Needle punching lines for Geotextiles

AUTEFA Solutions offers complete lines for the production of needled geotextiles.  Geotextiles are generally flat or three-dimensional textiles.  These nonwovens are used for separation, reinforcement and filtration in the construction of highways, airfields, railways, sports fields, drainage ditches, dams and dykes. Despite their strength and durability, geotextiles are light and easy to lay. They are used as a building material in civil engineering, water engineering and traffic route construction and are an important aid in geotechnical securing work.

Advanced Geotextile Lines

AUTEFA offers complete lines for the production of needlepunched geotextiles. A growing demand in the last years increase the demand to invest in new Geotextile production. According to EDANA, Geosynthetics and Geotextiles present the largest long-life end use segment.

Using AUTEFA Solutions state‐of‐the art technology Geotextile producers are able to adapt to the continually growing market requirements and to react promptly and flexibly to individual customer needs. For the production of Geotextile and Geosynthetics the scope of supply includes complete solution from fiber opening and blending, Double Doffer card, crosslapper Topliner with web profile control WebMax and needle punching machines Stylus NL with winders. All projects are designed to cater the increasing demand of Geotextiles in the national and international markets.

Our technology for your success

AUTEFA Solutions is a leading solution provider for turn-key nonwovens lines and machines for carded- crosslapped needlepunching lines, spunlace lines and thermobonding lines. All process steps base on well-known and worldwide approved technologies. Besides the complete equipment, the company supplies comprehensive engineering services, including start-up and production support, as well as guarantees for quality and capacity.

Line configuration

Machinery and line components

The composition of a blending line, as well as the type and configuration of each machine, is flexible and can vary according to the fibers to be processed and to the final product to be manufactured. Each line is configured on the customer needs, in order to reach the best efficiency required by the process.

The Double Doffer is a typical card composed by a first main cylinder, by a transfer roller and a second main cylinder. It can be fed by different feeding groups, i.e. feeding rollers, overhead feed plates or bottom plates. It has been purposely designed and built to guarantee constant performances and long-term duration to the customer. Moreover, this highly reliable card may be supplied with different delivery groups, like two parallel webs, parallel and condensed webs or two condensed webs, as well.

AUTEFA Solutions WebMax produces a counter weight profile to avoid the smile effect. This is the key to product quality. WebMax ensures that the carded web weight is already being altered at the crosslapper infeed. Via the layering carriage control, the carded web is deposited on the layering belt in a way that the lapped web weight is controllably lighter in the edge areas compared to the center areas. This concave weight profile therefore compensates the weight changes due to material shrinkage and leads to the highest possible weight evenness in the final product.

The crosslappers Topliner increase both web homogeneity and throughput speeds. The crosslappers of the Topliner series, combined with web profile control WebMax and the CLOSED LOOP system prevent the increased weight of the fabric in the edge areas, called the smile effect. This results in an excellent uniformity in the fabric and, thanks to a considerable saving of materials, a reduction in material costs.

The Web Drafter WD will be installed between the crosslapper and the first needleloom. With up to 8 drafting trios, the Web Drafter drafts the crosslapped web in material direction (MD) and enables high infeed speeds as well as precise weight distribution. This results into a web optimization in regards of tensile strength and elongation. When processing lightweight products, the Web Drafter increases the web uniformity.

 

The design of the Needle Loom Stylus is tailored to customers’ requirements in terms of working width, maximum machine load and machine speeds achievable.

More information

AUTEFA Solutions Stylus NL needle looms are highly versatile and offer medium needle densities for pre-needling and ensure enhanced performance through increased penetration density for finish-needling.
