It is known a contiguous strip of device, which the expanded leaves of the to be made mechanically from pieces of tobacco leaf, cut lengthwise into strips, are present, one after the other with a weak overlap is characterized in that according to the invention be attached to each other. If this overlap is done by testing devices to detect holes or missing hands, there is a risk that the transfer points in the parenchyma, length measuring devices for the coverage is too big. In any case, it has to be tailored to strips and sheeters to form large, if one assumes half-leaves, the longitudinal sections of the individual strips, the have borrowed tips. If, on the other hand, the sheets are controlled by the testing and measuring devices, and Before being freed from their tips, the price of devices for connecting to short strips increases Applying this way of working. IO sections are more sufficient to form stripes

On the other hand, tobacco leaves themselves show good lengths are provided.

Quality sometimes cracks or holes, which are worth their value. Another device was known to

reduce. According to previous methods, the production of sections of the desired length A contiguous strip can be made as it would appear from an art binder, i. H. a paper tape, mechanically, are not used, provided that 15 and that in a cigar wrapping machine as a result it has cracks. It is therefore necessary to measure that two conveying frames lying one on top of the other for cutting and restoring the roll, one of which has a recess, contiguous strip with which are thereby provided. The feed devices can do this take substantial excess coverage. for the leaf rib from an endless conveyor

In this case, however, a certain negative pressure can be maintained, holes or tears in the tobacco leaves cannot be opened and the walls with air admission can still be taken into account. The same also applies to a 30 opening, which in the vicinity of the previously known machine for the simultaneous removal axis of the rib a larger and in the ripping and cutting of the cover and cover sheets stood from the axis a smaller cross-section than tobacco leaves with a cutting roller, which are seated, the air inlet openings being appropriately distributed apart from the ring-shaped knives known per se for the spreading device via a substantially three-cut out of the ribs as matrices or male molds 35 angular surface, the tip of which is directed against the formed profile knife for punching out the surrounding inlet opening .

The cover sheets are lifted off the conveyor belts 25 by suction devices (not shown), which come into effect in a position which is determined by the length of the cover sheets. Movable Cover disks 36, which are arranged in the suction line, interrupt the suction of the Cover sheet at the moment when it is lifted by the suction device.

The final suckers then go to mechanical winding devices known per se.

In this way, one conveyor belt 25 can supply several suction devices.

So especially those with platelets provided chain 3 can be replaced by a conveyor belt with a rounded cross-section; the rotating mirror 15 through contact combs; the cross cutters 16 by filament or spark gap cutting means; the strips can be cut perpendicular to the conveying direction instead of at an angle; the The rest position of the contact tips 21 can be the outer position instead of the pushed-in position; the tester for the presence of tobacco on the drum 9, a contact instrument with a Be a grinding comb that grinds on the metallic drum that forms the mass, while the comb with a weak power is fed from an oscillating circuit that supplies a voltage that is sufficient, in order to avoid disadvantages caused by the contacts, but loses its charge in the event of defects and also gives the signal for the presence of tobacco; the photoelectric pulse system for the Length measurement of the tobacco can also be a contact device, for example in the manner of a distributor.
