ABSTRACT:
A grid tee of the double web type in which the elements of the web are integrally stitched together to prevent their separation. The stitches are created in an inexpensive rolling process that does not require control of the position of the stitches relative to the ends or other parts of the tee. According to the invention, after the stitches are formed and locked, they are flattened back into the plane of the web to a limited degree where they do not substantially increase the thickness of the web so that they do not interfere with subsequent manufacturing steps or with field assembly.
