    • A system for sealing a packaging wrapper around an object directs a flow of heated air to end flaps of the wrapper to move the end flaps into sealing contact with a body section of the wrapper to substantially enclose the object. The system includes an oven, a conveyor, a source of heated air and a means for deflecting the flow of heated air to the conveyor to seal end flaps of the wrapper with a body section of the wrapper. In use, an object surrounded by the wrapper body section is moved through the oven on a conveying surface of the conveyor, and heated air is moved through the oven bypassing the conveying surface to a region below the conveying surface. The heated air flow then encounters the means for deflecting the heated air flow, which directs the air flow upward and through the conveying surface to impact and move the end flaps into sealing contact with the wrapper body section.
    • 用于将包装物封闭在物体周围的系统将加热的空气流引导到包装纸的端部折片上,以使端部翼片与包裹物的主体部分密封接触以基本上包围物体。 该系统包括烤箱,输送机,加热空气源和用于将加热的空气流偏转到输送机的装置,以用包装纸的主体部分密封包装纸的端部折片。 在使用中,由包裹体部分包围的物体在输送机的输送面上移动通过烤箱,并且加热的空气通过旁路输送表面的烘箱移动到输送表面下方的区域。 加热的空气流然后遇到用于偏转加热的空气流的装置,其引导空气流向上并通过输送表面以冲击和移动端翼片与密封接触包裹主体部分。
