ABSTRACT:
Angle measuring apparatus, particularly for measuring doctor blade angle, comprises an elongate support (1); a horizontal level detecting device (4) pivotally connected to an upper surface of the support (1); and means (5, 8) for determining the angle between the support (1) and the horizontal level detecting device (4). An under surface of the support (1) includes a pair of projecting feet (13, 14), the arrangement being such that when the apparatus is placed on a cylinder, the upper surface of the support (1) is substantially parallel with a chord of the cylinder.
