Abstract
A sideweld bag making machine utilizing a rotary transfer device and wicket conveyer is equipped with screw adjustable transfer wicket pins. The bases for the transfer wicket pins are mounted on a threaded rod having two sections of thread, each of opposite hand. Rotation of this threaded rod affects the separation of the wicket pins. Adjustment of vertical position is accomplished by means of two jacking screws or a screw adjustment in conjunction with a motion limiting rail element.
