Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
202 words
Apparatus for conveying strip coils, comprising: (a) a rolling mill having an uncoiler at the entrance side and a coiler at the exit side, (b) an elongated shelf storage accessible for insertion and removal of coils from both sides, (c) coil-moving equipment consisting of two spaced, parallel, long roller conveyors joined at their ends by short cross conveyors to form an elongated closed plane figure whose long dimension is parallel to and spaced from the roll pass line of the mill, said two long roller conveyors consisting of a first long conveyor for moving coils away from the shelf storage and a second long roller conveyor for moving coils toward the shelf storage, (d) a track with a car extending from the first long roller conveyor to the uncoiler, (e) a track with a car extending from the coiler to the first long roller conveyor at a point downstream of the first conveyor, (f) loading means extending along one side of the shelf storage for inserting a coil into the shelf storage, and (g) unloading means extending along the other side of the shelf storage for removing a coil from the shelf storage and delivering it to the first long roller conveyor.

Claim 3
Dependent Claim
19 words
Apparatus as recited in claim 1, wherein the second long roller conveyor contains a turntable for . coils 180
Claim 4
Dependent Claim
47 words
Apparatus as recited in claim 1, wherein said shelf storage is arranged in two parallel rows, each row provided with conveyor means for inserting a coil and conveyor means for removing a coil, said apparatus comprising tracks with coil carrying cars associated with each shelf storage row.
Claim 5
Dependent Claim
26 words
Apparatus as recited in claim 1, wherein the first long roller conveyor contains a turntable adjacent the shelf storage for receiving coils from the unloading means.
Claim 6
Dependent Claim
28 words
Apparatus as recited in claim 1, wherein the rolling mill comprises a plurality of roll stands arranged in a roll pass line extending between the coiler and uncoiler.
Claim 7
Dependent Claim
102 words
Apparatus as recited in claim 1, wherein said elongated shelf storage comprises a primary shelf storage and said apparatus comprises: (a) a secondary elongated shelf storage including loading and unloading equipment spaced from and extending parallel to said primary shelf storage, (b) annealing furnaces, the longitudinal axes of which extend perpendicular to the longitudinal axis of the secondary shelf storage, (c) means for loading coils into and unloading coils from the annealing furnaces, and (d) means for conveying coils from the coil moving equipment to the secondary shelf storage and from the secondary shelf storage to the furnace loading and unloading means.
Claim 8
Dependent Claim
65 words
Apparatus as recited in claim 6, wherein the furnace loading and unloading means comprises: (a) tracks located in the front of the annealing furnace openings and extending perpendicular to the axes of the furnace, and means for conveying coils from the secondary shelf storage, (b) a loading and unloading car on the tracks, and (c) racks for receiving coils and for transport on the car.
