Abstract
Each of a plurality of nested templates are attached concentric to one another in spaced apart relationship to a common sheet of material to define a plurality of concentric bands on the surface of the sheet. The sheet is cut away coincident with each band by a router or the like guided by adjacent templates edges to leave closed frames corresponding in size to the attached template and ready for finishing upon detachment of the template.
Claims13
Apparatus for defining cuts to be made to obtain one piece frames from sheet material, said apparatus comprising in combination:
- (a) a plurality of concentric templates, each said template locating the interior and exterior perimeters and width of a one piece frame;
- and
- (b) means for securing each said template to the sheet material concentric with an adjacent one of said templates and spaced apart therefrom;
- whereby, said adjacent spaced apart templates define continuous bands of sheet material to be cut to obtain the one piece frames.
A method for cutting one piece frames from sheet material, said method comprising the steps of:
- (a) locating each of a plurality of concentric templates upon the sheet material to define the interior and exterior perimeters and width of a frame;
- (b) securing each of said templates to the sheet material;
- (c) positioning a cutting tool intermediate and guided by the edges of adjacent spaced apart templates;
- and
- (d) cutting the sheet material to form frames comporting with the templates.
Apparatus for cutting one piece frames from sheet material, said apparatus comprising in combination:
- (a) a plurality of concentric templates for locating the interior and exterior perimeters and width of each of the one piece frames;
- (b) means for securing each said template to the sheet material generally concentric with an adjacent one of said templates and spaced apart therefrom;
- (c) means for cutting the sheet material to form the one piece frames in conformance with said templates;
- and
- (d) means for positioning said cutting means intermediate and guided by the edges of adjacent spaced apart ones of said templates;
- whereby, said adjacent spaced apart templates define continuous bands of sheet material to be cut to obtain the one piece frames.
