ABSTRACT:
An improved pleating machine and method for creating a variety of pleated patterns that are not limited to repeating variation. Pairs of pleating blades move forward and rearward in a pleating motion. During the forward pleating motion, the pleating blades advance the material and create folds therein. The pleating blades then force the folds against heated cylinders resulting in pressed pleats in the material. Displacement of the pleating blades prior to the forward pleating motion causes a reverse pleat in the material; lack of such displacement causes a forward pleat. A cross-member moves to an engagement position and back to a resting position prior to each forward pleating motion. Switching devices, such as sliding blocks, slotted cams, or switch pins, attached to the cross-member selectively engage push-up rods which, in turn, selectively displace the coinciding pleating blades. The switching devices are electronically controlled to alternate positions. The method includes functionally applying the above-described pleating machine.
