Abstract
The method for jointing frames, small pieces of furniture, drawers, with corner parts, is characterized by the successive operations: simultaneously cutting the sides of the frame to the desired dimensions; machining the halving of each corner part in a single operation into two adjacent elements of the frame to be assembled and simultaneously in the four corners; gluing the corner parts and their housing hollowed out in the elements to be assembled; the premounting of corner parts in their housings; the assembly and tightening of the frame thus formed. The corner parts used are flat with one or two ogival ends and/or one straight end and/or one whistle-shaped end forming a 90.degree. angle, and/or one bevelled end and/or one rounded end, and/or one circular end.
Claims16
A method for miter jointing a frame which has a plurality of sides to be joined to form corners, said method comprising:
- (a) cutting the sides of said frame;
- (b) machining a corner part to be inserted into each of said corners to be joined, and machining said frame sides to have recessed portions;
- (c) positioning said sides adjacent to each other so that recessed portions on respective sides will be positioned adjacent to each other to form a plurality of hollow corners;
- (d) premounting said corner parts within said hollow corners;
- (e) gluing said corner parts into said hollow corners;
- and
- (f) jointing and thereafter tightening said frame, wherein said frame sides are cut to desired dimensions in step (a) by simultaneously cutting two sides, thereafter machining said frame sides to form said hollow corners.
Apparatus for jointing frames having corners, said apparatus comprising:
- (a) a vertical pendular power saw having two circular blades angled at approximately 90.degree. to each other and comprising means for miter cutting sides of said frames;
- (b) a first template for positioning and retaining sides of said jointed frame in an assembled form;
- (c) means for machining hollow corner portions in two adjacent frame sides and means for machining a plurality of corner parts;
- (d) a station for gluing and pre-mounting said respective corner parts into hollow corners formed between adjacent frame sides;
- and
- (e) a movable template for mounting and framing sides of said frame.
