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 the other end surface of the needle barrel and coupled to one end of the needle receiver shaft; A needle shaft cam follower is provided on the needle shaft lever, a needle shaft cam follower is provided on the needle shaft lever, and a needle shaft spring member is provided on the needle shaft for rotationally biasing the needle shaft in a direction in which the pricking needle protrudes. , a needle receiver shaft spring member is provided on the needle receiver shaft to rotationally bias the needle receiver shaft in a direction in which the needle receiver member protrudes; A needle shaft cam is provided which contacts the needle shaft cam follower and rotates the needle shaft against the biasing force of the needle shaft spring member to retract the needle, and the needle shaft cam contacts the needle shaft cam follower. Only during the rotational phase of the needle barrel in contact with the needle receiver shaft, the needle receiver shaft is brought into a non-contact state with the cam follower, and the needle receiver shaft is rotated by the biasing force of the needle receiver shaft spring member, thereby causing the needle receiver member to move in a protruding manner. A needle receiver device for a folding machine, characterized in that it is equipped with a cam for a needle guide shaft.
