DESCRIPTION OF THE PREFERRED EMBODIMENTS

(8) Referring now to the drawings and the illustrative embodiments depicted therein, a rear slider window assembly 10 of a vehicle 12 (such as a pickup truck or the like) includes a window frame 14, a fixed window panel 15 comprising a pair of spaced apart side fixed window panels or panel portions 16, 18 (which may be separate panels or part of a single panel 15 with an aperture 17) and a movable window panel 20 that is movable relative to frame 14 and fixed window panels 16, 18 between an opened position and a closed position. In the illustrated embodiment, window assembly 10 includes two side fixed window panels or portions 16, 18 that are spaced apart with an aperture or opening or gap 17 therebetween and with upper and lower appliques 22, 24 spanning the gap at the upper and lower regions, respectively, of the window.

(9) The system or method or machine of the present invention provides a means for automatically (and optionally robotically) applying a masking strip to each of the upper and lower appliques of the window at the same time, which provides enhanced masking of the window and a reduction in manual labor to mask the window. The present invention provides a tape apply station with a table or support structure that holds and supports a window assembly (comprising the side fixed window panels and upper and lower appliques and frame). The applicator is movably mounted at the support structure and is linearly movable along the support structure and along and over at least a portion of the window assembly (that is secured at the support structure). The system or method provides an automatic film applicator, which may be installed on a robot or on a single axis drive system or the like.

(10) The applicator is operable to apply a thin one sided film to the applique locations on the rear slider window. The applicator uses a roll of tape that does not have a backing. The adhesive of the tape is rolled on itself and the machine or applicator applies the film and without wrinkles or air bubbles. The machine cuts the tape and rolls the tape out in one operation. The tape applied is Autowrap GL-931 White tape.

(11) As shown in FIGS. 3-15, the applicator machine comprises two separate applicators, each of which is operable to apply the film onto a respective applique as the machine moves the applicators over and along the appliques of the window. Each applicator comprises a spindle or roll support that supports the roll of film or tape, multiple guide spindles or rollers that guide the film as it is unrolled from the roll and applied to the appliques. The applicator includes a cutting element that cuts the tape at the desired length (at the start of the masking pass and at the end of the masking pass) so that the tape as applied is the correct length to cover the respective applique (and optionally to overlap onto the fixed window panels at each end of the appliques).

(12) The spindles or guide rollers protrude laterally from a frame portion and may be adjustably mounted at the frame portion to adjust the tension on the film as it is unrolled and applied. The lower two spindles or rollers are movable so that they selectively engage the film at the applique during the application process.

(13) Thus, and as can be seen with reference to FIGS. 6-15, a window assembly is secured at the support structure (such as via support elements that laterally and longitudinally hold the window assembly to limit movement of the window assembly during the film application process), with vertical supports under the window assembly, particularly at and under the appliques (to limit downward deflection of the appliques during the application process). The applicator is initially disposed at one end of the support structure (FIG. 6) with both of the lower rollers raised to an upper position so that, as the applicator is moved over the window assembly toward the appliques (FIG. 7), the lower rollers do not contact the window assembly.

(14) When the applicator is positioned partially over the appliques, the forward lower roller is moved downward to press the film (with its adhesive side down) toward and against the applique (FIG. 8), while the cutting device cuts the film at its end and/or releases the film so that the free end of the film drops down onto the applique. The applicator is moved backward (toward its initial location) with the forward lower rolling along the film to press the free end onto the applique (FIGS. 9 and 10). The forward roller is then raised and the rearward lower roller is lowered to engage the film, and the applicator is moved forward along the window assembly with the rear lower roller rolling along the film to press the film onto the applique (FIG. 11). Because the forward lower roller has pressed the end region of the film against the applique, the film is attached at the applique such that forward movement of the applicator pulls at the film and the film is unrolled from the spindle and applied to the applique by the rear lower roller as the applicator moves along the window panel and appliques.

(15) When the applicator gets to where the film being applied is at the end of the applique (FIG. 12), the film is cut so that its end falls onto the applique (FIG. 13). The applicator continues moving forward so the rear lower roller presses the end of the film onto the applique (FIG. 14). Optionally, the cut end may be held while the roller moves toward the film and presses the film toward and against the applique such that the film is held in tension throughout the application process. The lower rollers are raised and the applicator returns to its initial position (FIG. 15). As shown in FIGS. 15 and 16, when the applicator has finished, the film strips are pressed onto and adhered to the appliques with minimal bubbling or detachment over the entire length of the applique. Although shown and described for only one side of the applicator (and for one applique), the other side of the applicator functions in an identical manner and in tandem with the applicator to apply its strip of film to the other applique.

(16) The applicator is programmed for a particular window assembly, such as by entering dimensions and locations into its processor so that the applicator lowers the rollers and cuts the film at the appropriate locations along the window assembly and support structure. Optionally, the applicator may be adjustable in width to adapt the applicator for different window assemblies so that the strips of film being applied are at a desired or selected distance apart to be applied to the appliques of the particular window disposed at the support structure. Also, and such as can be seen with reference to FIG. 5, the side applicators may be angled so that the rollers are parallel to the surface of the appliques of the particular window assembly. The angles of the side applicators and rollers may be adjusted for the particular window assembly and may be dynamically adjusted during the application process to account for the contour of the outer surfaces of the appliques. The applicator thus may be programmed and adjusted or set to apply the strips of film for any window application, and thus may move the rollers and film over the particular shape and contour of the appliques. Optionally, the applicator may be used to apply a film or mask onto other window assemblies or panels for a vehicle, while remaining within the spirit and scope of the present invention.

(17) Thus, the present invention provides a method for masking a rear slider window assembly. The rear slider window assembly includes a movable window that is moved along rails between an opened and closed position relative to a fixed window panels and aperture or opening (such as by utilizing aspects of the window assemblies described in U.S. Pat. Nos. 8,402,695; 8,322,073; 7,838,115; 7,332,225; 7,073,293; 7,003,916; 6,846,039; 6,691,464; 6,319,344; 6,068,719 and 5,853,895, and/or U.S. Pub. No. Nos. US-2013/0174488; US-US-2011-0056140; US-2006/0107600; US-2008/0127563; US-2004/0020131 and/or US-2003/0213179, which are all hereby incorporated herein by reference in their entireties).

(18) Changes and modifications to the specifically described embodiments may be carried out without departing from the principles of the present invention, which is intended to be limited only by the scope of the appended claims, as interpreted according to the principles of patent law.
