Explanation:
"Closed-loop Die Accelerator Systems

While an open-loop system can achieve high speeds and solid accuracy, its results depend significantly on the training and experience of the operator and maintenance staff. A closed-loop system, however, can produce good results consistently, with minimal attention and maintenance.

A closed-loop die accelerator system uses a positioning device that controls the location of the die across the entire stroke length of the press. When a cut is made, the positioning device moves the die directly over the cut point, keeping it traveling at the same speed as the material and tracking throughout the entire press cycle (see Figure 3).

Because the die and the material are traveling at the same velocity, the cut is made at virtually zero speed—as if it were a standing cut—resulting in a clean cut without strain on the material or on the die. This eliminates collision between the material and the die and allows increases in line speed without part damage, improving part quality and extending the life of the cutoff die. Once the cut is performed, the positioning system returns the die to its home position to await the next target.

A closed-loop die accelerator's main advantage is that it can make adjustments throughout the press cycle on the fly through its feedback systems. It can achieve consistency and accuracy in a variety of conditions without continuous oversight. Length control is accurate without speed constraints and with almost no setup time for length changes. Parts lengths remain accurate over a range of machine conditions.

Initial equipment cost is high for closed-loop systems because of the required precision die-positioning system. However, increased line speeds, scrap savings, and reduced downtime can help justify the investment.

The cycle rate of any roll forming machine's cutoff press limits the minimum part length that can be run at a given line speed. A closed-loop die accelerator actually limits this speed further and lengthens the cycle rate of the cutoff operation. Before a cut, the die must be accelerated to line speed; after the cut, the die must be decelerated to a stop, accelerated in the reverse direction, and decelerated as it approaches the home position.

With so much die movement, shorter parts must be run at lower line speeds. However, because a closed-loop die accelerator adapts to line speed changes, the machine can be slowed down for short lengths and immediately sped up for longer lengths with no downtime or deterioration of accuracy."

I originally thought "cortes" might have meant "eletrical outages," but I think it is actually referring to "cuts" here.

At any rate, hope this helps some!
