Dilo is the leading equipment supplier of complete lines for staple fiber nonwoven fabric production. The most recent machine concepts from DiloGroup companies DiloTemafa, DiloSpinnbau and DiloMachines will be presented at IDEA. The group’s booth will feature a special emphasis on new equipment components which improve product quality and increase line capacity.
DiloTemafa has introduced versions of the Baltromix bale opener and the card willow, which are particularly suited to the processing of longer fibers at the highest throughput. Longer cleaning intervals and shorter cleaning times also result from the design changes. The DON dosing opener remains as an intermediate between fiber preparation and the card feeder and provides a fine opening stage.
DiloSpinnbau has a new ‘Unifeed’ card feeder which combines the principle of volumetric charged feeding with the characteristics of a chute feeder but without the conventional overhead trunk which allows for lower ceiling height requirement. The fiber flock matt is condensed by a vacuum delivery apron to give better uniformity of mass distribution. Additional flaps control this over the working width. This feeder can be adapted for medium/fine to coarse and medium to long staple fibers.
The newly developed card ‘VectorQuadroCard’ incorporates a modular transfer group between breast and main section. The quick change facility of this roller group provides different carding options. The delivery system is also flexible to provide parallel laid, random or condensed web. The preopener section on this card has four worker/stripper pairs with five pairs on the main cylinder. Emphasis is on high throughput with good web quality.
DiloMachines has a new DLSC horizontal crosslapper version which allows electro-mechanical web infeed speeds up to 200 m/min depending on fiber specification. Such infeed speeds will prevent the lapper being the line bottleneck. This lapper works in conjunction with the proven CV1A web regulation system for improved felt evenness and the potential for fiber savings. This very high web infeed speed has been made possible by a further increase in the drive power within the three apron layering technology. A web guiding system (“extended web guide”) can be added to avoid web wrinkles at lapper reversals.
The automatic turret unwinder TUW Series offers a quick-change function which means that a new roll begins automatically when the previous one is finished. Thus, producing lines never stop. The nonstop process aims to unwind the reel without stopping the downstream coating or laminating process of the line. During the unwinding process, a new roll can be loaded in hidden time thanks to roll down end and dedicated cartridge. Moreover, the TUW Series ensures a constant speed to maintain tension in the line process. Specially engineered to improve process performance, the TUW Series ensures to users easy installation, easy handling and durability.
