- SlipNot® Safety Flooring was originally developed for fabricating platforms, decks, and other flooring surfaces.
- SlipNot® is also available for stair nosings, stair treads, ladder rungs and utility vault covers.
- SlipNot® Safety Flooring has a file hard surface that maintains its coefficient of friction after years of wear.

These advantages have led to the expansion of markets for SlipNot® Safety Flooring to include road plates used to cover trenches in roads, sidewalks and parking lots. Prior art road plates are generally uncoated steel plates that are placed over trenches in roadways as a temporary cover.

- the conventional method of manufacturing SlipNot® Safety Flooring begins with a new metal plate or grating that is cleaned and roughened in a shot blasting machine such as a large stationary Wheelabrator® machine. After cleaning and roughening the surface, the plate or grating section is loaded into a fixture having reciprocating weld guns and a power conveyor that is permanently lodged in a manufacturing facility.

Description
- This application is a division of U.S. application Ser. No. 10/386,270, filed Mar. 11, 2003, which in turn claims the benefit of U.S. Provisional Application Ser. No. 60/363,691 filed March 12, 2002.
- 1. Field of the Invention
- The present invention relates to a method of applying an anti-slip coating to plates and grates and to a portable manufacturing facility.
- 2. Background Art
- SlipNot® Safety Flooring manufactured by the W. S. Molnar Company is an advanced anti-slip and anti-skid coating that is applied to metal plate, metal grating, and other metal sections that are used in the fabrication of walking surfaces, vehicle traffic surfaces, and other work surfaces. SlipNot® Safety Flooring was originally developed for fabricating platforms, decks, and other flooring surfaces. SlipNot® is also available for stair nosings, stair treads, ladder rungs and utility vault covers.
- One of the advantages inherent in SlipNot® Safety Flooring is that it has a file hard surface that maintains its coefficient of friction after years of wear. Its anti-slip characteristics provide safe, secure footing even when wet or coated with oil or grease. These advantages have led to the expansion of markets for SlipNot® Safety Flooring to include road plates used to cover trenches in roads, sidewalks and parking lots. Prior art road plates are generally uncoated steel plates that are placed over trenches in roadways as a temporary cover. The coefficient of friction of the uncoated steel plate is substantially lower than the coefficient friction of the surrounding asphalt or cement road surface. Pedestrians, cars, bicycles, and motorcycles moving over road plates can lose traction that can lead to accidents.
- The conventional method of manufacturing SlipNot® Safety Flooring begins with a new metal plate or grating that is cleaned and roughened in a shot blasting machine such as a large stationary Wheelabrator® machine. After cleaning and roughening the surface, the plate or grating section is loaded into a fixture having reciprocating weld guns and a power conveyor that is permanently lodged in a manufacturing facility.
- Most companies that use road plates have an existing inventory of plates in a variety of sizes and shapes that are used repeatedly to temporarily cover trenches. Even though there is a growing demand for SlipNot® Safety Flooring road plates, the cost of shipping heavy road plates from a utility company or contractor's storage location to a central manufacturing facility and loss of the use of the plates while they are being transported to the coating location and returned are significant disadvantages.
- Some companies have even resorted to applying an epoxy and grit coating to comply with government safety standards. Epoxy and grit coatings are only temporarily effective due to the fact that the epoxy wears off over time. When epoxy coatings wear off or delaminate, the slippery underlying surface is re-exposed.
- The above disadvantages associated with the prior art are addressed by the present invention as summarized below.
- A truck trailer manufacturing facility is provided for coating workpieces such as metal plates or grating sections with a thermal spray anti-slip coating that provides a durable, high coefficient of friction surface on the workpieces. The method includes the steps of cleaning and roughening a surface of a workpiece with a surface preparing machine, loading the workpiece into a coating machine housed in a truck trailer, and applying a coating to the surface of the workpiece. In addition, the method may include the steps of indexing the workpiece to an unloading platform disposed outside the truck trailer and cooling the workpiece on the unloading platform.
- The manufacturing facility may include at least one machine for preparing the surface of a workpiece and at least one coating machine. The surface preparation machine, which may be house in a truck trailer, may be a shot blasting machine, a scarifier or a grinding machine.
- The coating machine may be a welding gun having automatic wire feed and compressed air for directing the thermal spray. The welding gun may be indexed across the workpiece as the workpieces move through the coating machine on power operated conveyors. In addition, the workpiece may be indexed through the truck trailer as the coating is applied. The coating machine may be housed within a booth located inside the truck trailer that confines the exhaust from the welding operation including dust and products of combustion and is ducted to a filtration section that cleans the exhaust prior to venting to the atmosphere.
- The truck trailer may be provided with storage compartments for welding wire, surface preparation machines, and supplies. An air compressor and motor generator set may be separately provided or included as part of the manufacturing facility. Electrical wiring and piping for compressed air may be incorporated in the truck trailer including external connections for power and compressed air that may be obtained from stationary or portable sources.
- The coating may be formed from welding wire comprising plain steel wire, cored wire having high carbon content, aluminum wire, stainless steel wire or nickel alloy wire.
- These and other aspects and advantages of the invention will become apparent upon review of the attached drawings in light of the following detailed description of the invention.

second coating booth 14′, a surface preparationmachine storage area 56 may be provided. The surface preparation machine storage area can be used to store a plurality ofsurface preparation machines 22 as well as supplies for the machines. Aramp 58 is preferably provided at the rear of thetrailer 12 to facilitate loading and unloading thesurface preparation machines 22 and other supplies into thestorage area 56. - While the illustrated embodiment shows two
coating booths smaller coating booths 14 in the trailer. The location of the various elements of the manufacturing facility may be changed. While thesurface preparation machines 22 illustrated are portable machines, it is also anticipated that it may be possible to use a surface preparation machine that could be mounted in thetrailer 12 through whichplates 24 could be indexed in a manner similar to the way that that theplates 24 are moved through thecoating booths - The method of the present invention will be described below. A
plate 24 or metal grating section is first placed on the ground, a support member, or floor of thetrailer 12. Thesurface preparation machine 22 is placed on theplate 24 to clean and roughen the surface of theplate 24. Theplate 24 is then placed on theloading platform 16 and fed into thecoating booth 14. Thewelding machine 40 applies a metalized anti-slip coating on the cleaned surface. Theplate 24 is indexed on a power conveyor through thecoating booth 14 as the coating is applied. After applying the coating the plate is indexed out of the coating machine to theunloading platform 46 on which thecoated plate 24′ may be cooled and then removed to storage. - While embodiments of the invention have been illustrated and described, it is not intended that these embodiments illustrate and describe all possible forms of the invention.
