9. If you find that a laminated layer has not welded together sufficiently to leave a clear edge for trimming, it is
usually possible to put the layer back in the next stack of laminations and go through the same procedure again,
with a slight increase in time in order to allow thorough lamination.
10. Remember that consistency and regularity in operation of this press will pay dividends in a minimum of
spoilage and "retakes".
11. In laminating, the thermoplastic material used is brought to a semi-liquid condition while between the heating
plates. After transfer to the cold opening of the press, it is most important that proper pressure be maintained
during the cooling cycle, for it is in the cooling cycle that the plastic sets or changes from a semi-liquid to a
solid state. The press is designed so that the cooling operation will be a little faster than the heating, therefore
maintaining a continuous flow of production.
12. Always keep in mind that a stack of laminations will require the same pressure for cooling as is required for
heating. You cannot cool a stack of laminations have 5" x 6" (12.7 x 15.3cm) sheets of plastic at the same time
you are heating a stack of laminations have 3" x 4", 4" x 5" (7.6 x 10.2, 10.2 x 12.7cm) or smaller sheets of
plastic. It will be readily seen that the two stacks will not have equal pressure per square inch applied to the
plastic.
13. Many of the thermoplastic materials on the market may be used with the CARVER Laminating Press such as
acetate, vinylite and certain acrylic materials. Pressures, temperatures and time for laminating the various
materials will however, be different.
