SKEWED SLAT CONTROL SYSTEM FOR ARTICLE CONVEYOR

摘要

A skew detection and correction system, and method of correcting skew, in a conveyor system having an endless web that is propelled in a longitudinal direction, includes providing a skew detector and determining if at least some of the cross members of the web are non-perpendicular to the longitudinal direction and providing a differential lubricant application. The lubricant applicator is responsive to the skew detector and applies a relatively greater amount of lubricant to one lateral side of the web than to the other side of the web. This causes the side of the web receiving less lubricant to stretch more than the other side to reduce the difference in the amount of stretch.
