ABSTRACT:
Elongated quilted webs which have line out flaws are moved from a first container at high speed in a downward direction in front of an operator, then laterally through a sewing station toward the operator, then downwardly away from the operator to a second container. When a flaw in the web is detected by the operator as the web moves at inspection speed in a downward direction toward the sewing station, the operator allows the flaw to move through the sewing station and then stops the movement of the web. The operator then reverses the direction of movement of the web so that the flaw moves back through the sewing station at sewing speed where one of several sewing machines which is closest to the flaw is energized at the sewing station and operates concurrently with the movement of the web to sew through the web. The operator moves the sewing machines in unison back and forth across the direction of movement of the web so that the sewing machine in operation can follow the path of the flaw and the proper pattern can be sewn into the quilted web.
