Abstract: A rider roll structure is provided by a beam with at least a pair of rider rolls mounted thereon with adjacent ends of the rolls being mounted in a bearing assembly wherein shafts extending from each adjacent end of each roll are provided at their axial ends with a land and groove configuration so that the lands formed on one shaft are received in the grooves formed on the other and a resilient member is received within the grooves and is shaped so that it extends between mating land areas so that drive from one roll to the other is through the resilient member and the resilient member can accommodate slight angles between the axes of rotation of the rolls. A sleeve surrounds the shaft and the resilient member is keyed to this sleeve which in turn is mounted in a bearing that is mounted on the rider roll beam.

Abstract: A rider roll beam is mounted in a pair of opposed frames having substantially vertical guide surfaces and the axial ends of the beam are provided with curved surfaces cooperating with the vertical guide surfaces to permit the beam to pivot about a horizontal axis located at about the midpoint of the machine and extending substantially perpendicular to the longitudinal axis of the beam. The rider roll beam is also provided with tongues that are received in glide slots having substantially vertical sidewalls so that the beam cannot pivot about its longitudinal axis or a substantially vertical axis. Preferaly the rider roll beam will be directly supported at each end by a hydraulic cylinder that raises and lowers each end of beam substantially independently of the other.

Abstract: A paper slitter machine having a plurality of slitter heads in mutually spaced apart relation located across the width of the machine, each slitter head having a slitter disc operable in cooperating relation with a respective annular disc or slitter band mounted for rotation on a shaft, for the slitting of a paper web into discrete width portions on passage of the web past the slitter heads, is provided with a plurality of slitter indexing means mounted on traverse means for retraction to a position clear of the machine, the slitter indexing means having a slitter stop for each slitter head, the stops being adjustable upon the traverse means to permit pre-indexing of each of the stops to a desired predetermined position along the length of the traverse means such that, with the traverse means repositioned within the slitter machine and having the stops positioned in an operative position, each of the slitter heads may then be brought rapidly into indexed relation with the respective pre-set stop, whereby the

Abstract: A reel bar guides for a paper reeling machine include a pair of track-mounted spaced apart carriages on which the reel bar end bearings are respectively mounted, and a looped cable system interconnecting each end of each carriage with the other carriage, including guide pulleys to maintain the cable runs in tensioned free-running relation, whereby displacement of one carriage in a first direction along its respective track produces simultaneous displacement of the other carriage in the same direction along the other track.
