Abstract
In a spiral tube winder, the plies going to the winding mechanism are monitored to make sure that no ply is broken. If any ply breaks, the machine is stopped so that the broken ply does not become entangled in the apparatus, especially in the glue applying portion of the apparatus. The ply break detection system is automatically activated for each ply lane that is in use so that plies can be added while the machine is in operation, with the result that the ply break protection for each such added ply comes on automatically after that ply has been added.
