The invention relates to a system, with which a chain (2), consisting of a series of closed links, can be formed from a chain extension (2'), consisting of a series of open links, wherein said chain extension (2'') is fed into abutment with and along a perihperal surface part (3b) of a rotatable disc (3), and sections of said chain extension rest against the disc at a first radius (R1), wherein said chain extension is caused by roation of the disc to pass through a link-welding and/or link-soldering unit (31), in which said open links are closed to form closed links of the chain (2). More particularly, the invention comprises: a) displacing said open links to a slightly more compact state, upstream of said link-welding and/or link-soldering unit (B, 31); b) closing the slightly compacted open links, according to a) above, to form closed links in said unit (B, 31); and c) displacing (C) said closed links to a more compacted state, downstream of said link-welding and/or link-soldering unit (B, 31). |
