High Precision Tubing and Profile Pullers and Cutters by Harrel

The ROLLERPULLER -- A Harrel Exclusive!

• MUCH, MUCH MORE UNIFORM SPEED. Eliminates serious variations in speed caused by stiffness variations in the belts of conventional pullers.
  
  
• MUCH, MUCH LOWER INERTIA. Much, much better performance for bump tubing applications. It is difficult to imagine a worse configuration for fast speed changes than a conventional belt type puller, with all the weight of a heavy belt out at maximum radius!
  
  
• Optional Harrel DIGISYNCH digital drive. Stabilized to 0.001% steady state regulation by precision crystal reference. 0.000% steady state regulation with load changes.
  
  
• DIGISYNCH synchronization to gear pump or extruder speed. Steady state synchronization is exact -- 0.000% steady state error!
  
  
• QUICK-CHANGE ROLLERS for ease of maintenance!

• Servo drive -- gives 100:1 speed range instead of 20:1 of standard drive. Required for bump operation.  $1450.
• Stand-alone DIGISYNCH speed control. Improves accuracy of drive to 0.001%  $1,850.00
• Auxiliary DIGISYNCH controller for synchronization  $1,750.00
  Similar controller to above, but mounts on remote drive (gear pump, extruder, etc.) to stabilize its speed and extrudate dimensions.  Requires digital encoder for remote motor.
• DT-102 digital tachometer for remote motor - 3 HP or less $525.00
• DT-120 digital tachometer for remote motor - 5 HP and up $1250.00
• Special paint $200.00

NO-CLUTCH Cutter -- Pioneered by Harrel!

• MUCH LONGER LIFE. No clutch or brake to wear out! Motor is brushless type!
  
  
• NO BOTHERSOME ADJUSTMENTS! No clutch or brake to adjust. Forget about having to adjust air gap -- there isn't any!
  
  
• LESS INTERRUPTION TO LINE. Knife is travelling much faster than in conventional clutch/brake cutters!
  
  
• FLEXIBLE. Demand mode to 600 cuts/min; Flywheel mode to 2500 cuts/min.
  
  
• CONVENIENT. Cut head slides back on ball bearings for easy string-up.

To 1" cut: NC-602 = $16,900.00
To 2" cut: NC-603 = $17,650.00

OPTIONS:

• Microprocessor controller: Allows cut length to be controlled by: $980.00
  • A predetermined time interval.
  • Predetermined length, from encoder in ROLLERPULLER.
  • On demand from photocell or switch closure
  A 4 digit pre-settable counter function is included, An output pulse is generated when the pre-set count is reached.
• AU100MF series tension bushing. Keeps a constant tension between puller and cutter on the piece to be cut. Allows cutting of materials of low stiffness -- the proverbial "wet noodle". Specify tubing size. $895.00
• AC100HW Knife lubrication system. Provides drip type lubrication for knife. $425.00
• Regular bushings. Stainless steel. Bored as needed. Please specify diameter of tubing. $385.00 for 1" cutter; $880.00 for 2" cutter
• 230-240V three-phase operation $440.00
• Special paint.$200.00
• Heated blade. Temperature controlled hot blade for difficult cutting applications. Consult factory for additional information. $3800.00

COMBINATION PULLER/CUTTERS

• COMBINES A HARREL ROLLERPULLER AND A NOCLUTCH CUTTER in one rugged and convenient cabinet.
  
  
• MAY BE INTEGRATED into Harrel TUBETROL, BUMP TUBETROL, or COEXTRUSION TUBETROL systems or operated on stand-alone basis, with optional cut control, which synchronizes the cut to a puller.
  
  
• PULLER SPEED MAY BE DIGISYNCH synchronized to extruder or gear pump with 0.000% steady state synchronization error.
