PATENT `OFI-Ica CIGARETTE Wilhelm Ziehe, Berlin-Oberschcneweide, Germany, assignor of one-fourth to Paul Hochstetter and one-fourth to Emil Staub, both of Berlin, Germany, and one-fourth to Hugo Staub, Berlin-Charlottenburg, Germany Application January 3, 1934, Serial No. '105,129l

In Germany June 1, 1932 y 2 Claims.

My invention relates to cigarettes the wrappers of which do not consist of paper but of tobacco.

The primarybject of my invention consists in a cigarette with a tobacco wrapper which is stable, elastic and able to offer resistance to destructive forces. Other objects of my invention will become apparent from the following specification of my improved manufacturing method.

According to my invention the filling of the cigarette is wrapped with threads of tobacco which are spun from cut tobacco, and such threads may be wrapped directly about the fllling, or a fabric woven from the said tobacco threads may be used as wrapper of the cigarette.

In carrying out my improved method the tobacco leaves are longitudinally cut to long strips yof very small breadth which are spun to threads "like textile fibres. 0n account of the small tensile strength of the tobacco threads, the spinning is performed by well-known mechanisms used for working up fabrics of very little tensile strength.

The spinning process is favorably influenced by copiously moistening the longitudinally cut tobacco strips, before they are worked up. A moistening liquid of 50% of glycerine and 50% of water has been found very eflicient. For an equable moistening it is preferable to season the tobacco fibres in their moistened condition.

From the ready spun tobacco threads a fabric of tobacco may be woven which is wrapped about the filling of the cigarette, or the tobacco threads may be wound directly round the filling of the cigarette in the same well known way as textile threads are woven round the cablesfor conducting electricity.`

After having been 'provided with its tobacco (Cl. 13b-52) wrapper the cigarette may be pressed for flattening the same. By compressing the wrapper its sealing property is augmented.

It is already known to make cigarettes with wrappers of tobacco. But according to the known method wrappers are employed which consist of one single piece of a tobacco leaf. For this reason the cigarettes made according to the known method have not the good mechanical properties of an ordinary cigarette.

In the annexed drawing,

Figure 1 is a view of a cigarette made according to the invention, the wrapper consisting of threads coiled around the filler.

Figure 2 is an enlarged longitudinal section of a portion of the same.

Figure 3 is a view of a cigarette having a woven wrapper.

Figure 4 is an enlarged cross section of the cigarette shown in Figure 3.

In Figures 1 and 2, the numeral 1 designates the filler of the usual type,'and 2 designates the tobacco threads wrapped directly around the ller.

In Figures 3 and 4, 3 designates the usual filler and 4 designates the tobacco threads woven into a fabric whichis wrapped around the filler. In both forms, the cigarette is shown as before being subjected to compression.

I claim:

1. A cigarette comprising a flller, and a wrapper consisting of spun tobacco threads wrapped around the filler.

2. A cigarette comprising-a filler, and a wrapper consisting of tobacco threads woven together WILHELM ZIEHE.
