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).

摘要： A dot-matrix print head (1) wherein a casing (2) houses a number of sliding print needles (3) arranged radially about a central axis (7), respective rocking members (4) associated with the needles (3), and respective electromagnets (5) for controlling the rocking members and for attracting the respective rocking members in opposition to elastic contrasting means (6) to move the respective rocking members selectively into a rest position and a print position; the elastic contrasting means (6) are defined by a substantially U-shaped monolithic annular element (6) made of elastomeric material and having two continuous circumferential projections (21, 22) spaced radially to rest, with respective predetermined loads, on respective first and second contact portions of the rocking members (4); and the annular element (6) is so shaped and sized that the ratio between the respective predetermined loads exerted by the projections (21, 22) on the respective first and second contact portions (23, 24) of the rocking members (4) ranges between roughly 7:1 and roughly 3:1 when the rocking members are in the rest position, and between roughly 3:1 and roughly 1:1 when the rocking members are in the print position.
摘要翻译：一种点阵打印头（1），其中壳体（2）容纳围绕中心轴线（7）径向布置的多个滑动打印针（3），与针（3）相关联的相应摇摆构件（4），以及相应的电磁铁（5），用于控制摆动件并用于吸引相对于弹性对比装置（6）的各个摆动件，以将各个摆动件选择性地移动到静止位置和打印位置; 弹性对比装置（6）由基本上U形的由弹性材料制成的单片环形元件（6）限定并具有径向间隔开的两个连续的周向突起（21,22），以分别在各自的第一和摇摆构件（4）的第二接触部分; 并且环形元件（6）的形状和尺寸被设计成使得由突起（21,22）施加在摇摆构件（4）的相应第一和第二接触部分（23,24）上的相应预定载荷之间的比率范围在摇摆构件处于静止位置时大约在7：1和大约3：1之间，当摇摆构件处于打印位置时大约在3：1和大致1：1之间。
