Abstract
The apparatus comprises a frame having a die pivotally connected to it at one end and anchorage means pivotally connected to it at the other end. The anchorage means carries a first roller. A second roller is adjustable transverse to the frame. A pipe pusher is integral with the die. The frame has adjustable legs to set the angle of the fame. A plastic pipe is pulled through the die and through the host pipe and is bent between the first roller, the second roller and the die. The frame fully contains the reactions arising owing to the bending of the pipe.
