A notcher for forming a notch on a photographic film or the like which comprises:

• (a) a cylindrical die having a die bore connected to a suction device;
• (b) a cylindrical notching cutter movable between and second positions, said notching cutter performing a cutting operation between said first and second positions, and said notching cutter being formed with an air hold which is communicated with said die bore when said notching cutter is in said second position;
• (c) a conveyor table supporting said die and having a guide groove by which said film or the like is guided to a notching position;
• and
• (d) means for driving said notching cutter between said first and second positions.

A notcher of a drawn-type for forming a notch on a photographic film or the like which comprises:

• a cylindrical die having a die bore connected to a suction device;
• and
• a cylindrical nothcing cutter movable between first and secdnd positions, said notching cutter having a cutting edge constituted such that a cutting operation is performed between said first and second positions when said nothching cutter is drawn, and said nothcing cutter being formed with an air hole communicating a portion of the nothcing edge with ambient air, the air being communicated with said die bore when said notching cutter is in said second position.
• whereby a notching chip is smoothly suched into sAid suction device and simultaneously therewith said nothcing cutter is effectively cooled from the inside of said notching cutter through said air hole.
