  • Method of sequenced braider motion for multi-ply braiding apparatus
    Patent number: 4621560
    Abstract: A braiding method wherein fiber carriers are arranged in rows and columns which are moved in a predetermined alternating sequence to intertwine the fibers and form a braided article. A selected intermediate row is moved a distance sufficient to block movement of a column on one side thereof. While the column is blocked, a tamping force is applied thereto to move it against the one side of the selected row to facilitate proper alignment of the fiber carriers in the column.
