Abstract
A covering sheet for applying to a selected surface in substantially fitted, covering relation consists of a flexible sheet of predetermined size and thickness, having a rectangular grid of lines to provide rectilinear yield lines (lines of weakness) extending in a first direction and in a second direction at right angles to the first direction, to enable tearing by hand along selected ones to the grid lines as a tear in a first direction, the sheet having individual perforations extending completely through its thickness, and located at the points of intersection of the axes of the lines of weakness. The perforations facilitate changes in the direction of a tear at a selected point of intersection, to extend the tear in the second direction, to achieve a desired size of sheet. The lines of weakness may further include tear lines extending diagonally between perforations, to facilitate changes in the direction of tearing, and to provide relieved corners to better fit into locations such as the corners of drawers, enclosed shelves, etc. The covering sheet may have an adhesive layer, such as a pressure sensitive adhesive on its reverse surface, and with the perforations extending also through the adhesive layer and through a release medium covering one face of the sheet. The perforations may comprise a reticulated series of through-cut microperforations arranged in oriented relation with the edges of the sheet. The release medium may be a removable sheet on the reverse face, covering the adhesive layer, or it may be applied in covering relation with the obverse face of the sheet when the covering sheet is supplied in rolled, self-wound form, usually upon a cardboard cylinder.
