ABSTRACT:
A position detector senses an undulating pile tuft edge position of a carpet as it is processed in a carpet making machine by detecting attenuated light passing through the carpet's primary backing material to determine the exact position of the carpet's undulating pile tuft edge at any given time. Sensor signals from the detector are digitally filtered through one pole cascaded filters to produce an average pile edge position signal which, in turn, controls actuators for secondary and primary backing material guide rolls to not only center the carpet for aligned entry into the carpet machine's tenter, but also apply the secondary backing material to the primary backing material at a precise position.
