  • Patent number: 4257295
    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.

  • Patent number: 4034636
    Abstract: A lay table is placed adjacent to a cutting table with the tables in end-to-end relationship so that layups of limp sheet material may be prepared on the lay table and then be moved onto the cutting table for a cutting operation. A sled formed by a low friction, non-stretching, sheet material is first placed on the lay table and the layup is then formed on top of the sled. Motor-driven cabling extends between the cutting table and the lay table and when a layup is to be moved, the sled is coupled to the cabling and pulled by the cabling with a layup thereon onto the cutting table. The layup on the cutting table is then clamped in position, and the cabling pulls the sled out from between the layup and the cutting table.
