Front Matter Safety Statements The SEAL 44 Ultra laminator has been designed with operator safety as a primary objective; however, operators must be familiar with the controls, as well as the operation before using the unit. The electrical and drive-system components are isolated from contact with the operator by enclosing them within plastic end covers that are bolted on. Only qualified service technicians should remove these protective covers after power to the machine is removed

Front Matter Note: When performing procedures that require the side covers to be opened, ensure that the power cable is disconnected from the mains. Several parts, like the fast-on connector strips of the overtemperature switch (white arrows in picture shown below), could cause electrical shock if the power is not disconnected! v

Machine Characteristics 1 Machine Characteristics 1-1 Machine Description The SEAL 44 Ultra laminator is an electro-mechanical device basically containing two siliconized laminating rollers, two siliconized pull rollers and a top and bottom film unwind. Only the top roller is heated. There are three temperature ranges; the speed can be set to any value between zero and maximum speed. There is a set of nip values to accommodate for the various panel thicknesses. The machine runs on

Transport & Installation 2 Transport & Installation 2-1 Transport Only use a pallet jack or forklift to lift and transport the machine. The machine is transported on a wooden pallet, which is an integral part of the packaging. The machine is wrapped in plastic film to avoid moisture penetration. 2-2 Workspace Requirements • This unit should be situated away from heat sources such as heat registers or stoves. • There should be enough space around the laminator to feed-

Theory of Operation 3 Theory of Operation 3-1 Control Knob The Control Knob (see figure 1) is located on the right hand side of the laminator and is operated from the front of the machine. The Control Knob can be operated by pushing it in approximately 6mm (1/4”) to the left. Once the knob has disengaged from the stop, it may be rotated forward or backward (clockwise or counter- clockwise, viewed from the right hand side of the unit). Continue to rotate the knob until the d

Theory of Operation 3-4 Motor Control The speed of the rollers is continuously adjustable between 0 and 1.5 m/min. (0 and 4.9 ft/min.) Pressing the key runs the rollers in forward direction, pressing the key reverses the direction of the rollers (as long as this button is pressed). The stop key stops the roller movement. Slow-mode The machine has a so-called slow-mode, which can be activated by pressing the foot switch. To maintain slow-mode, keep the foot switch presse

Theory of Operation 3-5 Unwind Brakes Tighten the unwind brake so that it applies sufficient tension to laminate. Turning the knurled collar in a clockwise direction increases the unwind tension applied to the laminate. Turning the collar counter- clockwise decreases the tension. The best setting for the brake tension is determined by the materials you are using and is learned through experience. Note: In general, no or light unwind tensions will be required. 16
