Pivotally Mounted Roller Patents (Class 226/21)
  • Patent number: 3985276
    Abstract: A guide roll apparatus for use in a metal strip processing line wherein it is desirable that the longitudinal centerline of the strip remains coincident with the centerline of the strip processing line.The guideroll apparatus is compact in design so that it may be located in a strip processing line where prior steering rolls would not fit. The apparatus comprises a pair of rolls so disposed that the strip passes over a portion of one roll, then between the rolls and over a portion of the other roll, on its path of travel in the processing line. Each of the two rolls is mounted for tilting movement, and mechanism between the rolls causes the rolls to tilt in opposite directions in the same amount.

  • Patent number: 3973446
    Abstract: A device for maintaining a predetermined alignment of a running web and more particularly maintaining the alignment of the belt of an endless conveyor comprising an idler spool over which the web or belt passes and which is laterally movable relative to its supporting framework. Means are provided for lifting one end of the idler spool and lowering the other in response to the lateral shifting of the belt and spool from a predetermined aligned position to cause the spool and the belt to again seek the predetermined aligned position.

  • Patent number: 3966105
    Abstract: A web aligning apparatus is disclosed wherein a web path correcting tilt frame is mounted for tilting movement between the laterally spaced side plates of the tilt frame support structure. The tilt frame includes a pair of laterally spaced frame members which extend generally longitudinally of the path of travel of the web through the apparatus and which rotatably support a pair of steering rollers therebetween. The axes of the steering rollers extend generally transversely to the path of travel of the web through the apparatus. A pair of elongated links respectively connect the tilt frame members with the support structure side plates and are arranged so that the instantaneous center of rotation of the tilt frame is located outside the perimeter of the tilt frame and shifts along an arcuate path that extends laterally of the path of travel of the web with tilting movements of the tilt frame.

  • Patent number: 3958736
    Abstract: Simultaneously tensioning one side of a web and correcting steering error introduced by said tensioning comprising passing the web partially around a tensioning member, e.g. a roll, and skewing the roll axis relative to a neutral axis, with the end of the roll adjacent the side of the web to be tensioned positioned, relative to the other end of the roll, toward the portion of the web wrapped around the roll and forward in the direction of web movement.

  • Patent number: 3942696
    Abstract: Apparatus for controlling lateral divergence or displacement of a web from its true path, which requires contact of its rollers with one face only of the web, and which does not impose deflection of the path of the web.
