Abstract
A method of forming a building panel is provided, with the building panel including facer and liner sheets surrounding a foam core. The method includes the steps of pre-notching the facer sheet at each false joint, roll forming the side joints of the facer sheet, bending the facer sheet, via a press operation, at the pre-notched area to form the false joint, such that the facer sheet is a continuous sheet across the false joint, and bonding the facer sheet having the false joint and the liner sheet to the foam core to form the building panel.
Claims15
A method of forming a building panel including facer and liner sheets surrounding a core material comprising the steps of:
- pre-notching a facer sheet at a false joint;
- roll forming side joints of the facer sheet;
- bending the facer sheet at the pre-notched area to form the false joint, wherein the facer sheet is a continuous sheet across the false joint;
- and
- bonding the facer sheet having the false joint and the liner sheet to a core material to form the building panel,
- wherein the false joint comprises a depression formed in the facer sheet, the depression comprising a base surface extending into the foam core and opposing side surfaces, and
- wherein the false joint comprises tabs provided one each on the opposing side surfaces at the pre-notched area, wherein the tabs are folded under one of the side joints of the facer sheet in the formation of the false joint.
A method of forming a building panel including facer and liner sheets surrounding a core material comprising the steps of:
- providing a facer sheet in the form of a coil of sheet material, the facer sheet having a length and opposed ends defining a width;
- pre-notching the facer sheet at the opposed ends at each false joint along the length of the facer sheet;
- pre-notching the facer sheet at the opposed ends at each real joint along the length of the facer sheet;
- roll forming the opposed ends of the facer sheet to form side joints;
- bending the facer sheet across the width of the facer sheet at the pre-notched areas to form the false joints, wherein the facer sheet is a continuous sheet across the false joints;
- cutting the facer sheet at each real joint to form a plurality of facer sheets;
- providing a liner sheet in the form of a coil of sheet material;
- bonding the plurality of facer sheets having false joints and the liner sheet to a core material to form building panels;
- and
- cutting the core material and liner sheet at each real joint of the facer sheets to form separate building panels,
- wherein the false joint comprises a depression formed in the facer sheet, the depression comprising a base surface extending into the foam core and opposing side surfaces, and
- wherein the false joint comprises a tab formed on each of the opposing side surfaces at one of the pre-notched areas at the false joint, wherein the tabs are folded under the side joint of the facer sheet in the formation of the false joints.
