Abstract
Abstract A device particularly for guiding wire rod leaving a rolling mill in horizontal direction and directed to a coiler of vertical axis. The device comprises a first disc provided with a peripheral groove, the disc being movable in contact with the wire rod along a substantial portion of the path thereof, having substantially its peripheral speed equal to the advancement speed of the wire rod. A second rotatable disc is provided tangential to the first disc at the point of exit of the wire rod from the first disc. The device is further provided with a unit for synchronising the speeds of the first disc and the second disc with the speed of the wire rod. The speed synchronising unit principally comprises a transmission unit of gear wheel type which has the same number of speed steps as the number of advancement speeds provided for the wire rod.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
184 words
A device for guiding hot wire rod at the outlet of a rolling mill from which the wire rod comes out in a substantially horizontal direction to a coiler having an axis forming an angle with said substantially horizontal direction, the device comprising movable guide means arranged between the rolling mill outlet and the coiler and contacting the wire rod along at least an arcuate path thereof extending tangentially to said substantially horizontal direction and said axis, and means for driving said movable guide means in contact with the wire rod at a spead substantially equal to that of the wire rod between the rolling mill outlet and the coiler, wherein said guide means include at least one peripherally grooved guiding disc having a radius substantially equal to the radius of curvature of said arcuate path and at least a second rotatable disc having a peripheral groove and a radius substantially less than that of said guiding disc, said second disc being arranged substantially tangential to said guiding disc and being rotated at a peripheral speed substantially equal to that of said guiding disc.
Claim 2
Independent Claim
184 words
A device for guiding hot wire rod at the outlet of a rolling mill from which the wire rod comes out in a substantially horizontal direction to a coiler having an axis forming an angle with said substantially horizontal direction, the device comprising movable guide means arranged between the rolling mill outlet and the coiler and contacting the wire rod along at least an arcuate path thereof extending tangentially to said substantially horizontal direction and said axis, and means for driving said movable guide means in contact with the wire rod at a spead substantially equal to that of the wire rod between the rolling mill outlet and the coiler, wherein said guide means include at least one peripherally grooved guiding disc having a radius substantially equal to the radius of curvature of said arcuate path and at least a second rotatable disc having a peripheral groove and a radius substantially less than that of said guiding disc, said second disc being arranged substantially tangential to said guiding disc and being rotated at a peripheral speed substantially equal to that of said guiding disc.
Claim 3
Dependent Claim
38 words
A device as claimed in claim 1, in which said guiding disc is arranged tangentially to the direction of exit of the wire rod from the rolling mill and to the direction of the axis of the coiler.
Claim 4
Dependent Claim
88 words
A devicE as claimed in claim 1, further comprising a unit for synchronising the peripheral speed of said guiding disc and said second disc with the outlet speed of the wire rod coming out of the rolling mill, said unit including transmission means between the driving means of the rolling mill and said discs, said transmission means including a gearbox for providing a number of a peripheral speeds for said discs as the number of outlet speeds provided for the wire rod coming out of the rolling mill.
Claim 5
Dependent Claim
39 words
A device as claimed in claim 1, comprising driving means for driving said guiding disc and said second disc at a peripheral speed slightly greater than the outlet speed of the wire rod coming out of the rolling mill.
