Abstract

A device for covering a pipe (4) with a plastic sheath (1) is proposed, a pulling-in mandrel (7) being provided which is moved in the direction of the arrow F, bulging the sheath (1) at its end section and pulling it into the interior of the pipe (4) until it bears against the inner side of the latter, protuberances in the sheath caused by clamping devices (5) being prevented.
