A single gum stick wrapping machine has a rotary transfer mechanism for successively conveying single sticks of gum from breaker wheels to a folding wheel where each stick picks up a wrapper and is conveyed through folding and creasing sections where the wrapper is partially folded around the stick and the ends of the wrapper are folded, creased and tucked. The wrapping operation is completed while the partially wrapped stick is conveyed from the folding wheel to a stacker at the discharge end of the machine by another rotary transfer mechanism. Rotary label wrapping mechanism may be provided for applying a label or outer wrapper to each stick.

A gum stick wrapping machine comprising a gum stick breaker mechanism including a rotary gum stick transfer mechanism for cntinuously conveying gum sticks away from said breaker mechanism, a first rotary folder including means defining an arcuate first folding channel communicating with said rotary stick transfer mechanism for receiving each successive stick therefrom, a first rotary element journalled for continuous rotation relative to said first folding channel and having a series of circumaxially arranged and radially outwardly extending flights for engaging sticks in said channel to continuously convey the sticks therealong, said first folding channel having first folding means for folding an inner wrapper to a generally U-shaped configuration about a stick advancing therein to fold one end portion of the inner wrapper against the lower face of the stick to bring the other end portion of the inner wrapper into trailing relation with the upper face of the stick and the opposite side marginal portions of the inner wrapper into outwardly extending relation to the opposite ends of the stick, second folding means associated with said first folding channel for engaging and folding the side marginal portions of the inner wrapper downwardly relative to the stick and against the opposite ends thereof and tucking the side marginal portions inwardly toward each other and below the lower face of the stick and into trailing relation with the lower face as the partially wrapped stick is advanced within said folding channel by said first rotary element, third folding means associated with said folding channel for engaging the trailing portions of the inner wrapper and folding the trailing portions of the previously folded and tucked side marginal portions upwardly relative to the stick and against the trailing edge of the stick and into face to face engagement with the lower surface of the trailing upper end portion of the inner wrapper as the partially wrapped stick is continuously advanced within said first folding channel by said first rotary element, and drive means for continuously rotating said first rotary element in timed relation to said breaker mechanism and said gum stick transfer mechanism.
