Filed: 1982-04-02
Abstract: In the production of wrappers or binders of different sizes from tobacco leaves, these leaves are at first divided into strip pieces that are transferred to a conveyor section and by means of a scanner are scanned to ascertain usable areas with preference from the largest to the smallest size.
