Abstract
PURPOSE: To secure a light punching of the hole free from any nap, by arranging the higher sides of the cutting blades of the punch toward the row of the punch holes.
CONSTITUTION: The higher sides of the cutting blades 1a of the punch pins 1 are arranged toward the row of the holes 2a of the punch plates 2. In case the paper tape is pulled out in such structure, the blade 1a touching first the paper tape touches at its higher side to produce a large clearance. As a result, no nap is produced. And in the moment of the final cut, the lower side of the blade 1a corresponds to the shorter side of the oval to reduce the clearance. Thus no nap is caused neither. In such way, a hole free from any nap can be punched light.
