Toolmakers probably used pressure flaking by 100,000 years ago in East Africa, remarks paleoanthropologist John Shea of Stony Brook University in New York.
Shea, an expert at making replicas of Stone Age tools, notes that pressure flaking can be taught in 30 minutes to a novice.
Any practical advantages that pressure flaking offered to weapon-toting hunters remain unclear, in his opinion.
The Cereal Master TX includes a flaking roll in its standard configuration for making wheat and bran flakes using the traditional steam cooking process.
A standard Cereal Master EX line producing extruded cereals such as corn balls, multigrain rings, alphabet shapes, and cocoa balls can be extended, through additional units (including the flaking roll) and Baker Perkins' process expertise, to make a range of flakes, multigrain flakes and filled pillows.
* Kimberley dentate points, which are invasively pressure flaked biface points, where the 'teeth' formed by pressure flaking on the margins are separated by notches wider than their teeth (Akerman et al.
1995; Allen 1997) is the use of pressure flaking (ie the use of an indentor to remove flakes from an artefact) in their manufacture.
Across the world, many plants are in operation with sound building structures but obsolete flaking
lines that have ceased to satisfy the requirements.

The lumber was cut into 2- by 6- by 14-inch samples for disc flaking and 1- by 1.5-by 4-inch samples for ring flaking.
For CCA boards, wood treatment reduced MOR and MOE properties especially for ring flakes; however, both flaking type and wood treatment did not affect the IB strength of all PMDI panels.
