ABSTRACT:
BACKGROUND
The present invention relates to a tamping mechanism and more particularly to an improved tamping mechanism for tamping the edges of a stack of sheets.
In present high-speed printing and paper assembling mechanisms, sheets of paper are fed at high speeds to an accumulating area where they are placed one on top of the other to form a stack. When the stack is complete (i.e. a predetermined number of sheets are accumulated) the stack is moved to other stations which perform other functions on the stack. It is important that the edges of the stack of sheets be straight and in alignment with each other so that when the stack of sheets move to another station, there will be no sheet with its edge protruding outside the edge of the stack. Hence, it is important to tamp the sheets edgewise on both edges after they are deposited on a stack. This will straighten out all the edges of a stack and move them into alignment with each other.
OBJECTS
The present invention is an improvement over existing tamping mechanisms and has for one of its objects the provision of an improved tamping mechanism in which the edges of the stack are tamped after each sheet is laid on top of the stack.
Another object of the present invention is the provision of an improved tamping mechanism in which simple means are provided for tamping the edges of the stack and straightening out the edges.
Another object of the present invention is the provision of an improved tamping mechanism which can operate at the speeds necessary for present high-speed printing and assembling mechanisms.
Other and further objects will be obvious upon the understanding of the illustrative embodiment about to be described, or which will be indicated in the appended claims, and various advantages not referred to herein, will occur to one skilled in the art upon employment of the invention in practice.
