Description: |
| This patent is an improvement of patent #284,749.
Abstract:
Our invention relates to that class of machines in which the crimps, folds, or foldmarks in filtering-paper or other material are produced by first folding the sheets through the center and then crimping the folded sheets between intermeshing edges.
In the machine for radial crimping described in Letters Patent No. 284,749, dated September 11, 1883, the folded sheets are crimped between radially arranged or diverging intermeshing edges. A series of blades or edge-holders, beginning at one side of the machine aind at one edge of the folded sheet, one after another consecutively force the paper against the edges and into the grooves of a stationary bedplate.
Claim:
In a machine for radial crimping, a series of intermeshing blades arranged to move in parallel planes and to overlap in forming the crimps to correspond with the increasing or diminishing width of fold required in radial crimping. |
