Abstract:
1. A step flashing bending device for bending blank metal sheets into step flashing, the device comprising: a frame; a lower press block comprising an elongate working surface supported on the frame to extend in a longitudinal direction at a downward inclination from a top end to a bottom end of the lower press block; and an upper press block comprising an elongate working surface supported on the frame to extend in a longitudinal direction at a downward inclination from a top end to a bottom end of the upper press block so as to be substantially parallel to the working surface of the lower press block; the upper and lower press blocks being supported on the frame for movement relative to one another between an open position in which the working surfaces are spaced apart from one another so as to receive a blank metal sheet therebetween and a working position in which the working surfaces are displaced towards one another relative to the open position; the working surfaces being suitably shaped such that the blank metal sheet is arranged to be bent into a step flashing in the working position; and the frame comprising a bottom opening between working surfaces of the upper and lower press blocks at the bottom ends thereof such that the working surfaces are arranged to release the step flashing from the frame between the bottom ends of the upper and lower press blocks when the press blocks are displaced into the open position.
