Abstract
A sheet combining device includes at least one former, at least one longitudinal cutter, and at least two partial web guide routes. A respective partial sheet of partial cut webs can be conveyed on each of the at least two partial web guide routes. These sheets can be combined to form a principal sheet at an exit of the sheet combining device. A stapler is provided on one of the at least two partial web guide routes and is used to staple the partial sheet which is conveyed on that guide route.
Claims18
A continuous web mixing device comprising:
- at least one first, upper former;
- at least one longitudinal cutter associated with said at least one first, upper former and adapted to cut a first continuous web, constituted of a first plurality of parallel webs and associated with said first former longitudinally, in a direction of travel of said first continuous web through the web mixing device, into at least first and second cut partial continuous webs each constituted of said plurality of parallel webs;
- at least first and second partial web guide paths associated with said at least one first, upper former, each of said at least first and second partial web guide paths being adapted to each conduct a respective one of said plurality of parallel webs of said first and second cut partial continuous webs from said at least one first, upper former;
- a second, lower former having first and second sides, said second, lower former being located after, in a direction of travel of the first continuous web, said at least one first, upper former, said second, lower former being adapted to guide a second continuous web, constituted of a second plurality of parallel webs, and being movable along a second continuous web guide path, said at least first and second cut partial webs, each associated with said at least one first, upper former, and each constituted of selected ones of said first plurality of parallel webs each being simultaneously conducted past one of said first and second sides of said second, lower former;
- a stapler in at least one of said at least first and second partial web guide paths associated with said at least one first, upper former and said second continuous web guide path associated with said second, lower former;
- and
- an outlet of said web mixing device located after said at least one first, upper former and said second, lower former, said at least first and second cut partial continuous webs, after each being conveyed past one of said first and second sides of said second, lower former, being united, at said outlet of said web mixing device, with said second continuous web constituted of said second plurality of parallel webs, and associated with said second, lower former, to form a main continuous web.

A method for mixing continuous webs including:
- providing at least one first, upper former;
- associating at least one longitudinal cutting device with said at least one first, upper former;
- conveying a first continuous web constituted of a first plurality of parallel webs through said at least one first, upper former and said associated longitudinal cutting device and forming at least first and second longitudinally cut and formed partial continuous webs each constituted of said first plurality of parallel webs;
- providing at least first and second spaced guide paths after said at least one first, upper former;
- providing a stapler in at least one of said first and second spaced guide paths;
- moving each one of said first and second longitudinally cut and formed partial continuous webs along a respective one of said first and second guide paths;
- stapling together said first plurality of parallel webs of at least one of said first and second longitudinally cut and formed partial continuous webs using said stapler;
- providing a second, lower former after, in a direction of web travel, said at least one first, upper former;
- locating said first and second guide paths on first and second spaced sides of said second, lower former and guiding said first and second longitudinally cut and formed partial continuous webs each on one of said first and second spaced sides of said second, lower former;
- conveying a second continuous web constituted of a second plurality of parallel webs through said second, lower former;
- providing an outlet;
- combining said first and second longitudinally cut and formed partial continuous webs and said second continuous web into a main continuous web at said outlet, said at least one of said first and second partial continuous webs being stapled together using said stapler before being again united with the other of said first and second longitudinally cut and formed partial continuous webs and said second continuous web into said main continuous web;
- providing a folding apparatus;
- and
- locating said folded apparatus after, in said direction of web travel, said outlet.
