    • A reliable method of aligning a printing plate against a stop includes moving the printing plate and the stop relative to each other, detecting temperature changes occurring at a temperature sensor connected to the stop, when the printing plate comes into contact with the stop, deriving signals indicating the position of the printing plate relative to the stop from the signals of the temperature sensor, and deriving a signal indicating the thermal conductivity between the printing plate and the stop from a speed of change of the temperature sensor signal. A signal indicating incorrect alignment of the printing plate against the stop is output if the thermal conductivity drops below a predetermined threshold.
    • 将印版抵靠挡块对准的可靠方法包括相对于彼此移动印版和挡板,检测当连接到挡块的温度传感器上发生的温度变化,当印版与挡块接触时,导出信号 从温度传感器的信号指示印版相对于停止的位置,并且从温度传感器信号的变化速度导出指示印版和停止之间的热导率的信号。 如果导热率低于预定阈值,则输出指示印版抵抗停止的不正确对准的信号。

    • A system and method for adhering and aligning a generally flat, planar object to an adhesive layer, and for facilitating the mounting of the generally flat planar object, such as a printing plate, in near perfect alignment in a cylindrical manner. The method includes providing a generally flat, planar object such as a printing plate and an adhesive member having an adhesive layer at least on one surface. The adhesive member is preferably approximately the same size as the printing plate. The printing plate is mounted to the adhesive member such that there is one edge of the adhesive member which is not initially covered by the printing plate and one edge of the printing plate which overhangs the adhesive member. The combined adhesive member/printing plate structure is next rolled into a cylindrical form and held in place on a device which allows alignment marks on the printing plate to align the two ends of the printing plate prior to the printing plate being fully adhered to the adhesive member. The resulting sleeve structure can then be inserted onto a plate cylinder and this assembly utilized in a printing press. In another embodiment, the adhesive member is provided as a single or multi-layered structure pre-rolled into a generally circular form.
    • 用于将大致平坦的平面物体粘附并对准粘合剂层并且用于便于以圆柱形方式几乎完美对准的基本上平坦的平面物体(例如印刷版)的安装的系统和方法。 所述方法包括提供大致平坦的平面物体,例如印刷板和至少在一个表面上具有粘合剂层的粘合剂构件。 粘合剂优选地与印刷版大致相同的尺寸。 印刷版被安装到粘合剂构件上,使得粘合剂构件的一个边缘最初不被印刷板覆盖,印刷板的一个边缘突出于粘合剂构件。 组合的粘合剂/印版结构接下来被卷成圆柱形并保持在一个装置上的位置,该装置允许印版上的对准标记在印版完全粘附到粘合剂之前对准印版的两端 会员。 然后将所得到的套筒结构插入印版滚筒,并将该组件用于印刷机中。 在另一个实施方案中,粘合剂构件被提供为预成形为大致圆形形式的单层或多层结构。

    • A plate holding apparatus includes a plate holding device and an air cylinder. The plate holding device holds an old plate discharged from a plate cylinder. The air cylinder moves the plate holding device between the first position of holding the discharged old plate and the second position away from the plate cylinder. The plate holding device includes a support member, first and second rotary members, a lever, stopper, and tensile coil spring, and a one-way clutch. The first rotary member is rotatably, axially supported by the support member. The second rotary member is axially supported by the support member to be movable and rotatable. The lever, stopper, and tensile coil spring move the second rotary member to come into contact with and separate from the first rotary member. When the old plate is held by the first and second rotary members, the one-way clutch allows at least one of the first and second rotary members to rotate in the first direction to disengage the old plate from the plate cylinder, and regulates it from rotating in the second direction opposite to the first direction.
    • 板保持装置包括板保持装置和气缸。 板保持装置保持从印版滚筒排出的旧印版。 气缸将板保持装置移动在保持排出的旧板的第一位置和远离印版滚筒的第二位置之间。 板保持装置包括支撑构件,第一和第二旋转构件,杆,止动件和拉伸螺旋弹簧以及单向离合器。 第一旋转构件由支撑构件可旋转地轴向支撑。 第二旋转构件由支撑构件轴向支撑以可移动和可旋转。 杆,止动器和拉伸螺旋弹簧移动第二旋转构件以与第一旋转构件接触并与第一旋转构件分离。 当旧板由第一和第二旋转构件保持时,单向离合器允许第一和第二旋转构件中的至少一个沿第一方向旋转,以使旧板与印版滚筒脱离,并将其从 沿与第一方向相反的第二方向旋转。
