Follow board pattern

This type of pattern is adopted for those castings where there are some portions which are structurally weak and if not supported properly are likely to break under the force of ramming. Hence the bottom board is modified as a follow board to closely fit the contour of the weak pattern and thus support it during the ramming of the drag. During  the  preparation  of  the  cope,  no  follow  board  is  necessary  because  the  sand which is compacted in the drag will support the fragile pattern. An example is shown in Figure.
