It is clearly a Switch Mode Power Supply (SMPS) for a motor and a heater. Laminating machine? There are a few nice components on the board: Two extremely high resistance resistors in glass encapsulation. They are marked 302M, that could be 3000 Mohm = 3 Gohm. There are also two 600 V 5 A Triacs, a bi-directional SCR. Some voltage transient absorbers and three opto-couplers, four good fuses and some various TTL.
