Abstract
An on-line defect detection system for detecting a defect in a fibrous member and related processes are provided. The defect detection system may include first and second fiber contacting members where at least one of the contacting members is shiftable relative to the other contacting member. The defect detection system may also include a defect detection zone defined between at least a portion of the first and second fiber contacting members. The defect detection zone may be configured to receive at least a portion of the fibrous member in a manner such that the fibrous member contacts the first and second fiber contacting members in the defect detection zone. Further, the defect detection zone may also include a sensor configured to sense movement of one of the first and second fiber contacting members and generate an electronic signal based on the sensed movement of the at least one fiber contacting member.
