Apparatus and method for producing a rod of aerosol-generating material

Apparatus for producing a rod of aerosol-generating material, the apparatus comprising:

• a first feed device adapted to supply a first web of aerosol-generating material to a processing unit;
• a second feed device adapted to supply a second web of aerosol-generating material;
• and
• a web changeover unit arranged to change supply of aerosol-generating material to the processing unit from the first web of aerosol-generating material to the second web of aerosol-generating material as supply of the first and second webs of aerosol-generating material towards the processing unit continues;
• wherein the web changeover unit is configured to position a leading edge of the second web of aerosol-generating material adjacent to a trailing edge of the first web of aerosol-generating material upstream of the processing unit such that said leading and trailing edges do not overlap, during changeover from the first web of aerosol-generating material to the second web of aerosol-generating material, and
• wherein the leading edge of the second web of aerosol-generating material and the trailing edge of the first web of aerosol-generating material are complementarily shaped, and wherein the leading edge of the second web of aerosol-generating material and the trailing edge of the first web of aerosol-generating material are diagonal relative to the direction of travel of the leading edge of the second web of aerosol-generating material and the first web of aerosol-generating material,
• wherein the changeover unit is configured such that the first web of aerosol-generating material and the second web of aerosol-generating material are not attached during change of supply of aerosol-generating material.
