Patent number: 6402132Abstract: A method for folding demand printed webs into signatures for gathering by rotary gathering and binding machines, as well as the signatures produced thereby, are disclosed. The method involves the steps of digitally printing pages onto a moving web of material, creating a series of fan folds across the transverse axis of the web, severing the web after a desired number of fan folds have been created to form a separate log, and chop folding the resulting log zero one or more times to form a signature. The resulting signature includes a plurality of layers each having pages printed thereon in proper orientation and sequence and includes a sturdy closed backbone which enables the signature to be easily handled by conventional high-speed rotary gathering machines.Type: GrantFiled: August 21, 2000Date of Patent: June 11, 2002Assignee: R.

Patent number: 6341771Abstract: A method of converting at least one strip of flexible material 12 into at least one stack of folded members 46. The method includes the step of conveying a number of festoons 20 formed from a strip of flexible material 12. The method is characterized by the step of depositing the respective festoons 20 into a stack of folded members 46. In the preferred method, the step of depositing the respective festoons 20 into a stack of folded members 46 can be characterized further by the steps of: (i) laying an initial flap 36 of flexible material 12 on a stacking surface 24; (ii) creating a first folded member 44 by placing a first festoon 42 on the initial flap 36 of flexible material 12; and (iii) creating additional folded members by placing each festoon upon a preceding festoon.Type: GrantFiled: January 25, 2000Date of Patent: January 29, 2002Assignee: The Goodyear Tire & Rubber CompanyInventor: Peter Gerald Sasson, Jr.

Patent number: 6336307Abstract: A package of a strip of material has a plurality of parallel side by side stacks each containing a length of the strip which is folded back and forth such that each folded portion of the stack is folded relative to the next portion about a line transverse to the strip. Preferably, the side edges of the strip portions are aligned. The strip can be continuous through each stack and connected by a splice from the end of one stack to beginning of the next stack. To reduce the height of the stacks, the package is compressed and maintained in the compressed condition by, for example, an evacuated sealed bag. The strip of each stack is formed to have a varying width, for example to form diaper inserts when the strip is cut into individual strip elements. The length of each strip portion of the stack is arranged to equal a whole number of strip elements so that the cut lines can be arranged at the fold lines.Type: GrantFiled: August 9, 1999Date of Patent: January 8, 2002Assignee: EKI Holding CorporationInventor: Lawrence J.
