A method for treating a substrate is described. In accordance with one aspect, the method includes applying a polymer coating to a substrate, and bringing the polymer coating into contact with a heated surface in a pressure nip while the coating is still in a wet state. Optionally the polymer coating may include a crosslinkable material, and a crosslinking agent may be used to promote crosslinking. The polymer coating replicates the heated surface. A product produced in accordance with the described method is also disclosed. The product is characterized by having subsurface voids within the coating.

A container body with a container opening and a flap partially secured to the container body and completely covering the container opening is disclosed. The flap is secured to the container by a hinge or fold line and formed from the same substrate as the container body. The container body contains a first magnetic region adjacent to and surrounding the perimeter of the container opening. The flap contains a second magnetic region aligned with and opposite the container body's first magnetic region. The first and second magnetic regions are magnetically attracted to each other. The flap is held in a closed position by magnetic attraction between the flap's magnetic region and the container body's magnetic region.

This invention relates to a loose draw detector for a paper machine wet press. Such structure of this type, generally, use laser triangulation displacement sensors mounted and positioned to measure the point of web release from the center roll and measure paper web wrinkles in the form of rapid fluctuations/decreases in the standoff distance between sensors and the web passing over the leadout roll to determine loose draw.

This invention relates to coater blades which are employed in papermaking machines. Such structures of this type, generally, employ a continuous coater blade located across the width of the papermachine which provides a new section of blade at desired rates or intervals.

This invention relates to load adjustment systems for coater blades. Such structures of this type, generally, employ the use of an actuator assembly to control cross-direction (widthwise) coatweight profiles.

This invention relates to sleeves or belts which are used in paper machines. Such structures of this type, generally, are reinforced through the use of reinforcing fibers which are oriented at an angle turned 45.degree. from the straight machine direction orientation. This arrangement aligns the individual reinforcing strands in the direction of the principal tensile stresses that exist within the sleeve or belt structure as the sleeve or belt is being rotated in the paper machine.

This invention relates to an apparatus and method for measuring the peel strength of a paper joint which is adhesively bonded. Such structures of this type, generally, allow the peel strength of the adhesively bonded joint to be accurately and repeatably measured in an inexpensive manner.

Complete definition of a papermachine headbox slice opening requires the measurement of three interdependent dimensions including (1) the projection distance of the slice lip edge below the slice beam, (2) the projection distance of the slice apron edge beyond the plane of the slice lip edge and (3) the slice opening distance between the slice lip edge and the upper face plane of the slice apron. A single gauging tool is provided for measuring all three headbox slice dimensions.
