A method and apparatus are provided for maintaining the edge of a moving web on a web handling apparatus at a desired operating path. The operating path of a web edge is monitored with respect to a first desired edge path. The web is secured for movement along an intended path of travel. The web edge is maintained at the first desired edge path. The web edge is monitored with respect to a second desired edge path as it is maintained on the first desired edge path. The web is automatically maintained along the second desired edge path.

Apparatus and method for controlling moving material and the like

An improved apparatus for handling a moving material of indeterminate length utilizes a pair of endless elements located on opposite sides of an intended path of travel for the moving material. Each element is configured to engage and hold a corresponding edge of the material at least partially through the apparatus. The apparatus includes a detector assembly adjacent the path of travel for detecting deviation of at least one edge of the moving material from a normal operating path and outputting signals to initiate corrective reaction to the deviation. The reaction is defined in a predetermined relationship to time the edge remains out of its normal operating path. The apparatus also includes an adjustment device in operative communication with at least one frame member and the detector assembly. The adjustment device receives the corrective signals and positionally adjusts the corresponding frame member in response thereto to achieve the normal operating path. The apparatus may be configured to adjust the frame member at an emergency reaction upon gross deviation of the edge from the normal operating path.

Apparatus and method for securing a moving fabric

Apparatus for controlling the lateral position of a web moving along a path of travel across a scroll roll or other roll capable of imparting lateral movement to the web. The apparatus includes sensors to detect lateral position of the web and elements, preferably conical brushes, which are movable into and out of contact with the web to cause the roll when in contact to move the web in a corrective lateral direction. A mechanism is employed for imparting movement to the web contacting elements which will achieve impact of the elements against the web at a velocity approaching zero. Further, the web contacting element is adapted for pivotal movement away from the web upon contact with the web, thus permitting webs of differing thickness across a normal thickness range to be controlled without additional adjustment to the apparatus.

Apparatus for controlling a web

A winder for textile fabrics or other web materials including a frame having spaced apart support arms pivotally secured thereto. Each support arm has a core holding chuck at the outer end of same, at least one of which is torque driven. A surface drive roll is located on the frame to receive material and apply same to the roll of material being produced. A load cell associated with the surface drive roll measures nip pressure at the interface between the surface drive roll and the roll being formed and is associated with a pneumatic bellows or the like via a control system to cause movement of the support arm for maintenance of a predetermined nip pressure at the drive roll interface. The chucks for holding winding cores include a plurality of arms pivotally secured within a chuck housing which are pivotally movable to an extended core engaging position.
