Abstract:
1. An apparatus for supporting a corrugated metal sheet, comprising: a lower frame; a lower vibration absorbing pad supported by the lower frame; an upper frame positioned above the lower frame and the lower vibration absorbing pad, the upper frame movable relative to the lower frame between an open position and a closed position, the upper frame adapted to receive a cutting tool; and an upper vibration absorbing pad secured to the upper frame such that the upper vibration absorbing pad is in a face-to-face relationship with the lower vibration absorbing pad, in the open position the lower and upper vibration absorbing pads are separated to permit the corrugated sheet metal to be positioned therebetween and in the closed position the corrugated metal sheet is clamped between the lower and upper vibration absorbing pads with at least one of the lower and upper vibration absorbing pads substantially conforming to the contour of an adjacent surface of the corrugated metal sheet, wherein the upper frame and the upper vibration absorbing pad each has a longitudinal slot for receiving the cutting tool, and wherein the lower vibration absorbing pad is harder than the upper vibration absorbing pad.
