Deburring, also known as vegetable matter removal, or VM removal, is a process in textile yarn manufacturing for extracting burrs, seeds and vegetable matter from fibers.
A burr beater attachment, which we also call a VM remover, is added to our dehairer machine to create a system that efficiently removes both undesired heavy guard hair fibers and vm.
The burrs and seeds are removed on impact with the sharp blades of a high speed roller, called a morel roller, which is mounted on a one-meter wide dehairing machine.
Ramella has created a compact VM Remover suitable for small production mills.
Fiber is fed from a conveyor into a 3-cylinder input unit that opens the fibers as they are passed onto the first separation cylinder.
In the central part the two high-speed cylinders separate the coarse hairs from the finer fibers.
Then a roller with sharp blades (burr beater) expels the vegetable matter from the fibers. At the machine exit a doffer roller and fly comb detach the web from the rollers.
The processed fibers are then carried through a transparent plastic tube by means of a centrifugal fan, and the material is blown into a ventilated big bag that can be easily removed from the storage room.
In the lower part of the VM remover there is a second conveyor that collects all of the impurities and the guard hairs and deposits them in a waste collector at the front of the machine.
The Ramella VM Remover has a pair of high-speed rotating cylinders that expel the heavier fibers by means of centrifugal force coupled with differential binding coefficients of the heavy and fine fibers with respect to the rigid card clothing covering the cylinders.
All of the fibers are automatically deposited into easily removable containers without the need for manual collection.
The desired fine fibers are collected at the rear of the machine, directed to the collection container by adjustable air hoses and a stainless steel chute, while the heavy fibers and guard hairs are diverted to a separate collection area under the feed conveyor.
Burr beaters are the principal means by which vegetable matter is removed from wool.
A roller with a special wire (morel roller) transports the fibers, and a second roller expels the vegetable matter by hitting burrs and seeds with sharp blades.
The clearance between these two rollers is adjustable with high precision, and the blades are machined to ensure sharp edges.
The entire roller is protected with an external cover to avoid dirt and dust contaminating the environment.
An automatic cleaning system allows the removal of the vegetable matter from the container without the need to stop the machine.
The VM Remover is equipped with an aluminum-framed fiber collection room with a large access door and transparent walls on all sides. Coupled with the clear plastic tube input, this allows complete visibility of the fibers throughout the process.
The fibers are directly collected in a big bag (100 x 100 cm, H = 100 cm equal to 40" x 40", H = 40") and are immediately ready for further processing.
All big bags are constructed with a fine mesh fabric to allow both fiber ventilation and dust removal.
Insertion of the bags into the collection chamber is quick and easy. Furthermore, each bag has a simple top closure, allowing the fiber to be stored in the bag until ready for further processing.
The Ramella VM Remover was designed specifically for small production mills that often process many different types of fiber.
During our tests, we have successfully dehaired and deburred cashmere, alpaca, buffalo, llama, yak, and qiviut.
The number of passes required to produce an optimal product are dependent on the type of fiber being dehaired.
The VM Remover is driven by 4 independent motors that are electronically controlled by inverters.
With the simple twist of a dial, the user can easily change the relative speeds of the cylinders depending on the type of fiber being processed.
The electronic controllers are contained in a panel with filtered ventilation to protect the sensitive electronic parts.
The control dials are easily accessed on the outside of the panel and every parameter can be easily adjusted on a large touchscreen.
Button panels located on both sides of the VM remover allow simple starting and stopping of the machine at both the entry and the exit.
For maximum safety, our VM remover is fully enclosed by an external frame made of anodized aluminum, which is lightweight, yet sturdy, and resists corrosion.
The protective doors are hinged so they can be quickly and easily opened for cleaning and maintenance.
Two automatic safety devices prohibit the doors from being opened while the machine is running.
The safety structure protects the worker while allowing a wide view and the complete control of the VM remover during the process.

As previously noted the deburring process shares some aspects to the carding process.
Building on our extensive experience in carding machines, the Ramella VM remover has been designed with similar quality characteristics:
• An extremely solid and stable structure, made to last.
• The components are machined for maximum precision and quality.
• The cylinders are driven independently by 4 motors with electronic speed control.
• The rigid card clothing is durable and allows quick cleaning after each run.
• All cylinders are mounted on sealed ball bearings without bushings.
• A modern design specifically created to meet the needs of small production mills and laboratories.
As with the carder, the solid steel structure and the precision of the mechanical parts are critical factors in determining the quality of the VM remover.
The Ramella VM remover is characterized by a 4 cm (1.6'') thick, fully machined steel frame connected by solid steel crossbeams. This structure is approximately 10 times stronger than one formed from welded tubes.
Furthermore, all of the rotating parts are precisely machined and are equipped with micro adjustment, which permits exact roller positioning at micron distances, but more importantly, once the positioning is set, it does not move, resulting in both a consistent, high quality product and longer machine life.
Built to last, all surfaces are painted or chemically treated to resist corrosion.
Every single detail of the Ramella VM remover has been designed using modern 3D CAD.
All of the components have been designed to obtain a high-performance machine with an excellent quality/price ratio.
Even the electric panel has been designed in order to make the use of the VM remover simple and intuitive.
We use CNC lathes, milling machines and modern laser cutters in the production of the VM remover components that we make in-house.
The steel used is of premium quality and all of the commercial components come from suppliers with well-known brands.
