Screw flight manufactured in 1.4301 stainless steel. Unlike traditional sectional flights, ribbon flight has a larger inner diameter and a narrower web. The cross-section of ribbon flight remains consistent from the outer diameter to the inner diameter.
Ribbon flights are also used in agiators and blenders, because the material will flow around the screw blade, when the filling in the machine is increased.
Solutions with ribbon screw flights are often seen when transporting food material during the manufacturing processes. A screw conveyor for transporting food material is a well known solution. The main advantage is that you can make all material in contact with the bulk in stainless steel.
In this case we have indicated the mounting on the screw shaft. Working with this type of screw flights can be a slowly process. Check the time you spend in the work shop. If the screw flight has a proper design and has been pressed well the working time is not longer compared to standard cylindrical screw flights.
BEMA offers screw flights that are easy to mount and weld afterwards. Since we are manufacturing screw augers by ourself, we know the importance to reduce the total time for manufacturing the complete product.

A ribbon screw flight is designed to handle sticky or viscous materials effectively thanks to its open flight design. The openings between the inner and outer diameter allow bulk material to move without constant contact with the screw shaft, making it ideal for food processing, agitators and blenders.
Ribbon flights have a larger inner diameter and a narrower web, giving them a consistent cross‑section and allowing material to flow around the blade when machine filling increases. This reduces buildup and improves flow for challenging materials.
Designing ribbon flights requires engineering expertise to ensure the blank forms correctly into a flight that is easy to mount on the screw shaft. Proper design and pressing are essential to reduce workshop time and ensure smooth assembly.
BEMA manufactures screw augers in‑house and therefore focuses on producing ribbon flights that are easy to mount and weld, helping reduce total production time. Their experience ensures high‑quality stainless‑steel flights suitable for demanding applications.
