A pendulum type folder chute detachably mounted to spindles journalled in the side frame walls and having duplicate crank arrangements on either side thereof, including a crank arm, a link arm, and a drive wheel on either side frame such that the mass and driving force of the crank arrangement is balanced. The drive wheel includes a stroke adjustment feature which includes a circular recess defined in the outer surface of the drive wheel, the center of which is offset from the axis of rotation of the drive wheel, and a circular disc is provided in the circular recess rotatable therewithin and having its geometric center coinciding with the geometric center of the recess. A plurality of holes are in a circular locus in the recess coinciding with the locus of a plurality of holes provided on the disc near the periphery thereof. Bolt means pass through the holes in the disc to engage the holes in the recess to thereby lock the disc in a selected position. The second disc mounts a spindle which is offset from the geometric center thereof such that when the disc is rotatably adjusted and locked within the recess, the eccentricity of the spindle relative to the center of the first disc can be varied, and a linking arm is connected to the spindle such that the stroke of the chute can be adjusted by adjusting the relative position of the second disc to the wheel in the recess thereof.
