In a method for manufacturing a belt and a belt for use in the production of bulk tissue and towel, and of nonwoven articles and fabrics, a polymeric resin material is applied onto the surface of a base substrate in a precise predetermined pattern which is to be imparted onto products manufactured with the belt. The polymeric resin material is deposited in droplets having an average diameter of 10μ (10 microns) or more. The polymeric resin material is then set by means appropriate to its composition, and, optionally, may be abraded to provide the belt with a uniform thickness, and a smooth, macroscopically monoplanar surface.

What is claimed is: 1. A method for manufacturing a belt for use in the production of bulk tissue and towel, and of nonwoven articles and fabrics, said method comprising the steps of; a) providing a base substrate for the belt; b) depositing polymeric resin material onto said base substrate in a controlled manner so as to control the x, y, z dimensions of the material deposited to create a predetermined pattern of deposits, wherein each deposit comprises one or more droplets of polymeric resin material; and c) at least partially setting said polymeric resin material. 2. A method as claimed in claim 1 wherein said droplets have an average diameter of 10μ (10 microns) or more. 3. A method as claimed in claim 1 wherein steps b) and c) are performed sequentially on successive bands extending widthwise across said base substrate. 4. A method as claimed in claim 1 wherein steps b) and c) are performed sequentially on successive strips extending lengthwise around said base substrate. 5. A method as claimed in claim 1 wherein steps b) and c) are performed spirally around said base substrate. 6. A method as claimed in claim 1 wherein, in step b), said predetermined pattern comprises a plurality of discrete locations set forth in a predetermined array. 7. A method as claimed in claim 1 wherein, in step b), said predetermined pattern comprises a continuous network defining a plurality of discrete open areas in a predetermined array. 8. A method as claimed in claim 1 wherein, in step b), said predetermined pattern comprises a semicontinuous network extending substantially throughout said base substrate. 9. A method as claimed in claim 1 wherein, in step b), said polymeric resin material penetrates into said base substrate. 10. A method as claimed in claim 1 wherein, in step b), said polymeric resin material forms a uniform or random pattern layer of desired thickness over said base substrate. 11. A method as claimed in claim 1 wherein, in step b), said polymeric resin material is deposited by a piezo-jet means. 12. A method as claimed in claim 1 wherein, in step b), said polymeric resin material is deposited by a piezo-jet array comprising a plurality of individual computer-controlled piezo-jets. 13. A method as claimed in claim 1 further comprising, between steps b) and c), the steps of: i) checking the actual pattern of said polymeric resin material to measure conformity to said predetermined pattern to measure conformity to said predetermined pattern; and ii) repairing said actual pattern of said polymeric resin material to eliminate departures from said predetermined pattern. 14. A method as claimed in claim 13 wherein said checking step is performed by a fast pattern recognizer (FPR) processor operating in conjunction with a digital imaging camera. 15. A method as claimed in claim 14 wherein said repairing step is performed by a repair-jet array coupled to said FPR processor. 16. A method as claimed in claim 1, wherein said polymeric resin material is selected from the group consisting of: 1. hot melts and moisture-cured hot melts; 2. two-part reactive systems based on urethanes and epoxies; 3. photopolymer compositions consisting of reactive acrylated monomers and acrylated oligomers derived from urethanes, polyesters, polyethers, and silicones; and 4. aqueous-based latexes and dispersions and particle-filled formulations including acrylics and polyurethanes. 17.

A method as claimed 10 wherein said polymeric resin material is deposited in a nonuniformly thick layer having a surface with a three-dimensional structure. 23. A method as claimed in claim 1 further comprising the step of depositing a polymeric resin material onto said base substrate in said predetermined pattern with a bulk jet to accelerate the manufacture of said belt. 24. A method as claimed in claim 23 wherein said depositing step is carried out prior to step c). 25. A method as claimed in claim 23 wherein said depositing step is carried out simultaneously with step c). 26. A method as claimed in claim 1 further comprising the step of abrading said polymeric resin material deposited on said base substrate to provide said polymeric resin material with a uniform thickness and a smooth, macroscopically monoplanar surface. 27. A method as claimed in claim 1 which includes the step of providing a base substrate taken from the group consisting essentially of woven, nonwoven, spiral formed, spiral-link, knitted, mesh or strips of material which are ultimately wound to form a belt having a width greater than a width of the strips. 28.
