Abstract
The perforated strip is transported lengthwise along a predetermined transport path. The perforations have a width w and an inter-perforation spacing s as measured in the transport direction. The perforations are sensed at two predetermined sensing locations located along the transport path. The distance between the two sensing locations is equal to as .+-. bw, wherein a is equal to zero, unity or an integer greater than unity, and wherein b is a number greater than zero and less than unity. Sensing the perforations at sensing locations thusly spaced makes it possible to determine from the resultant signals the direction of strip transport.
