Definitions
- the reinforcing element has a first side and an opposite second side.
- the reinforcing element comprises a fluid-permeable element, such as, for example, a woven fabric or a screen having a plurality of open areas therethrough.
- the reinforcing element may also comprise a felt, as for example disclosed in commonly assigned US patents 5,629,052 and 5,674,663, incorporated herein by reference.
- a process for making a papermaking belt includes the following steps: providing a reinforcing element; providing an extrudable resinous material; providing at least a first extrusion die; supplying the resinous material into the extrusion die and extruding the resinous material onto the reinforcing element such that the resinous material and the reinforcing element join together, preferably the resinous material forming a preselected pattern on the reinforcing element; and solidifying the resinous material joined to the reinforcing element.
- the resinous material can be extruded onto a forming surface, and then be transferred to the reinforcing element.
- the resinous beads extruded onto the reinforcing element may have general orientation in the machine direction, or in the direction substantially orthogonal to the machine direction including any direction which forms an acute angle with the machine direction.
- the combined movement of the reinforcing element (or the forming surface) and the extrusion die or dies preferably produces a resulting velocity vector having a machine- directional component and a cross-machine-directional component.
- the movement of the reinforcing element (or the forming surface) and the movement of the extrusion dies is designed to mutually cooperate such that the resinous material extruded upon the reinforcing element forms a pre-selected, preferably repeating, pattern.
- the beads may have a waving configuration, or be straight. Also, the beads may have differential height.
- the patterned resinous framework may have a semi-continuous pattern, or a pattern also comprising a third plurality of discrete protuberances outwardly extending from the reinforcing element.
- the resinous beads comprise a material selected from the group consisting of epoxies, silicones, urethanes, polystyrenes, polyolefins, polysulfides, nylons, butadienes, photopolymers, and any combination thereof.
- FIG. 9 is a schematic plan view of one exemplary embodiment of the papermaking belt comprising a resinous framework having a semi-continuous pattern.
- FIG. 10 is a schematic plan view of another exemplary embodiment of the papermaking belt comprising a resinous framework having a continuous pattern and a pattern comprising a plurality of discrete protuberances.
- FIG. 12 is a schematic plan view of another exemplary embodiment of the papermaking belt comprising a resinous framework having a continuous pattern.
- FIG. 16 is a partial cross-sectional view of a fragment 16 of FIG. 14.
- a representative papermaking belt , or clothing, also known as a "molding template,” which can be made in accordance with the present invention is schematically shown in FIGs. 4, 5, and 9-13.
- the term "papermaking belt,” or simply “belt,” refers to a substantially macroscopically-monoplanar structure designed to support, and preferably carry, a web thereon during at least one stage of a papermaking process.
- modern industrial-scale processes utilize endless papermaking belts, but it is to be understood that the present invention may be used for making discrete portions of the belt or stationary, as well as rotary, plates which may be used for making web handsheets, rotating drums, etc.
- the reinforcing element 50 can take any number of different forms. It can comprise a woven element such as for example, a screen, a net, etc., or a non-woven element, such as, for example, a band, a plate, etc.
- the reinforcing element 50 comprises a woven element formed by a plurality of interwoven yarns, as shown in FIGs. 3, 9, 11, 12, 13, 15, and 16. More particularly, the woven reinforcing element 50 may comprise a foraminous woven element, such as disclosed in commonly-assigned U.S. Patent No. 5,334,289, issued in the name of Trokhan et al., on August 2, 1994, and incorporated by reference herein.
- a design that is particularly preferred for making structured paper is a composite structure comprising a reinforcing element 50 and a patterned framework 300, as discussed above.
- a particularly preferred reinforcing element 50 is a woven fabric shown in FIGs. 3, 9, 11, 12, 13, and 15-17. Woven fabrics are preferred as reinforcement because of their strength to weight ratio and because they effectively distribute potentially damaging strains induced by the papermaking process without failing.
- Woven materials are particularly good at distributing such strains by skewing, that is, distorting in the plane of the weave without going out of plane (ridging).
- a ridged belt is quickly destroyed as it goes through mechanical nips or wraps around small- diameter rolls; both the mechanical nips and the small-diameter rolls are common on paper machines.
- the ability of the woven reinforcing element to skew and hence avoid catastrophic ridging is significantly affected by the way the patterned framework is attached. If the patterned framework is continuous (as, for example, those best shown in FIGs. 4, 5, and 10-12) and integrally intermeshed with the woven secondary over its entire projected area, the skewability of the composite is significantly reduced.
- the resinous beads of the first plurality 110 overlap, or cross-over, the resinous beads of the second plurality 120, thereby forming the plurality of the super-knuckles 160 at the points of contact 150 and a plurality of the deflection conduits 350 intermediate the points of contact 150.
- the super-knuckles 160 are distributed throughout the belt 90 in a preselected pattern.
- FIG. 13 shows that the beads of the first plurality 110 has a first thickness A1 , and the beads of the second plurality 120 has a second thickness A2.
- the super-knuckles 160 have a third thickness A3 which is preferably greater than either one of the first thickness A1 and the second thickness A2. It is to be understood that depending on a particular design of the belt and desired characteristics of the paper, the first thickness A1 may be equal to the second thickness A2, or - alternatively - be different therefrom.
- a first step comprises providing a forming surface 30.
- the "forming surface” is a surface onto which the resinous material is deposited to form the resinous framework 300.
- the forming surface comprises the first surface 51 of the reinforcing element 50.
- the forming surface 30 comprises a top surface of an endless band traveling around rolls 21 and 22.
- the forming surface 30 comprising the reinforcing element 50 is supported by an endless support band 20.
- the support band 20 is supported, in turn, by an endless auxiliary band 30a (traveling around rolls 31 and 32) in the zone of forming the resinous framework.
- the reinforcing element 50 is a substrate that may comprise a variety of different forms, such as, for example, a woven fabric, a felt, a screen, a band, etc.
- a more detailed description of the reinforcing element 50, particularly one comprising a woven element, is found in commonly-assigned U.S. Patent 5,275,700 incorporated herein by reference. Regardless of its specific embodiment, the reinforcing element
- cross-machine direction is a direction perpendicular to the machine direction and parallel to the general plan of the papermaking belt being constructed.
- the forming surface 30 further has a longitudinal direction and a transverse direction.
- the longitudinal direction is any direction which lies within the range of less than ⁇ 45° relative to the machine direction
- the transverse direction is any direction which lies within the range of ⁇ 45° relative to the cross- machine direction.
- the flowable resinous material of the present invention may comprise a material selected from the group consisting of: epoxies, silicones, urethanes, polystyrenes, polyolefines, polysulfides, nylons, butadienes, and any combination thereof.
- the resinous material is extruded onto the forming surface 30 in a pre-selected pattern.
- the pattern may be formed by moving at least one of the forming surface 30 and the extrusion die 100.
- the forming surface is continuously traveling in the machine direction MD at a transport velocity.
- the extrusion die 100 is stationary (i. e., does not move) the resulting pattern of the resinous material disposed on the forming surface 30 comprises a substantially straight lines (not shown). If, however, the extrusion die or dies move relative to the forming surface 30, for example in the cross- machine direction CD, as shown in FIGs.
- the resulting resinous framework 300 comprises a plurality of deflection conduits 350 formed between the adjacent resinous beads and the points of contact 150 thereof.
- the resinous beads overlap at points of contact 150 thereby forming the super-knuckles 160, discussed above.
- Present invention also contemplates using at least two different chemically-active resinous materials, as defined above.
- the first extrusion die 100 is extruding the first plurality of the resinous beads comprising the first chemically-active material
- the second extrusion die 200 is extruding the second plurality of the resinous beads comprising the second chemically-active material.
- the first and second pluralities of the resinous beads contact when disposed on the forming surface 30.
- the first chemically-active material comprising the first plurality of the beads and the second chemically-active material comprising the second plurality of the beads cross-link at the points of contact. It is believed that a sufficiently secure connection could thus be formed between the first and second pluralities of the resinous beads.
- the embodiment of the resinous framework 300 shown in FIG. 18 comprises the super-knuckles 160, as discussed above.
- FIG. 18 also shows the embodiment of the process in which the resinous framework 300 and the reinforcing element 50 in contact therewith are impressed together between the rolls 51 and 52 to the extent that allows the reinforcing element 50 only partially join to the resinous framework 300, i. e., the reinforcing element 50 joins primarily to the super-knuckles 160.
- a nip between the calendering rolls 51 and 52 may be chosen such that the reinforcing element 50 and the resinous framework 300 join together by way of the super-knuckles 160 being joined to the reinforcing element 50.
- Pre-solidification of the resinous material may begin as early as immediately after the fluid resinous material has been deposited onto the forming surface 30 to form the resinous framework thereon.
- a method of solidifying the resinous material depends upon its nature. If a thermoplastic or thermosetting resin is used, solidifying comprises cooling the resinous material.
- Photopolymer resins may be cured by a process of curing described in commonly assigned U.S. Patents 4,514,345; and 5,275,700, incorporated herein by reference and referred to above.
- the resinous material comprising multi-component resins or plastics may solidify naturally, during a certain predetermined period of time, by virtue of being mixed together.
- the process and the apparatus of the present invention significantly reduces the amount of the flowable resin that is required to be used in constructing the belt 90, and thus provides an economic benefit.
- the prior art's methods of making the belt, using a photosensitive resin and a curing radiation requires application of a coating of the photosensitive resin to the reinforcing element, curing selected portions of the resinous coating, and then removing (typically, washing out) uncured portions of the resinous coating.
- the amount of the resin being washed out may be as high as 75% relative to the amount of the entire resinous coating.
- the exact amount of the resinous material, which is required for the resinous framework 300 can be formed on the forming surface 30.
- the process and the apparatus of the present invention allows one to create virtually unlimited number of patterns of the resinous framework 300.
