Deighton FORMATIC Instruction Manual page 12

Generally the size of the paddles should balance with the size of the product being formed i.e.,
small paddle combination for a small product.
Deighton Manufacturing will supply the machine with a series of paddles suitable for the mix
being used and the form sizes being created however you can obtain various sizes and
combinations if problems occur with those supplied
With each mix you use for the first time start it with the smallest bottom paddle available with no
top paddle (In this case a top paddle spacer will have been supplied if deemed appropriate). If the
form will not fill, fit the smallest top paddle and if problems still occur continue to fit a larger
bottom then top paddle until the form is filled.
