Abstract:
1. A folder system for folding a continuous web of material, the system comprising: a spiral folder assembly having a first set of rotatable spirals and a second set of rotatable spirals; a deflection means that alternates between a first position and a second position, the deflection means configured to guide the continuous web toward the first set of spirals when in the first position and toward the second set of spirals when in the second position; a beater assembly having a first beater to urge the continuous web against the first set of spirals to form a first fold in the web, and a second beater to urge the continuous web against the second set of spirals to form a second fold in the web; a conveyor assembly configured to receive and transport the folded continuous web as it exits the spiral folder assembly, the conveyor assembly providing a support disposed between a first vertical plane defined by the first set of spirals and a second vertical plane defined by the second set of spirals, the support adapted to modulate an amount of sagging in the continuous web as the web is suspended between the first set of spirals and the second set of spirals; and a first and second stop bars located against the first and second sets of rotatable spirals respectively to restrain movement of the continuous web when the web is urged against the first and second sets of spirals by the first and second beaters respectively.
