When a reel comes off the machine, its weight decides production figures and its length decides how many rolls it will convert into. This calculator works out both from measurements you can take on the floor.
Use the wound caliper: tissue in particular is bulky, so a measured value gives a far better answer than a nominal one.
Production
Paper length and weight on a reel from its diameter, core, width and caliper.
Wound caliper; tissue is bulky, so use the measured value
Reel weight
1.77t
Length = π × (D² − d²) ÷ (4 × caliper); weight = length × width × grammage.
Production rate
Tonnes per hour, day and shift from machine speed, grammage and trim width.
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.
OEE from shift numbers
Availability, performance, quality and OEE from the figures on a shift report.
FibreMate logs reels and stops as the shift runs and works out production, OEE and lost time for you.
