FIELD: textile, paper.
SUBSTANCE: mechanical fabric, such as an endless tape or sleeve for use in the manufacture of nonwoven materials, and a method of its manufacture are disclosed. The mechanical fabric is created by spirally winding stripes of polymeric material, such as a technical belt or tape material, and joining the adjacent sides of the material stripes using laser or ultrasonic welding. Then the fabric can then be perforated using a suitable method to make it permeable to air and/or water.
EFFECT: increased strength properties.
