Abstract (en)

[origin: EP0690162A2] A continuous material (9) is needle punched by taking it over several needle rollers (1) which rotate with their axes (3) perpendicular to the material path. The material (9) covers part of the circumference of the needle rollers (1) and their speed relative to the material is set to obtain the required needling effect with adjustable longitudinal stretch. Also claimed is the arrangement where the needle rollers (1) rotate about their axes (3) and the axes (3) move along a circular path. <IMAGE>
