Abstract: A material pleater embodying a plurality of parallel, longitudinally extending plate-like members carried by an elongated member with adjacent plate-like members spaced from each other to receive a pleat of material therebetween. An elongated pleat depresser has longitudinally extending, spaced apart depresser elements with each being disposed to move between adjacent plate-like members and depress a pleat of material therebetween. Detachable means connects the pleats thus formed to each other whereby they remain in the formed position after removal of the plate-like members and the pleat depresser.
