Abstract

Roll grooving apparatus for rolling a circumferential groove in a pipe is adapted to be mounted on a power drive unit for the axes of the driven and idler grooving rolls to lie in a plane which is one of horizontal or at an acute angle to horizontal such that the weight of a pipe between the grooving rolls during a roll grooving operation promotes tracking of the groove. A rotatable groove depth gauge is mounted on a support member of the apparatus adjacent a stop element which engages the support member to determine groove depth, and the gauge is displaceable relative to the stop element into and out of a gauging position in which the stop element can be set to control the groove depth in a given workpiece.
