CREST™ 400 GlueUnitThe CREST 400 Double GlueUnit compact design meets maximum production speedsand is capable of running the full range of board grades and flute types.

Eccentric flanges, fitted on both sides the machine, provide parallel adjustment of the doctor roll to the applicator roll. The gap between the chromed doctor roll and the applicator roll is controlled to an accuracy of 0.118 in., achieved via a high precision servo gearbox. The Anilox glue applicator roll (11.81 in. diameter) has its own dedicated and independent drive.

The glue gap can be on either manually (the operator sets target gaps and the machine automatically maintains such a gap), or fully automatically (the gap is set according to the pre-configured glue curve), where a constant glue film thickness is ensured at all speeds.

The CREST™ is supplied with a contact bar or a rider roll system, according to customer requirements. The rider roll configuration is attached to an upper arm that pivots. This can be adjusted through a finite control altering the position through a zero backlash jackscrew. This design provides absolute gap accuracy and adjustment guaranteeing the starch is precisely applied to the flute tips only.

An adjustable width stainless steel glue pan is specifically designed to prevent glue slinging. Each operating level and its corresponding starch flow control are fully independent from the other level, allowing accurate glue film application at all speeds. Starch is fed into the center and drains out of the two sides of the pan.

The glue reservoir is automatically kept at constant levels. The glue film is generated below the actual glue level and is always under constant hydrostatic pressure, allowing accurate glue film application at any speed, in addition to reducing starch consumption. To facilitate cleaning, the entire glue pan can be tilted away.

The on-board drive panels and operator console is standard with touch screen control, providing visualization of data, machine settings, alarms, comprehensive machine diagnostics and manual over-ride.
