Method and machine for producing a muselet for bottles of effervescent drinks

Machine intended for manufacturing Y-shaped muselets for bottles of effervescent drinks, comprising:

• means for twisting of one end of a first wire over an overlap region situated approximately in a middle of a second wire, the wires forming part of a same first plane and being oriented therein so as to form an approximate first right angle between a non-twisted end of the first wire and one of free ends of the second wire, and to form a second angle of approximately 135° between the free ends of the second wire;
• pneumatic cylinders for forming a first loop at each free end of the first and second wires, in said first plane, and for forming a second loop in a plane substantially perpendicular to the first plane, by folding, said cylinders being able to actuate two parallel spindles rotating with respect to each other and motors with a horizontal or vertical axis depending on an orientation of the loops to be formed;
• a template comprising a cap serving as a support substantially in said first plane, and three peripheral shoes for folding wire legs by pressing for folding the three wires at a certain distance from said an overlap region for twisting, in a plane substantially perpendicular to said first plane;
• means for connecting a rim formed by a third wire by simultaneous passage of the third wire through the three second loops of a cage formed from the first and second wires for cooperating with the rim by translation in a direction substantially perpendicular to said first plane, and means for closing the three second loops by pressing their second free ends in a direction parallel to said first plane.
