Abstract
Roll grooving apparatus for rolling a circumferential groove in a pipe comprises a first support rotatably supporting a first grooving roll, a second support rotatably supporting a second grooving roll and being displaceable relative to the first support for displacing the second grooving roll toward and away from said first grooving roll, a stabilizer on the first support for stabilizing a pipe to be roll grooved, and first and second guards pivotally mounted on the second support for displacement therewith. The first guard engages the stabilizer, the second guard engages a pipe being roll grooved during a roll grooving operation and each guard is spring biased to engage the corresponding one of the stabilizer and a pipe being roll grooved. A member on the first support engages and displaces the second guard away from a pipe which has been roll grooved when the second support is displaced to move the second grooving roll away from the first grooving rolls.
