Abstract: A mechanism for clamping a flexible metal printing plate to the circumferential surface of a rotatable plotter drum is provided. The clamping mechanism includes a mounting member affixed to the drum's surface. The mounting member has a passage aligned radially with respect to the drum. A slidable member extends through the passage and past the drum's axis of rotation. The slidable member has, at one end, a head and, at the other end, a weight. The clamp head is disposed further from the axis of rotation than the mounting member and adjacent the drum surface so as to permit clamping between the head and the drum surface. The slidable member is disposed so that its center of mass is opposite the drum's axis of rotation from the head. A mechanism, such as a compressed spring mounted between the weight and the mounting member, is provided for urging the slidable member so as to force the head towards the drum surface. An actuator having two modes is also provided. In the first mode, it forces the slidable member so as to move the head away from the drum surface and, in its second mode, it permits the head to be urged towards the drum surface by the urging means. The clamping mechanism is also provided with a mechanism for turning the slidable member, so that every time the actuator goes into the second mode the clamp head is turned 90 DEG from the previous time the actuator went into the second mode.

Abstract: A rotatable drum for use in a plotter, or similar device, that provides vacuum for holding the film or other media to the drum's surface, so as to easily accommodate films of various sizes. The drum includes first and second journals (10) and a plate (7) mounted on the circumference of the first and second journals. At least one of the journals has defined on its circumference circumferential channels. The plate (7) has interior and exterior sides, and the first and second journals and a portion of the plate's interior side define a chamber (3). The plate's exterior side has defined thereon a plurality of grooves (72). In one embodiment, at least one of the grooves, associated with a first film size, is in fluid communication with the chamber (3), and some of the remaining grooves, associated with the larger film sizes, are in fluid communication with the channels. A vacuum is supplied to the chamber, and a valve (50) is provided for controlling fluid communication between the channels and the chamber.
