ESI Puller-Cutters

Precision in-line cutting of extruded profiles and tubing requires a very high degree of co-ordination between the extrudate and the flyknife. ESI has focused on this relationship for years in improving the system responsiveness and eliminating program scan times effect. Our strong background in motion control, utilized on all of our ASC series, has allowed us to stay at the forefront in cutting technology. Having a stable puller is crucial to the consistency of the profile size and allows an even tighter relationship between the motion of the flyknife blade and the extrudate.

From our inception ESI has been an industry leader in the design and manufacture of precision in line cutting equipment and offers the widest range of puller-cutters in the industry. ESI puller-cutter combinations are offered with a variety of choices in drive configurations, cutter torques and speeds and control systems. All ESI puller-cutters feature our unique quick change, self-aligning bushing system, allowing cut bushing changeover in seconds without the use of tools. From our economical, low maintenance SPC models, to our industry leading HAPC series of high precision, servo controlled puller-cutters; ESI provides puller-cutter models designed to meet the requirements of your specific cutting application.

ESI offers also highly sophisticated Puller-Cutters for use as cuff cutters on corrugated tubing.  More information can be found in our cutters section.

Triple Servo Puller-Cutter

Combines industry leading cut length accuracy with a robust machine platform providing unmatched reliability and precision for inline and offline cut to length applications.  Our cutting-edge omniscient motion controls package is spearheaded by independent directly driven servomotors and intelligent drives for each puller belt and for the fly knife cutter.  This paramount flycutter has been used extensively for applications which demand critical cut length tolerances with coordinated automation such as: automatically adjusting individual cut lengths in response to feature locations sensed by vision systems, locating multiple cuffs in corrugated tubing, trimming cuff length while tracking multiple different parts, and separating into different bins off the packing conveyor.

ASC (Advanced Servo Control) Puller-Cutter

ESI's dual servo puller-cutters are designed to meet a wide range of in-line flycutting of plastic and rubber tubings and profiles. Precision in-line cutting of extruded profiles and tubing requires the extrudate to be presented to the cutter at a consistent rate. Our dual servo puller-cutter unit includes a fully programmable motion controller, color touchscreen, servomotors for both puller & cutter. System offers a cut length accuracy of +/- .010" with electronic camming of blade motion to achieve peak blade speed at any cut rate up to 1000 cuts per minute and a continuous cut mode of up to 1800 cuts-per-minute.
