The base (1) enables alternatingly associating various crochet-bearing groups to a sewing machine (M). The base (1) comprises a column bearing structure (10), fixed on a support table (100) and designed to support at a top thereof a head (T) of the sewing machine (M), in predetermined longitudinal positions, The bearing structure (10) houses an electric motor (E) for activating the machine (M) and the corresponding crochet-bearing group (PC), via transmission organs, The bearing structure (10) internally comprises upper coupling means (3), to which a relative crochet-bearing group (PC) identified in a first series (31, 32, 33) is associable, and lower coupling means (4), to which a relative crochet-bearing group (PC) identified in a second series (41, 42, 43, 44) is associable. |
