Troubleshooting Your Conveyor Belt

Lacing Ripping Off

Belt Tearing Right Behind Bullnose

Splice Marking Product or wearing on Pulleys

Belt Won't Track

Product sticking to Belt

Belt Lacing Ripping Off
	Cause:	Improper break in procedure and over tensioning.
	Solution:	Reduce tension and check squareness of belt and follow proper break in procedure.
Belt Tearing Right Behind Bullnose
	Cause:	Too rigid of a splice for pulley diameter .
	Solution:	Reduced bullnose or different splice (i.e softseal splice reinforced with kevlar).
Splice Marking Product or wearing on Pulleys
	Cause:	Soft product and natural wear and tear.
	Solution:	Flapover lacing (Top, bottom, or both).
Belt Won't Track
	Cause:	Machine or belt misalignment.
	Solution:	Determine whether it is machine or belt. If belt is tracking to right or left flip belt over so that the bottom of the belt is now the top of the belt. If the belt tracks off to the same side, the machine is misaligned. If it tracks off to the other side, the belt is out of square. Realign the machine, have a new belt made, or install a tracking device. Most likely the belt was over tightened during installation.
Product sticking to Belt

	Cause:	Too high of a temperature, cure cycle not long enough, not enough ptfe on the belt to perform adequately.
	Solution:	Reduce the temperature and travel speed or replace the belt.
