摘要： The printing head is of the type in which the tips of the needles are guided in two parallel rows by a pair of matrices (7, 8) disposed side by side and carried, a first by a support fixed to the printing body and a second by a support movable on the printing body so as to move the second matrix parallel to the first from a position in which the tips of the needles in the two rows are at the same heights (high-speed printing) to one in which the tips of the needles in one row are located at the heights of the spaces between the tips of the needles in the other row (high-definition printing); the movable support is fixed to the printing body by a parallelogram structure in which two parallel sides are constituted by the support (12) and the body (2) and the other two sides by resiliently-deformable members (20, 21); pre-loaded, resilient biasing means (200) keep the movable support against a first abutment (22) and an electromagnetic actuator (23), when operated, moves the movable support into contact with a second abutment (24).

摘要： The head has twenty four pins (11) each welded to the edge (56) of a blade (44) placed in a radial plane. Each blade (44) is rigidly attached to the keeper (41) of a corresponding electromagnet (25), which is placed in a plane perpendicular to that of the corresponding blade The edge (56) is supported by an appendage which can have two different forms (53 and 54) so that the edges (56) of successive blades (44) are radially offset so reducing the distance between these edges and the axis (16) of the head. Blades (44) normally rest against an elastomeric ring (63), the position of which can be adjusted along axis (16).
