Abstract [en]

In the present work we propose a particle approach, which is designed

to treat complex mechanics and dynamics of the open-draw sections that

are still present in many of today's paper machines. First, known

steady-state continuous solutions are successfully reproduced. However,

it is shown that since the boundary conditions depend on the solution

itself, the solutions for web strain and web path in the open-draw

section are generally time-dependent. With a certain set of system

parameters, the nonsteady solutions are common. A temporal fluctuation

of Young's modulus, for example, destabilizes the system irreversibly,

resulting in the continuous growth of web strain, i.e., break. Finally

we exemplify with some strategic draw countermeasures how to prevent a

dangerous evolution in the web strain.
