US 7,005,044 B2 · Method of fabricating a belt and a belt used to make bulk tissue and towel, and nonwoven articles and fabrics

Abstract

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.

Dependent claims

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.
