Draw is the speed difference between sections, and on a tissue machine the crepe ratio between the Yankee and the reel shapes stretch, bulk and softness.
Enter the upstream and downstream speeds to get both, as percentages.
Machine
Speed difference (draw) between two sections, e.g. Yankee to reel for crepe.
e.g. Yankee
e.g. pope reel
Draw
-16.67%
Draw = (downstream − upstream) ÷ upstream. Crepe ratio = (Yankee − reel) ÷ reel.
Production rate
Tonnes per hour, day and shift from machine speed, grammage and trim width.
Reel length and weight
Paper length and weight on a reel from its diameter, core, width and caliper.
Consistency and dilution
Dry fibre flow, and the water needed to dilute stock to a target consistency.
Basis weight, bulk and density
Convert grammage to imperial basis weights, and work out bulk and density from caliper.
FibreMate logs reels and stops as the shift runs and works out production, OEE and lost time for you.
