• the device (1) comprising at least one support body (6) provided with:
• a mounting portion (50) configured for allowing the device to be mounted to the at least one supporting structure of the circular knitting machine;
• a front side (10) directed towards and directly facing said at least one component-holding unit of the knitting machine, the front side (10) being provided with at least one cam (11) for controlling at least a part of said plurality of stitch formation components (2), said at least one cam (11) defining a guiding path (12) configured for interacting with respective butts (3) for controlling each of the stitch formation components (2) of said at least a part of said plurality of stitch formation components;
• a rear side (20), opposed to said front side (10) and facing the outside of the knitting machine, away from said at least one component-holding unit;
• wherein said front side (10) is without undercuts or holes or hollow surfaces facing said component-holding unit;
• and wherein the device (1) comprises a left side face (40) and a right side face (41), which are transversal to and structurally connect said front side (10) and said rear side (20), and wherein the left side face (40) and the right side face (41) are arranged on opposite sides with respect to said guiding path (12) of the at least one cam (11), and wherein the device comprises a top side face and a bottom side face;
• and wherein said at least one cam (11) is defined on a cam body (70), removably mountable to the at least one support body (6) of the device (1), so that the guiding path (12) is defined on said front side (10), and wherein said cam body (70) comprises a front portion (71) on which said guiding path (12) is defined, and a fastening portion (72) placed laterally to said front portion (71) and provided with fastening members for fastening the cam body (70) to said left side face (40) or said right side face (41) of the at least one support body (6) of the device (1), wherein said fastening members comprise at least one through hole (74) in said fastening portion (72) and at least one fastening screw (75);
• and wherein said at least one cam (11) comprises a plurality of cams (11) defined on a corresponding plurality of cam bodies (70) mounted to the at least one support body (6) of the device (1), so that the respective front portions (71) of the cam bodies (70) lie on the front side (10) of the device (1) and the respective fastening portions (72) of the cam bodies (70) are fastened to said left side face (40) or said right side face (41) of the at least one support body (6) of the device (1).
