Abstract: A pleat forming apparatus is formed with a "U" shaped framework including a plurality of rotatably mounted threaded rods therethrough. The threaded rods are mounted rotatably through forwardly extending legs of the "U" shaped frame wherein the threaded rods are mounted from opposite directions through the legs of the framework and through pleat arm supports mounting the pleat arms of the instant invention. The pleat arms include telescoping arms thereover for dimensionally lengthening the effective span of the pleat arms. The threaded rods are rotatably mounted to vary the spacing of the pleat arms to accommodate various material to be pleated and effect a desired pleat spacing.
