A printer system for printing upon labels mounted on a web of release material, includes a stationary reel support upon which a supply reel and a take up reel are mounted for free rotation thereon. A printer is mounted adjacent a supply path extending from the supply reel to the take up reel, and a web drive arrangement is provided for engaging the web and transporting the web past the printer. A reel actuating arrangement, such as an inertial arm, is provided for applying a web unreeling force to the web of material adjacent the supply roll, which force is dependent upon and varies with the radius of the supply roll. A clutch is interposed between the supply reel and the take up reel for rotating the take up reel as the web is unreeled from the supply roll mounted on the supply reel such that substantially the same amount of web of release material is wound onto a take up roll on the take up reel as is unreeled from the supply roll.

A printer system for printing upon labels having pressure sensitive adhesive on the reverse side thereof, said labels being mounted on a web of release material, and for thereafter removing said labels from said web, comprising: stationary reel support means including a stationary support shaft, a supply reel, mounted for free rotation on said reel support means, for supporting a supply roll of said release material having labels mounted thereon, said supply reel including a central hub including hub bearing means for providing free rotation of said supply reel about said stationary support shaft, a take up reel, mounted for free rotation on said reel support means, for supporting a take up roll of said release material wound thereon, said web of release material extending along a supply path from said supply roll to said take up roll, a printer, mounted adjacent said supply path, for printing on said labels, web drive means, mounted adjacent said supply path between said printer and said taken up roll, for engaging said web and unreeling said web from said supply roll, knife edge means, positioned between said printer and said web drive means, for defining a sharp bend in said web supply path to release said labels from said web as said web moves around said sharp bend, and clutch means, interposed between said supply reel and said take up reel, for rotating said take up reel and said take up roll mounted thereon as said web is unreeled from said supply roll such that substantially the same length of said web of release material is wound onto said take up roll as is unreeled from said supply roll, said clutch means including a clutch hub mounted for free rotation on said stationary support shaft, clutch spring means, mounted on said stationary support shaft, for urging said clutch hub into contact with said central hub of said supply reel such that said clutch hub frictionally engages said central hub, and means for attaching said take up reel to said clutch hub, whereby relative rotational movement between said supply reel and said take up reel may be obtained when a torque is applied to said supply reel which is sufficient to overcome the frictional force between said central hub of said supply reel and said clutch hub of said clutch means.
