Lightweight and Efficient Expanding Shafts
Our expandable mandrels are easy to install and handle. Designed for seamless integration with your equipment, our custom mandrels operate without special adjustement.
We also offer fiberglass expandable mandrels, ideal for versatile applications with materials such as PVC or cardboard. Additionally, we manufacture and distribute spreaders, sleeves, slat rollers, and other components throughout France and internationally.
Custom Inflatable Bars Made in France
Shafts with Lugs
Preferred solution for high-load and/or high-tension coils. The lugs exert a multi-point force on the core. Each lug hugs and locks the core, any slippage during tensioning.
Appreciated for its rigidity, load-bearing capacity and high strength, the lug bar is available in three materials: aluminum, steel or carbon.
This makes it possible to combine strength and lightweight design !
+ Reinforced core support
+ High tension
+ Easy maintenance
+ Manufactured in carbon, aluminium, reinforced aluminium, and steel
+ MBC patent
Shafts with Continuous Fillets
Perfect for any width of material. Align your coil with your machine, whether winding in single or multiple lanes. The Continuous Fillets securely hold your coil and are available in aluminum or steel with various options.
+ Easy insertion
+ Lightweight design
+ Quick maintenance
+ Suitable for all diameters
Expandable Heads
Expandable heads allow you to work in a cantilevered position. Just like expandable bars, you can find them with Continuous Fillets or Lugs expansion, available in rubber, aluminum or steel.
Is your spindle installed on a machine with a specific inflation system ? No problem, we can offer equipment designed as a direct replacement
+ Cantilever work
+ Single-block steel bar
+ Rigidity - Adaptability
+ Fixed spindle
Paper converting shaft
Specially designed for the paper industry, this bar meets extreme operating conditions. Capable of withstanding loads and speeds specific to paper machines: (1750m/min - 15 tons).
+ Locking and centering bars
+ Static tube balancing
+ Conical bearing housing
+ 1750 m/ min - up to 15 tons
Friction Bars
Friction bars have been designed for multi-track winding. Friction rings allow you to wind each coil with equal tension. When the tension becomes too high, the rings slip, enabling individual tension control for each roll.
+ Multi-track operation
+ Equal tension on each coil
+ Friction ring
Shafts with bearing housings for cantilevered unloading
