Abstract

The improved geared take-up roller assembly 1 for single strike ribbon, shown in the figure, provides for more positive take-up of the ribbon 2 and thereby reduces slippage during take-up of the initial portion of the ribbon 2. The geared take-up roller assembly 1 has a geared take- up spool 4 and a spiked driver 6. The spikes 8 of the spiked driver 6 are so contoured as to completely penetrate the ribbon 2 and to fit into the troughs 10 in the take-up spool 4. The spikes 8 and the troughs 10 are spaced apart by the same lineal distance (i.e., r0-1 = R0-2). During initial take up of the ribbon 2, a first spike on the spiked driver 6 will penetrate the ribbon 2 and force the ribbon 2 into a first trough against the leading trough shoulder.

Geared Take-Up Roller for Ribbon Spooling

The improved geared take-up roller assembly 1 for single strike ribbon, shown in the figure, provides for more positive take-up of the ribbon 2 and thereby reduces slippage during take-up of the initial portion of the ribbon 2. The geared take-up roller assembly 1 has a geared take- up spool 4 and a spiked driver 6. The spikes 8 of the spiked driver 6 are so contoured as to completely penetrate the ribbon 2 and to fit into the troughs 10 in the take-up spool 4. The spikes 8 and the troughs 10 are spaced apart by the same lineal distance (i.e., r0-1 = R0- 2). During initial take up of the ribbon 2, a first spike on the spiked driver 6 will penetrate the ribbon 2 and force the ribbon 2 into a first trough against the leading trough shoulder. A second spike on the spike driver 6 will next penetrate the ribbon 2 forcing the ribbon into a second trough and against a second leading shoulder. In this manner ribbon 2 will be taken up by the take-up spool 4 with a minimum of slippage.
