摘要

Bands of cotton, glass, cellulose acetate, polyamide, polyester, acrylic or polyolefin staple fibres having a length of 6.5 to 140 mm are produced by removing a wide web directly from a carding drum by a pair of rollers whose axes are inclined at an angle of 70 to 89 degrees to the drum axis, imparting a constant tension to the fibrious web along its whole width and compacting the web into a band whose width is less than a third of the web and whose wt. may vary from 2.72 to 46.5 g/m2.
