A plant material assembly for separating cannabis plant material is provided having a plant material hopper configured to receive the cannabis plant material and feed the cannabis plant material to a plant material separator. The plant material separator is configured to separate undesirable plant material from desirable plant material by using a first roller, a second roller, and a third roller. The first roller and the second roller separating the cannabis plant material into the desirable plant material and the undesirable plant material by sending the desirable plant material in a first directional path and the undesirable plant material in a second directional path. Next, the third roller is used in relation to the first roller and the second roller, wherein the third roller redirects the undesirable plant material from the second directional path into a third directional path and finally into a catch depository.

A machine for making plant material smoking articles is provided having a feeding assembly that is configured to feed plant material to a combustible material rolling assembly. The combustible material rolling assembly includes a continuous stream of paper and a forming chute having a semispherical channel at a length and at least one adjustable guide. The combustible material rolling assembly is configured to roll the plant material in the continuous stream of paper at a wrapping rate within the semispherical channel to make at least one plant material smoking article. In some embodiments, the feeding assembly is either driven via gravity or a pneumatic delivery system. In one embodiment, at least one adjustable guide includes a tapered conical guide configured to additionally adjust the wrapping rate.

A rotational transfer assembly is provided to transfer at least one smoking article from a combustible material rolling assembly to a filter assembly. The rotational transfer assembly includes a transfer wheel configured to rotate in a rotational direction at a rotational speed and a plurality of transfer elements attached and positioned radially to the transfer wheel. Each of the plurality of transfer elements is configured to receive a smoking article traveling in a first direction at a linear speed from the combustible material rolling assembly. Next, each transfer element comprising a member of an air component set holds and retains the smoking article on the transfer element during rotation. In some embodiments, each transfer element of the plurality of transfer elements includes a semispherical shaped engagement surface configured to engage the plant material smoking article. In operation, the rotational speed and the linear speed is synchronized by the smoking article machine and a control assembly.

A device and method for cleaning flowers and buds of plants of leaves and plant matter and particulate is provided. The buds are cleaned within a rotating drum having openings in a circular sidewall which rotates adjacent jets emitting gas. Freezing of the plant material and concurrent impacts from ice crystals formed by emitting gas, cleans the buds and flowers of unwanted plant material and particulate.

A firefighter hood comprising a hood body configured to fit around a head of a wearer, wherein the hood body includes a face opening configured to be aligned with a face of the wearer when the hood is worn. The hood further includes a flap coupled to the hood body. The flap is movable between an extended position wherein the flap covers only part of the opening in front view, and a retracted position wherein the flap does not cover any of the opening in front view or covers less of the opening in front view compared to when the flap is in the extended position.

Example embodiments include a system for removing string from shredded tobacco, including an arrangement configured to dispense shredded tobacco from a first location to a second location along a path of communication, a string filter operative at a location along the path of communication comprising a first roller comprising pins, whereby string may be contacted by at least some of the pins and retained at the string filter as the shredded tobacco passes through the filter.
