Abstract
An apparatus for processing short lengthed, elongate waste timber workpieces to usable timber beams of relatively long length includes a cutter device for cutting wedge-shaped tenons into the ends of the elongate workpieces, a gluing device for applying a thin coating of glue to the cut tenons on each end of each workpiece, and a press device for pressing the workpieces together such that the cut tenon ends of each workpiece is glued to the cut tenon ends of another workpiece to form a timber beam. A length-cutting device can be used to cut the timber beam into the appropriate lengths as desired.
Claims20
An apparatus for processing short lengthed, elongate waste timber workpieces into usable timber beams of relatively long length which comprises
- (1) a cutter means for cutting tenons into each of the elongate ends of each of the waste timber workpieces, said cutter means comprising a vertically movable machine table, an abutment plate mounted on said machine table and extending upwardly away therefrom, and two spaced apart cutter blades mounted on a common shaft and positioned adjacent to said abutment plate, such that when two waste timber workpieces are placed, respectively, at the intersection point between said machine table and one side surface of said abutment plate and the intersection point between said machine table and the other side surface of said abutment plate, and said machine table moved vertically, said two cutter blades may respectively cut tenons into the adjacent ends of the two workpieces;
- (2) a gluing means positioned adjacent to said cutter means for supplying a thin film of glue to the cut tenons on each end of each of the waste timber workpieces cut by said cutter means;
- and
- (3) a press means positioned adjacent to said gluing means for progressively pressing the glue-coated cut tenons of each end of each of the waste timber workpieces treated by said gluing means into a glue-coated cut tenon of another waste timber workpiece so as to allow gluing of the workpieces together to form a timber beam of relatively long length.
A method for processing short lengthed, elongate waste timber workpieces into usable timber beams of relatively long length which comprises
- (a) placing waste timber workpieces in pairs on a movable table of a tenon-cutting machine;
- (b) clamping the workpieces in place on said movable table;
- (c) cutting tenons in one of the ends of each of the pair of timber workpieces;
- (d) rotating the pair of timber workpieces on the movable table;
- (e) cutting tenons in the other of the ends of each of the pair of timber workpieces;
- (f) placing the pair of cut timber workpieces on the fixed table of a gluing device such that one of the ends of each of the pair of workpieces is placed against a glue-coated comb;
- (g) moving the combs past said pair of workpieces to apply a thin coating of glue on said contacting tenon-cut ends;
- (h) rotating said pair of workpieces on said fixed table so that the other of the ends of each of the pair of timber workpieces is placed against a glue-coated comb;
- (i) moving the combs past said pair of workpieces to apply a thin coating of glue on said contacting tenon-cut ends;
- (j) pressing together the glue-coated tenon-cut ends of said pair of workpieces to form a timber beam;
- (k) sequentially pressing a further glue-coated tenon-cut end of additional waste timber workpiece to an exposed glue-coated tenon-cut end of the timber beam of (j) to produce a longer timber beam;
- and
- (l) cutting the longer timber beam of (k) to the desired length using a cutting device.
