example 1

[0036] A nonwoven fabric for a corrugator was manufactured and constructed using polyester helices with a diameter of 0.90 mm and hinge pins with a diameter of 0.90 mm. Stretching and heat setting were performed at 48 pli and 210°C. After this was measured, a static control yarn (carburized nylon) having a diameter of 0.52 mm was inserted into the helix. The fabric was cut to the final dimensions of the customer's corrugator and then coated with a 1" conductive edge coating on each lateral edge in the form of a conductive carburized synthetic rubber. A silicon traction coating was applied to the The area adjacent to and between the conductive edge coatings covers the remainder of the base fabric and extends a distance of approximately 2 to 6 mm above the base fabric. The silicone rubber compound is then heat cured at 175°C, 48 pli.

Abstract

The invention discloses an industrial fabric with a traction coating. An industrial fabric used in the manufacture or processing of at least one material web includes a base fabric having a board side and a machine side. The base fabric includes a plurality of spirals extending in a cross machine direction (CMD). The spirals are interconnected together with each other along adjacent peripheral edges to form a spiral link fabric. The base fabric has opposite lateral side edges extending in a machine direction (MD). One or more electrostatic control yarns are positioned within a corresponding spiral and extend in the CMD direction to the lateral side edges. A pair of conductive edge coatings is applied to at least the board side of a respective lateral side edge for a predetermined width. The conductive edge coatings and the one or more electrostatic control yarns form an electrostatic grid. A traction coating covers substantially all of at least the board side of the base fabric, but does not cover the pair of conductive edge coatings. The traction coating has a coefficient of friction greater than approximately 2 on the board side.

Description

technical field [0001] This invention relates to papermaking, and more particularly to corrugator "bottom belt" fabrics used in the process of making corrugated board or in the process of making cardboard in a double-backed cardboard machine. Background technique [0002] Static electricity builds up during manufacture and use of most fabrics made from monofilaments. The accumulated static electricity can cause occasional spontaneous electrostatic discharge (ESD). ESD can damage not only the paper structural product in production, but also irreparably damage the fabric used in the manufacture of the paper structural product. This would result in expensive fabric replacements and downtime of manufacturing equipment. In the worst case, it could damage the machinery that makes the paper structure products, or cause a fire. [0003] One example of a product class made using nonwovens is corrugated cardboard. The sheets of faceboard and corrugating core are converted to corru...
