Smoking article machine

A method for making cannabis smoking articles comprising desirable cannabis plant material, the method comprising steps:

• (a) providing cannabis plant material having desirable cannabis plant material and undesirable cannabis plant material wherein the desirable cannabis plant material includes cannabis flowers and the undesirable cannabis plant material includes one of cannabis stems and cannabis seeds;
• (b) feeding the cannabis plant material into a hopper, wherein the hopper is configured to feed the cannabis plant material to a plant material separator;
• (c) separating, via the plant material separator, the cannabis plant material into desirable cannabis plant material and undesirable cannabis plant material, wherein the plant material separator includes a first roller, a second roller, a third roller and a fourth roller, the first roller having a first diameter configured to rotate in a counterclockwise direction at a first speed, the second roller having a second diameter configured to rotate in a counterclockwise direction at a second speed, the third roller having a third diameter configured to rotate in a counterclockwise direction at a third speed, and a fourth roller having a fourth diameter configured to rotate a clockwise direction at a fourth speed;
• wherein the first roller and the second roller are positioned such that the cannabis plant material is pressed between the first roller and the second roller separating the cannabis plant material into the desirable cannabis plant material and the undesirable cannabis plant material, sending each plant material in a first directional path;
• wherein the third roller is positioned in relation to the first roller and the second roller, the third roller configured to redirect the undesirable cannabis plant material from the first directional path onto a second directional path;
• wherein the fourth roller is configured to guide each plant material to the third roller;
• and wherein the first directional path is in a generally downward direction such that the desirable cannabis plant material passes between the second roller and the third roller onto a feeding assembly;
• (d) catching, via a catch depository, the undesirable cannabis plant material;
• and,
• (e) feeding, via the feeding assembly, the desirable cannabis plant material to a combustible material rolling assembly configured to produce a smoking article comprising the desirable cannabis plant material.
