Benefits of technology

[0008] It is an object of the present invention to provide a web steering system for a process line, in which downstream web steering units provide input regarding a web's running position to the upstream web steering units in order to inhibit a web from traveling excessively off-center downstream in the process line.
[0010] To achieve this, the cascade system includes a feedback signal from a downstream steering unit, which is fed into a controller. The feedback is combined with other data to set the aim point of one or more of upstream steering units, usually to something other than process line center. By electronically linking separate steering units together, the downstream steering units can guide more effectively with a greater range of control.
[0015] With the cascade system in place, the consistent effect of the camber will be noted via feedback from the downstream steering unit, and the upstream steering unit will then guide the web past the line center toward the opposite side from where the cambered web is tracking. The adjustment to the guide point, instead of the line center, would steer the edge of the strip near the roll edge away from the camber direction. Thus, the cascade system can run a strip with twice the camber, or other steering problems, without damage.

Abstract

Disclosed is a steering control system / method for a process line running a web material including at least two steering units, a downstream and an upstream steering unit. At least one controller is in communication with the downstream and upstream steering unit. The downstream steering unit collects downstream data concerning a downstream position of the web material and sends the downstream data to the controller. The upstream steering unit collects upstream data concerning an upstream position of the web material, and sends the upstream data to the controller. The data may be an actual position of the web material or a position of a frame or a roller of the steering unit. The controller utilizes the downstream data to effect a downstream adjustment of the downstream steering unit. The controller utilizes the downstream data and the upstream data to effect an upstream adjustment of the upstream steering unit.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention is directed to steering units on a process line and, more particularly, to linking steering units on a continuous process line running a continuous web material to create a cascading steering control scheme. [0003] 2. Description of Related Art [0004] Referring to FIG. 3, a typical steering unit 910 for a continuous process line 900 directs a continuous web material 912 through the process line 900 by exerting a lateral force on the web 912 through a steering assembly 914 to guide the material flow along a center 916 of the process line 900. [0005] In order to laterally move the steering assembly 914, a measurement of the web 912 in relation to the center 916 of the process line 900 is taken. This measurement provides feedback to the steering unit 910 in order to determine a direction and distance for pivoting or moving the steering assembly 914. [0006] A conventional steering assembly 914 incl...
