Method of and apparatus for producing stacks of folded sheet material
US 3845948 A
Abstract
Stacks of folded sheets with a C-fold, Z-fold, V-fold or other various kinds of folds are formed from a plurality of webs of flexible sheet material such as paper toweling or creped tissue. To form the stacks of folded sheets, the webs are longitudinally folded while traveling along a path to an accumulator at which the folded webs travel about a closed path a plurality of times and accumulate as a multiple series of webs stacked in an endless log. The endless log is severed at spaced intervals to form a plurality of individual stacks of folded sheets. When it is desired to interfold the sheets throughout the stack, the series of folded webs are first interfolded with each other while traveling to the accumulator whereat a portion of an outer one of the incoming series of webs is interleaved with a portion of an outer web of the partially formed log completing one revolution about the closed path on the accumulator.
