Challenges in Winding Flexible Packaging Film

the winding tension is tapered smoothly as the roll diameter increases. The tension taper should be between 0 and 50%. A tension taper of 25% at full roll is common. Tapered tension reduces ‘end crowning’, ‘buckling’, ‘starring’ and ‘dishing’ roll defects in rolls of flexible packaging film material. Strain Curves for Various

Roll hardness tester - Wikipedia

Roll hardness is one of the most important parameters when deciding whether a roll is good or bad. A roll that is wound too softly can go out of round when handled. A roll that is wound too hard, on the other hand, can crack during transportation. These variations are difficult to detect. Above all, it is typically the variation in

Rolling (metaling) - Wikipedia

In metaling, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough.Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is

THE MECHANICS OF TENSION CONTROL

forces by actually decreasing web tension as the roll builds. The amount of taper tension is normally measured in percentage of set tension. For example, using the same 3.5 inch core diameter and 35 inch outside roll diameter, if taper tension was set to 50%, the tension will be linearly decreased from 3.5 inch core to 35 inch roll diameter so the
