Abstract
A bending-resistant gripper carriage support structure for offset printing machines is constructed of at least one hollow profiled member. In particular, one arrangement includes two hollow profiled members being connected by the bearing blocks of the gripper shaft for mounting the gripper carriage in the printing machine. A further arrangement includes the use of a single hollow profiled member for the gripper carriage support with an internally disposed web structure for subdividing the single profiled member.
Claims14
A bending-resistant gripper carriage arrangement for offset printing machines which, in order to increase the area moment of inertia and provide a high bending resistance, comprises at least one one-piece closed unperforated hollow profile member, a gripper shaft supported by said profile member, and gripping brackets carried by said gripper shaft for movement between a sheet gripping and a sheet releasing position, said profiled member being hollow throughout its length and having a continuous, smooth, curved, upper, outer sheet receiving surface extending for the entire length of the profiled member and wherein said gripping brackets grip a sheet between said brackets and said upper outer sheet receiving surface of the profile member in said sheet gripping position.
