Title Device for backward needling of non-wovens.

The problem the inventor(s) wanted to solve

Elaboration of a device for backward needling of non-wovens.

Description.

The essence of the invention is a device with two needling beams situated opposite to one another. The beam needling pull out fibers from the neighboring pile layers and draw them in opposite directions. Such method of fiber movement causes their mutual entanglement, much stronger than in non-wovens needling traditionally with an influence on their tensile strength.
