The winding mechanics of laminate webs, TAPPI Journal February 2020

ABSTRACT: Models that describe the residual stresses due to winding single-layer webs at the end of roll-to-roll manufacturing machines are mature. These models have been used to reduce or avoid defects that are due to winding. Many laminated products exist where two or more webs have been joined to form a thicker composite web. The properties of the web layers provide a unique functionality to the product being manufactured. No laminate winding models exist in the literature. This paper will focus on the development of a laminate winding model and laboratory test verification of the model.

Equilibrium moisture content in wet pressing of paper, TAPPI Journal July 2020

ABSTRACT: Equilibrium moisture is a limiting factor in achieving high solids in the later stages of pressing or pressing low basis weight grades. We have developed a model that relates equilibrium moisture directly to the pore size distribution of fibers as measured by the solute exclusion technique. The model shows that chemical pulping and refining increase equilibrium moisture by increasing pore volume at given pore sizes in fibers, which leads to lower pressed solids and greater energy expenditure in the dryer section. Means to increase equilibrium moisture without compromising pulp strength are briefly discussed.

Wet pressing and product quality: Review of previous pilot machine trials, TAPPI Journal July 2020

ABSTRACT: The purpose of wet pressing is to remove water by mechanical means to consolidate the web and minimize the energy expended in the dryer section. In this process, paper is compacted and densified to degrees that impact end-use performance. Average density is increased by pressing, which has implications for grades where stiffness is important. The z-direction density gradients can affect printing and converting. Lastly, pressing affects surface quality of paper and its response to printing. Broadly speaking, the final press nip dominates the paper surface roughness and the early press nips affect printing performance.
