Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
96 words
In 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, the improvement comprising the steps of: moving a selected intermediate row a distance sufficient to block movement of a column on one side thereof, and applying a tamping force to said column to move it against said one side of said selected row while it is blocking movement of said column, whereby said column is temporarily shortened to facilitate proper alignment of the fiber carriers therein.
Claim 2
Dependent Claim
96 words
In 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, the improvement comprising the steps of: moving a selected intermediate row a distance sufficient to block movement of a column on one side thereof, and applying a tamping force to said column to move it against said one side of said selected row while it is blocking movement of said column, whereby said column is temporarily shortened to facilitate proper alignment of the fiber carriers therein.
Claim 3
Dependent Claim
35 words
The braiding method of claim 1 comprising the further step of moving said selected row to a position wherein it does not block movement of said column after the tamping force has been applied thereto.
Claim 4
Dependent Claim
21 words
The braiding method of claim 2 wherein movable stop cams are utilized to control the movement of said selected intermediate rows.
Claim 5
Dependent Claim
56 words
The braiding method of claim 1 wherein selected intermediate rows are sequentially moved a distance sufficient to block movement of columns on one side thereof, and a tamping force is sequentially applied to said columns to move them against said one side of each of said selected rows as they are moved to said blocking position.
Claim 6
Dependent Claim
15 words
The braiding method of claim 4 wherein said selected intermediate rows are substantially uniformly spaced.
