ABSTRACT DOCTOR BLADES A composite doctor blade assembly includes a length of steel strip 21, forming the doctor blade, and a similar but narrower back-up blade 22. The strips 21, 22 are clamped between a resiliently flexible carrier strip 23 and an arched resilient strip 24 held together under tension by ties 25 passing through apertures 23a, 24a. To make the blade assembly longitudinally flexible, the apertures are elongated. The plate 23 is clamped in a holder between an intermediate element 11 and a bottom element 12 with the interposition of an inter- changeable cylindrical packing element 13. The top element 14 is channel shaped to provide extra rigidity.
