High Speed Dual Drive Precision Roll Feed Equipment

Red Bud Industries has rarely taken the path of least resistance when it comes to equipment design. We have always tried to think “outside of the box” in our approach to engineering in an effort to give our customers definitive advantages in the markets where they compete. Keeping with this tradition, we developed a direct “dual motor drive” Precision Servo Roll Feed that improves upon the traditional Roll Feed designs.

How Roll Feeds Work

Traditional Roll Feeds use a single input AC motor with dual output shafts to the Feed rolls. Although these systems normally use “anti-backlash” gearboxes, they still contribute to length inaccuracy. In addition, torsional flex in the drive shafts also contributes to Feed inaccuracy, especially in heavy gauge applications where you are moving a lot of weight.

Our Roll Feed Equipment has been designed with independent AC motors mounted directly to the Feed rolls. This design eliminates gearbox “knock” and virtually eliminates length variances that originate from “slop” in traditional gearboxes, as well as torsional flex in the drive shafts, even on applications running up to .375” (9.5 mm) material.

Closed Loop Control System

A closed loop control system is used in tandem with the new dual drive design. The intricate control system utilizes position feedback from both the top and bottom rolls, as well as a separate wheel that follows to ensure unsurpassed part length accuracy. In addition to precise part lengths, this system can detect even the most minuscule roll/material speed differential to help prevent roll marking and various other complications that arise from roll slippage.

Intelligent Servo Roll Feeds

In addition to superior length accuracy, our Roll Feed Equipment offers automatic “intelligent” roll gauging to provide unrivaled squareness tolerances. Varying width mill edge coils are easily accommodated through the use of the intelligent gauging roller guides to maintain proper centering throughout the sheet feeding process. The “push” pressure of the guides also adjusts automatically depending on the thickness of the material being processed. This distinct feature drastically reduces the chance of damaging the edge of light gauge material and aids in preventing damage to the guide system while processing heavy gauge material.

Optimal Roll Feed Speed & Production

As every company knows, time is of the essence. Using this system, the operator can change part lengths with a push of a button. Our design allows part lengths to be changed on the fly without having to stop for set up time. Our Roll Feeds can also reach nearly instantaneous feeding speeds of up to 600 FPM (183 m/min) and production speeds up to 25 ten-foot (3.0 meters) or 18 twenty-foot (6.0 meters) parts per minute. With these high speeds, your company is guaranteed to get the optimal production numbers they need to stay a step ahead of the competition.

Another key to maximum production is, of course, minimal maintenance down time. Our Roll Feed Equipment is designed to withstand even the most challenging environments and is backed by Red Bud’s industry leading 5 Year Warranty. Our Servo Roll Feeds require less maintenance due to their simplification in design and nature of operation, ultimately resulting in more time for production.

Our Servo Roll Feeds:

  • Feature the best “real world” cut to length tolerances in the industry regardless of material width or thickness
  • Can process surface critical material without marking
  • Produce higher line speeds without experiencing material slippage
  • Include a 5 Year Warranty with lifetime access to our 24/7 “Service Hotline”
