Reduction in the “Edge Cutter” Waste by Adjustment of “Deckle Guard”-2

Description

When the paper moves from Head box to wire section, generally, the required width of paper on Pop Reel and Rewinder is 102 inches (259.08 cm). This case study depicts how adjustment of “Deckle Guard” would result in reduction of the “Edge Cutter” (edge trim) waste.

Implementing Industry

R. A. Shaikh Paper Mills Pvt Ltd., located in Vapi Industrial Estate, is a small scale manufacturer of Machine grade kraft paper. Industry was established in 1997, with present production Capacity of 80 TPD and an Annual Turnover of 40 crores.

Implemented technology / technique

BEFORE:

  • 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 get a final width of 102 inches 

  • Due to this adjustment, when the paper is cut through the “Edge Cutter” for getting the desired width, there is generation of wet broke which is required to be reprocessed through the drum thickener via Couch Pit. This reprocessing increases production cost and resource consumption.

AFTER:

  • Industry after evaluation, readjusted the “Deckle Guard” by reducing the total width from 105 inches to 102 inches. 

  • The waste from the “Edge Cutter” was reduced to about 2%-2.4%. Which in turn reduced the reprocessing cost i.e., about 7.5 Rs./kg. 

Economic benefits

With no capital cost investment the industry saved Rs. 24,75,000 per annum in the reprocessing of broke.
