Abstract:
1. A method of pre-adjusting a leg guide path in a forming device configuration of a web-processing machine including: providing a plurality of longitudinal fold forming devices in said forming device configuration; using said plurality of longitudinal fold forming devices for each forming a folded web strand printed by said web-processing machine; arranging first and second ones of said plurality of longitudinal fold forming devices on a first horizontal plane; arranging third and fourth ones of said plurality of longitudinal forming devices on a second horizontal plane different from said first horizontal plane; providing a folding apparatus after, in a direction of web travel, a last one of said plurality of longitudinal fold forming devices; providing a separate leg guide path of travel from each said longitudinal fold forming device to said folding apparatus; providing at least one positioning element in said forming device configuration in at least one of said separate leg guide paths of travel of at least one of said folded web strands intermediate at least one of said plurality of longitudinal forming devices and said folding apparatus; using said at least one positioning element for varying a longitudinal length of said at least one of said separate leg guide paths of travel of said at least one folded web strand; providing a setting value for said at least one positioning element for any given one of said separate leg guide paths of travel of one of said a folded web strands; obtaining said setting value for said at least one positioning element using design data obtained from a computer-aided design program; storing said setting value in a machine control unit; using said machine control unit containing said setting value for positioning said at least one positioning element for any given path of travel of one of said separate folded web strands in a production condition of said web-processing machine; determining a subsequent correction of said at least one positioning element during production of said web-processing machine; and using said subsequent correction in said control unit as a new setting value for said at least one positioning element for said at least one of said separate folded web strands.
