<p>Methods and apparatuses for producing fiber-cement soffit building products. In one embodiment of the invention, an apparatus for producing fiber-cement soffits includes a punch assembly (40), a support assembly (60) facing at least a portion of the punch assembly (40), and an actuator (70) operatively coupled to at least one of the punch assembly (40) or the support assembly (60). The punch assembly (40) can include a punch plate (42) and a plurality of punches (50) coupled to the punch plate (42). Each punch (50) can have a length and a first cross-sectional dimension generally normal to the length. The support assembly (60) can have a support plate (62), and at least a portion of the support plate (62) is juxtaposed to at least a portion of the punch plate (42). The support plate (62) can include a plurality of holes (6 4) arranged in a pattern so that each hole (64) in the portion of the support plate (62) juxtaposed to the punch plate (42) is aligned with a correspondin g punch (50) on the punch plate (42). Each hole (64) can have a second cross- sectional dimension greater than the first cross-sectional dimension of the punches (50) to define a radial punch/hole clearance between each punch (50) and each hole (64). The radial punch/hole clearance, for example, is general ly greater thanthat of metal punch presses to allow the punches (50) to be removed from a fiber-cement panel (14) without delaminating portions of the panel (14).</p> |
