Roller Press

This plc controlled machine is designed to press pre-assembled units with poly-iso-butylene (PIB) applied to the spacer bar, producing a primary sealed unit ready for gas filling and a finish seal. The machine is also used to press structural foam spacer bars like ‘Superspacer’. The press can be an integral part of a semi automatic line or as a standalone unit on the end of an existing glass washer unit.
