"Beehive" Forms Stacking
A stacking device is disclosed, in which weighted cords form an envelope
within which continuous forms are stacked at high speed, eliminating the usual
vertical steel forms.
The Figure shows that Cords 1 are suspended from the horizontal rods of the
Upper 2 and Lower 3 Wire Guides at the rear of a known printer. Each Cord
carries a Weight 4. Also hung from Wire Guides 2 and 3 are Chains 5. It is seen
that as Forms 6 enter the stacker from between the Wire Guides, the weight of
one of the Chains 5 will cause the Forms to start to re-crease. These "Worker"
chains swing to and fro causing the Forms web to re-crease first in one direction
and then the other. The Forms continue on a downward path guided by "Drone"
Cords 1, coming to rest in a horizontal position atop Shelf 7. As the forms Stack
8 builds up, it is confined by Cords 1, which, held in tension by Weights 4, form
the "Beehive" envelope.
In the present embodiment there are three Cords 1 and four Chains 5 hung
from each Wire Guide. The number of each required, and their spacing, will
depend on the specific printer, and the sizes of the various forms to be handled.
The Cords should be of a material such as nylon, that is wear resistant in paper
