Tension controls, namely, brakes and clutches for machinery for production and processing of web, composite, tow, tape, or fiber products Electronic tension controls for production and processing of web, composite, tow, tape, or fiber products
Apparatus and methods are provided for a self-contained tension control system. An example self-contained tension control system can include a brake system configured to provide tension friction to a web, a tension transducer to provide tension information indicative of tension of the web, a controller configured to receive the tension information, to compare the tension information to set point information, and to provide a command signal to the brake system, and an enclosure configured to enclose the brake system, the tension transducer, and the controller, the enclosure including a first web opening and a second web opening configured to allow the web to enter the enclosure and to pass through the enclosure to equipment downstream of the self-contained tension control system.
B65H 23/06 - Registering, tensioning, smoothing, or guiding webs longitudinally by retarding devices, e.g. acting on web-roll spindle
B65H 23/10 - Registering, tensioning, smoothing, or guiding webs longitudinally by retarding devices, e.g. acting on web-roll spindle acting on running web

Apparatus and methods for web tension control are provided. In an example, an apparatus can include a tension beam configured to deflect in a predictive manner when under a force load, a first shaft directly coupled to the tension beam and configured to mechanically interface with a torque device, a second shaft directly coupled to the tension beam opposite the first shaft and configured to interface with a structural member of a web machine, and a strain gauge coupled to the tension beam and configured to provide an electrical representation of the force load.
B65H 23/04 - Registering, tensioning, smoothing, or guiding webs longitudinally
G01L 5/04 - Apparatus for, or methods of, measuring force, work, mechanical power, or torque, specially adapted for specific purposes for measuring tension in flexible members, e.g. ropes, cables, wires, threads, belts or bands
G01L 3/10 - Rotary-transmission dynamometers wherein the torque-transmitting element comprises a torsionally-flexible shaft involving electric or magnetic means for indicating
B65H 23/188 - Registering, tensioning, smoothing, or guiding webs longitudinally by controlling or regulating the web-advancing mechanism, e.g. mechanism acting on the running web in connection with running-web

BRAKES, CLUTCHES AND SAFETY CHUCKS FOR COMMERCIAL AND INDUSTRIAL MACHINES [ ELECTRICAL MEASURING INSTRUMENTS, NAMELY, LOAD CELL-BASED, DANCER-BASED, ULTRASONIC-BASED TENSION CONTROLLERS AND INDICATORS AND, LOAD CELLS AND LOAD CELL AMPLIFIER MODULES FOR INDUSTRIAL AND COMMERCIAL USE ]
An under-pillow bearing (UPB) load cell for controlling tension in the winding process for a continuous web of material. The load cell has a deflection and sensor assembly that is quickly and easily removable from the load cell for maintenance and repair. The deflection and sensor assembly includes a load beam that is insertable into the load cell. In one embodiment, a pluggable sensor insert may be inserted into or removed from the load beam, without removing any of the fasteners that mount the load cell to the machine support.
