Abstract
This is an invention concerning an improvement of the clamp equipped in the cutting machine (guillotine) for cutting a pile of paper or similar materials. This invention consists in construction of the clamp in which the presser foot having clamping surfaces to press the cutting material and gauge surfaces facing the knife is composed of an alignment of many partial presser feet, each of which can individually be displaced according to the reaction force generated in pressing the cutting material. Even in case there is uneven thickness of cutting material or partial variation in compressibility, uniform clamping is obtained and brings about the good effect that the guillotine cutting is smoothly and exactly achieved.
