Abstract
Abstract The invention disclosed herein relates to a unique method for folding sheet material for serial extraction from packaged dispensers involving longitudinal folding and a series of transverse folds of superimposed sheets of paper, cloth or other flexible material. Packaged dispensers of various shapes and containing supplies of such folded products for serial extraction thereof through apertures of varying geometrical configuration are provided. An additional embodiment involves a continuous process for folding and rolling sheet material into generally cylindrically-shaped association for packaging and dispensing.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
119 words
A method for associating paper stock sheet material into packageable arrangements for serial disengagement which comprises: a. loading a plurality of individual sheets of said material successively onto a pair of horizontally disposed conveyor belts moving in parallel relationship in the same direction at the same rate of speed with said sheets placed on substantially equal portions of said belts and the leading half of each successive sheet placed on the trailing half of the preceding sheet; b. causing said pair of belts to fold up to a vertical position in face-to-face relationship with said sheets folded between them, and thereafter c. folding said sheets in zig-zag fashion transversely as they move forward out of contact with said belts.
Claim 2
Independent Claim
119 words
A method for associating paper stock sheet material into packageable arrangements for serial disengagement which comprises: a. loading a plurality of individual sheets of said material successively onto a pair of horizontally disposed conveyor belts moving in parallel relationship in the same direction at the same rate of speed with said sheets placed on substantially equal portions of said belts and the leading half of each successive sheet placed on the trailing half of the preceding sheet; b. causing said pair of belts to fold up to a vertical position in face-to-face relationship with said sheets folded between them, and thereafter c. folding said sheets in zig-zag fashion transversely as they move forward out of contact with said belts.
Claim 3
Dependent Claim
18 words
Method according to claim 1 including creasing said sheets prior to the fold up movement of the belts.
Claim 4
Dependent Claim
51 words
Method according to claim 2 wherein after said belts are folded to a vertical position with said sheets folded therebetween, said belts continue through a turn-down direction from a vertical to a horizontal orientation after which said sheets are folded transversely as they move forward out of contact with said belts.
Claim 5
Independent Claim
155 words
A method for associating sheet material into packageable arrangements which comprises: a. loading a plurality of individual sheets of said material successively onto a first moving conveyor belt with the leading half of each successive sheet placed on the trailing half of the preceding sheet; b. passing said belt loaded with said sheets under a pair of conveyor belts moving in the same direction at the same rate of speed as said first belt; c. causing said belts to turn-over so that said first belt is situated above said pair of belts upon which said sheets now ride; d. removing the leading portion of said first belt from contact with said sheets after which said pair of belts are folded up to a vertical position in face-to-face relationship with said sheets folded therebetween, and thereafter e. folding said sheets in zig-zag fashion transversely as they move forward out of contact with said pair of belts.
Claim 6
Independent Claim
155 words
A method for associating sheet material into packageable arrangements which comprises: a. loading a plurality of individual sheets of said material successively onto a first moving conveyor belt with the leading half of each successive sheet placed on the trailing half of the preceding sheet; b. passing said belt loaded with said sheets under a pair of conveyor belts moving in the same direction at the same rate of speed as said first belt; c. causing said belts to turn-over so that said first belt is situated above said pair of belts upon which said sheets now ride; d. removing the leading portion of said first belt from contact with said sheets after which said pair of belts are folded up to a vertical position in face-to-face relationship with said sheets folded therebetween, and thereafter e. folding said sheets in zig-zag fashion transversely as they move forward out of contact with said pair of belts.
Claim 7
Dependent Claim
58 words
Method according to claim 4 wherein said pair of belts loaded with said sheets are passed under housing means at a location proximate to where the leading portion of said first belt is removed from contact with said sheets and whereby said sheets are creased along the center line prior to the fold up movement of the belts.
Claim 8
Dependent Claim
51 words
Method according to claim 5 wherein after said belts are folded to a vertical position with said sheets folded therebetween, said belts continue through a turn-down direction from a vertical to a horizontal orientation after which said sheets are folded transversely as they move forward out of contact with said belts.
Claim 9
Independent Claim
119 words
A method for associating paper stock sheet material into packageable arrangements for serial disengagement which comprises: a. loading a plurality of individual sheets of said material successively onto a pair of horizontally disposed conveyor belts moving in parallel relationship in the same direction at the same rate of speed with said sheets placed on substantially equal portions of said belts and the leading half of each successive sheet placed on the trailing half of the preceding sheet: b. causing said pair of belts to fold up to a vertical position in face-to-face relationship with said sheets folded between them, and thereafter c. rolling said folded sheets about an axis as they move forward out of contact with said belts.
Claim 10
Independent Claim
119 words

Claim 11
Dependent Claim
19 words
Method according to claim 7 wherein said sheets are creased prior to the fold up movement of the belts.
Claim 12
Dependent Claim
53 words
MeThod according to claim 8 wherein after said belts are folded to a vertical position with said sheets folded therebetween, said belts continue through a turn-down direction from a vertical to a horizontal orientation after which said sheets are rolled about an axis as they move forward out of contact with said belts.
Claim 13
Independent Claim
155 words
A method for associating sheet material into packageable arrangements which comprises: a. loading a plurality of individual sheets of said material successively onto a first moving conveyor belt with the leading half of each successive sheet placed on the trailing half of the preceding sheet; b. passing said belt loaded with said sheets under a pair of conveyor belts moving in the same direction at the same rate of speed as said first belt; c. causing said belts to turn-over so that said first belt is situated above said pair of belts upon which said sheets now ride; d. removing the leading portion of said first belt from contact with said sheets after which said pair of belts are folded up to a vertical position in face-to-face relationship with said sheets folded therebetween, and thereafter e. rolling said folded sheets about an axis as they move forward out of contact with said pair of belts.
