5.
Place the clamp in position on the projecting side of the holding plates.
6.
Turn the adjusting screw about a half turn or so in a clockwise direction (to the right).
7.
Close the clamp by squeezing on the lever. The lever should snap up against the main body of the clamp,
grasping the stack firmly.
IMPORTANT DO NOT GRIP THE STACK TOO TIGHTLY WITH
THE HOLDING CLAMPS. Just a firm grip, enough to hold the stack closed and afford easy transferring is

all that is needed. Too much pressure on the holding clamps may spring the holding plates and produce
bubbles in the laminations.
Polished Plates:
Polished plates are supplied in sets of (24) pieces; enough to build three stacks of laminations, six layers each, using
seven plates per stack. The three extra plates are supplied as spares in case some become scratched or damaged. These
plates are made of chrome-plated steel and are highly polished. When using the polished plates, be sure to center them
on the holding plates.
Blotters:
A set of (50) blotters is provided. One or two blotters are generally used between the polished plates and the holding
plates (see Method of Assembling Laminations). They are not intended as padding. Their main purpose is to prevent
heat from entering the stack too rapidly and distribute the heat evenly throughout the stack. They also protect exposed
surfaces of the polished plates. It is not necessary to replace the blotters for each lamination, however, if they become
brittle and hard due to high heat, they should be replaced. These are special blotters made for this purpose and should
last a considerable amount of time.
Thermometers:
Each press is supplied with (2) dial-faced thermometers with Centigrade (C ) gradations. These should be inserted into
the holes in each heating plate. Care should be taken not to hit the lens of the thermometer or damage may occur.
Oil:
Each press is supplied with one pint (.47 liters) of Special Hydraulic Oil #2170, but this should only be needed if there
has been some visible loss. Keep this bottle sealed from dirt and dust. We advise using only CARVER Hydraulic Fluid
or those recommended as substitutes earlier in this manual.
Spare Seals:
Each press is supplied with a spare soft copper washer for use in the gauge connection. If one seal does not prevent oil
leakage, two seals may be used.
LAMINATION:
This CARVER Laminating Press is the finest equipment of its type available. Properly operated, it produces superior
laminations, which are not only pleasing in appearance and "feel" but are welded or fused together. Separation under
ordinary conditions is impossible. Cards or papers are essentially tamer-proof and are protected indefinitely. Please
take time to read and understand these instructions. A little practice is, of course, necessary, but you will be rewarded
with outstanding results.
METHOD OF ASSEMBLING LAMINATIONS:
If it does not, adjust the end screw until it performsas specified above.
