Abstract: A laying has a quill rotatable about an axis, and a pipe carried on the quill. The pipe has an entry end arranged to receive a product, and an intermediate portion defining a curved guide path leading from the entry and to a delivery end spaced radially from the quill axis and from which the product is discharged as a helical series of rings. A guide defines a helical extension of the guide path, and comprises a helical support plate projecting outwardly from the quill. A plurality of channel-shaped guide sections supported end to end on the support plate. The guide sections form a segmented radially outwardly facing helical trough surrounded by a cylindrical shroud that cooperates with the guide sections to definee radially and axially confined helical extension of the guide path.

Abstract: Disclosed is an annular roll for use in combination with a roll shaft having a tapered portion and an end portion, the roll surrounding the tapered shaft portion and having circumferentially spaced keys in an outer face thereof, an abutment engageable with an inner face of the roll to axially locate the roll on the roll shaft, a tapered sleeve axially received in a tightly wedged position betrween the roll and the tapered portion of the roll shaft, an axially shiftable drive ring connected to the sleeve and spline to the shaft for rotation therewith, the drive ring having lugs rotatably interengaged with the keys on the outer face of the roll, a first retainer engageable with the outer face of the roll to axially urge the roll against the abutment, and a second retainer engageable with and acting through the drive ring to prevent axial removal of the sleeve from between the roll and the tapered portion of the roll shaft, a tool for axially shifting the tapered sleeve into and out of its wedged position betwee

Abstract: A rolling mill roll assembly includes a roll shaft having a tapered portion located adjacent to an end portion. An annular tungsten carbide work roll is received on the tapered shaft portion. The work roll has circumferentially spaced keys integrally formed on its outer face. A tapered sleeve is axially wedged between the work roll and the tapered shaft portion. A drive ring is connected to the sleeve. The drive ring is splined to the shaft end portion and is provided with lug members which are axially received between and which are rotatably engaged with the keys on the outer roll face. Driving torque is thus transmitted from the shaft to the roll via the driving ring, with the roll being concentrically located with respect to the shaft axis by the tapered sleeve.

Abstract: A compact rolling mill has a housing structure divided into a plurality of rolling bays by rigidly interconnected posts extending transversally across the rolling line. Each rolling bay has a window facing a common side of the mill. The rolling bays are adapted to contain roll packages, with each such package including a pair of work rolls straddle mounted between bearings arranged in bearing chocks. The roll packages are movable, either singly or as a group, in a common lateral direction through the windows, between operative rolling positions supported by the housing posts within the rolling bays, and extracted inoperative positions on the aforesaid common side of the mill.

Abstract: A rolling mill laying pipe has a rigid external tube with an entry end for receiving a longitudinally moving mill product and an exit end through which the product is discharged. An intermediate portion of the tube between the entry and exit ends has a three-dimensionally curved configuration. A helical spring is axially received in and is radially confined by the tube. The spring is relatively tightly wound, with an inside diameter appropriately dimensioned to accommodate passage therethrough of the mill product. Retainer elements are provided at the tube ends for axially confining the spring within the tube. At least one of the retainer elements is detachable to permit removal and replacement of the spring.
