(57) The invention relates to formwork for supporting an arched head over a window or
door opening. The formwork (8) includes a front horizontal portion (10), a front upright
portion (11), an upper arched portion (12) and a rear vertical portion (13 or 23).
At each end of the formwork the upper arched portion (12) merges into a horizontal
extension (14). In one embodiment of the invention (Figures 1 and 2) the upper arched
portion (12) interconnects the arcuate upper edges of the front vertical portion (11)
and the rear vertical portion (13). In another embodiment of the invention (Figures
3 and 4) the rear vertical portion (23) has a straight upper edge (21), the height
of which is greater than the maximum height of the front vertical portion.
