Wire binding machine

A wire binding machine comprising:

• a wire guide track arrangement, by which a wire is guidable in one or more loops around a space configured for receiving one or more objects to be bound;
• a twisting device, which comprises a housing, a twisting head rotatably mounted in the housing so as to be rotatable in relation to the housing about an axis of rotation and a first electric motor for rotating the twisting head in relation to the housing, the twisting head being rotatable by the first electric motor to bind portions of said wire together by twisting to thereby secure the wire around said one or more objects, wherein the twisting head is provided with:
• a first wire guide channel that extends through the twisting head at a front end thereof,.
• a second wire guide channel that extends through the twisting head at the front end thereof,
• a first gripping member for gripping and locking a wire portion received in the first wire guide channel, and
• a second gripping member for gripping and locking a wire portion received in the second wire guide channel, wherein the first and second gripping members are individually moveable in the twisting head from a wire releasing position to a wire gripping position;
• and
• a feeding device for feeding the wire through the first wire guide channel in the twisting head, into the wire guide track arrangement, along the wire guide track arrangement around said space in one or more loops and into the second wire guide channel in the twisting head and subsequently retracting the wire to draw it tightly around one or more objects received in said space,
• wherein the twisting device comprises:
• a first drive member, which is non-rotatably fixed to the twisting head and which is configured to be rotated by the first electric motor in order to rotate the twisting head;
• a first transmission mechanism for transmitting torque from the first electric motor to the first drive member;
• a second drive member, which is rotatably mounted in the housing so as to be rotatable in relation to the housing about said axis of rotation, wherein the second drive member is rotatable in relation to the twisting head from a rotary starting position to a rotary end position;
• a second electric motor for rotating the second drive member in relation to the twisting head from said rotary starting position to said rotary end position;
• a second transmission mechanism for transmitting torque from the second electric motor to the second drive member;
• and
• a motion transferring mechanism, which is configured to transfer a rotary movement of the second drive member in relation to the twisting head from said rotary starting position to said rotary end position into sequential movements of the second gripping member and the first gripping member from its wire releasing position to its wire gripping position.
