Introducing the Simon S-Press. It is the latest in Double-Backer heat transfer technology. The construction is simple. In the unloaded position, the pressure plates are raised from the board line and held there by the compression springs. In its loaded position, the air bad is inflated. The pressure inside the bag overcomes the compression springs and lowers the pressure plates to contact the belt.. This special loading mechanism enables the S-Press to achieve a “Kiss Touch.” The “Kiss Touch” provides sufficient pressure to create and extremely effective means of heat transfer to the corrugated board. The best part is the savings. Save over 50% on the price of a brand new Double Backer with the Simon rebuild. Looks as good as new.
