ESI-Cutters
ESI flycutters are available in either high performance servo driven models or air actuated models. Both types are extremely low maintenance. Servo cutters are available with ASC for more demanding applications. The Airfly cutter is a pneumatically actuated, on-demand flyknife without friction surfaces normally associated with non-servo flycutters (which typically have clutch brakes) for simplicity and ease of use. ESI’s Accufly utilizes the stop/go technology also used in our Accupunch and Accusaw series. The servo-controlled feeder is automatically synchronized to the extrusion line by the dancer. This system, in conjunction with the fiber optic length sensing ensures the utmost cut length accuracy by feeding the product in a relaxed (non stretched) manner and ensures the optimum cut quality because the extrudate is stopped during the cut.
ESI offers a variety of cuff cutting solutions. These machines can be equipped with cuff clamping mechanisms (for better cut quality by supporting the smaller cuff diameter) in our Accufly series or can utilize our ASC technology to cut multiple cut lengths out of the same mold chain. Cuff cutouts can be removed in either design of cuff cutter.
For sheet products ESI offers a range of crosscut undriven rotary cutters, pneumatic and hydraulic shears and guillotine cutters. Systems can be setup for cut-to-length or cut-to-weight. Cut-to-weight is often utilized for applications producing prep stock for compression molding of rubber.
Our range of cutters is very expansive and also includes spin cutters for planetary cutting brittle polymers, spiral cutting tubing for wire/cable wrapping applications and fitting line or part identification printing hoses or other profiles using contact or non-contact printing methods.

Servo Cutter
For higher performance cutting applications, our servo driven flycutters are available with a variety of cutting torques and speeds. Brushless servomotors, directly coupled to the machined blade holder, drive these cutters. Since no friction wear surfaces such as clutch or brake assemblies are utilized, continuous adjustment or replacement to insure accuracy is a thing of the past. The base servo control provides for 'on-demand' cutting with simple operation through the standard interface. ASC servo cutters are also available with automatic camming allowing non continuous flyknife motion up to 1000 cuts per minute and continuous cutting up to 1400 ...
Accufly
ESI's Accufly® in-line cutting system offers innovative technology with high accuracy cutting by incorporating a servo driven stop/go feeder with fiber optics for cut-to-length signaling. Length is set by adjusting the fiber optic bridge assembly, or utilizing the servo feedback from the feeder motor. Just prior to the set length being reached, the feeder belts ramp down to ensure proper cut length positioning without overshoot. When the fiber optic beam is broken, the feeder belts stop and the servo driven flyknife is cycled, resulting in a square cut and high accuracy cut length. Because the feeder is maintaining a loop ahead of the Accufly, the product is fed without ...
Airfly Cutter
The patented Airfly cutting head was designed as a simple, efficient cutting device with very few moving parts for low maintenance. The Airfly is an 'on-demand' pneumatically powered flyknife cutter can be furnished as a 'table top' unit with basic controls. It is powered by multiple stainless steel air cylinders, and does not require the use of an electric or vacuum/clutch brake, has no linings to wear or replace, needs no electric motors or over-excitation circuits, and operates without the need for timing drums and belts. The Airfly is available in a standard 3.5" bushing size.
