Abstract: Sheets to be coated with water-based coating material, for example a primer and a low adhesion backsize, are supplied from a feeder (1), in end-to-end overlapping relationship, to a dual coater (3) in which the sheets are coated individually on both sides. A sheet inserter (2) is provided, upstream of the dual coater, to insert sheets from a second supply into the sheets from the feeder (1). The dual coated sheets are dried as individual sheets or as a pseudo-web of overlapped sheets. The sheets are then overlapped, unless previously overlapped, and the direction of overlap changed, if necessary, to provide the trailing edge of each sheet on top of the leading edge of each succeeding sheet. The overlapped sheets are conveyed through an adhesive transfer station (7) where stripes (236) of at least partially dried adhesive are coated onto the dual coated sheets from a transfer belt (71).

Abstract: A pre-metering rod is located between a coating applicator and an air knife, and replaces the smoothing roll in some existing air knife applications. The pre-metering rod consists of a small diameter rod of about one and one-half inches in diameter that rotates at 10-500 rpm against the direction of the coating layer on the web. The web is wrapped around a portion of the circumference amounting to about twenty-five degrees of the rod's surface as it travels over the rod. The rod is supported in a rod holder supported on a support beam. Actuators move the support beam away from the web for threading and maintenance, and towards the web to engage the rod with the web. The combination of the rod diameter, the amount of wrap on the rod, and the speed of the rod rotation determine the amount of pre-metering of the coating, which determines the thickness of the coating layer on the web that is presented to the air knife section. As a result, the thickness of the coating layer can be decreased.

Abstract: The process and apparatus of the present invention teaches how to treat a well-integrated woven or non-woven web of hydrophobic fibers to make selective areas hydrophyllic. It also can be used to make a web of hydrophyllic fibers selectively hydrophobic. It uses a plurality of selectively adjustable covers on an applicator roll rotating in a bath of liquid to place the liquid material on selective areas of the moving web. In a preferred embodiment the web is non-woven and the fibers are hydrophobic in nature, e.g., dry-laid or melt-blown polypropylene or polyethylene fibers or spun-bonded hydrophobic filaments. A woven web made of cotton or other hydrophyllic fibers may also be used if the end result is to create partially hydrophobic areas on a hydrophyllic web. The areas of liquid are positioned on the web only where desired so as to eliminate the excessive cost of unwanted and unnecessary coating material. If the web is hydrophobic, the liquid makes that area hydrophyllic.

Abstract: The present invention is an improved flywheel for damping vibrations in a coating roll. The improved flywheel has an inner plate and an outer plate and sandwiched between the two plates are alternating rings of a solid body material such as aluminum or steel and conventional vibration damping material. Typically, the flywheel is attached to the coating roll outside of the bearing mounting block. The flywheel is designed such that movement of the inner and outer plates relative to each other works to compress the damping material sandwiched between the two plates. The plates are fastened together so that torsional motion between the plates, alternating rings, and coating roll is prevented. This compression of the damping material results in the absorption and dissipation of vibrational energy of the radial bending of the coating roll.

Abstract: A coating system for material webs, specifically of paper or cardboard, includes two mutually parallel rolls directly coordinated with each other, the rolls having a mutually variable spacing such that the rolls can be positioned to create a press gap for coating the web, or so as not to create a press gap. When the rolls are not positioned to form a press gap, the web passes over both roll shells while circumventing the applicators which have already dosed the roll shells with a coating mixture. The web passes over both roll shells for purposes of transferring the coating mixture predosed by the applicators. Solely the web pull in conjunction with the wrap angle of the two roll shells serves the final dosing by scraping off an excess quantity from the roll shells.

Abstract: A magnetizable layer can be applied to a flexible backing web by gravure coating at high speeds by independently driving the backing web at a speed that is substantially different from the surface speed of the gravure roll.

When that backup roll has a hard surface such as metal, its surface can be machined with precision, and that precision can be maintained in spite of exposure to solvent vapors.
