Abstract
In a single facer having split blades for stripping a corrugated medium from one of the corrugating rolls and then guiding the corrugated medium to a pressure nip where a liner is applied thereto, the blade sections are biased toward the corrugating medium by a single spring which acts through blade holding cranks so constructed that retracting the upstream blade section against the force of the biasing spring automatically retracts the downstream blade section against the force of the biasing spring thereby minimizing interference between the downstream blade section and a thickened web portion.
