A process and a device for dewatering a fiber web, especially a paper web, using vacuum. The vacuum seen by a given unit are of the web is pulsed between a maximum value V and a minimum value. At least one suction boxis provided with perforations beneath the running web where the vacuum is applied with a pulsating effect on the web.

Process and device for dewatering a fiber web

A process for increasing the tactile properties of a base web without adversely effecting the strength of the web is disclosed. In one embodiment, the process includes the steps of placing a base web between a first moving conveyor and a second moving conveyor. The conveyors are then wrapped around a shear-inducing roll which creates shear forces that act upon the base web. The shear forces disrupt the web, increasing the softness and decreasing the stiffness of the web. The shear-inducing roll typically has a relatively small diameter. In some applications, more than one shear-inducing roll may be incorporated into the system. Base webs made according to the present invention have been found to have improved void-volume and fuzz-on-edge properties.
