Pneumatic Roll Stand Brakes

Pneumatic brakes (friction brakes) help to control tension for roll stand unwinding.


Double E supplies Re "Combiflex" and "Extreme" brakes.


Ideal for corrugators, paper sheeters, and any other converting machines.

Re pneumatic brakes (friction brakes) run cool on unwind stands so brake pads last far longer than other brake pads.


  • Both models maximize air flow to keep brake cool and extend pad life.
  • Modular caliper design allows appropriate brake force.
  • Long brake pad life.
  • Easy brake pad replacement.
  • Field-proven brakes for low tension to high tension applications.
  • No squealing.
"Extreme" XT.10 Friction Brake

Important characteristics of Extreme brakes


The next generation roll stand brake delivers incredible performance in a clean, safe, compact package. 

  • Unheard Of Pad Life - Extreme brake pads can double the life expectancy of advertised alternatives.
  • Astounding Heat Dissipation - flexible design ensures appropriate heat dissipation at low speeds and light tension or at extremely fast speeds and high tension.
  • Faster speeds, wider webs, thicker materials, higher tension levels
  • At less than 12” in diameter and 5.5” in width, the Extreme easily retrofits any roll stand.
"Combiflex" CX.200, CX.250, CX.300, CX.400 Brakes

Important characteristics of Combiflex brakes


Modular caliper design and unique turbine rotor reduce brake size & cost.


  • Excellent heat dissipation and high quality kevlar pads lengthen pad life.
  • Brakes run cool, minimizing squealing and brake dust.
  • Self-enclosed – safe without a cage.

Easy retrofits and any roll stand


Combiflex brakes easily retrofit Martin and Langston roll stands. They are standard on major OEM machinery around the world including Powell Engineering, BHS, Agnati, Favalessa, Pemco, Torres, and others.

HP-Pack Fan Kit

Fan kit upgrade for Combiflex pneumatic brakes


The HP-pack fan kit is an upgrade for Re CX.250 standard brakes. It is available for existing brakes already in service, as well as on new Combiflex brakes.

  • Provides even greater cooling capacity.

  • More accurate slipping torque.

  • Easy bolt-on installation.

Components of CX brakes

Components of Combiflex pneumatic roll stand brakes

  1. Modular brake design allows calipers to be added or removed to suit each application for customized tension control.
  2. Special turbine brake rotor increases air flow through the brake, reduces heat, and extends brake pad life.
  3. Internal fan provides further cooling; keeps brake cool even at slow speeds.
  4. High performance brake pads last longer while reducing noise and dust.

Combiflex Brakes - Synopsis


The primary function of brakes is to convert mechanical energy into heat, which is then dissipated into the atmosphere. Traditional air-cooled disc brakes are actually very poor heat exchangers, depending largely on a high rotational speed, a large disc diameter, and a large radiant surface to dissipate heat. Often, these brakes overheat, reducing the brake’s efficiency while increasing noise and dust. To solve this problem, most brake manufacturers simply increase the disc size, creating an unnecessarily large brake.


Combiflex rotors are designed with a bi-directional turbine that increases airflow through the brake, even at slow speeds. This airflow allows the brake to dissipate heat more efficiently than other disc brakes.


Attention to ventilation is carried through to the brake housing as well. Combiflex brake housings use a ventilating hole pattern that permits free circulation of air from the middle of the unit to the edges. A built-in fan increases the heat dissipation even further, and ensures a cool-running brake regardless of the running speed. Because these brakes run cool, they eliminate brake fade, excessive noise (squealing) and brake dust, and premature pad wear.


Combiflex pneumatic brake pads last far longer than other brake pads because of the brake’s efficiency and the proprietary kevlar-based pad material. These advantages have made the Combiflex brake the most popular in Europe. They are standard equipment on 85% of European OEM machinery.


The brake’s modular caliper design allows flexibility with the number of calipers used (for improved tension control and/or to allow emergency stopping ability). Unneeded braking power is eliminated, and all customers get brakes that are optimized for their application.


It’s easy to upgrade and roll stand to Combiflex brakes. Most often Re brakes are smaller than existing pneumatic brakes, and the basic model is appropriate and simple to install. Standard rollstand-specific models also exist for Langston, Martin, and other common unwind stands.
