ABSTRACT:
A method of making feedstock from material supplied in rolls of flexible sheet material which comprises the steps of creating a pluri-layer web of "n" different layers of sheet material, each layer being selected with regard to some known parameter property of the sheet material whereby the pluri-layer web has an aggregate value of the selected parameter which lies within a chosen range of values of said parameter property. Conveniently the feedstock is created by disintegrating the pluri-layer web to create a mass of comminuted pieces of sheet material.
