Abstract
Abstract A tape record adapted to be coiled to form a roll thereof between the flanges of a support reel wherein the tape record comprises an information portion and terminal end portions. The tape record is characterized by means imparting resilient lateral compliance to at least one of the end portions to permit resilient reduction in the width occupied by the end portion when pressed between the flanges of a support reel thereby retaining the laterally reduced end portion between the flanges. More generally, a reel of pliable tape is provided comprising a cylindrical hub having flanges carried by the ends of the hub. A pliable tape record is wrapped about the hub between the flanges. The record has an information portion and a terminal end portion. The reel is characterized by resilient means yieldingly retaining engagement between the side edges of the end portion and the flanges.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
204 words
A pliable tape record adapted to be coiled to form a roll thereof about the hub of and between the flanges of a support reel, said tape record comprising an informaTion portion and a terminal end portion, said terminal end portion corresponding in length substantially to the circumference of said hub, said tape record being characterized by means imparting resilient lateral compliance in the plane of and substantially throughout the length of said end portion to permit resilient reduction in the width occupied by said end portion throughout said length when pressed between the flanges of a support reel and disposed in pressing relationship against said flanges thereby to retain said end portion between said flanges, wherein said end portion comprises a lattice of perforations each formed of sufficient length and width and disposed in longitudinally offset rows with respect to each other and distributed along said end portion to render said lattice laterally compressible along said end portion, the side edges of said end portion being uniformly more widely spaced substantially throughout the length of said end portion than the spacing between the edges of said information portion so as to substantially, uniformly apply compression throughout a corresponding length of said end portion.
Claim 2
Dependent Claim
204 words
A pliable tape record adapted to be coiled to form a roll thereof about the hub of and between the flanges of a support reel, said tape record comprising an informaTion portion and a terminal end portion, said terminal end portion corresponding in length substantially to the circumference of said hub, said tape record being characterized by means imparting resilient lateral compliance in the plane of and substantially throughout the length of said end portion to permit resilient reduction in the width occupied by said end portion throughout said length when pressed between the flanges of a support reel and disposed in pressing relationship against said flanges thereby to retain said end portion between said flanges, wherein said end portion comprises a lattice of perforations each formed of sufficient length and width and disposed in longitudinally offset rows with respect to each other and distributed along said end portion to render said lattice laterally compressible along said end portion, the side edges of said end portion being uniformly more widely spaced substantially throughout the length of said end portion than the spacing between the edges of said information portion so as to substantially, uniformly apply compression throughout a corresponding length of said end portion.
Claim 3
Dependent Claim
189 words
A pliable tape record adapted to be coiled to form a roll thereof about the hub of and between the flanges of a support reel, said tape record comprising an information portion and a terminal end portion, said tape record being characterized by means imparting resilient lateral compliance in the plane of and substantially throughout the length of said end portion to permit resilient reduction in the width occupied by said end portion throughout said length when pressed between the flanges of a support reel and disposed in pressing relation against said flanges thereby to retain said end portion between said flanges, said end portion including a lattice of perforations each formed of sufficient length and width and disposed in longitudinally offset rows with respect to each other and distributed along said end portion to render said lattice laterally compressible along said end portion, the side edges of said end portion being uniformly more widely spaced substantially throughout the length of said end portion than the spacing between the edges of said information portion so as to substantially, uniformly apply compression throughout a corresponding length of said end portion.
Claim 4
Dependent Claim
189 words
A pliable tape record adapted to be coiled to form a roll thereof about the hub of and between the flanges of a support reel, said tape record comprising an information portion and a terminal end portion, said tape record being characterized by means imparting resilient lateral compliance in the plane of and substantially throughout the length of said end portion to permit resilient reduction in the width occupied by said end portion throughout said length when pressed between the flanges of a support reel and disposed in pressing relation against said flanges thereby to retain said end portion between said flanges, said end portion including a lattice of perforations each formed of sufficient length and width and disposed in longitudinally offset rows with respect to each other and distributed along said end portion to render said lattice laterally compressible along said end portion, the side edges of said end portion being uniformly more widely spaced substantially throughout the length of said end portion than the spacing between the edges of said information portion so as to substantially, uniformly apply compression throughout a corresponding length of said end portion.
Claim 5
Dependent Claim
163 words
A pliable tape record adapted to be coiled to form a roll thereof about a cylindrical hub of predetermined circumference, said tape record including an information portion of uniform thickness and an elongate pliable terminal end portion fixed in end-to-end relation to said information portion and adapted to be wrapped about the circumference of said hub, the thickness of said end portion being tapered to gradually increase in a direction starting from the endmost edge and leading rearwardly, said end portion being of a thickness adjacent said information portion greater than the thickness of said information portion defining an abrupt step having a height corresponding substantially to the thickness of said endmost edge, said step being displaced from said endmost edge a distance corresponding substantially to said circumference of said cylindrical hub to provide for coiling said information portion thereover without abrupt changes in radius so as to eliminate end-of-roll bump or bulge as the roll of tape is wound upon the hub.
Claim 6
Dependent Claim
163 words
A pliable tape record adapted to be coiled to form a roll thereof about a cylindrical hub of predetermined circumference, said tape record including an information portion of uniform thickness and an elongate pliable terminal end portion fixed in end-to-end relation to said information portion and adapted to be wrapped about the circumference of said hub, the thickness of said end portion being tapered to gradually increase in a direction starting from the endmost edge and leading rearwardly, said end portion being of a thickness adjacent said information portion greater than the thickness of said information portion defining an abrupt step having a height corresponding substantially to the thickness of said endmost edge, said step being displaced from said endmost edge a distance corresponding substantially to said circumference of said cylindrical hub to provide for coiling said information portion thereover without abrupt changes in radius so as to eliminate end-of-roll bump or bulge as the roll of tape is wound upon the hub.
