Nonwoven fiber-sheet process |
摘要 |
A process is provided for reducing the size and number of undesirable gauge bands in wound-up rolls of wide nonwoven sheet that is produced by a plurality of oscillating fiber streams depositing fiber on a moving receiver. The desired effect is accomplished by varying the oscillation frequency of the fiber streams by more than +/-5% of the average oscillation frequency.
