The present invention relates to a chain of elastic bands (1), comprising at least two elastic bands (3), wherein adjacent elastic bands are joined to one another by means of at least one bridging piece (4). The longitudinal direction (A) of the elastic bands preferably extends transversely to the longitudinal direction (C) of the chain of elastic bands (1). The chain of elastic bands can have been produced from a flat, sheet-like web of elastic material (9), such as rubber, preferably natural rubber, in which essentially oval elastic bands (3) have been formed. The elastic bands have a constant width (B) all round. Adjacent elastic bands are preferably joined to one another by at least two bridging pieces (4), which are preferably each arranged at a transition between the adjacent longitudinal strips (5) and arc-shaped strips (6). The chain of elastic bands according to the invention can be rolled up into a roll or can be folded up to form a harmonica-like stack. Chains of elastic bands of this type can be produced, for example, from rubber which is still in the unvulcanised state or from an elastic plastic.

Chapelet d'élastiques (1) comportant au moins deux élastiques (3), les élastiques voisins étant reliés entre eux par au moins une pièce de liaison (4). De préférence, le sens longitudinal (A) des élastiques est transversal au sens longitudinal (C) du chapelet d'élastiques (1). Le chapelet d'élastiques est éventuellement produit à partir d'une bande plate en matière élastique en forme de feuille (9), par exemple en caoutchouc et de préférence en caoutchouc naturel, dans laquelle sont formés des élastiques (3) essentiellement ovales. Les élastiques présentent une largeur constante (B) sur toute leur longueur. De préférence, les élastiques voisins sont reliés entre eux par au moins deux pièces de liaison (4) formées de préférence dans la zone de transition entre les segments rectilignes (5) et arqués (6) contigus. Ledit chapelet d'élastiques peut être enroulé ou plié de manière à former un empilage en accordéon. On peut produire les chapelets d'élastiques de ce type, par exemple, à partir de caoutchouc non encore vulcanisé ou d'une matière plastique élastique.
