DD-Compound GmbH (Ibbenbüren, Germany) introduces its newest patented flexible resin feedline, Roger. Said to satisfy both the controller and technician, the D-shaped, corrugated feedline is designed to provide a homogeneous flow front for long part lengths up to 80 m (such as wind turbine blades).
Easy to place and provided on a roll, Roger minimizes print, similar to flat resin channels. Parts are fed from one center resin inlet which can be placed either in a straight line or on contoured geometries. Holes in the top of the feedline are also said to help complete air evacuation, as opposed to using omega channels. The company uses boat infusion as an example of these benefits, noting a simplified, more reliable process.

In addition to the technical benefits, DD-Compound also notes that Roger costs less per meter and is more environmentally friendly, a result of less material waste.
In the production of wind turbines, Roger reportedly saves around 25 man-hours, or 30 minutes in cycle time compared to standard materials used. This, says the company, is achieved by Roger’s flexible design (rolled out and fixed in place), which saves time placing feedlines. Moreover, the risk of faulty connections of the omega sections is eliminated.
