Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
149 words
A method for making an angle turn in a run of flat cable enclosed in a sealed envelope, comprising the steps of: providing openings into sealed together side margins along a limited length of a sealed envelope which encloses an elongated flat electrical cable, severing across a bottom layer and a top layer of said envelope and across a metal shield layer contained by said envelope, constructing a first angle turn in said cable in a first direction directly opposite to the desired direction of cable turn, folding a first diagonal fold in said cable, constructing a second angle turn in said cable in said desired direction, folding a second fold in said cable, interleaving said metal shield layers, joining together said interleaved metal shield layers, interleaving said bottom layers of said envelope and said top layers of said envelope, and taping shut said openings in said side margins.
Claim 2
Independent Claim
149 words
A method for making an angle turn in a run of flat cable enclosed in a sealed envelope, comprising the steps of: providing openings into sealed together side margins along a limited length of a sealed envelope which encloses an elongated flat electrical cable, severing across a bottom layer and a top layer of said envelope and across a metal shield layer contained by said envelope, constructing a first angle turn in said cable in a first direction directly opposite to the desired direction of cable turn, folding a first diagonal fold in said cable, constructing a second angle turn in said cable in said desired direction, folding a second fold in said cable, interleaving said metal shield layers, joining together said interleaved metal shield layers, interleaving said bottom layers of said envelope and said top layers of said envelope, and taping shut said openings in said side margins.
Claim 3
Dependent Claim
28 words
The method as recited in claim 1, and further including the step of: securing said taped shut side margins to a floor against which said cable is routed.
Claim 4
Dependent Claim
118 words
An angle turn in an assembly of a flat cable enclosed together with a metal shield layer in a sealed envelope, comprising: side margins of said envelope having openings therein, said envelope being transversely severed through defining free end sections, said metal shield being transversely severed through defining free end sections thereof, said cable having a first creased fold and a second creased fold defining stacked sections of said cable overlying one another, said free end sections of said metal shield being interleaved and joined together, said free end sections of said envelope being interleaved and covering said sections of said cable and said sections of said metal shield, and means sealing said openings in said side margins.
Claim 5
Dependent Claim
118 words
An angle turn in an assembly of a flat cable enclosed together with a metal shield layer in a sealed envelope, comprising: side margins of said envelope having openings therein, said envelope being transversely severed through defining free end sections, said metal shield being transversely severed through defining free end sections thereof, said cable having a first creased fold and a second creased fold defining stacked sections of said cable overlying one another, said free end sections of said metal shield being interleaved and joined together, said free end sections of said envelope being interleaved and covering said sections of said cable and said sections of said metal shield, and means sealing said openings in said side margins.
Claim 6
Dependent Claim
29 words
The structure as recited in claim 3, wherein, said means comprises adhesive tape covering and securing said side margins to a floor over which said cable assembly is routed.
