Abstract (en)
A wrapper feed control system includes a feed mechanism 3,7 for feeding continuous wrapping material 1 to a separating station employing knives 4. A detector 5 scans the material to detect registration marks 2 and this information passes to computation unit 10 which also receives information from synchronising switch 9 and pulse generator 11 and from these determines any error in the registration mark position relative to the machine cycle. A variable correction is made via motor 6 to increment or decrement the feed dependent on the computed error.
