The present disclosure relates to the application of adhesive sheet materials, and, more particularly, an arc squeegee and method for applying adhesive sheet materials.
Adhesive sheet materials are becoming the increasingly popular choice for advertising or otherwise displaying graphics on signs, automobiles, indoor and outdoor walls, indoor and outdoor floors, indoor and outdoor ceilings, buildings, and numerous other surfaces. Adhesive sheet materials typically have a display side bearing desired graphics, colors, texture, images, and/or text, and an application side that is coated with an adhesive substance and allows for application to various surfaces. The adhesive sheet material is typically applied in oversized sections and then cut or shaped to the desired shape and size. The size of the oversized sections and the size of the surface to which the adhesive sheet material is being applied vary greatly depending on the application.
One type of adhesive sheet material, which is commonly used in the vehicle wrap industry is vinyl paint wraps. Although vinyl paint wraps are common, vehicles can be customized using a variety of adhesive sheet materials and the customization can include, but is not limited to including, body color change and/or texture change.
Adhesive sheet materials are applied to surfaces that have a variety of unique features, such as contours, welded obstacles, edges, texture, and elements such as handles or windows. It is desirable to shape the adhesive sheet material around the surfaces' unique features. The adhesive sheet material is best applied once gently heated during the application process, the heat serving both to activate the adhesive and to render the adhesive sheet material more pliable and thus amenable to compliance with the application to the surface and its unique features. Generally, a heat source, such as an electric heat gun, a propane torch or other combustible gas torch is used to heat the adhesive sheet material. Typically, an electric heat gun is primarily used with a gas torch secondarily, as vinyl sheet material normally does not require a lot of heat while installing with the squeegee of the present invention.
Application of adhesive sheet material is a pressure sensitive process. Applying the wrong amount of pressure can result in improper installation of the adhesive sheet material. Difficulties often arise during application of adhesive sheet material to variations in the surface or irregular surface features, such as contours, welded obstacles, edges, texture, and elements such as handles or windows. Issues can arise if too little, too much, or non-uniform pressure is applied when installing the adhesive sheet material to variations in the surface or irregular surface features. These issues include gaps, air bubbles, or air-pockets in-between the surface and the adhesive sheet material and post application lifting of the adhesive sheet material from the surface caused by shrinkage of the adhesive sheet material after being overstretched. If the adhesive sheet material is not properly adhered to the surface, it can result in aesthetic problems, peeling off of the adhesive sheet material, and/or premature delamination from the adhesive sheet material causing future failure.
In order to aid in the smooth application of adhesive sheet material, it is desirable to use a lubricating liquid, such as a watery installation fluid, a soapy fluid, or any low viscosity liquid used for installations, in order to facilitate smooth application of hand force without undue friction that might warp the adhesive sheet material during application.
Currently, the art lacks a reliable and desirable apparatus and method for providing a continuous supply of a lubricating liquid to the adhesive sheet material as smoothing strokes are made to variations in the surface or irregular surface features, thereby applying the correct pressure, and preventing gaps, air bubbles, air-pockets, and lifting between the surface and the adhesive sheet material, while avoiding unwanted deformation of the adhesive sheet material.
Accordingly, there is a need for a device and a method to facilitate the provision of a continuous supply of a lubricating liquid to the adhesive sheet material as the adhesive sheet material is applied to the desired surface.
This application discloses improvements to those inventions disclosed and claimed in prior U.S. patent application Ser. No. 15/144,447, filed on May 2, 2016, now U.S. Pat. No. 9,975,319, which is a continuation of U.S. patent application Ser. No. 14/673,534, filed Mar. 30, 2015, now U.S. Pat. No. 9,327,480, which is a divisional application of U.S. patent application Ser. No. 14/294,137, filed Jun. 2, 2014, now U.S. Pat. No. 9,327,479, which claims the benefit of U.S. Provisional Application No. 61/956,067 filed Jun. 1, 2013, which applications are incorporated herein by reference in their entirety.
The present disclosure fills the need for a device and method that facilitates and addresses the shortcomings of the current devices for applying sections of adhesive sheet material to variations in the surface or irregular surface features and preventing gaps, air bubbles, air-pockets, and lifting between the surface and the adhesive sheet material.
The present invention includes a “micro cell” squeegee that becomes ready for use when an installer grasps the uncovered edge and dips the cell covered edge in water, a watery installation fluid, a soapy fluid, or any low viscosity liquid used for installations, or sprays the cell covered edge with the water or fluid, and begins using the wet edge of the squeegee for the appropriate wet process installation.
Due to the relatively acute angles the squeegee at which it is maintained with respect to target surface during installation, gravity keeps applying the liquid, that has accumulated and is held internally in the cells, outward to the covered edge until it is depleted and needs to be replenished.
This process allows the installer to work much more efficiently than was previously practiced by installers where the installer would just wet the surface of the covered edge of the squeegee, that in turn would not permit the edge to stay moistened for long. With this new technology it will allow for longer runs of installation time creating more productivity for the installer. This process can be on flat straight areas or complex substrate areas. Complex areas are areas of a substrate including but not limited to angles, extreme curves, deep narrow groves, crevices, dwells, channels and narrow channels and/or protrusions. The micro cell installation squeegee allows the covered edge of the squeegee to hold liquid for a longer period of time due to the micro cells filling with the liquid, holding it and allowing the covered edge to absorb the liquid as needed and stay wet for an extended period of time which can enhance the glide of the edge over normal temperature and/or heated adhesive articles preventing the edge to grip, wrinkle, deform or tear the various pressure activated and pressure sensitive adhesive articles.
According to one aspect of the present disclosure, an adhesive sheet material application squeegee is disclosed.
In some embodiments, the present invention includes an adhesive sheet material application squeegee for applying a liquid to a surface, comprising: (a) a gripping portion; (b) a flexible blade portion extending from the gripping portion, the flexible blade portion having a lateral surface comprising a series of voids or apertures adapted to receive a liquid, and having an application edge; and (c) an absorbent cover portion having interior and exterior surfaces and secured over at least a portion of the application edge, whereby the voids or apertures are adapted to receive a liquid from the interior surface upon oversaturation of the absorbent cover portion, and to contain that liquid, and whereby the voids or apertures are adapted to release that liquid to the absorbent cover portion as liquid is dispensed from the exterior surface.
