  • Magnetic position marker and control system for production of felt
    Patent number: 5349728
    Abstract: A magnetic marker comprising a plurality of magnetized fibers oriented substantially parallel to each other is attached to a fringe of ground fabric for production of felt in the form of an endless belt for detecting the travel of the ground fabric and changing various production parameters according to the number of turns which the ground fabric makes around a series of rolls for causing the movement of the ground fabric. Since the magnetic marker consists of extremely thin magnetized fibers, it can withstand the repeated piercing by needles which is required for the production of felt for the purpose of entangling the fibers of fiber web with the ground fabric.
