Width control system LF-Sizer

industrialautomatic

The LF-Sizer layflat control system reduces runaway resin produced when layflat is oversized to compensate for gradual size loss common when no width control system is present. In addition, by attending to the width automatically, bubble drops (losing the bubble entirely because of a hole) are minimized resulting in up to 7% more production per month (based on an actual case study). By measuring the bubble soon after the frost line, the system can achieve the proper bubble size quickly. The LF-Sizer control system is flexible and comes with the widest variety of configuration options available in the industry. The system can be used on small dies and large dies alike. Some of the configurable features include automatic startup, on-the-fly size changes, process alarms, bubble break output, statistical reporting and industry standard communication interfaces (including RS232 and Ethernet). Installation is quick and easy, no electrical terminations required. Standard compressed air of at least 70psi (~5 bar) is required. The three speed (fast inflate, slow inflate and deflate) pneumatic control box is separate from the control system electronics. This ensures the electronics are not exposed to wax and oils pulled from the bubble during deflation. A Sizing cage is beneficial but is NOT required. For HDPE / MDPE high stalk bubbles, an optional add-on control feature for neck height control is available. See more in Neck Height Control below.
