1. A device for laterally separating a plurality of traveling partial webs which have been slit longitudinally in a web of material, such as paper, to be wound into corresponding web rolls on a winding apparatus, the device having two rolls which are disposed to rotate substantially parallel with one another, the rolls each having a cylindrical surface bowed to form a crown having a crown vector, the crown vectors of the two rolls extending in substantially parallel planes, but extending in opposed directions, such that the partial webs are separated laterally a predetermined distance from one another when the partial webs pass over the bowed surface on one, upstream roll and such distance is maintained when the partial webs pass under the bowed surface of the other, downstream roll, comprising, in combination.a stand;

  • a support frame pivotally mounted about an axis in the stand so as to be capable of rotating about the axis parallel to the plane of the traveling web and to be fixed at a predetermined angular position, as desired;

    the rolls rotatably mounted in the support frame in spaced, parallel adjacency each roll mounted on one side of the pivot of the support frame;

    roll controlling means operatively associated with each roll, the support frame and the stand, the roll controlling means including a first roll turning means mounted on each roll for positioning each roll to selectively position the roll crown vector, the roll controlling means further including a second roll turning means fixedly mounted to the stand relative to the support frame in operative association with the first roll turning means;

    the first roll turning means comprises an adjustment lever attached to each roll for angularly turning the corresponding roll about the axis of rotation of the roll;

    the second roll turning means includes a stand lever fixedly mounted to the stand about the pivotable axis of the support frame;

    the roll controlling means further includes an extendable pressure/slide rod having one end attached to the adjustment lever and the other end attached to the stand lever for each roll;

    whereby turning movement of the support frame about the support frame pivot axis causes the extendable pressure/slide rods to move the adjustment lever of each roll to cause the crown vectors of the rolls to turn substantially equally about the axes of roll rotation in a direction opposite to the direction of support frame pivotal movement while remaining parallel to one another at desired crown vector locations.
