LAMINATOR FOR AUTOMATICALLY REVERSING

摘要

PURPOSE: A laminator for automatically reversing a roller is provided to prevent failure of coating by automatically discharging with detecting rolling of coating film on the coating roller, and to improve working efficiency by not disassembling the heater assembly for removing the coating film. CONSTITUTION: An automatic reverse laminator coats by inserting sheets between coating films and heating and compressing through a roller(16). The laminator has a coating film rolling detecting unit(30) detecting rolling of the coating film on the surface of the roller, and a roller reversing unit discharging the rolled coating film by reversing the roller. A sensing pin is contacted to the circumference by increasing the diameter of the roller in rolling the coating film on the roller, and the motor is reversed by contacting switch terminals(33a,33b). Failure of coating is prevented by discharging and reversing the roller with detecting rolling of the coating film on the roller.
