Reduction in the “Edge Cutter” Waste by Adjustment of “Deckle Guard”


When the paper moves from Head box to wire section, generally, the required width of paper on Pop Reel and Rewinder is 106 inches (269.24 cm). This case study depicts how adjustment of “Deckle Guard” would result in reduction of the “Edge Cutter” (edge trim) waste.

Implementing Industry

Vaibhav Paper Boards Private Limited is a medium scale manufacturer of kraft paper located in Vapi Industrial Estate. Industry was established in 1996, with present production Capacity of 70 TPD and an Annual Turnover of Rs. 50 crores.

Implemented technology / technique


  • When the paper is passed through the wire section for dewatering, total width of wire section is more than required width of the paper, thus, “Deckle Guard” is adjusted to 5.5 inch width from both ends of the wire. 

  • Due to this adjustment, when the paper is cut through the “Edge Cutter” for getting the desired width (106 inches or 269.24 cm), wet broke is generated which is required to be reprocessed through the drum thickener via Couch Pit. This reprocessing increases production cost and resource consumption.


  • Industry after evaluation, readjusted the “Deckle Guard” by reducing the width from 5.5 inches to 3 inches at both the ends of wire section. 

  • The waste from the “Edge Cutter” was reduced to about 2.5%-3%. Which in turn reduced the reprocessing cost i.e., about 9 Rs./kg. 

Economic benefits

With no capital cost investment the industry saved Rs. 5,10,300 per annum in the reprocessing of broke.
