Methods for manufacturing fiber-cement soffits with air vents

A method of fabricating a fiber-cement soffit, comprising:

• providing a cured fiber-cement panel having a thickness, and the fiber-cement panel comprising cement, cellulose material, and a binder;
• placing the fiber-cement panel between a punch assembly and a support assembly, the punch assembly having a punch plate and a plurality of punches coupled to the punch plate, and the support assembly having a support plate with a plurality of holes;
• driving the punches through at least a portion of the thickness of the fiber-cement panel to form apertures in the fiber-cement panel by ejecting plugs from the fiber-cement panel through the holes in the support plate;
• withdrawing the punches from the fiber-cement panel without delaminating the fiber-cement panel at the apertures;
• and
• wherein the fiber-cement panel has a thickness of approximately 0.25-0.31625 inch, and wherein driving the punches comprises penetrating the punches into the panel to a depth of approximately 0.0625-0.1875 inch without passing the punches completely through the panel and thereby producing a ventilated fiber-cement soffit.

A method of fabricating a fiber-cement soffit, comprising:

• providing a cured fiber-cement panel having a thickness of approximately 0.25-0.625 inch;
• placing the fiber-cement panel between a punch assembly and a support assembly so that a first side of the panel faces the punch assembly and a second side of the panel faces the support assembly, the punch assembly having a punch plate and a plurality of punches coupled to the punch plate, and the support assembly having a support plate with a plurality of holes;
• and
• driving the punches through only a portion of the thickness of the fiber-cement panel to form a plurality of tapered openings in the fiber-cement panel and thereby producing a ventilated fiber-cement soffit.

A method of fabricating fiber-cement soffit, comprising:

• providing a cured fiber-cement panel having a length, a width, and a thickness, wherein the thickness is approximately 0.25-0.625 inch;
• placing the fiber-cement panel between a punch assembly and a support assembly so that a first side of the panel faces the punch assembly and a second side of the panel faces the support assembly, the punch assembly having a punch plate and a plurality of punches having a first cross-sectional dimension coupled to the punch plate, and the support assembly having a support plate with a plurality of holes having a second cross-sectional dimension larger than the first cross-sectional dimension of the punches;
• driving the punches along a punch stroke through at least a portion of the thickness of the fiber-cement panel to form a plurality of openings in the fiber-cement panel that have the first dimension of the punches at the first side of the panel and the second dimension of the holes at the second side of the panel;
• and
• pressing a compressible biasing element against the first side of the fiber-cement panel as the punches move along the punch stroke and thereby producing a ventilated fiber-cement soffit.
