Chill rolls are designed to cool the web to a specific temperature before the winding process to achieve perfect end rolls. Chilled rolls are widely recommended to prevent hot adhesive from damaging the substrate, and to facilitate cutting and slotting processes after lamination. More specifically, chilled rolls are used on “against-roll” applications to ensure a consistent coat weight throughout the roll, avoiding the miss-adjustments caused by the dilation of non-chilled rolls. Alternatively, this type of rolls can also be “warm rolls”. This is used to laminate on substrates were you need to control the adhesive absorption and therefore, the substrate needs to be kept warm for a longer time.
