DiloTemafa has introduced versions of the Baltromix bale opener and the card willow which are particularly suited to the processing of longer fibres at 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 (VRS-P) 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. The distribution over the working width is controlled by additional flaps. This feeder can be adapted for medium/fine to coarse and medium to long staple fibers.
The “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 horizontal crosslapper version “DLSC” which allows web infeed speeds up to 200 m/min depending on fiber specification. Such infeed speeds will prevent the lapper being the line bottleneck. The DLSC works in conjunction with the proven CV1A web regulation system for improved felt evenness and the potential for fiber savings. A further increase of the drive power within the three-apron-layering technology as well as the application of carbon fiber reinforced parts enables these major improvements. A web guiding system (“extended web guide”) can be added to avoid web wrinkles at lapper reversals.
