<p>An improved method for forming holes (24) in a board (10) and an improved apparatus for practicing the improved method. Two or three linear arrays of holes (24) are punched through the board (10), through its expansive faces (12;14), in a punching zone (z3). A punch (334) and a die (274) coacting with the punch (334) are used to punch each punched hole, in a press (50) comprising a pressing ram (54) and a pressing bed (52), upon relative movement of the pressing ram (54) and the pressing bed (52) toward each other. The board (10) is registered in the pressing zone (z3), in a predetermined position, by engaging its opposite edges (16,18) and its opposite ends (20,22). Plural holes (28) are drilled into each end (20,22) of the board (10) in a drilling zone (z4). A physical measurement is conducted in an inspecting zone (z5), by inserting a probe (592,602) into each drilled hole (28), so as to determine whether such drilled (28) hole has been drilled to a minimum depth. These punching, drilling, and inspecting steps of the improved method are carried out in a series of automated operations of the improved apparatus. <IMAGE></p> |
