摘要： A high speed media management device has tractor means for moving a web through the device past a plurality of work stations at each of which the web may be treated. Relatively high web tension is maintained throughout its travel path. Counting means near the beginning of the web path generate a count signal with the passage of each increment of web. The accumulated count signals are compared to numbers stored in a plurality of registers, each register associated with a work station and each containing a count representative of web travel distance relative to the work station. The first register count corresponds to the distance required to accelerate the web from a stop. The remaining registers store that count and a separate count representing the distance between the first station and the corresponding station. When the counter contents equals the count in a register, an actuating signal initiates a treatment activity at the associated work station. At predetermined intervals thereafter, additional actuating signals generated and applied.

摘要： A high speed web cutter has a rotating roller with an extended bar mounted perpendicular to its surface and angled to be aligned askew with respect to the roller's axis. During the rotation of the roller, the bar interferingly contacts a plate having an angled edge that is mounted on a relatively stiff cantilever spring. The bar edge and the plate edge are not mounted parallel with each other nor are either of them parallel with the plane of the web. As the roller rotates, the extended bar deflects the cantilever spring, allowing the edges to intersect in a cutting intersection that travels axially with roller rotation, thereby severing a web member passing between the roller and the plate edge.

摘要： A core/hub assembly for a printing device that provides for easy alignment and insertion, and maintains a secure interface to prevent slippage of the core during printer operation, is disclosed. A hub includes keys mounted at a proximal end which serve to transmit torque when engaged with a core. The hub further includes splines configured to be received within a core and provide longitudinal support thereto. A core includes a plurality of longitudinally extending ribs that cooperate to form channels configured to receive the splines of the hub. A portion of the ribs include compliant radially oriented leaf springs which center the core on the hub and provide a physical fit of the core on the hub by engaging the keys at the proximal end of the core when properly inserted therein.
