a tape to be transported, in particular in a magnetic tape cassette, consisting of a flexible guide strip which is stationary on an at least partly dimensionally stable support element having an at least partly cylindrical surface and forming the guide surface for the tape, said flexible guide strip having a length greater than that of the peripheral contour of the support element, said flexible guide strip having projecting end sections and a thickness of not more than 150 μm, so that the shape of the guide surface is determined primarily by the shape and surface of the support element, and by at least one dimensionally stable holding element having a slot or groove provided to hold said projecting end sections of the flexible guide strip which are connected together so a to prevent turning of the flexible guide strip relative to the support element, the end sections of the flexible strip are connected in such a way that each end section is curved away from its longitudinal axis.
