Abstract (en)
[origin: WO2020070591A1] Products like tennis bracelets are obtained by coupling together a plurality of collet elements (2) according to 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 said repetitive series into an assembly template (10) implemented as a self- supporting unit provided with fastening means (16) for fastening it 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, bending in succession the lateral appendages (3) of the collet elements, and under a laser welding head (38) of the second machine, for welding the appendages (3) to their respective collet elements.
