How often should Thermo Bar^® springs be changed?
Every three to four years. The springs in the Thermo Bars^® will also relax and lose free length, as most springs do. This is especially important for plants that run E or F flutes.

How often should Finger Holder springs be changed?
Every six months. This will keep the fingers from moving too freely away from the corrugating roll.

What air pressure setting should I use for the Thermo Bar^® system?
80 PSI. This will provide adequate pressure to lift the bars off of the belt when needed.

What should my gap setting be on the Contact Bar^®?
The gap setting should be .030" - .060" from the underside of the shoes to glue roll depending on the smallest flute height run. Be sure to use a flexible feeler gauge such as Mylar die backing. A rigid feeler will not conform to the curvature of the shoe and glue roll.

At what height should I set my Thermo Bars^®?
The height setting for Thermo Bars^® is 3" from the top of the shoe to the underside of the main tube. Traction Bars^® are 2 3/4". The bars must be in the down/run position (no board in machine) in order to accurately measure.

At what speed should I set my glue roll on my Glue Machine?
It's recommended that the glue applicator roll speed for the double backer be set at 98% of paper speed.

What's the difference between the FI Black Brake Pad and the K-Green Brake Pad?
The black pad is our standard pad; the green pad is our extended life pad and is made of a kevlar material. In fact, the K-Green pads offer three times the life of the black (standard) pad. Contact us for specific pricing information.
