Method for wrapping loads with tubular stretch film
The patent US12060192B2 outlines a method for wrapping a load using multiple segments of tubular stretch film. The process involves a reefing-and-wrapping assembly that applies a first segment of the film to the load by either moving the film or the load in a specified direction. A second segment is then applied in a different direction, ensuring that both segments enclose the load completely. The claims detail various configurations, including horizontal and vertical directions for the application of the film, as well as the possibility of sealing the ends of the segments to secure the load. The method allows for flexibility in the application sequence and the sealing process, which can be adjusted based on the specific requirements of the load being wrapped.
Additionally, the patent describes the formation of reinforcing zones within the first segment of tubular stretch film, which can encircle different parts of the load, particularly when the load consists of multiple rows of components of varying widths. This feature enhances the stability and integrity of the wrapped load. The claims also specify methods for adjusting the application speed and the rate of unreefing the film to optimize the wrapping process. Overall, the patent presents a comprehensive approach to load wrapping that accommodates various load configurations and enhances the effectiveness of the wrapping process through innovative techniques.
