Abstract
An assembly for the automated production of conical paper sleeves for plants uses paper stock precut in a trapezoid configuration which is continuously fed to the assembly. The precut sheets are folded diagonally twice to form a conical sleeve. The folding process includes application of an adhesive on the overlap of the folded sides to securely seal the sleeve. The precut sheets are transported along the assembly via a series of belts, rollers and electrical motors. The synchronization of the folding process and the application of adhesive is electronically monitored and controlled.
