Nip roll machines with larger openings than 1 ½” are available in two models – the SP3, which can have up to a 3” opening between rolls, and the SPL, which is able to go to a 6” opening..
The SP3 has a floating upper pinch roll like the standard smoothing press. The upper roll is mounted to a set of extended arms which allow adjustment up to a 3” opening between rolls.

It can also be equipped with the air cylinder option (the ACP version), which can increase the squeeze pressure between rolls to as high as 600 lbs.
