Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
123 words
A reel for wires, cables and the like which are to be placed into an annealing device, comprising a pair of mirror-symmetrical reel sections each having a hub portion and a flange portion, said hub portions abutting one another axially and each having a center passage extending axially of said reel and further including an outer and an inner annular wall surrounding said center passage and defining between themselves an annular space which conically diverges towards and is open at the respectively associated flange portion; radially extending reinforcing ribs provided in said annular spaces; axially extending reinforcing ribs on each of said flange portions; and nut-and-bolt connectors in said annular spaces and connecting said hub portions with one another in axially aligned condition.
Claim 2
Dependent Claim
123 words
A reel for wires, cables and the like which are to be placed into an annealing device, comprising a pair of mirror-symmetrical reel sections each having a hub portion and a flange portion, said hub portions abutting one another axially and each having a center passage extending axially of said reel and further including an outer and an inner annular wall surrounding said center passage and defining between themselves an annular space which conically diverges towards and is open at the respectively associated flange portion; radially extending reinforcing ribs provided in said annular spaces; axially extending reinforcing ribs on each of said flange portions; and nut-and-bolt connectors in said annular spaces and connecting said hub portions with one another in axially aligned condition.
Claim 3
Dependent Claim
42 words
A reel as defined in claim 1, said hub portions each having an axial endface facing the corresponding endface of the other hub portion; and wherein said endfaces are provided with interengaging profiles for preventing relative radial displacement of said hub sections.
Claim 4
Dependent Claim
26 words
A reel as defined in claim 2, wherein said endfaces each comprise at least one of said profiles, and wherein the latter are of annular outline.
Claim 5
Dependent Claim
