ABSTRACT:
A folding machine having a horizontally elongated input plate with front and rear horizontal edges, a mechanism including input wheels disposed at the rear edge, the mechanism having a first position at which the wheels are disposed above the plate and a second position at which the wheels are lowered to said plate, a horizontally elongated roller rotatable about its own axis and disposed at the rear edge, the wheels being engaged with the roller when the mechanism is in the second position and a motor for rotating the roller. The machine also includes first and second spaced apart photoelectric circuits, each circuit producing a vertical light beam, which, when not interrupted, passes the rear edge, said beams defining a vertical plane, as well as a third photoelectric circuit producing a horizontal light beam which, when not interrupted, passes horizontally along the rear edge parallel to said plane. A first device connected between the first and second circuits and the mechanism is responsive to the interruption of both vertical beams when material to be folded is placed upon the plate in the path of both beams to place the mechanism in the second position, the mechanism being otherwise in the first position.
A second device coupled to the first device, the third circuit and the motor to actuate the motor and rotate the roller only when the mechanism is in the second position and the horizontal beam is not interrupted.
