In an ink supply apparatus, inks of a paste-like consistency are supplied from a cylinder to a chamber doctor blade disposed adjacent an inking roller. Two conduits are disposed at opposite ends of the chamber doctor blade and each conduit communicates with one of the two opposite ends of the cylinder. Ink is supplied to the cylinder through an aperture. Within the cylinder there is disposed a reciprocating piston which, at low speed, forces ink via the conduits to the chamber doctor blade.

Apparatus for ink supply

An apparatus for folding an edge (11) of a continuous web (10) is disclosed, wherein the continuous web (10) is held against a belt (1) which is twisted through substantially 180.degree. between two wheels (2, 3) to fold over the edge (11) during the twisting action. The belt (1), which is endless, runs over two other wheels (4, 5) in order to return to the wheels (2, 3).
