Products Specs

Plain Wove Dandy Rolls

Construction of the Dandy roll will be with helically coiled rings with suitable gauge diagonally passing rods and flat bars for ease of grinding the body, with suitable end castings.


    Plain Wove Dandy Rolls
  • » Spindle type Dandy rolls for slow speed machines in SS or PB with 35 mesh PB or SS covers.
  • » Hollow type Dandy rolls for medium speed machines in SS or PB with 10 mesh bottom cover and 35 mesh top cover OR only 35 mesh top cover as per needs of the paper mills.
  • » Dandy rolls for high speed machines with Double side flanges, journals and spherical roller bearings, with 10 mesh bottom and 35 mesh top cover.

 

Plate Laid Dandy Rolls

Plate Laid Dandy Rolls The construction pattern of this Dandy roll is totally different from that of a Plain wove or a Chain Laid Dandy. The body of the Dandy Roll is made from independently circled hollow type rings from 0.3 to 0,5 mm thick sheets as per the diameter of the Roll with end casting as per paper mills design. At a distance of approximately 0.3 mm from the periphery of the rings mini diameter holes from 0.45 to 0.7 mm are drilled and laid wires of 0.35 to 0.6 mm are passed through each and every ring and then soldered in position. The body rings are then evenly filed and polished to achieve uniform height. These Dandy rolls also are exclusively used for manufacture of Ledger or laid papers.

Oscillation of water shower is with the help of pneumatic motor or Electro mechanical system.

Dandy Rolls India recommends a water pressure of 6 to 8 Kgs./ sq.cm. The external Save all tray is of Fiber glass or SS. The tray is supplied with steam heated SS jacket to collect and evaporate droplets of water falling from the tray

  • » 35 mesh covers are supplied in SS or PB. They are either mounted on the dandy roll on request or supplied
          as spare covers.

  • » We also supply watermarked spare covers to fix on the dandy roll at the client's site

Watermarks & Embossed Covers

Watermarks & Embossed Covers Watermarks are impressions left on the running sheet of wet paper due to displacement of fibres by the electrotypes or embossed logos fixed on the dandy roll. Dandy Rolls India has pioneered watermarking technology in India. We are proud to note that every member of our watermarking department is a craftsperson who fully understands the nuances of paper making and designs the watermark in consultation with paper makers according to their customized requirements. Care is taken to meet the needs of different machine speeds, different stock conditions and different GSM of paper.
