Abstract
A double-sided adhesive-coated foam tape particularly for bonding two adjacent rigid surfaces in which fine grooves on one or both sides of the tape facilitate air venting to minimize non-contact areas. The tape is used by affixing one side of the tape--the non-grooved side if only one side of the tape is grooved--to a first rigid surface to be adhered, removing the release liner from the grooved tape surface and pressing onto the grooved tape the second rigid surface intended for bonding. The grooves in the tape are fine enough that, once the two surfaces to be bonded are in position, the grooves largely or completely disappear.
