Abstract: A method and apparatus for stacking curved, triangular snack food chips, e.g., tortilla chips, for packaging in a sleeve-type container. The chips are fed into a first, U-shaped vibratory chute, which automatically causes the apex corners of the chips to extend beyond the opposing base edges of adjacent chips and which automatically orients the chips such that lines about which they are curved are oriented parallel to the longitudinal direction of the U-shaped chute. The chips are then fed into a W-shaped chute, with the chips facing in opposite directions falling automatically into opposite troughs of the W-shaped chute. The chips are then automatically reoriented by 120° such that their upturned apex corners point in the direction of travel, and the chips are stacked automatically as they slide up along one another in a shingled manner.

Abstract: An conveyor oven enclosure system is disclosed which includes a hood means which extends over the conveyor oven and supplies make-up air and exhausts heated air. The enclosure system includes front enclosure and rear enclosure walls which are parallel to and spaced apart from the front and rear oven walls of the oven respectively. Additionally, a first enclosure end wall is also included which is parallel to and spaced apart from the first oven end wall. A second enclosure end wall which is parallel to and spaced apart from the second oven end wall is also included. In the enclosure system of the present invention there is an entry opening in at least one of the enclosure walls which is adapted to correspond to each entry opening in the oven walls. An exit opening in at least one of the enclosure walls is provided which is adapted to correspond to each exit opening in the oven walls.
