The embodiments described herein are generally directed to graphics, such as numbers, letters, licensed characters, figures, and other images, that are applied to garments and other textiles.
Graphics, such as letters, numbers, licensed characters, figures, and other images are commonly applied to garments and other textiles. Many different techniques exist for applying such graphics, including screen printing, heat transfer, stitching, etc. Each available technique gives the graphic a somewhat different appearance. For example, when a graphic is stitched onto a garment or textile, the stitch marks are visible to an observer. For various applications, this “stitched” appearance is desirable. However, stitching graphics onto a textile is more costly and time consuming than other methods of applying graphics, such as adhering the graphic to the textile using a heat-activated adhesive, for example.
The inventors hereof have recognized a need to provide a graphic that has a “stitched” appearance, but is faster and more cost-effective to apply to a textile than actually stitching the graphic to the textile.
The embodiments described herein relate to a graphic and related methods for generating and applying such graphic to a textile having a “stitched” appearance, but which does not involve actually stitching the graphic to the textile. A cutting device, such as but not limited to a laser, is used to cut the graphic from a material. The cutting device is further used to create “scallops” around the perimeter of the graphic such that a series of small projections of material extends outward from the perimeter of the graphic to emulate the appearance of the stitching thread that would normally be present outside the perimeter of the graphic if the graphic were actually stitched to the textile. The cutting device is further used to “etch” a pattern into the graphic itself, near the graphic's perimeter, to emulate the stitching thread that would normally be present on the interior of the graphic if the graphic were actually stitched to the textile. The graphic is then applied to the textile using a method other than stitching, such as adhesion using a heat-activated adhesive on the backing of the graphic. In this way, the desired “stitched” appearance is achieved at a lower cost.
As best shown in
One possible laser system that can be used to cut the graphic 5 (including the projections 12) and to create the etched pattern 14 in the material of the graphic 5 to simulate a stitched appearance is described below, with reference to
The laser beam 112 is deflected by the y-axis mirror 117 and directed through a focusing lens 119. The lens 119 is adapted to focus the laser beam 112. The lens 119 is a multi-element flat-field focusing lens assembly, which optically maintains the focused spot on a flat plane as the laser beam moves across the material 11 to generate the graphic 30. The apparatus 110 further includes a working surface 120 which can be almost any solid substrate such as a table, or even a gaseous fluidized bed. The material 11 is placed on the working surface 120. The working surface 120 can be adjusted vertically to adjust the distance from the lens 119 to the grain 16 of the material 11.
