Abstract

See full text

A method of making a nonwoven from continuous filaments is provided. The method comprises the steps of spinning continuous filaments from a spinneret to move along a vertical travel path in a vertical travel direction, cooling and stretching the filaments downstream of the spinneret in a cooler and a stretcher, and depositing the cooled and stretched filaments at a deposition location on a foraminous belt moving horizontally underneath the cooler and stretcher and having an array of openings of which a portion are plugged with a sealing compound to create a partially plugged foraminous belt. The method comprises drawing air downward through unplugged openings in the foraminous belt to stabilize the continuous filaments deposited on the foraminous belt, and pre-consolidating the deposited nonwoven into final form.
