ABSTRACT:
Methods and devices for folding a continuous web of material are provided. Systems can include a spiral folder assembly having first and second sets of rotatable spirals, a deflection means to guide the continuous web toward the first set of spirals and the second set of spirals, a beater assembly to urge the continuous web against the first set of spirals to form a first fold in the web against the second set of spirals to form a second fold in the web, and a conveyor assembly to receive and transport the folded continuous web as it exits the spiral folder assembly, the conveyor assembly providing a support between the first and second sets of spirals, the support modulating an amount of sag in the continuous web as the web is suspended between the first and second sets of spirals.
