At ITMA, DiloGroup will exhibit two complete lines to show the broad scope of its portfolio. Dilo will show a staple fibre needling line for the production of technical textiles in wide working width which is especially suitable to produce geotextiles. Fibre preparation from DiloTemafa starts with a bale opener BTDL of the latest design which is suitable for processing longer fibers. The subsequent carding willow KW combines in the preopening stage good preblending and preopening with highest throughput.

It is also designed for processing longer fibres. New design elements allow longer cleaning intervals with reduced cleaning time. The subsequent dosing opener DON feeds the fibers via its fine opening stage to the newly developed card feeder type VRS-P.

The VRS-P feeder combines the principle of volumetric precisely charged feeding, with the characteristics of a vibration chute feeder and eliminates a conventional large trunk (on thetop). This results in a better and more homogeneous distribution of the fibre flocks. Furthermore, a lower ceiling height of the building reduces the costs for the construction of the factory and its operating expenses.

The newly developed card “VectorQuadroCard” incorporates a completely new “modular transfer group” between breast and main section. The flexible and quick change of this “transfer group” makes possible three different card types:
– type VQ-Q with a “Quattro group” to improve web evenness and fibre blending, arranged as
a double transfer between preopener and main cylinder with two doffers and two transfer
rollers to the main cylinder.
– type VQ-V with a top doffer together with a transfer roller and a lower transfer roller to
increase the throughput by using the “doubling effect” between preopener and main cylinder.
– type VQ-T with only one transfer roller between preopener and main cylinder.
The model series VQC uses 4 worker/stripper pairs of rollers on the preopener and five
worker/stripper pairs on the main cylinder. Furthermore, the delivery system is also very flexible and may be combined in different variations:
– with two doffer rollers and respective parallel delivery system
– with pairs of doffer rollers and condenser rolls top and bottom
– as random card with random rollers, doffers, condenser rolls and take-off rollers

The universal model series “VectorQuadroCard” comprises variable components for all kinds of applications. Focus is laid on high throughput with good web quality. The “VQC” that will be displayed at the show with a working width of 3.2 meters is designed for the geotextile sector.

The new crosslapper type “Super-DLSC 200” allows electro-mechanical speeds of up to 200 m/min for web infeed speeds, depending on the fiber specification. It aims at reducing a possible bottleneck for the total throughput of the complete installation. At the crosslapperinfeed Dilo has installed the proven “CV1A” web regulation system for an improved evenness of the needlefelt with a great potential for fiber savings. This very high web infeed speed has been made possible by a further increase of the drive power within the “three-apron-layering technology.” All drives for the aprons and the layering carriages are direct water-cooled torque motors to improve the acceleration with reduced gear wear. In addition, we have taken special measures to eliminate and reduce apron vibrations in order to achieve an exact web overlapping (lap joints). Furthermore, we have installed a “web guiding system” (FLS) to avoid wrinkles for example at the speed change of the upper carriage. The web infeed width is 3.2 meters, the layering width is 7.0 meter.

After the crosslapper, Dilo will show a new needleloom type DI-LOOM OD-II AB with CBF feeding system. When designing this model series, Dilo has laid special emphasis on cost effectiveness in the preneedling machine. The model series DI-LOOM AB has a very
favourable price-performance ratio.
