A method for forming a sheet of loop material in which a sheet of fibers (12) is passed between a first cylindrical forming member (18) having sockets (21) and a second cylindrical forming member (19) having mating posts (24) to generally conform the sheet of fibers to the peripheral surface of the first forming member and retain it there for a distance after which a backing layer (16) is attached to it. Arcuate portions (14) of the sheet of fibers that were in the sockets (21) then projecting from the backing layer (16). The formed sheet of fibers is retained along the peripheral surface of the first forming member for said distance by drawing air through those air passageways (22) in the bottoms of the sockets (21). The first forming member (18) can be heated, and a source of heated air (39) can be supplied to restrict cooling of the first forming member. The backing layer can be of breathable film to make the sheet of loop material breathable.

Procédé servant à fabriquer une feuille de matériau à boucle et consistant à faire passer une plaque de fibres (12) entre un premier élément de formage cylindrique (18) possédant des matrices (21) et un deuxième élément de formage cylindrique (19) possédant des protubérances appariées (24), de manière à adapter la plaque de fibres à la surface périphérique du premier élément de formage et à retenir ladite plaque sur ledit élément sur une certaine distance, après laquelle on lui fixe une couche de renforcement (16). Des parties incurvées (14) de la plaque de fibres qui se trouvaient dans les matrices (21), forment alors une saillie depuis la couche de renforcement (16). La plaque de fibres obtenue est retenue le long de la surface périphérique du premier élément de formage sur ladite distance en aspirant de l'air par des passages d'air (22) situés dans les parties inférieures des matrices (21). On peut réchauffer le premier élément de formage (18) et on peut effectuer l'apport d'une source d'air réchauffé (39) afin de limiter le refroidissement du premier élément de formage. La couche de renforcement peut être constituée par un feuil permettant la respiration, de façon à rendre la feuille de matériau à boucles capable de respirer.
