Abstract: At the filling station of a dry cast pipe making machine for making pipe lined with a plastic liner, the liner is first placed over the core and then a plurality of spaced-apart, removable L-shaped plates are secured around the top edge of the core. One leg of each plate extends inside the core with the other leg extending downwardly over the top edge of the liner. The plates are removably held in place on the core by the use of a clamping device, such as a vise-grip, for example. Once the form is filled with concrete and ready for the pressure heading step, the downwardly extending legs of the plates serve as ‘shoehorns’ to guide the pressure header over the top of the liner and prevent damage to it. In addition, the plates will assist in centering the core within the jacket.
