  • Adjustable sheet guide assembly
    Patent number: 5259309
    Abstract: An adjustable sheet guide assembly utilizes a plurality of individually shiftable sheet guide elements. Each of these sheet guide elements is carried by a sleeve which is concentric about a hollow profile body that carries a rotatable, helically fluted shaft. Guide pins on the sleeves are received in the shaft's flutes so that rotation of the shaft or movement of one sheet guide element causes movement of all of the sheet guide elements in the adjustable sheet guide assembly.
