Abstract
The tongue includes a shaft, the shaft being hollow. The shaft includes a first end and a second end, the first end defining a first opening with a first radius of curvature, and the second end defining a second opening with a second radius of curvature. The first radius of curvature is larger than the second radius of curvature. The shaft defines at least one injection port that traverses through an inner surface of the shaft. A first plate is connected to the shaft. The first plate includes an engaging structure configured to mount the tongue onto a lower plate and align the shaft with a groove defined by the lower plate. The rod forming apparatus includes the tongue. The method installs the tongue onto the rod forming apparatus.
