Abstract
An apparatus and method of severing netting is disclosed. Pressurized air is heated to a temperature sufficient to sever netting. The hot, pressurized air is directed through a nozzle at a neck of gathered netting to sever the netting. A controller controls a motor to move the nozzle through an arc to direct the hot, pressurized air at the neck, and controls a valve to release the hot, pressurized air at the proper time. The nozzle can direct a jet of hot, pressurized air at the netting or can form a chamber having an aperture, wherein the hot, pressurized air contacts the neck of gathered netting in the aperture.
