A paste sector for applying paste in a predetermined pattern to an item being manufactured, such as to the open bottom portion of a partially formed bag in a bag making machine. The paste sector is molded from a substantially resilient non-metallic material, and includes an added-thickness bottom portion adapted to be directly fitted to a paste sector shaft. The paste sector is preferably injection molded from a rubber-like urethane material, and is provided with a Teflon coating having an affinity for the low viscosity paste employed in the fabrication of paper bags.
