Modern Bracket Systems

In order to maximize the efficiency of the dandy roll, it is necessary to run it on a modern system that can ensure a smooth and vibration free operation with minimum down time; Dandy Rolls India has designed precisely such a system, an elegant solution that has simplified paper production for our clients worldwide.

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.

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.
