Abstract
Abstract A strip coiler for the winding of coils from rolled metal strip, especially slit or split strip, comprises a coiling drum provided with a longitudinal surface against which a movable jaw can clamp an end of the strip. The surface or the jaw is formed with an elastic clamping material or an elastic clamping jaw, preferably of rubber, and such material is preferably provided on both the surface and the jaw.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
118 words
A strip coiler comprising a drum shaft; at least one drum segment shiftable on said shaft and at least one clamping bar mounted on said shaft and juxtaposed with said segment, said segment and said bar defining a clamping gap between them and having juxtaposed clamping surfaces, the displacement of said segment relative to said bar engaging an end of a strip to be coiled between said surfaces; and at least one elastically compressible member mounted on one of said surfaces for engagement with said strip, said member being formed with a hollow permitting compression of the material of said member without extrusion thereof between said one of said surfaces and said strip upon compression of said member.
Claim 2
Dependent Claim
118 words
A strip coiler comprising a drum shaft; at least one drum segment shiftable on said shaft and at least one clamping bar mounted on said shaft and juxtaposed with said segment, said segment and said bar defining a clamping gap between them and having juxtaposed clamping surfaces, the displacement of said segment relative to said bar engaging an end of a strip to be coiled between said surfaces; and at least one elastically compressible member mounted on one of said surfaces for engagement with said strip, said member being formed with a hollow permitting compression of the material of said member without extrusion thereof between said one of said surfaces and said strip upon compression of said member.
Claim 3
Dependent Claim
17 words
The strip coiler defined in claim 1 wherein the hollow in said member is a transverse bore.
Claim 4
Dependent Claim
26 words
The strip coiler defined in claim 1 wherein said one of said surfaces is formed with a recess accommodating said member and permitting the compression thereof.
Claim 5
Dependent Claim
15 words
The strip coiler defined in claim 1 wherein said member has a ball-like clamping surface.
Claim 6
Dependent Claim
33 words
The strip coiler defined in claim 1 wherein said member is composed of rubber or synthetic elastomer having a higher coefficient of sliding friction than the material of said one of said surfaces.
Claim 7
Dependent Claim
23 words
The strip coiler defined in claim 1 wherein said member has a profile merging with the profile of said one of said surfaces.
Claim 8
Dependent Claim
40 words
The strip coiler defined in claim 1 wherein said member is formed with a foot and said one of said surfaces is provided with an undercut recess receiving said foot for anchoring said member to said one of said surfaces.
Claim 9
Dependent Claim
27 words
The strip coiler defined in claim 1 wherein said surface of said segment is formed as a logarithmic spiral merging with the cylindrical periphery of said segment.
Claim 10
Dependent Claim
20 words
The strip coiler defined in claim 1 wherein at least one such member is provided on each of said surfaces.
Claim 11
Dependent Claim
15 words
The strip coiler defined in claim 9 wherein said members are disposed opposite one another.
Claim 12
Dependent Claim
102 words
A strip coiler comprising a drum shaft; at least one drum segment shiftable on said shaft and at least one clamping bar mounted on said shaft and juxtaposed with said segment, said segment and said bar defining a clamping gap between them and having juxtaposed clamping surfaces, the displacement of said segment relative to said bar engaging an end of a strip to be coiled between said surfaces; and a plurality of elastically compressible members mounted on one of said surfaces for engagement with said strip, said members being spaced apart along said one of said surfaces in at least one row.
Claim 13
Dependent Claim
102 words
A strip coiler comprising a drum shaft; at least one drum segment shiftable on said shaft and at least one clamping bar mounted on said shaft and juxtaposed with said segment, said segment and said bar defining a clamping gap between them and having juxtaposed clamping surfaces, the displacement of said segment relative to said bar engaging an end of a strip to be coiled between said surfaces; and a plurality of elastically compressible members mounted on one of said surfaces for engagement with said strip, said members being spaced apart along said one of said surfaces in at least one row.
Claim 14
Dependent Claim
19 words
The strip coiler defined in claim 11 wherein the hollow in each of said members is a transverse bore.
Claim 15
Dependent Claim
25 words
The strip coiler defined in claim 11 wherein said one of said surfaces is formed with recesses accommodating said members and permitting the compression thereof.
Claim 16
Dependent Claim
17 words
The strip coiler defined in claim 11 wherein each of said members has a ball-like clamping surface.
Claim 17
Dependent Claim
34 words
The strip coiler defined in claim 11 wherein each said member is composed of rubber or synthetic elastomer having a higher coefficient of sliding friction than the material of said one of said surfaces.
Claim 18
Dependent Claim
25 words
The strip coiler defined in claim 11 wherein each of said members has a profile merging with the profile of said one of said surfaces.
Claim 19
Dependent Claim
42 words
The strip coiler defined in claim 11 wherein each of said members is formed with a foot and said one of said surfaces is provided with an undercut recess receiving said foot for anchoring said member to said one of said surfaces.
Claim 20
Dependent Claim
27 words
The strip coiler defined in claim 11 wherein said surface of said segment is formed as a logarithmic spiral merging with the cylindrical periphery of said segment.
Claim 21
Dependent Claim
21 words
The strip coiler defined in claim 11 wherein at least one such member is provided on the other of said surfaces.
Claim 22
Dependent Claim
18 words
The strip coiler defined in claim 19 wherein the members on both surfaces are disposed opposite one another.
