Abstract

On forme une bande (12) de ressorts (14) hélicoïdaux ensachés en insérant des ressorts comprimés entre les couches supérieure et inférieure d'un tissu (16) replié, ce tissu étant de préférence thermosoudable. Les ressorts sont maintenus en position comprimée pendant l'assemblage des bords du tissu (16) thermosoudable au moyen d'une ligne (54) de soudure longitudinale. Ensuite on libère les ressorts (16) comprimés qui retrouvent leur position d'extension, puis on forme une ligne (80) de soudure transversale dans le tissu (16), entre les ressorts (14) adjacents, de sorte à encapsuler chaque ressort (14) dans une poche (86) de tissu. Ce procédé permet de former aisément une bande (12) de ressorts (14) hélicoïdaux ensachés sans qu'il soit nécessaire de réorienter les ressorts (14) après les avoir insérés entre les couches (24, 26) de tissu (16), ce qui permet d'éviter les inconvénients et les complications accompagnant le retournement et la réorientation des ressorts (14) hélicoïdaux ensachés.
