Abstract
Disclosed herein a web-treating system equipped with web-threading apparatus having as principal structure, pulleys in endwise coaxial relation with web-conveying rolls, an endless drive cable extending over the pulleys, and a web-tail gripping device with transversely elongate elements thereof supported in the web path by the drive cable. Such elements and the pulleys are especially constructed to engage in an interlock condition as the elements traverse portions of the web path around the rolls so as to prevent the elements from centrifugally swinging away from the web path.
