Abstract
The lineal crown mouldings of the present invention comprise an elongated moulding with a front surface having a top front chamfer portion, a bottom front chamfer portion and a front non-planar decorative profile portion positioned between said top front chamfer portion and said bottom front chamfer portion and a back surface having a top back chamfer portion and a bottom back chamfer portion and a back non-planar decorative profile portion positioned between said top back chamfer portion and said bottom chamfer portion. The front surface and the back surface have substantially identical configurations inverted relative to each other about a vertical centre line from a top edge of said crown moulding to a bottom edge of said crown moulding.

7. The lineal crown moulding according to claim 1 wherein when viewed in cross section, thin sections between the front non-planar decorative profile portion and back non-planar decorative profile portion have sufficient structural integrity and strength to be used in long lengths.
8. The lineal crown moulding according to claim 7 made from MDF
wherein the modulus of elasticity (MOE) and modulus of rupture (MOR) at the center of the crown moulding are optimized by one or more of the steps selected from the group consisting of increasing the amount of resin to fiber, utilizing more refined fiber or changing the press cycle.
wherein the modulus of elasticity (MOE) and modulus of rupture (MOR) at the center of the crown moulding are optimized by one or more of the steps selected from the group consisting of increasing the amount of resin to fiber, utilizing more refined fiber or changing the press cycle.
9. A lineal crown moulding comprising an elongated moulding with a front non-planar decorative profile and a back non-planar decorative profile portion wherein the lineal crown moulding has a uniform cross-section along its length, the cross section having an upper half and a lower half having substantially identical configurations reversed 180 degrees relative to each other about a horizontal centre line through a mid point of said cross section.
10. The lineal crown moulding according to claim 1 cut to form a pre-mitred corner wherein the same part forms an inside or outside corner.
11. A method of cutting lineal crown moulding comprising a front surface having a top side front chamfer portion, a bottom side front chamfer portion and a front non-planar decorative profile portion positioned between said top side front chamfer portion and said bottom side front chamfer portion and a back surface having a top side back chamfer portion and a bottom side back chamfer portion and a back non-planar decorative profile portion positioned between said top side back chamfer portion and said bottom side chamfer portion wherein said front surface and said back surface have substantially identical configurations inverted relative to each other about both a vertical centre line from a top side of said crown moulding to a bottom side of said crown moulding and horizontal centre line through a mid point of said front surface and said back surface to form mitred corners, using a mitre saw said method comprising the steps of:
(a) adjust the mitre saw to cut half of the angle of the corners;
(b) place the crown moulding with a top chamfer portion resting against a fence of the saw and a bottom chamfer portion resting against the table of the saw;
(c) cut to form a left side moulding and a right side moulding;
and (d) to create a mitred corner turn the right side moulding over and butt the cut ends of the left side moulding and a right side moulding together to form either an inside or outside corner with one cut.
(a) adjust the mitre saw to cut half of the angle of the corners;
(b) place the crown moulding with a top chamfer portion resting against a fence of the saw and a bottom chamfer portion resting against the table of the saw;
(c) cut to form a left side moulding and a right side moulding;
and (d) to create a mitred corner turn the right side moulding over and butt the cut ends of the left side moulding and a right side moulding together to form either an inside or outside corner with one cut.
12. A method of cutting a lineal crown moulding comprising a front surface having a top side front chamfer portion, a bottom side front chamfer portion and a front non-planar decorative profile portion positioned between said top side front chamfer portion and said bottom side front chamfer portion and a back surface having a top side back chamfer portion and a bottom side back chamfer portion and a back non-planar decorative profile portion positioned between said top side back chamfer portion and said bottom side chamfer portion wherein said front surface and said back surface have substantially identical configurations inverted relative to each other about both a vertical centre line from a top side of said crown moulding to a bottom side of said crown moulding and horizontal centre line through a mid point of said front surface and said back surface to form mitred corners, with a compound mitre saw said method comprising the steps of:
(a) adjust the mitre angle and bevel angle of the saw according to the crown moulding's spring angle and corner angle;
(b) place the crown moulding with either the front or back surface resting flat against the saw table;
(c) cut to form a left side moulding and a right side moulding;
and (d) to create a mitred corner turn the right side moulding over and butt the cut ends of the left side moulding and a right side moulding together to form either an inside or outside corner with one cut.
(a) adjust the mitre angle and bevel angle of the saw according to the crown moulding's spring angle and corner angle;
(b) place the crown moulding with either the front or back surface resting flat against the saw table;
(c) cut to form a left side moulding and a right side moulding;
and (d) to create a mitred corner turn the right side moulding over and butt the cut ends of the left side moulding and a right side moulding together to form either an inside or outside corner with one cut.
13. A method of installing lineal crown moulding comprising a front surface having a top side front chamfer portion, a bottom side front chamfer portion and a front non-planar decorative profile portion positioned between said top side front chamfer portion and said bottom side front chamfer portion and a back surface having a top side back chamfer portion and a bottom side back chamfer portion and a back non-planar decorative profile portion positioned between said top side back chamfer portion and said bottom side chamfer portion wherein said front surface and said back surface have substantially identical configurations inverted relative to each other about both a vertical centre line from a top side of said crown moulding to a bottom side of said crown moulding and horizontal centre line through a mid point of said front surface and said back surface, said method comprising the steps of:
