摘要： Heat shrink wrap product packaging oven or tunnel apparatus and processing methods are provided which incorporate or utilize airfoils in conjunction with hot air-providing side walls to desirably control impact of hot air onto a product wrapped with a tube of heat shrink wrap film and being conveyed on a conveyor thereby. In such heat shrink wrap product packaging apparatus and methods, such airfoils can be movable, e.g., rotatably moveable, relative to the side walls to vertically alter an air impact point onto the product.

摘要： Heat shrink wrap product packaging oven or tunnel apparatus and processing methods are provided which incorporate or utilize a central divider mechanism. The central divider moves over a conveyor between a vertical, dual track position, and a retracted, single track position. The divider can additionally include a curved deflector that focuses and/or smooths air flow from the divider laterally across the dual track conveyance path.
