Claims

[Scope of utility model registration request]

A needle shaft and a needle guide shaft extending along the rotation center axis of the needle barrel are rotatably supported on the needle barrel, a needle lever is attached to the needle shaft on the side opposite to the needle guide shaft, and a needle lever is attached to the needle shaft on the side opposite to the needle guide shaft. A needle receiver lever is attached to the needle receiver shaft on the opposite side, and the needle lever is provided with a prick that protrudes and retracts from the circumferential surface of the needle barrel when the needle shaft rotates, and when the needle retracts, the needle receiver shaft The needle receiver lever is provided with a needle receiver member that protrudes from the circumferential surface of the needle barrel and receives an adjacent needle of an adjacent barrel adjacent to the needle barrel and presses the signature against the circumferential surface of the adjacent barrel when rotated;
a needle shaft lever is located on one end surface of the needle barrel and coupled to one end of the needle shaft; a needle receiver shaft lever is located on one end surface of the needle barrel and coupled to one end of the needle receiver shaft; The needle shaft lever and the needle shaft lever are connected by a link that transmits the rotation of the needle shaft to the needle shaft in the same direction, a cam follower is provided on the needle shaft lever, and the needle shaft lever is provided with a cam follower, and the direction in which the needle shaft member is retracted. A needle bearing shaft spring member for rotationally biasing the needle bearing shaft is provided on the needle bearing shaft, and the needle bearing shaft comes into contact with the needle shaft cam follower during the rotational phase of the needle barrel for pricking the signature with the adjacent pricking needles, and the needle a cam that rotates the shaft against the biasing force of the needle shaft spring member and rotates the needle receiver shaft via the link to retract the pricking needle and at the same time causes the needle receiver member to protrude and move; A needle guide device for a folding machine, characterized by comprising:
