Abstract

An apparatus for and method of applying heat transferable labels from a web onto a hollow article. The articles to be decorated pass through the apparatus continuously with the label being applied without any stoppage or other intermittent motion imparted to the article being decorated. In this respect, the articles are conveyed to a receptacle holding means which receives and holds the article while passing through the decorating station. The label carrying web, which is driven through the decorating station, is heated both at and prior to the decorating station to facilitate transfer without the necessity of interrupting either the movement of the label carrying web or article to be decorated.

Claims

1. A system for feeding a label carrying web to a decorating station for application onto an article to be decorated which comprises:

a web supply reel;

a web take up reel;

braking means engaging said web supply reel

a movable roller disposed in the path of said label carrying web between said supply reel and decorating station;

switching means operatively connected to said braking means so as to regulate the tension of the label carrying web being dispensed from said supply reel;

means coupled to said movable roller disposed so as to activate said switching means when said roller moves to a predetermined position and modify the braking force applied to said web supply reel; and

biasing means urging said movable roller to apply tension to said label carrying web being fed from said web supply wheel.

2. A system in accordance with claim 1 wherein said means coupled to said movable roller comprises an arm member having one end thereof pivotally mounted and the other end thereof connected to said biasing means.

3. A system in accordance with claim 2 wherein said other end of said arm member is disposed over said switching means.

4. A system in accordance with claim 1 which further includes:

clutch means engaging said web take up reel;

a movable roller disposed in the path of said label carrying web between said take up reel and decorating station;

switching means operatively connected to said clutch means so as to regulate the tension of the label carrying web being fed to said take up reel;

an arm member connected to said movable roller disposed so as to activate said switching means when said roller moves to a predetermined position and modify the amount of clutch slippage being applied to said take up reel; and

biasing means urging said movable roller to apply tension to said label carrying web being fed to said take up reel.

5. A system in accordance with claim 4 wherein said arm member is pivotally mounted at one end thereof and said biasing means is connected to the other end thereof.

6. A system in accordance with claim 4 wherein said other end of said arm member is disposed over said switching means.

7. A system in accordance with claim 1 which further includes a slidably movable roller disposed in the path of and in engagement with said label carrying web between said web supply reel and said web take up reel, and means for moving said slidably movable roller thereby advancing or retracting the positioning of the label carrying web at the decorating station.
