Abstract
In apparatus for forming cut lengths of tube by winding one or more strips of material into a continuously advancing spiral wound tube and periodically cutting off lengths of the tube, lengths of tube containing splices present in the strips are rejected at a rejection point downstream from the cut-off point by monitoring the strips for splices prior to winding, waiting until enough strip has passed the splice monitoring point to extend from the splice monitoring point to the rejection point, and rejecting the length of tube at the rejection point when that amount of strip has passed the splice monitoring point.
