Abstract
A weaving detector for detecting weaving defects generated on the surface of a ground fabric of a carpet or rug moving in a first direction is disclosed. The weaving detector moves in the direction of the width of the cloth and includes one or more detecting sensors spaced in the direction of the movement of the cloth. A guide sled is connected to the sensors and has upwardly curved ends so as to prevent the catching of a defect by the sled. The sensors only provide a defect signal when both sensors simultaneously detect a defect. The sensors are supported by upper and lower supports having vibration absorbing springs therebetween so that the electrical controls are not damaged by the vibrations.
