Abstract
An automatic laminator for laminating film on a board includes a control unit, input and output roller tables, and a control cabinet. The control unit includes a tacking system, film supply rolls, takeup rolls, lamination rolls, a cutting system and a vacuum system. The control unit features holding the board stationary between the completion of the tacking operation and the beginning of the lamination operation and the starting the lamination at substantially the same position where the tacking has been effected, thus improving the efficiency of operation and enabling a reduction in the time, pressure, and temperature required for the successful performance of tacking. This together with a simple and effective cutting system involving a cutting blade that moves only a few millimeters and cuts the film 'on the fly' enables an increase in the rate at which the boards may be laminated. Single side lamination of very thin boards is also made possible. The input and output roller tables, the lamination rolls and all the machines are adjustable in height. The input table is fitted with a centering device and with a gripping system for feeding the panels to the lamination rolls. The output table carries a temperature sensor to measure the temperature of the panels and photocells to detect jamming of the boards. The control cabinet houses an electronic control and video display unit with keyboard.
