    Abstract: A lockup device for securing cutting mats to a rotary anvil comprises a base portion, one sidewall, and a wedge portion, and is adapted to be inserted into the channel of the rotary anvil such that the sidewall of the lockup device is adjacent a wall of the channel. A cutting mat having opposing first and second flanged ends is wrapped around the rotary anvil. The first flange is compressed between the locking wedge and the sidewall of the lockup device. The second flange is compressed between the locking wedge and a channel wall. As such, the locking wedge and cutting mat are frictionally secured to the rotary anvil. Further, the cutting mat may be quickly repositioned by releasing the second flange from the channel. When the cutting mat is unwrapped from the rotary anvil, the lockup device remains secured to the first flange, allowing for quick repositioning.

  • Patent number: 6691615
    Abstract: A printing plate is only guided by and wound around peripheral surfaces of cylinders. The cylinders are disposed along an axis of a rotating shaft at predetermined intervals, and support the entire printing plate with substantially equal balance. The printing plate has a degree of firmness, and thus, the printing plate can hold itself in a substantially cylindrical shape even if it is merely rolled in the air. Therefore, the whole printing plate can be accurately wound and held onto a peripheral locus of a predetermined radius coaxial with the rotating shaft merely by disposing guide members as auxiliary guides for positioning and winding parts of the printing plate.

  • Patent number: 6598378
    Abstract: A quick release mechanism for a roller (6, 7) wherein the roller (6, 7) is mounted in a frame and rotationally driven (for example, a roller (6, 7) carrying a roll of stretch wrapping film (4) in a stretch wrapping head (1)). The quick release mechanism includes a pair of stub axles (22, 43) which support either end of the roller (6, 7) in the frame. One of the stub axles (22) are fixed within the frame and driven by a motor (8). The connection between this driven stub axle (22) and the roller (6, 7) ensures that no relative rotational movement occurs. The other stub axle (43) is “lockable” in a hole in the frame but is removable therefrom. The connection between the removable stub axle (43) and the roller (6, 7) allows free relative rotational movement. Withdrawal of the removable stub axle (43) from the frame allows the roller (6, 7) to be disconnected from its connection with the driven stub axle (22) and removed from the frame.
