Abstract
Abstract An assembly for rigidly supporting a plurality of wound rolls of tape spliced together to form a continuous usable long yardage tape supply. The assembly comprises a plurality of tape cores which are placed into the wound rolls of tape and fan-shaped tape support members. The support members are secured between adjacent cores and form transition surfaces for the tape from the inside of the first roll to the outer convolution of the next adjacent roll without slack becoming present in the tape.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
103 words
A fabricated long yardage tape support assembly comprising: a plurality of axially aligned tape cores having similar hub constructions and a substantially cylindrical tape supporting surface for supporting a roll of convolutely wound tape, and tape support means disposed between and in fixed relationship with adjacent ones of said cores for forming a transition surface for a length of tape which surface is generally tangential to said tape supporting surface of one core and extends outwardly from said one core to allow a said length of tape to join the outer convolution of a roll of tape on a next adjacent tape core.
Claim 2
Dependent Claim
103 words
A fabricated long yardage tape support assembly comprising: a plurality of axially aligned tape cores having similar hub constructions and a substantially cylindrical tape supporting surface for supporting a roll of convolutely wound tape, and tape support means disposed between and in fixed relationship with adjacent ones of said cores for forming a transition surface for a length of tape which surface is generally tangential to said tape supporting surface of one core and extends outwardly from said one core to allow a said length of tape to join the outer convolution of a roll of tape on a next adjacent tape core.
Claim 3
Dependent Claim
35 words
A tape support assembly according to claim 1 wherein said cores and tape support means are fixed together by locking means provided for locking said cores and tape support means together in a rigid assembly.
Claim 4
Dependent Claim
30 words
A tape support assembly according to claim 2 wherein said locking means affords adjustment of position of the individual tape support means relative to said cores for balancing an assembly.
Claim 5
Dependent Claim
29 words
A tape support assembly according to claim 1 wherein said transition surface has an axial width greater than the axial dimension of said tape supporting surface of said cores.
Claim 6
Dependent Claim
157 words
A fabricated long yardage tape package comprising: a plurality of rolls of radially wound tape with an inner wound portion withdrawn, a plurality of axially aligned tape cores having a substantially cylindrical tape supporting surface inserted in said rolls of tape for supporting the roll of tape, and tape support means disposed between and in fixed relationship with adjacent ones of said cores for forming a transition surface for a length of tape joining the inner wound portion of one roll to the outer convolution of a next adjacent roll of tape, said surface being generally tangential to said tape supporting surface of one core and extending outwardly from said one core to the outer radial convolution of said next adjacent roll of tape to allow said length of tape to join the outer convolution of said next adjacent roll of tape on a next adjacent core to define a continuous length of tape in said rolls.
Claim 7
Dependent Claim
157 words
A fabricated long yardage tape package comprising: a plurality of rolls of radially wound tape with an inner wound portion withdrawn, a plurality of axially aligned tape cores having a substantially cylindrical tape supporting surface inserted in said rolls of tape for supporting the roll of tape, and tape support means disposed between and in fixed relationship with adjacent ones of said cores for forming a transition surface for a length of tape joining the inner wound portion of one roll to the outer convolution of a next adjacent roll of tape, said surface being generally tangential to said tape supporting surface of one core and extending outwardly from said one core to the outer radial convolution of said next adjacent roll of tape to allow said length of tape to join the outer convolution of said next adjacent roll of tape on a next adjacent core to define a continuous length of tape in said rolls.
Claim 8
Dependent Claim
36 words
A tape package according to claim 5 wherein said cores and tape support means are individual members fixed together by locking means for locking said individual cores and tape support means together in a rigid assembly.
Claim 9
Dependent Claim
39 words
A tape package according to claim 6 wherein said transition surface has an axial width greater than the axial dimension of said tape and said surface is smooth and continuous to the outer periphery of said rolls of tape.
Claim 10
Dependent Claim
31 words
A tape package according to claim 5 wherein said transition surface has an axial width greater than the axial dimension of said tape supporting surface of said tape and said cores.
