ABSTRACT:
A machine and method for making folded strips, which machine and method are characterized by features that enable a reduction in the size, weight and cost of the machine. The machine and method comprises a housing having first and second housing sections, a longitudinal severing assembly for longitudinally severing the sheet stock material into a plurality of strips, and a folding device downstream of the longitudinal severing assembly and operative to cause back and forth folding of the strips to produce accordion-folded strips having substantially uniform adjacent opposite folds. The longitudinal severing assembly includes first and second slitting members respectively carried in the first and second housing sections, and the first and second housing sections are separable whereby the housing is openable to maintain and repair the machine. The slitting members include a shaft and an array of slitting discs carried on the shaft for rotation therewith. The slitting discs are individually axially shiftable relative to the shaft and a biasing member is used to resiliently bias the slitting discs towards one another to hold the same assembled as a stacked array. Also provided are first and second arrays of combers passing through respective spaces between relatively adjacent cutting discs of the first and second slitting members, respectively. The first and second array of combers define therebetween a passageway which directs the sheet stock material between the first and second slitting members, and the combers each are in the form of an elongated member having an inner surface defining a part of one side of the passageway and an outer surface disposed inwardly of the rotation axis of the respective slitting member at the same side of said passageway as the comber.
