Abstract
Abstract An analog computer for simultaneously solving for unknown pleat dimensions and positioning movable forming mechanisms in a location representative of said dimensions. The computer includes left and right arms which are pivoted along the lower end of a mounting board and are secured at their free ends to longitudinally movable indicators disposed in left and right longitudinal slots formed along the upper portion of the board. The left slot is associated with a fixed scale formed on the board and the right slot is associated with a movable scale which is adjustable longitudinally through the board. A pin and slot connection between the arms and indicators moves the indicators through their respective slots as the arms are rotated. A fixed, center scale extends laterally between the top and bottom of the board and carries markings identifying individual grooves which form left and right sets of grooves extending longitudinally to the right and left of the center scale. Left and right forming components are removably positioned in each set of grooves astride respective arms and each component includes a longitudinally movable forming slide which movably engages the associated pivoted arm through the pin and slot connection. By placing guides in the forming components in selected grooves, adjusting the right horizontal scale, and rotating the arms to move the left and right indicators to positions corresponding to known input values, the forming slides are automatically positioned to provide unknown pleat dimensions. The forming components are then removed from the board and coupled together with the rods extending from the components providing physical structures for holding and marking the material to be pleated.
