Abstract
A machine for wrapping articles in an elongated strip of wrapping material of the type in which the machine forms the strip into a channel as the strip is advanced past the loading station, articles are deposited in the strip at the loading station, and the strip is folded into a tube around the articles and longitudinally sealed as the strip is advanced past a longitudinal sealing station, and the strip is thereafter transversely sealed between the articles and severed to form separate packages. The machine has endless type upper and lower jaw conveyors which are operated to grip and advance the strip through a selectively adjustable distance and seal and sever the strip to form packages of selectively adjustable lengths. The machine also includes an improved endless type of inlet conveyor which is operative to grip the enfolded strip of wrapping material at opposite sides of the article to hold the articles in position in the wrapping material as it is advanced. The machine is also adjustable to handle articles of different widths.
