Abstract:
A process for printing a web substrate in contacting engagement with an external surface of a central roll of a contact printing system is disclosed. The process comprises the steps of: a) providing the central roll with a plurality of cells disposed upon an outer surface thereof; b) providing a first fluid satisfying a first system of equations to a first of the cells from a position internal to the central roll; c) providing a second fluid satisfying a second system of equations to a second of the cells from a position internal to the central roll; d) contactingly engaging the web substrate with the external surface of said central roll and, e) fluidically displacing the first and second fluids from the first and second cells onto the web substrate.
Abstract:
A contact printing system is disclosed. The contact printing system has a central roll having a plurality of discrete cells disposed upon an outer surface thereof. Adjacent cells of the plurality of discrete cells each have a fluid disposed therein from a respective location internal to the central roll. Each fluid is disposable from each of the cells to a web substrate and provides a resultant color upon the web substrate having a 2-D gamut boundary represented by a defined system of CIELab equations.
Abstract:
A gravure printing system is disclosed. The gravure printing system has a central roll with a plurality of discrete cells disposed upon an outer surface thereof. A first of the plurality of discrete cells are capable of receiving at least one fluid and a second of the plurality of discrete cells are capable of receiving at least two fluids. Each of the fluids is fluidically displaced into the first and second cells from a position internal to the central roll.
Abstract:
An apparatus for the application of atomized fluid to a web material having a first surface and a second surface opposed thereto is disclosed. The apparatus is provided with a fluid source disposed adjacent to the first surface of the web material and a receipt plenum disposed adjacent to the second surface of the web material. The receipt plenum provides a source of negative pressure to the second surface of the web material. A fluid disposed from the fluid source contacts the first surface of the web material and is caused to traverse therethrough by the source of negative pressure. A portion of the fluid contacting the first surface of the web material is contained by the receipt plenum.
Abstract:
A web rewinding apparatus having a mandrel cawing assembly for releaseably engaging unsupported ends of a plurality of mandrels is disclosed. Each of the plurality of mandrels extends generally parallel to the web winding turret assembly axis. Each of the mandrels is driven in a closed mandrel path about the web winding turret assembly axis. The mandrel cupping assembly corn rises a cupping arm turret having a cupping arm turret central axis, a mandrel cup cooperatively associated with each mandrel of the plurality of mandrels, at least three motion limiting devices disposed upon the cupping arms, and a first actuator.
Abstract:
The present disclosure provides for an apparatus for transferring fluid. The apparatus has a fluid transfer component, a fluid receiving component, a fluid supply, and a fluid motivating component. The fluid transfer component comprises first surface, a second surface, a non-random pattern of distinct pores each defining a pathway between the first and second surfaces, each pathway having a single entry point at the first surface and a single exit point at the second surface. The pores are disposed at preselected locations to provide a desired pattern of permeability. The fluid receiving component comprises a fluid receiving surface. The fluid supply is adapted to provide a fluid in contact with and at a constant fluid pressure with each of said pores. The fluid motivating component is adapted to facilitate transport of the fluid from the first surface through the pores to the second surface.
Abstract:
An apparatus for embossing a fibrous structure is disclosed. The apparatus has a pattern roll and a patterned embossing belt. The pattern roll has a surface comprising a first pattern of protrusions and recesses The patterned embossing belt has a second pattern of protrusions and recesses. The first pattern of protrusions and recesses and the second pattern of protrusions and recesses are complementary. The pattern roll and the patterned embossing belt are matingly engageable to provide a lateral clearance, LC, greater than about 75 μm and a depth of mesh, DW, greater than about 254 μm.
Abstract:
Fibrous web substrates and a process for printing a series of different graphics in the manufacture of fibrous web substrates, such as tissue and towel products, utilize flexographic printing with endless belts and have graphic repeats of at least about 58 inches. In addition, these substrates have color to color MD registration of less than about 1.5 mm.
