Patent number: 11717847Abstract: An adhesive application apparatus is provided. The apparatus uses a rolled on adhesive applied to a substrate. After roll application, an adhesive activator is sprayed onto the substrate. By spraying an activator onto the substrate after the adhesive is applied, the adhesive may be made tacky for adhesion, but the adhesive used for rolling may be highly stable and slow to dry/cure without said activator, which enhances rolled application effectiveness.Type: GrantFiled: October 21, 2020Date of Patent: August 8, 2023Assignee: Worthen IndustriesInventors: Steven E. Adams, Andrew T. Sinclair, Robert J. Rose, Ian L. Churcher

Patent number: 11174414Abstract: The present invention involves a 100% solids, radiation curable adhesive formulation for adhesion to EVA. This formulation may have varying compositions, as discussed in detail herein. However primarily the composition may comprise at least a monomer, and a chlorinated additive. Photo initiators may be used to allow for low temperature UV or other radiation curing. Other additives may be used to enhance functional features in various ways. In use, the present invention may be coated on a surface of EVA and then cured, and may be adhered to a substrate using only a layer of adhesive on the substrate, in contrast to the structures of the prior art, which require at least two sided adhesive application, among other complexities.Type: GrantFiled: January 3, 2019Date of Patent: November 16, 2021Assignee: Worthen IndustriesInventors: Bob Chang, Vincent Chevalier

Patent number: 11097493Abstract: A foam assembly system is provided. The system is configured to heat a surface of foam. After the heating of the foam, an adhesive is applied, typically a high solids adhesive. The foam is then bonded to another foam surface. It has been found that the pre-heating of the foam before adhesive application greatly enhances the bond strength between the foam and the second foam surface to which it is adhered.Type: GrantFiled: May 19, 2020Date of Patent: August 24, 2021Assignee: Worthen IndustriesInventors: Robert J. Rose, Andrew T. Sinclair, Ian L. Churcher

Patent number: 11059062Abstract: The present invention provides an airless adhesive spray gun that atomizes adhesive sprayed through it without the use of air atomization. This system provides numerous enhancements to the prior art including limiting overspray “fog,” saving on sprayed material because of a more efficient spray pattern, and providing a stronger bond than that of the air-atomized spray guns of the prior art.Type: GrantFiled: February 19, 2015Date of Patent: July 13, 2021Assignee: Worthen IndustriesInventors: Steven E. Adams, John C. Hannon, Terry Nelson, Ian L. Churcher, Andrew T. Sinclair

Patent number: 10975270Abstract: A two component sprayable adhesive and system for spraying is provided. The two component adhesive may have an adhesive, and an activator. These components are mixed after spraying, either in the air or on a substrate. The activator destabilizes the adhesive making it more tacky and effective. In at least one of the two components, an additive is provided to provide a visual indication that the components are mixed and/or properly mixed in the intended ratio.Type: GrantFiled: November 9, 2018Date of Patent: April 13, 2021Assignee: Worthen IndustriesInventors: Ian L. Churcher, Steven E. Adams

Patent number: 10898918Abstract: A holster for a spray gun is provided. The holster is configured to hold a spray gun in place when not in use. The holster has a reservoir body that defines an open-topped chamber. A fluid may be held inside the chamber, and a nozzle of the spray gun held by the holster may submerge in this fluid. The nozzle being submerged in the fluid of the holster can prevent hardening, thickening or drying of any material left over on or in the spray gun nozzle after use.Type: GrantFiled: January 21, 2019Date of Patent: January 26, 2021Assignee: Worthen IndustriesInventors: Robert J. Rose, Steven E. Adams, Andrew T. Sinclair

Patent number: 10502485Abstract: A foam drying apparatus is provided. The apparatus is configured to pass air, and in some cases heated and/or dried air, through a quantity of foam. This air passing through the foam absorbs or otherwise carries moisture out of the foam, drying it. The apparatus may utilize a pressure differential on opposite sides of the foam, causing air on the higher pressure side to pass through the foam. Typical applications may include the drying of foam assemblies which use water based adhesives to accelerate drying of the adhesive and/or removal of water from the foam assembly, and packaging of the foam assembly.Type: GrantFiled: April 20, 2018Date of Patent: December 10, 2019Assignee: Worthen IndustriesInventors: Steven E. Adams, Andrew T. Sinclair, Robert J. Rose, Ian L. Churcher

Patent number: 10493474Abstract: A two part adhesive spray system is provided herein. This system provides numerous enhancements to the prior art including limiting overspray “fog,” saving on sprayed material because of a more efficient spray pattern, and providing a more efficient bond than that of the prior art. In particular, the present invention provides a spray pattern having both adhesive and activator. The activator is sprayed in a smaller spray area than the adhesive, which is sprayed on a larger area. As such, when sprayed on a substrate, the activator provides a rapid tack to hold a second adhered material to the substrate sufficient to hold it in place while the remainder of the adhesive dries and/or cures.Type: GrantFiled: December 15, 2016Date of Patent: December 3, 2019Assignee: Worthen IndustriesInventors: Robert J. Rose, Andrew T. Sinclair
