Method and assembly for opening cigarette wrappers in a machine for recovering tobacco from defective and or substandard cigarettes

Method of opening a cigarette wrapper including cutting open the cigarette transported in a guiding groove of a feeder of a machine for recovering tobacco from defective and/or substandard cigarettes with at least one revolving disc knife located above the feeder, in which:

• the at least one revolving disc knife is applied to the cigarette in such a way that the axis of rotation on which the said disc knife is mounted slantwise in relation to the cigarette axis lies on a plane parallel to the plane over which the cigarette axis is translated;
• the possibility of rotation of the cigarette around its axis in the guiding groove is blocked;
• whereby variable tensile stress is applied in the cigarette wrapper facilitating its opening.

Method of opening a cigarette wrapper including cutting open the cigarette transported in a guiding groove of a feeder of a machine for recovering tobacco from defective and/or substandard cigarettes with at least one revolving disc knife located above the feeder, in which:

• the at least one revolving disc knife is applied to the cigarette in such a way that the axis of rotation on which the said disc knife is perpendicularly mounted lies on a plane parallel to the plane over which the cigarette axis is translated, the cigarette axis moving in the guiding groove along a sine curve;
• the possibility of rotation of the cigarette around its axis in the guiding groove is blocked;
• whereby variable tensile stress is applied in the cigarette wrapper facilitating its opening.

Method of opening a cigarette wrapper including cutting open the cigarette transported in a guiding groove of a feeder of a machine for recovering tobacco from defective and/or substandard cigarettes with at least one revolving disc knife located above the feeder, in which:

• the at least one revolving disc knife is applied to the cigarette in such a way that the geometrical axis of the said disc is slanted in relation to the axis of rotation of the said disc, the said axis of rotation lying on a plane parallel to the plane over which the cigarette axis is translated;
• the possibility of rotation of the cigarette around its axis in the guiding groove is blocked;
• whereby variable tensile stress is applied in the cigarette wrapper facilitating its opening.

Assembly for opening cigarette wrappers in a machine for recovering tobacco from defective and/or substandard cigarettes in which the cigarettes are translated to be cut along guiding grooves and at least one revolving disc knife is provided above each cigarette, each axis of rotation on which a disc knife is mounted lying on a plane parallel to the plane over which the cigarette axes move, characterized in that the plane of at least one disc knife does not comprise the axis of the cigarette and is parallel to the said axis and in that the assembly is provided with means for blocking the possibility of rotation of the cigarettes around their axes in the guiding grooves.
