Available Options:

  • Pneumatic feed belt actuation
  • Belt gap indicator
  • Alternate puller widths and contact lengths
  • Fully guarded puller assembly
  • Blade lubrication system
  • Cutter head on X-Axis slide assembly
  • Increased diameter self-aligning quick change bushings

  • External cut trigger tracking and length adjustment

 

ESI has developed our industry leading HAPC line of flycutting equipment which has produced in-line cut accuracy standard deviations of 0.002" at stop start cut rates of 650 cuts-per-minute. Our HAPC includes individual intelligent servomotors and drives for each belt of the puller and for the flyknife cutter.  The 3-axis, solid state servo programmable controller along with integrated touch screen operator interface display panel offers system cycle rate capability of 750 cuts-per-minute in 'On-Demand' mode, 2000 cuts-per-minute in 'Camming' mode and up to 3000 cuts-per-minute in 'Continuous' mode. These highly sophisticated machines have been used in applications automatically adjusting each individual cut length in response to feature locations sensed by a vision system at over 500 cuts per minute and locating multiple cuffs in corrugated tubing, trimming cuff length and tracking multiple different parts and separating into different bins off the packing conveyor.

Standard Features:  

  • 3“ wide x 18“ belt puller; each belt driven via individual brushless servo motor with ‘zero backlash’ planetary gearbox and controlled with individual intelligent servo drive
  • 130 In-Lb brushless servo cutter motor
  • Unique Self-Aligning ‘Quick change’ bushing assembly (No tools required for bushing changeover)
  • One-piece 3 ½” OD cutter bushing design
  • Direct coupled cutter motor & blade holder – no belts or clutches
  • System cycle rate is limited to 750 CPM in ‘On-Demand’ mode; 2000 CPM in ‘Camming’ mode and up to 3000 CPM in ‘Continuous’ mode
  • +/- .005” cut length accuracy capability (exclusive of product slippage, bow, curvature and shrinkage)
  • Cutter guard electrically interlocked
  • Puller assembly is locally guarded
  • Three axis solid state triple servo programmable controller
