Slitter Scorers "HSS5"

Super fast setup with a motor for each head. Since each slitter head has its own schedulable sharpener, only those blades needing sharpening are sharpened, ensuring optimum slitting conditions and no unnecessary sharpening.



The two-unit HSS4 is our high-speed order change model. Derived from that concept is our one-unit Slitter Scorer HSS5, a first in the industry.

We were again the first in the industry to develop a high-speed one-unit Slitter Scorer.

First one-unit Slitter Scorer in the world. A space saver at a low cost.
Average order change time of 0.3 seconds. Although a one-unit machine, only one sheet is lost per order change. (Only a one meter loss at 200m/min.)
With the standard Hyper Changer, trim can be automatically processed consecutively. Reducing the possibility of jamups almost to zero. Very high-precision control and alignment is very accurate.
Servo motors are used for blade engagement and also for the fine adjustment of blade engagement depth. Use the as much of the blades as possible.
The scrap sheet at an order change can be used as a tie sheet for the order. May achieve loss of zero in reality.

0.3-second Average Positioning Time for each head

Explaination of how ISOWA reduced the order change loss in the slitter scorer.

  1. Agile movements assuring high accuracy
    >> Moving parts are made of the lightest materials for the required strength.
    >> All movements are servo-motor driven.
  2. Limited the load/unload travel distance for instant loading and unloading.
