Abstract
Abstract For use in connection with an underground reel in a rolling mill for band-shaped rolling stock, a two-roll driving device, with an upper driving roll and a lower driving roll which are arranged one above the other. When looking in the direction in which the rolling stock enters the reel, the axle of the upper driving roll is during the entry of the start of the rolling stock into the reel located behind the axle of the lower driving roll and after the start of the band-shaped rolling stock has been grasped by the winding mandrel of the reel the upper driving roll is pivotable into a position vertically above the axle of the lower driving roll, while behind the lower driving roll there is provided a deviating device for the band-shaped rolling stock. The upper driving roll is journalled in a stand which is pivotable about the axis of the lower driving roll and adjustable relative to the latter. A frame supporting the pivotable stand has arranged thereon a horizontally displaceable deviating flap which is movably connected to the stand.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
230 words
For use in connection with an underground reel in a rolling mill for band-shaped rolling stock, a two-roll driving device which includes in combination: frame means, a first driving roll rotatably journalled in said frame means, a stand independently pivotable about the axis of rotation of said first roll, a second roll supported by said stand for rolling cooperation with said first roll, adjusting means supported by said stand and operatively connected to said second roll for selectively adjusting said second roll relative to said first roll, and power operable pivoting means operatively connected to said stand independently to pivot the latter and thereby said second roll from a first position in which said second roll and said first roll have their axes of rotation located in an at least approximately common vertical plane to a second position in which their axes of rotation are located in an at least approximately common inclined plane forming an acute angle with said approximately common vertical plane while that part of said inclined plane which extends through said second roll is located behind said common vertical plane when viewing said driving device in the direction in which said first and second rolls are intended to pass the rolling stock to be rolled therethrough, said second roll also being pivotable by said power operable pivoting means from said second position to said first position.
Claim 2
Dependent Claim
230 words
For use in connection with an underground reel in a rolling mill for band-shaped rolling stock, a two-roll driving device which includes in combination: frame means, a first driving roll rotatably journalled in said frame means, a stand independently pivotable about the axis of rotation of said first roll, a second roll supported by said stand for rolling cooperation with said first roll, adjusting means supported by said stand and operatively connected to said second roll for selectively adjusting said second roll relative to said first roll, and power operable pivoting means operatively connected to said stand independently to pivot the latter and thereby said second roll from a first position in which said second roll and said first roll have their axes of rotation located in an at least approximately common vertical plane to a second position in which their axes of rotation are located in an at least approximately common inclined plane forming an acute angle with said approximately common vertical plane while that part of said inclined plane which extends through said second roll is located behind said common vertical plane when viewing said driving device in the direction in which said first and second rolls are intended to pass the rolling stock to be rolled therethrough, said second roll also being pivotable by said power operable pivoting means from said second position to said first position.
Claim 3
Dependent Claim
63 words
A device in combination according to claim 1, which includes first bearing bodies supported by said frame means for rotatably supporting said first roll, bushing means surrounding said first bearing bodies and also supported by said frame means, bearing means supported by said bushing means and pivotally supporting said stand, and abutment means mounted on said frame means for defining said second position.
Claim 4
Dependent Claim
91 words
A device in combination according to claim 1, in which said second roll has lateral trunnions and in which said device includes bearing means slidably supported by said stand and supporting said trunnions, said adjusting means including fluid operable cylinder piston means mounted on said stand and also including insert members connected to said cylinder-piston means and surrounding said last mentioned bearing means, said device also including wedge members arranged on the outer bottom side of said insert members and further including spindle and motor means for adjusting said wedge members.
Claim 5
Dependent Claim
32 words
A device in combination according to claim 1, in which said power operable pivoting means include fluid operable cylinder-piston means pivotally mounted on said frame means and pivotally connected to said stand.
Claim 6
Dependent Claim
17 words
A device in combination according to claim 4, in which said cylinder piston means are driven synchronously.
Claim 7
Dependent Claim
33 words
A device in combination according to claim 1, in which independently pivotable deviating flap means are provided at least approximately horizontally displaceably arranged in said frame means and movably connected to said stand.
Claim 8
Dependent Claim
60 words
A device in combination according to claim 6, which includes a roller bed roller operatively associated with said deviating flap means, and in which said frame means has an oblong opening for journalling and guiding said roller bed roller for horizontal movement, lever means being pivotally supported by said frame means and being operatively connected to said roller bed roller.
Claim 9
Dependent Claim
92 words
A device in combination according to claim 7, in which said lever means include a first and a second lever, one end of said first lever being pivotally connected to said frame means and the other end of said first lever being pivotally connected to one end of said second lever, the other end of said second lever being operatively connected to said roller bed roller, said second lever being pivotally connected to said frame means at a point between its connection with said roller bed roller and with said first lever.
