Paper forming is the first step in the paper machine where a fiber suspension leaves the headbox and flows through a forming fabric. Complex physical phenomena occur as the paper forms, during which fibers, fillers, fines, and chemicals added to the suspension interact. Understanding this process is important for the development of improved paper products because the configuration of the fibers during this step greatly influences the final paper quality. Because the effective paper properties depend on the microstructure of the fiber web, a continuum model is inadequate to explain the process and the properties of each fiber need to be accounted for in simulations. This study describes a new framework for microstructure simulation of early paper forming. The simulation framework includes a Navier-Stokes solver and immersed boundary methods to resolve the flow around the fibers. The fibers were modeled with a finite element discretization of the Euler-Bernoulli beam equation in a co-rotational formulation. The contact model is based on a penalty method and includes friction and elastic and inelastic collisions. We validated the fiber model and the contact model against demanding test cases from the literature, with excellent results. The fluid-structure interaction in the model was examined by simulating an elastic beam oscillating in a cross flow. We also simulated early paper formation to demonstrate the potential of the proposed framework.

Fiber suspension simulations are challenging since they involve transient fluid flow with immersed solid objects subject to large displacements and rotations. In the present work, a beam model in corotational formulation is coupled with a fluid solver using immersed boundary methods. The model is used to simulate a fiber in a shear flow and excellent agreement is found with Jeffery's equations. The shapes of fibers deforming in a shear flow are found to be in qualitative agreement with shapes observed in experiments. The flow of a fiber suspension is studied by simulating early paper forming with one-way and semi-two-way coupling. It is found that the flow through the fiber web needs to be resolved in order to predict the retention of fibers in the fiber web.

3D structures for composites, and especially 3D woven preforms use, is growing because of high-performance fibres improvements, field diversification and applications complexity. Critical industries like the air-space industry need a perfect control of processes and products’ final properties. Among other 3D weaving techniques, multilayer weaving is interesting for the diversity and complexity of possible 3D structures. A new Jacquard shedding technology called UNIVAL 100 which can be used with multilayer weaving, has appeared few years ago and uses actuators instead of the traditional Jacquard hooks. It is synonym of great improvements, as such a technology should enable controlling perfectly the way yarns are moving during shedding. The aim of this paper is first to describe their operating mode. It is our basis for a design of experiments development, the purpose of which is to experimentally determine the effects of UNIVAL parameters on process quality, in the case of high-density multilayer woven fabrics (which we will further call HDMW fabrics). © 2015, © The Author(s) 2015.

Paper machine clothing (PMC) has been an important contributor for energy savings in paper and board machines. Companies have to find more innovative ways of providing value to customers through product and service and analyze in more detail the impact products have on a customer's process. The 30% increase in nip dewatering could lead to the reduction in use of one vacuum box in a press section, leading to significant savings in power consumption. If a paper machine uses a data historian which stores thousands of pieces of data every second, detailed multivariate data analysis can be completed. However, even with a simple data stream recorded daily for trial monitoring can allow the use of simple six sigma statistical analysis and can be extremely rewarding. There are a great variety of different ways in which updates in best practices can be accomplished, through web based forums, through reporting but mainly through the application of standard operating procedures and condition monitoring in mills.

IR cameras can be used in paper mills to find web profile issues, steam leaks, and machine hot spots. The IR camera needs to be set up for proper image capturing. Once an image is captured the thermographer needs to know how to interpret the temperature variances. • First, the thermographer needs proper tools to calibrate the IR camera for capturing images. Proper reference temperatures and humidity can be set using a relative humidity gauge, a piece of aluminum foil, and a piece of cardboard. Some other tools can be used to set the distance from the target area. • Second, the tfiermographer needs to use the proper angle to the target. Also, the camera also needs to be in focus for the image to be of any value. • Finally, the thermographer needs to interpret the image. Some knowledge of the paper machine is required to make a correct interpretation or ask the proper questions to come to the correct conclusion. Other tools may be needed for additional information as well.

Dozens of press operating parameters are routinely measured both on-line and with portable instruments. While many paper machines have extensive collections of data, sometimes the information is not extensively used. This paper will discuss how and why some measurements are made, and what advantages can be gleaned from them.
