Effects of Roller Deflection | |
|
Rollers in your machine should be designed with enough beam strength to avoid roller buckling (deflection). Roller face length and web tension (total "weight" supported by the roller) are to be considered to calculate potential roller deflection. Acceptable levels of deflection depend on the paper, film, foil, textile or nonwoven web and its reaction to the deflection. Additionally, your application and acceptable end product come into play. Deflection calculators found here may help to determine deflection levels for dual supported rollers and cantilevered rollers in a given application. Roller buckling will cause web wrinkles. Anti-wrinkle systems can help to eliminate wrinkles, prior to becoming creases.
