Forms Stacking Aid

The reliability of stacking continuous forms is improved by providing a deflector in the forms path approximately one-half to one-third the length of a form above the top of the stack.

Referring to the figures, a deflector 1 is positioned along the stacker wall 2 approximately one-third to one-half the length of a form 3 above the top 4 of the accumulated stack of forms. The deflector is preferably mounted on a movable support which can change the location of the selector as the top of the stack rises.

During stacking of an in-fold (Fig. 1), the paper is constrained by the fixed "pivot" 5 of the previous out-fold so that the in-fold is momentarily resting on the deflector and then follows the constrained path to the stack. For an out-fold (Fig.
2), the deflector causes the incoming form to roll outwardly onto the stack. The height at which the deflector is placed should be such that the distance from the outer edge of the stack to the deflector allows an in-fold to rest on the deflector when the previous out-fold comes to rest, and the distance from the inner edge of the stack to the deflector is approximately one-half form length or less. The deflector may be a plurality of aligned devices or a single device across the paper width, and may have various contours.
