ABSTRACT:
Apparatus for the high speed automatic cutting of measured lengths of a multiplicity of materials in which the material is guidingly fed from a supply source centrally of a feed path by a pair of adjustable feed rollers driven by a stepping motor that measures the length of material to be cut in terms of the cumulative steps of the stepping motor, and in which a reciprocable cutter knife is actuated in each cutting operation by a controlled single revolution of a connected drive shaft. A presser member supported for movement with the cutter knife engages the material in advance of the cutting blade and holds the material during cutting. The feed rollers are adjustable to a preset operative position and are spring urged to this position, but are arranged for independent manual movement to a wider separation of the rollers than in the preset position. The urging spring is also adjustable to vary its effective urging force. A unique gear train drivingly interconnects the rollers and is arranged to maintain their teeth in meshed driving relation during and at the adjusted positions of the spaced rollers.
