LOADING A TAPE LOOP
A tape loop requires the same loading procedure as normal
punched tape. The following suggestions permit loading a
tape loop with a minimum of effort.
1. The tape loop should be long enough to feed freely
around the tape guides without dragging on the guide
edges. However , it should not be long enough to drag
on the floor.
2. The loop should also be very clearly marked for:
a. Starting position of the loop.
b. The direction of tape movement as it is read.
