Abstract
A method for manufacturing paper having colored stripes, the method comprising the steps of feeding a slurry to a distributor and delivering the slurry from the distributor to a headbox through a plurality of delivery lines. The delivery lines are coupled to the headbox at a plurality of locations spaced across the headbox in a crossmachine direction. The method further comprises the steps of selectively introducing a first coloring agent in at least two of the delivery lines to selectively color the slurry passing through the at least two delivery lines and depositing the slurry received by the headbox on a papermaking wire to form striped paper.

A method for manufacturing paper having colored stripes comprising the steps of:
- feeding a slurry to a distributor;
- delivering said slurry from said distributor to a headbox through a plurality of delivery lines, said delivery lines being coupled to said headbox at a plurality of locations spaced across said headbox in a crossmachine direction;
- selectively introducing a first coloring agent in at least two of said delivery lines at said distributor to selectively color the slurry passing through said at least two delivery lines;
- and
- depositing said slurry received by said headbox on a papermaking wire to form striped paper.
A method for manufacturing striped paper comprising the steps of:
- feeding a slurry to a distributor;
- delivering said slurry from said distributor to a headbox through a plurality of delivery lines, said delivery lines being coupled to said headbox at a plurality of locations spaced across said headbox in a crossmachine direction;
- selectively introducing a first coloring agent in said distributor and into a first of said delivery lines to selectively color the slurry passing through said first delivery line;
- selectively introducing a second coloring agent in said distributor and into a second of said delivery lines to selectively color the slurry passing through said second delivery line;
- and
- depositing said slurry received by said headbox on a papermaking wire to form striped paper.
A method for manufacturing paper having colored stripes comprising the steps of:
- feeding a slurry to a distributor;
- delivering said slurry from said distributor to a headbox through a plurality of delivery lines, said delivery lines being coupled to said headbox at a plurality of locations spaced across said headbox in a crossmachine direction;
- providing a plurality of dilution water lines, each dilution water line being coupled to said distributor and in fluid communication with an associated delivery line;
- selectively introducing a coloring agent at least one of said dilution water lines to color the slurry in at least two of said delivery lines;
- and
- depositing said slurry received by said headbox on a papermaking wire to form striped paper.
