    Abstract: A device for preparing pipe segments for joining with mechanical pipe fittings in a piping network is disclosed. The device has a fixed support with support surfaces engageable with the pipe segment, and a movable support facing the fixed support, on which to ols (54), such as grooving rolls (24), chamfering rolls (44), marking rolls (36) and cutting blades (50) are rotatably mounted. T he tools engage the outer surface of the pipe to form a circumferential groove, a marking pattern, a chamfer or a cut through the pipe when the movable support is moved toward the fixed support. A collar or cup having a circumferential side wall sized to receive the pipe is mounted on the fixed support adjacent to the support surfaces and radially reinforces the pipe to prevent it from collapsing or going out of round during groove formation.
