1-2 FEATURES & BENEFITS
Your new laminator has several standard features that set it apart from other models.
• Variable speed The laminator operates at any speed up to 15 feet per minute. Thicker films are
generally applied better at mid-range to lower speeds, while 1.5 mil film should be applied at mid-
range to higher speeds.
• LCD temperature display makes it easy to set and maintain the correct temperature. The
indicator light inside the heat switch comes on as the machine warms up. At set temperature the
indicator light turns off.
• Simple controls Conveniently placed switches provide a compact, reliable control pad. Icons and
international symbols are used for controls and safety warnings.
• Easy threading Threading can be the most difficult aspect of using a laminator, so the Professor
27 has built in threading aids. Once the upper and lower webs of film have been threaded through
the machine, bottom idler threading is automatic when the operator closes the feed tray into it’s
operating position.
• Forced air-cooling This allows laminating with thicker films. Without a cooling system, thicker
films will warp or ripple because they are still too hot when they come out the back of the
laminator. The Professor 27 has a more effective cooling system than any other machine in its
class and should be turned off after completing each laminating run ( group of items being
laminated ) to prevent excessive cooling of the heat rollers.
• Ease of cleaning The silicone rubber rollers of the laminator should be cleaned regularly.
• Attached safety shield/safety switch The polycarbonate shield is clear so operators can see their
work. It’s fixed to the machine and configured with an integral safety switch so the laminator will
not operate unless it is in the down and locked position .
• Lamination pressure The rubber rollers are spring-loaded and preset to ensure correct and even
lamination pressure.
• Supply roll tension controls Supply roll tension is easy to adjust by simply tightening or
loosening the tension control knobs on the supply roll mandrels.
• Ease of maintenance The Professor 27 is made to last. However, some items on a laminator do
wear out. Even the high-quality silicone rubber used in the rollers will lose flexibility over time.
Extensive use may wear out the rollers, or an operator may cut a roller by accident
• Reverse can be invaluable at times to help avoid problems or clear misfeeds.
• Silicone rubber laminating rollers are flexible enough to provide a good edge seal and firm
enough to offer a good surface seal. A high silicone content insures a much longer average roller
life.
• Removable power cord prevents unauthorized usage without locking away the whole machine.
• 100% Made in the U.S.A
