Abstract
A fabric width control system for a fabric compactor for compacting a moving fabric web. The system includes a vision assembly for measuring the width of the moving fabric web downstream of the fabric compactor. A mechanical spreader is located upstream of the fabric compactor for adjusting the width of the web in response to a control signal from an open loop controller. The controller is connected to the vision assembly and the mechanical spreader for controlling the position of the mechanical spreader in response to a change in the width of the moving fabric web from a pre-set value. In the preferred embodiment, a cloth stabilizer is located downstream of the fabric compactor for maintaining the moving fabric web at a pre-determined position with respect to the vision assembly, thereby further increasing the accuracy of the system.
