FIELD: process engineering.
SUBSTANCE: invention relates to removal of red-pulp from mineral fibres. Proposed method comprises making of the web of mineral fibres containing said red-pulp and untangling of web fibres. Untangling comprises feed of said web to at least one roller running about its lengthwise axis and has sharp tenons extending from roller peripheral surface. The roller outermost points run at velocity of 15-200 m/s.
EFFECT: higher efficiency of red-pulp removal.
