MSR dramatically simplifies the VTL turntable mechanical transmission system. In many cases, it is also much more economical.
Up to now, the conventional solution for VTL turntable drives has been composed of: a main drive (single motor and output pinion) for turning operations and a separate preloaded gearbox (Dual Pinions) for C-axis drive milling and drilling operations. This complex expensive gearbox requires a clutching mechanism to disengage it from the table during turning operations.
REDEX ANDANTEX is introducing a new solution to the market. It benefits from new drive and control system technology (for example Siemens CNC or Fanuc).
This new drive is composed of two identical gearboxes (twin pinions) sharing the driving torque (50%-50%) during turning operations. Then, during C-Axis operation, the CNC system manages a motor preload torque to cancel backlash. One motor is driving and the other motor is braking enabling very accurate positioning for precise milling and drilling operations without the need for a separate dual pinion gearbox.
REDEX ANDANTEX has developed a turnkey solution for this new drive arrangement consisting of a MSD 2-speed gearbox combined with the R SERIES spiral bevel gearbox.
This new solution is much simpler and more cost effective when applied to new turntable designs or retrofits for two reasons. First it eliminates the need to develop a complex and expensive gearbox with clutching mechanism for C-Axis. Second the main drive motors are 1/ 2 the size of a conventional solution because they share the load 50/50 during turning operations.
The new range consists of 7 sizes with torque capacity at 1 / 2 pinions up to 12,000 / 24000 NM and possible turntable torques from 20,000 NM up to 270,000 NM.
Reducing aircraft weight is essential to boosting fuel efficiency. Not only is it very important in terms of cost, but also given the ever-increasing distances that airplanes of the future are expected to travel more capacity is essential. Carbon fiber’s high strength to weight ratio is one of the main innovations today, but the need for high production rates requires extremely complex machines. Electroimpact has developed an outstanding solution offering a 2000 inch per minute (50-meter per minute) automated fiber placement speed. This means a very sophisticated control system and very stable and accurate axes drive systems. Andantex USA provided all the critical mechanical components to drive the axes.
Electroimpact is a young engineer driven company whose mission is to be the premier supplier of automated equipment to the worldwide aircraft industry. Electroimpact has developed Automated Fiber Placement (AFP) technology that allows cutting and adding carbon fiber strips (tow) within customer-end placement tolerances at rates up to 2000 IPM over ramped, complex surfaces. All layups can be performed fully bi-directionally and with operator control over the feed rate with no effect on end cut accuracy. Electroimpact is a highly experienced provider of factory automation and tooling solutions. The Company’s forte is the integration of automation and tooling into synergistic production solutions. Highly skilled engineering teams allow for the flexibility to take on multiple large projects at one time. This unique approach has resulted in Electroimpact growing to become the largest integrator of aircraft assembly lines in the world. The customer base includes commercial and military aircraft manufacturers throughout the world. The most recent customer is a large US aircraft component manufacturer. They manufacture Fuselages, Under-wing components, Composites and Wings for the aeronautic industry. The company’s headquarters are in Wichita, Kan., the Air Capital of the World, with additional operations in Tulsa and McAlester, Okla., Prestwick, Scotland, and Samlesbury, England.

ETI Converting Equipment is a company specialized in the design of machines for the manufacture of self-adhesive label equipment and printing presses. Recently, ETI Converting Equipment developed a revolutionary process for the application of a treatment on the parent material that increases the adhesive capacity of the ink, glue, or any other coating. Result: the printer can now purchase a much cheaper non-treated film and make considerable savings in label manufacture. In this leading edge process, ANDANTEX USA offers solutions marketed by MEROBEL (REDEX ANDANTEX group), a world leader in the web tension control field.
Francois Bayzelon, President and CEO at ETI, explains. “Our technology offers printers the possibility of entirely manufacturing their self-adhesive labels while making 30 to 70% cost savings on the raw material cost price.” Savings are large scale, the investment payback is in less than one year and the outcome is a natural success. The first COHESIO system was presented at LabelExpo in 2000. Since then, more than 70 lines have been sold at a rate increasing each year with about 20 in 2008 alone. Read the rest of this entry »
