Abstract
A method of making tennis bracelets includes coupling together collet elements (2) in a repetitive series, wherein an L-shaped lateral appendage (3) of a collet element is inserted into a through hole (6) of an immediately adjacent collet element and then bent against a face (7) of the collet element to which it belongs. The collet elements are inserted according to the repetitive series into an assembly template (10) implemented as a self-supporting unit provided with fasteners (16) for fastening the unit to first and second carriage supports (22, 36) of first and second machines (18, 19), which cause the assembly template to translate under a die block (26) of a press device (24) of the first machine. The lateral appendages (3) of the collet elements are bent in succession under a laser welding head (38) of the second machine, for welding the appendages (3) to their respective collet elements.
