Thickness Variation Responsive Patents (Class 242/485.4)
  • Patent number: 6533211
    Abstract: A method of operating a textile machine for producing cheeses, at whose workstations (1) yarn (2) is unwound from supply bobbins (3), checked, cleaned of yarn defects and wound onto larger-volume cheeses (4) during which the yarn defects occurring the winding process in a given yarn length are registered. When a predetermined number of yarn joinders is exceeded within a predetermined reference yarn length, the winding process is stopped and the yarn length with the excessive number of joinders, already wound onto the cheese, is removed from the cheese (4).

  • Patent number: 6409117
    Abstract: The present invention includes systems and methods for monitoring the spooling area of a rotatable reel for winding or unwinding an elongated material, for example, a cable. The monitoring system has a detector for sensing the presence and position of a cable surface or object or operator positioned between the detector and the reel. The detector can control rotation of the reel directly, or send a position signal to a computer where the position signal indicates the detected presence and/or position. The computer can have a memory and/or a processor for respectively storing and analyzing the position signal. The computer is operative to compare the position signal to previously received position signals to determine a condition, for example, the amount of cable on the reel, the presence of any object, and/or the existence of a safety-threatening condition. The computer can generate an output signal for use in, for example, controlling the reel speed and/or torque, or the application of brakes.
