Abstract
This is concern with design and fabrication of a powered paper perforating machine with efficiency and less cost for bindery department in printing industries. It is a machine that will compete favorably with the manually operated ones and reduce human efforts with minimum time consumption. It perforates up to 15 sheets of paper at each stroke and is powered by a horse power electric motor whose rotational motion is converted to a reciprocating motion in the perforation pin by the principle of eccentricity.
