    • A method and apparatus of securing and tensioning a printing form in an apparatus having a rotatable drum includes securing a first portion of the printing form to a first means for receiving that is coupled to a surface of the drum, and securing a second portion of the printing form to a second means for receiving that is disposed on a rotatable member that extends over a portion of the drum. The rotatable member is rotated so that the circumferential distance between the first receiving means and the second receiving means is about the same as a length of the printing form. A rotary torque means is coupled to the rotatable member to apply a substantially constant torque on the member and tension the printing form about the surface of the drum. The rotary torque means adjusts torque on the member which adjusts tension on the printing form.
    • 一种在具有可旋转滚筒的设备中固定和张紧打印形式的方法和装置,包括将印刷形式的第一部分固定到第一接合装置,该第一装置联接到滚筒的表面,并固定第二部分的 印刷形式设置在第二装置上,该第二装置设置在可旋转的构件上,该旋转构件在滚筒的一部分上延伸。 可旋转构件旋转,使得第一接收装置和第二接收装置之间的周向距离与打印形式的长度大致相同。 旋转扭矩装置联接到可旋转构件,以将基本上恒定的扭矩施加在构件上并且将张力沿鼓的表面张紧。 旋转扭矩装置调节调节打印纸张张力的构件上的扭矩。
