A pleating machine ( 20 ) is provided which allows extremely rapid, uniform pleating of flexible, tubular bodies ( 28 ), thereby eliminating the arduous and time-consuming task of manual pleating. The machine ( 20 ) includes an upper, stationary, female tubular jaw ( 90 ) and a lower, reciprocal, male tubular pleating jaw ( 92 ) which are oriented in superposed, substantially axial alignment, along with a drive assembly ( 26 ) serving to vertically reciprocate lower jaw ( 92 ). An elongated rod-type body support ( 24 ) extends downwardly through the upper jaw ( 90 ) and presents a pleating surface ( 88 a), so that upon reciprocation of lower jaw ( 92 ), the jaw lugs ( 105 ) successively engage the body ( 28 ) to form pleats ( 162, 164 ). The pleats ( 162, 164 ) are retained by keeper structure including inwardly extending female jaw segments ( 98 ) and weighted slide ( 89 ) mounted on support ( 24 ).
