Abstract: A modular vise system for holding working objects having a bottom surface, the modular vise system includes a fixture plate and an adjustable vise member configured to secure the working object to the fixture plate. The adjustable vise member includes an elongated body forming a cavity; a flange extending from a side of the elongated body, the flange having an elongated hole extending through a thickness of the flange; a fastener configured to engage with and extend through the elongated hole, the fastener and elongated hole allowing the body to selectively translate relative to the fixture plate; a moveable assembly housed at least partially disposed within the cavity of the body and configured to selectively translate relative to the body; and a gripper coupled to the moveable assembly and configured to secure to the working object.

Abstract: Adjusting the height of a gripping device above the surface of a fixture by providing a separate riser between the gripping device and the working surface of a fixture. The risers can be stacked as needed to raise the gripping device to an elevation to effectively grip the workpiece. The guide in the riser blocks for the gripping devices will direct the gripping device in a central predetermined position of the part to be machined or welded, thus saving time on the unclamping and clamping of the parts resulting in a great cost saving of time and labor. Additionally, risers of different sizes can be more easily manufactured than the gripping device itself.

Abstract: A printing plate includes, on the printing surface of a raised part, grooves passing through from one side to another thereof. Preferably, the grooves are parallel to each other and equally spaced apart. More preferably the raised part is in the shape of a nearly-rectangular frame, and the grooves are provided such that one side of the near-rectangle and the longitudinal direction of the grooves form an angle of 45°.

Abstract: A printing group of a rotary printing press includes at least one forme cylinder and at least one transfer cylinder. The forme cylinder has at least two printing forme end receiving channels. These two channels are spaced circumferentially. At least one of these forme cylinder end receiving channels rolls off against a channel in the transfer cylinder. One of the forme cylinder end receiving channels is at least partially covered by a printing forme carried by the forme cylinder.
