DETAILED DESCRIPTION

[0014] Turning now to the Figures wherein like numbers refer to like structures, FIG. 1 is a detailed schematic side view representation of one embodiment of the preformed water shields 10 arranged in stack 12. The water shield 10 has a foam or plastic or other formable body portion 14, into which is formed an inwardly angled channel 6 of sufficient depth 18 and sufficient width 20 to accommodate a glue bead 22 of sufficient amount to form a secure attachment to a substrate, such as a door panel as will be described in reference to FIG. 4. The glue may be any suitable glue, including but not limited to foamed or non-foamed hot melt adhesive. Looking briefly at FIG. 2, the channel 6 is formed in this embodiment by a vacuum molding process where the body portion is placed over a mold 32 and a vacuum and heat applied thereto to cause the body portion to deform into the channel shape as depicted. The shape of channel 6 includes angles and , which can be the same or different. Generally, angles and may be about 40 to about 75. It is contemplated that the angles can be outside of that range, so so long as the shape of channel 6 formed by angles and accommodates the glue and minimizes or prevents slippage of one stacked channel into the adjacent channel. Because of the angling of the walls of channel 6, the channels 6 have wider and substantially planar bases extending between the vertexes of the angled walls than the width of the openings to prevent slippage in stacked arrangements. Angles and may each have a rounded vertex rather than a sharp vertex, due at least in part to the material comprising the water shield 10.

[0015] In the depicted embodiment, the body portion has a thickness of about 4 mm, and the channel is drawn into the vacuum mold such that the channel has a depth of about 7 mm. The channel has a width (in this case 12 mm) that is sized and shaped to accept the glue bead 22, which in this case is shown as 6 mm, with a clearance of about 1 mm on each side of the glue bead 22.

[0016] It is important to note that any depth or width of the channel may be formed in any suitable thickness of material, provided that the glue bead 22 that is used does not extend to the wet or water-facing surface 24 of the water shield. It is also to be understood that although the channels 6 are depicted as having angled walls of at a particular angle, it is contemplated as seen in FIG. 3 that the sides 26 and 28 of the channel 6 could form a die lock 30 configuration as a result of the vacuum molding process. That is, the die lock 30 may be used to form angled walls within the meaning of the appended claims.

[0017] As it is apparent that the glue bead 22 does not extend to the wet surface 24 of the water shield 10, the water shields 10 may be stacked one on the other as seen in FIG. 1 without the need for a protective release sheet interposed between stacked water shields 10 to protect the glue from contact with the next sheet of water shield 10. The elimination of this release sheet eliminates labor, waste and costs associated with the sheet.

[0018] Additionally, as seen in FIG. 4, the wet surface 24 is placed in contact with the door panel 31 and the channel is deformed to press the glue bead into contact with the door panel thereby securing the water shield in place. The deformation into a V-shape creates a witness line. If the deformation is consistent along the length of the channel, adherence is confirmed. If there are gaps in the V-shape where the base of the channel remains substantially planar, a defect in adherence can be identified and addressed. Whatever procedure to adopted for placing the water shield 10 onto the door panel, it can be appreciated that the water shield 10 may be placed onto the door panel in an easy, accurate and reproducible way.

[0019] With regard to the processes described, it should be understood that, although the steps of such processes have been described as occurring in a certain sequence, such processes could be practiced with the described steps performed in a different order. It should be understood that certain steps could be performed simultaneously, that other steps could be added, or that certain steps could be omitted.

Many embodiments and applications other than the examples provided would be apparent upon reading the above description. The scope of the invention should be determined with reference to the appended claims along with the full scope of equivalents. It is anticipated that future developments will occur, and that the disclosed devices and processes used with such future developments. That is, the invention is capable of variation.
