Abstract
Glazing panels, such as window panes, are protected by sheets of masking material which cover central regions of the panel surfaces and which leave marginal regions uncovered. The masked panels are installed in frames which can thereafter be sanded or painted or otherwise chemically treated. Prior to and during such treatments, the surfaces of the panels are protected by the masking material. After all installation and treatment procedures are complete, the masking material is removed to expose the clean central regions of the panel surfaces.
Claims4
A method of making a glazing assembly, the method comprising:
- initially applying a sheet of masking material on a first surface of an uninstalled glazing pane that (a) has first and second surfaces each of which has a central region and a perimeter region surrounding the central region and (b) that is sized and shaped to be installed in a frame, the masking material being sized, shaped and positioned to cover at least portions of both the central region and the perimeter region of the first surface;
- and
- then removing portions of the sheet that cover the perimeter region, to leave uncovered at least a portion of the perimeter region of the first surface, the width of the uncovered portion being not less than the distance the first surface will extend along a facing surface of the frame when the pane is installed.
A method of making a glazing assembly, the method comprising:
- initially applying a sheet of masking material on a first surface of an uninstalled glazing pane that (a) has first and second surfaces each of which has a central region and a perimeter region surrounding the central region and (b) that is sized and shaped to be installed in a frame, the masking material being sized, shaped, and positioned to cover all but two side margins of the first surface, which side margins are portions of the perimeter region;
- and
- then removing those portions of the sheet that cover two end margins of the surface to leave the end margins uncovered, which end margins are portions of the perimeter region of the first surface, the width of each uncovered end margin being not less than the distance the first surface will extend along a facing surface of the frame when the pane is installed.
A method for making glazing assemblies, the method comprising:
- moving a plurality of uninstalled glazing panes, edge-to-edge, along a path, the panes being sized and shaped to be received by frames;
- adhering a continuous web of a masking material to coplanar surfaces of the panes as the panes move along the path;
- cutting the web at locations positioned such that the panes can be separated after the web is adhered;
- and
- removing edge regions of the web so as to uncover end margins of each surface, the width of each end margin being not less than the distance the end margin will extend along a facing surface of a frame when the pane is installed in the frame.
