Patent ID: 6912830

Claim:
A method for wrapping a series of products of differing heights in film, the method comprising the steps of: serially feeding a first and a second product in a feed direction to a wrapping station, a height of the first product being different than a height of the second product; delivering film to the wrapping station from a supply of film, the film having first and second plies joined together along a longitudinal fold line, each of the first and second plies having a free edge spaced from and generally parallel to the longitudinal fold line and a first face opposite from a second face, the respective first faces of the plies being juxtaposed to one another prior to arrival at the wrapping station; inverting the film with a first and a second film inverter rod at the wrapping station, the film inverter rods being spaced from one another; wherein the film inverter rods cooperate to invert the first and second plies so that the respective second faces of the plies are juxtaposed to one another after the film is inverted; wrapping the first product with the film at the wrapping station; adjusting the spacing between the film inverter rods after the first product exits the wrapping station, the spacing being adjusted to correspond to the height of the second product; adjusting a position of the supply of film relative to the film inverter rods in a direction generally parallel to the feed direction to provide for proper delivery of the film to the wrapping station as a function of the spacing between the film inverter rods; and wrapping the second product with the film at the wrapping station.
