Abstract
The machine automatically cuts out a section from a tobacco leaf to form a covering. Optical devices scan a blade to find an area free from holes, which is turned up and cut out to produce the covering. A T.V. camera with detector frames can be used, a number of lines parallel to the leaf stem being detected in each frame and the resulting video signal being compared with a datum signal. Two binary signals are generated, dependent on whether the datum signal is the greater or lesser. This is used in a logic system to produce a signal giving the position of holes along the lines.
