Abstract:
1. A method for cutting and sealing two layers of film together near an edge of heat-sealable material by a side sealer apparatus comprising the steps of: providing a top drive roll spaced-apart from a top idler roll; providing a bottom drive roll spaced-apart from a bottom idler roll and positioned immediately under said top drive roll and top idler roll respectively; positioning a first pair of spaced-apart V-belts around and between said top drive roll and said top idler roll; positioning a second pair of spaced-apart V-belts around and between said bottom driver roll and said bottom idler roll; moving said heat sealable material through said side sealer apparatus; generating heat to cut and seal near said edge of said heat sealable material with means attached to a bracket suspending said heat generating means in an air space from a frame of said side sealer apparatus, and positioning said heat generating means at a predetermined angle relative to a horizontal plane of said moving means in the path of said heat-sealable material thereby removing excess film; locating said heat generating means in said air space between said V-belts positioned on an inner side of said heat generating means and said V-belts positioned on an outer side of said heat generating means; providing an elongated metal sheathed body having an internal heating mechanism and a thermocouple to generate said heat; and providing closed loop control of said heat generating means in accordance with a predetermined temperature setting with means connected to said heat generating means.
