ABSTRACT:
The disclosure concerns a winding mechanism for a rolled tape-like web, like a composite label or tag web or a carbon ribbon, for eliminating the slackening or meandering of the web. The web is fed from a feed reel to a take-up reel. The take-up reel drives the feed reel to rotate in a first direction by drawing the web off the feed reel. A belt also connects the take-up reel and the feed reel so that rotation of the take-up reel for winding the web onto it is transmitted by the belt to the feed reel to urge the feed reel to rotate in the direction opposite that direction of rotation of the feed reel for feeding the web off the feed reel. This tightens the web, but it is not a sufficient retarding force to prevent feeding of the web. In one embodiment, the belt connection is by a helical coiled spring belt. A spring-operated brake is positioned at the feed reel or at both of the feed and take-up reels for preventing overrunning of these reels.
