Spliceable sheet stock material for dunnage conversion machines
The patent US12037211B2 outlines a supply of sheet stock material specifically designed for use in dunnage conversion machines. The invention features a multi-ply sheet material that includes a center section flanked by lateral sections, which are folded over the center section along longitudinal fold lines. The design incorporates a splicing adhesive that consists of at least two discrete segments, strategically placed on the lateral sections near the leading and trailing edges. This configuration allows for easy splicing of the sheet stock to another supply, enhancing the efficiency of the dunnage conversion process.
Further claims detail the structural aspects of the sheet stock material, including the separation of lateral sections from the center section by cuts along the fold lines, with specified distances ranging from one to fifteen centimeters. The patent also describes configurations involving two plies of sheet material, with inwardly folded lateral sections, and the possibility of creating a rectangular fan-fold stack through periodic folding. Additionally, the use of kraft paper in at least one ply is mentioned, along with the option of employing double-sided tape as the splicing adhesive, which features a removable release liner. These innovations aim to improve the functionality and usability of dunnage materials in various applications.
