ABSTRACT:
A cushioning conversion machine for converting a sheet-like stock material, which may be viewed as having two edge sections and a central section, into a cushioning product is provided. The machine includes a conversion assembly for converting the sheet-like stock material into a cushioning product and a supply assembly which supplies the sheet-like stock material to the conversion assembly. The stock material is supplied to the conversion assembly in such a manner that its edge sections must travel in a longer path than the central section thereby creating edge-tension in the edge sections of the stock material. While a certain minimum conversion-tension is necessary in the edge sections of the stock material to properly convert the stock material into a cushioning product, a certain continuous tearing-tension, greater than the minimum conversion-tension, will cause a continuous tear in the stock material. To insure that the edge-tension is not so great as to cause continuous tearing but is great enough to allow proper conversion, the supply assembly includes an edge-tension controlling device which controls the edge-tension so that it is greater than or equal to the minimum conversion-tension and less than the continuous tearing-tension.
