Description: |
| This patent was improved by patent #336,656.
Abstract:
Our invention relates to that method of radial crimping in which radial or diverging or converging crimps, folds, or fold-marks suitable for filtering-paper are produced in filter- ing-paper or other material by compressing the paper or material on the lines of the several folds between suitable and suitably-arranged radial or diverging or converging grooves and edges. When all the folds, fold- marks, or crimps required in a sheet of filtering-paper are made by the simultaneous action of a sufficient number of suitable grooves and edges, the several edges pressing against opposite faces of the intervening paper cause friction and produce a strain, which is liable to tear the paper while it is being drawn in between the said grooves- and edges by the simultaneous closing of the same grooves and edges upon the said intervening paper.
Claim:
In a machine for producing radial crimps or fold-marks, a stationary bed-plate or holder provided with grooves and edges radiating from a common center, in combination with a series of converging blades, and means, substantially as described, for actuating said blades successively, or one after another. |
