Abstract
In the present invention an elongated fabric web is advanced horizontally across a table by motor-driven rollers in a horizontally pivoted web forming device. The web forming device folds the web up along longitudinal fold lines before passing it through an opening in a metal fastener member held upright by a horizontally pivoted holder. The web forming device is pivotally retracted upwardly, and a web folding device folds over the leading end of the web and also rocks the holder to move the fastener member to a substantially horizontal position during this fold-over operation. A label is applied to the top of the web before the fold-over operation. The folded-over web and the applied label are slid across the table by a transfer device to a position where an automatic sewing machine sews a permanent end loop in the web and sews the label to the web next to this end loop.
