DREF Friction Spinning Machinery

Stewarts of America manufactures components for Fehrer DREF Friction spinning equipment. Stewarts also offers new and used Fehrer DREF Friction spinning machinery.

Recognizing that there was a need by our customers, Stewarts have developed a solid base of spare parts for Fehrer DREF friction spinning equipment and now offer a wide verity of parts to include both mechanical and electrical components.

Stewarts offers parts to include the perforated spinning cylinders, combing rolls, suction tubes and more for:

• Fehrer DREF 2 (DREF II) (both Gen 1 an Gen 2)
• Fehrer DREF 3 (DREF III)
• Fehrer DREF 2000
• Fehrer DREF 3000
• Other fiction spinning machines

Stewarts of America has modified high wear machine components such as the perforated cylinders, suction tubes and motors to make them work more efficiently, even with tough materials such as fiberglass, Nomex and Kevlar. Working together with our customers worldwide, Stewarts offer a wide array parts and modifications that allow new and unique yarns to be made by this equipment, and to make parts for these machines more accessible.

Fehrer DREF Refurbishing

Stewarts can take an existing Fehrer DREF spinning machine, completely tear it down, and build it back completely refurbished. We offer electrical drive conversions, part upgrades and technical expertise.

Naturally, we are in touch with mills worldwide and are often the first to know about used equipment that comes available to the marketplace. The difference is we know the technical spinning industry. We are also experts in the mop yarn industry, we offer worldwide support and consultation for this field.

We can offer machinery for mop yarn spinning such as the Ingolstadt RU04, RU14 and RL10 machines. We also manufacture Rotor cups, navels / doff tubes, combing rolls and other components for these machines. (See the Open End Spinning Section for more details.)

Waste Opening

Pinned lags - Whether you have a LaRoche, Dell'Orco and Villini, Margasa, Marlasca, Italia Regeneratzione, Temafa, Autefa or other waste opening unit, Stewarts can manufacture pinned lags for your cylinders. We offer standard pin configurations and completely custom configurations for unorthodox applications. Our waste opening pins are designed to penetrate and open fiber effectively but gently, keeping as much staple length as possible. The pins are designed to maximize opening and keep long life, while minimizing friction.

Stewarts of America offers pinned aluminum and wooden lags for all textile recycling machinery.

From interlocking tongue and groove lags, to flat lags with scallops, Stewarts has made pinned lags for the textile industry for over 130 years. We have the designs for all the OEM lags, and specialize in placing custom pin patterns in cylinders to achieve unique opening capabilities. We have worked with tough to open fibers such as carpet, Kevlar and other materials. We can convert opening machinery that currently does not do the job, to super openers!

The Waste opening / textile recycling process is tough on pins. The process can generate lots of heat from friction and sparks from metallic debris that are processed with used clothing and other post-consumer materials. This heat can cause breakdown of the holding capability of the pins in the metallic lag. Solving this problem led Stewarts of America to innovate with our latest technology – The Excalibur™ pins – The pin that will not liberate! Using a clever pin and hole technology combination, we keep the price of the technology low, while utilizing the benefits of a mechanical fit.

Stewarts also uses our pin pattern layout technology to optimize the opening effect on fibers. This makes opening more efficient and generates less friction. All our pinned lags are machined on our state of the art CNC machining centers to ensure precise pin hole placement, pattern and tolerances. Bolt holes are machined at the same time, thus providing highly accurate mounting locations to align with customer's existing cylinders.

Unique Design
The unique design of interlocking aluminum alloy staves have firmly established themselves in the world's fiber industries with its extended life and strength. Over 5 million being supplied to well over 55 countries over the past 80 years and their accuracy and long life are now legendary. Indeed some of the original staves are still running after many re-pinnings. For high density pinning, our staves have now demonstrated their accuracy and reliability over some 25 years.

Interlocking Staves
The interlock between our staves means that the staves in front and behind each stave contribute to the total strength of the assembly, and greatly reduce the chances of a catastrophic damage in a card smash.

Pinned and Wire Mini-Trim Cylinders
Edge trim and mini-trim openers come in a wide verity of widths and diameters. Stewarts covers them all.

Fewer Screw Holes
Fewer retaining screws are needed because of the strength of the aluminum alloy together with the patented interlock. This means less gaps in the pinning, improved carding and easier maintenance. In many cases the staves and lags can be made double width, further reducing the problem. However the screw holes are still placed so that the aluminum staves can be fitted in place of wooden staves without modification.

Here are some of the main advantages:

• Lightweight, high strength aluminum alloy construction
• Interlocking fit; virtually smash proof
• Fewer screw holes; Easier fitting and removal
• Fire Resistant; Unaffected by humidity
• Carbon steel pins give extra long life in aluminum
• Indefinite number of re pinnings possible
• Easy re-pinning with pins
• Double width lags for even easier replacement
• Extra high pin-point density using "N.I.F" pinning
• Field proven for over 60 years in over 50 countries
• Greatly extended life gives excellent value for money

We have the original specifications and drawings for many of these rollers as we are the manufacturer of choice for many textile machinery makers worldwide.

Carding - Chute Feed and Licker/Taker in Rolls and Bars

Stewarts is involved in two areas of the carding machinery. Stewarts manufactures pinned cylinders and bars for chute feed applications and pinned and wire licker ins. Pinned licker ins are sometimes used alone against the main carding cylinder, or may be included in a 3-roller cassette, such as in a Trutzschler cards, where the pinned roller takes the brunt of the primary opening work.

Chute feed rollers come in various configurations:

• Straight pinned bars, extruded shaped, square bar or T bar
