A press head assembly for a concrete pipe making machine includes a head that is not released onto a concrete pipe form, but instead remains on the press head assembly after forming the spigot end of a concrete pipe. The machine further includes a linear actuating means, such as a pneumatic cylinder, for raising and lowering the press head assembly, including the head, between a raised position and a lowered position. In the lowered position, the head is positioned on the concrete pipe form,to form the spigot end of the concrete pipe. The press head assembly further includes angular actuating means, such as a hydraulic stepper motor, for rotating the head relative to the concrete pipe form. The head is simultaneously rotated and lifted off the concrete pipe form so that the spigot end of the concrete pipe has a smooth "troweled" finish.
