The present invention provides an adaptive control system to control a plant using direct output feedback in which a function of the full plant state, as opposed to estimates thereof, is used for feedback control of the plant. The adaptive control system of this invention is therefore highly useful in the control of plants, particularly plants for controlling the physical properties of rolls of web material and more particularly a calendering apparatus. Accordingly, in a particularly preferred embodiment the adaptive control system of this invention controls loading of a calender apparatus, such as a pair of opposed rolls forming a calendering stack, based upon the physical properties of a previously processed web.

Adaptive sheet caliper control system and apparatus and methods

An apparatus for perforating sheet materials is disclosed. The apparatus includes a perforation blade that defines a plurality of teeth for perforating sheet materials, such as tissue products. Each tooth on the perforation blade is defined by a pair of opposing side walls. The teeth are separated along an edge of the perforation blade by a plurality of recesses. In accordance with the present disclosure, the side walls have a non-zero angle with respect to the length direction of the blade. In one embodiment, each recess can have a slanted U-shape such that all of the side walls are parallel. In an alternative embodiment, the recesses can have a V-shape such that adjacent side walls extend in divergent directions. Perforation blades made according to the present disclosure prevent snagging and picking when a material is perforated.

Perforation blade for perforating tissue products

A device including blades and pins is mounted for interaction with a bedroll for separating or cutting a web or sheet of material as the web travels around the circumference of the bedroll. The assembly comprises a clamp having a bottom side and a front side. Two blades having an upper surface and a lower surface are provided, with a blade spacer located between the blades, and operably connected to the clamp. A blade from a nearby chopper roll is adapted to engage the blades of the device to separate a sheet as it travels along the processing pathway. A unitary elongated mandrel that is fixed in relation to the blade, and configured to carry or move a severed web, is provided. The unitary mandrel employs a strut from which projections or pins extend in a line or row, the pins being adapted to pierce and carry the severed tail of the web to a core for gluing the tail to the core, followed by winding.
