Abstract: A method for bonding the tail of a convolutely wound log to the body is provided. The method comprises the use of a nonadhesive phase-change material to mechanically bond the tail to the wound log. The nonadhesive phase-change material is heated to an amorphous state prior to its application. Once applied to the wound log, the nonadhesive phase-change material mechanical bonds with the tail and wound log and as heat is lost, changes to a non-amorphous state. The mechanical bond can be selectively reversed through the application of a strength degradation accelerator.

Abstract: A system for printing 7 or more inks on a substrate is disclosed. The system can include: 6 or less rotating rolls disposed in operative relationship with a substrate, wherein each of the rotating rolls can comprise a vascular network configured for transporting at least one of the 7 or more inks in a predetermined path from an interior region to an exterior surface of the rotating roll. The vascular network can have at least one main artery, at least one capillary and a plurality of fluid exits on the exterior surface. At least one capillary is attached to a main artery and is in fluid communication with at least two fluid exits through a substantially radial fluid path to form a tree.

Abstract: A rotating roll for depositing a fluid on a substrate is disclosed. The rotating roll can have a central longitudinal axis, wherein the rotating roll rotates about the central longitudinal axis. The rotating roll can have an exterior surface defining an interior region and a vascular network configured for transporting the fluid in predetermined paths from an interior region to the exterior surface of the rotating roll. The vascular network can have a main artery, a first capillary and a plurality of fluid exits on the exterior surface. The main artery can have an inlet and is substantially parallel to the central longitudinal axis of the rotating roll. Fluid enters the vascular network at the inlet and exits through substantially radial fluid paths to form a first tree.

Abstract: A method for printing 7 or more inks on a substrate. The method can include the steps of: providing a substrate; providing 7 or more inks; and providing a print system, the print system comprising 6 or less rotating rolls. Each of the 6 or less rotating rolls can be disposed in an operative relationship to transport at least one of the 7 or more inks to a vascular network in one of 6 or less rotating rolls.

Abstract: A method of depositing a fluid onto a substrate is disclosed. The method can include the steps of providing a substrate, a fluid; a sleeve and roll system comprising a sleeve having a sleeve exit and an inner region and a rotating roll disposed within the inner region and a vascular network to supply the fluid from the interior region of the rotating roll to the exterior surface of the rotating roll in a predetermined path. The vascular network comprises a main artery, a tree comprising a first capillary, and a fluid exit on the exterior surface. The method includes the steps of transporting the fluid to the vascular network; controlling the flow of the fluid to move the fluid at a predetermined flow rate to the fluid exit; and contacting the substrate with the fluid.

Abstract: A system for depositing a fluid on a substrate is disclosed. The system can include a sleeve having a sleeve exit and an inner region and a rotating roll disposed within the inner region. A vascular network can be disposed within the rotating roll, the vascular network being configured for transporting the fluid in predetermined paths from the interior region to the exterior surface through a substantially radial path, the substantially radial path ending at an exit point of a fluid exit, wherein the exit point is associated with a sleeve exit.

Abstract: A web substrate having at least one ply is disclosed. At least one outer surface of the web substrate has indicia comprising at least one ink disposed thereon and substantially affixed thereto. The indicia comprise a first distribution of indicium having a halftone of a first value and a second distribution of indicium having a halftone of a second value. The first and second values are different.

Abstract: A contact printing system comprising a gravure cylinder having first, second, and third pluralities of discrete cells disposed in a respective first, second, and third distribution upon the outer surface of the gravure cylinder is disclosed. The first, second, and third pluralities of discrete cells each receives a respective first, second, and third portion of a respective first, second, and third fluid from a respective first, second, and third at least one channel disposed internal to the gravure cylinder. The first, second, and third at least one channels each have a single entry point at the respective first, second, and third positions external to the gravure cylinder and a discrete exit point at the respective first, second, and third plurality of discrete cells. The first, second, and third plurality of discrete cells are disposed adjacent each other and are randomly distributed upon the outer surface of the gravure cylinder.

Abstract: A contact printing system is disclosed. A gravure cylinder having a plurality of discrete cells disposed upon an outer surface thereof. A first portion of a first fluid and a second portion of a second fluid are disposed from a respective channel disposed internal to the gravure cylinder. The gravure cylinder, including the first and second at least one channels and the plurality of discrete cells, is formed so that the gravure cylinder has a unibody construction and has no moving parts interior to the gravure cylinder.

Abstract: A contact printing system for printing X colors upon a web substrate is disclosed. The contact printing system comprises X-Y printing components where X and Y are whole numbers, 0<Y<X, and X>1. Each of the printing components comprises a gravure cylinder having a plurality of discrete gravure cells disposed within a surface thereof. A first portion of a fluid is displaceable into a first portion of discrete gravure cells from at least one channel extending from a position external to the gravure cylinder.
