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. The strip pieces cut out of the same halves of tobacco leaves (right and left sides) are advanced on a further conveyor section consisting of separate, parallel belts, from which strip pieces of equally large, usable areas are collected in the same bobbin, in which they are oriented parallel to the axis of the bobbin and with their usable areas aligned in the longitudinal direction of the bobbin web. The cutting of nondefective final wrappers or binders is subsequently carried out in a separate operation and without further sorting. This provides for obtaining an optimum output from the tobacco leaves by using an apparatus of non-complicated design.

Abstract: In a wrapper rolling machine for the manufacture of cigars etc. and comprising a wrapper cutting out unit, means are provided to hold one half of a tobacco leaf while cutting is performed in its other half, and to deliver the first half, together with any scraps appending thereto, in a plane condition and a desired orientation for the subsequent cutting out of one or more wrappers from said first half.
