摘要: A roller for use in fibrillating oriented films of polyolefin materials having a plurality pins projecting from the surface roller. The are distributed rows spaced around surface. each contain about 25 to 34 per inch space-staggered relationship along two adjacent lines extending roller, either linear inclined line parallel axis or rotation, sinusoidal with being out phase. is rotated and film advanced over rotating an arc length contact 30 37 degrees fibrillate film. ratio speed advancing controlled between 1.8:1 2.2:1.
