The Automatic Width Control System gives you the customer, three options for maintaining a specific bubble size during normal operation. These options are ideal for managing on-the-fly size changes, reducing the time it takes to get the bubble on size and also minimizing changes in lay flat due to temperature conditions or film stretch. Options two & three, as described below, offer optimum systems for gusseted film.
Features of width control system:
Simple to install and operate
Lay flat or Ultrasonic measurement available
Suitable for all film types and colors
Displays instantaneous width and average width
Automatic monitor and fail-safe alarm
Measures 0 – 393.7”
Measurement resolution 0.004”
Display resolution 0.04”
Readily expandable and upgradable
OPTION 1: LAY FLAT MEASUREMENT
A single Layflat scanner houses two dynamic infra-red sensors which automatically seek and track the edges of the film irrespective of color or thickness.
OPTION 2: BUBBLE DIAMETER MEASUREMENT
(Optional) 3 x ultrasonic sensors can be positioned around the circumference of the film, situated just above the frost line, to measure the bubble diameter.
OPTION 3: COMBINED LAY FLAT & ULTRASONICS
(Optional) Both the Lay flat & the Bubble Diameter Measurement system are combined to give the finest automatic width control system on the market. (Either option computes the width correct to the nearest 0.004”. A control action proportional to any error is initiated via the TSM Air Correction Unit.
NOTE: - For fully rotating dies, an air compressor in conjunction with a radio transmitter and receiver is used.
The system electronics consists simply of a single board computer with power supply and operator panel. This modular design coupled with comprehensive diagnostic software ensures that the Width Control System can be easily installed and maintained by plant personnel.
The lay flat Width Control System is coated in a hard wearing, low friction proprietary PTFE coating, incorporating infrared edge sensors that are unaffected by film colors or ambient light. Status indicators of both width and limit sensors are included for diagnostic purposes.
