A laminating machine has first and second parallel horizontally oriented heated rolls, the first roll positioned below the second roll, and the second roll movable vertically relative to the first roll. There is also provided a pair of pull rollers positioned at the back of the machine for drawing laminating material through the machine. A substantially hollow horizontal work table having a plurality of perforations in the top thereof and a fan at the bottom thereof is positioned at the front of the machine. The fan draws air through the perforations in the top of the table to create a vacuum and retain material against the table as it is fed into the machine. The second work table is positioned at the back of the machine adjacent the pull rollers. The machine further has dual controls such that it may be operated from the front or the back thereof, and a plurality of turn off switches such that the heating elements and motor may be turned off, and the first and second rollers separated upon contact with any one of the switches.
