Abstract
Abstract A tape, for example a record tape, is clamped onto a core by a clip which embraces the core. Between peripherally spaced ends of the clip, a core portion extends outwardly, by a radial distance approximately equal to the thickness of the clip, to provide a substantially cylindrical support surface for the tape to be wound onto the core and clip.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
178 words
A tape carrier, particularly for carrying recording tapes, comprising a resilient clip of generally circular cross-section having a longitudinal axis and a first outer circumferential surface formed with an axial slot extending parallel to said axis, and bounded by edge portions of said clip; and a core body having a second outer circumferential surface and being adapted to be received within the confines of said clip by a snapping action so that an end portion of the tape may be clamped intermediate said second outer circumferential surface and said clip, said core body comprising a rib portion, having an arcuate surface portion and being received in said slot intermediate said edge portions, said rib portion projecting outwardly from said core body to an extent so as to form a substantially circumferentially complete configuration with said first outer circumferential surface, whereby the tape adjacent said clamped end portion which has been passed between said rib portion and one of said edge portions is passed over said arcuate surface portion in a smooth and continuous manner without pressuremarking the tape.
Claim 2
Dependent Claim
178 words
A tape carrier, particularly for carrying recording tapes, comprising a resilient clip of generally circular cross-section having a longitudinal axis and a first outer circumferential surface formed with an axial slot extending parallel to said axis, and bounded by edge portions of said clip; and a core body having a second outer circumferential surface and being adapted to be received within the confines of said clip by a snapping action so that an end portion of the tape may be clamped intermediate said second outer circumferential surface and said clip, said core body comprising a rib portion, having an arcuate surface portion and being received in said slot intermediate said edge portions, said rib portion projecting outwardly from said core body to an extent so as to form a substantially circumferentially complete configuration with said first outer circumferential surface, whereby the tape adjacent said clamped end portion which has been passed between said rib portion and one of said edge portions is passed over said arcuate surface portion in a smooth and continuous manner without pressuremarking the tape.
Claim 3
Dependent Claim
21 words
A tape carrier as defined in claim 1, wherein said core body and said rib portion are integral with one another.
Claim 4
Dependent Claim
25 words
A tape carrier as defined in claim 1, wherein said clip and said core portion have cylindrical-segmental outer peripheral surfaces of substantially the same radius.
Claim 5
Dependent Claim
20 words
A tape carrier as defined in claim 1, wherein said clip extends circumferentially more than 180 degrees about said axis.
Claim 6
Dependent Claim
28 words
A tape carrier as defined in claim 1, wherein said clip is radially engageable under adjustable tension with said end portion of the tape on said core body.
Claim 7
Dependent Claim
20 words
A tape carrier as defined in claim 2, including flange means secured to and radially extending from said core body.
Claim 8
Dependent Claim
39 words
A tape carrier as defined in claim 2, wherein said core body has a coaxial bore extending outwardly into said rib portion to form a groove therein, and has a substantially uniform wall thickness around said bore and groove.
Claim 9
Dependent Claim
18 words
A tape carrier as defined in claim 1, wherein said clip substantially consists of soft, elastic, synthetic plastic.
Claim 10
Dependent Claim
26 words
A tape carrier as defined in claim 1, wherein said core body and said rib portion are integral with one another and consist of synthetic plastic.
