<p>The present invention relates to the stretching of canvas or other flexible materials (such as printed photographs, artwork, illustrations, gallery wrap) on a stretching frame to be displayed without the use of a conventional picture frame. This invention is designed to be sold as a kit which can be assembled by an unskilled end user without the use of stretching pliers and staplers (which require considerable strength and skill). The present invention allows for the tucking of the corner folds of canvas inside the mitered corners for a neater result than then the standard stretching systems available today. The finished product will have no side edge fasteners, unsightly corner folds or wrinkles. Tension is added to the finished product by means of corner tensioners which are snug-fit into corresponding grooves in the stretcher bars.</p> |
