Abstract
Abstract Opposed rolls for manufacturing rolled products from powdery material are provided with lateral collars which shape the edges of the product being rolled and form a receptacle for the powdery material in which lateral forces are developed and applied to the product in the course of rolling. The space between the collars has a height between 0.1 and 0.9 times the average spacing between the rolls (average thickness of the product) and a width between 0.2 and 3 times the average spacing between the rolls.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
95 words
Apparatus for manufacturing rolled products from powdery materials, comprising: opposed shaped rolls including collars which shape the edges of the product being rolled, said rolls having spaced opposed surfaces which define the thickness of the rolled product, said collars defining a space therebetween having a height lying within 0.1 to 0.9 and a width lying within 0.2 to 3 of the spacing between said opposed surfaces of the rolls to form a receptacle for the powdery material, said collars constituting a means for developing lateral forces applied to said product in the course of rolling.
