Abstract
A linerless labeling system which utilizes a transparent or opaque paper or plastic film substrate. The substrate is provided in web roll form and is printed on one side with an image overcoated with an adhesive. The opposite surface has release characteristics. When applied, the web is fed across an anvil plate. A die engages the anvil plate, cuts the label from the web which label is then transferred to the surface of an item such as a plastic container.
Claims11
The method of labeling an article comprising:
- (a) providing a roll of a flexible substrate having opposite surfaces and having pre-printed images at predetermined intervals along the substrate, said substrate being at least partially coated on one surface with an adhesive;
- (b) feeding the substrate from the roll to an application station at a predetermined feed rate;
- (c) positioning the article to be labeled adjacent the application station;
- (d) providing an interchangeable die at the application station having a predetermined shape in the desired shape of the label to be applied to the article and which has an opening extending through the die;
- (e) bringing the die into contact with the substrate generally normal to the substrate against an oppositely positioned generally planar anvil plate by moving said die toward said anvil plate to sever a label of predetermined shape from said substrate;
- (f) bringing a transfer member into contact with the severed label and applying and maintaining a predetermined vacuum on the transfer member to retain the severed label thereon;
- (g) extending the transfer member through openings in the die and anvil to bring the severed label into contact with the article with the adhesive surface of the label against the article;
- and
- (h) thereafter releasing the vacuum and withdrawing the transfer member leaving the label affixed to the article.
An applicator apparatus for applying labels to articles which labels are provided on a web which is moved sequentially past an application station comprising:
- (a) feeding means for feeding a web having opposite surfaces and having labels repetitively printed on a surface thereof and having an adhesive on the other surface thereof, said web being provided with registration indicia;
- (b) a die having a cutting edge of a predetermined shape and defining an opening therethrough, said die being interchangeably mounted on a clamping plate;
- (c) an anvil plate having a generally planar surface positioned adjacent said die and defining an opening receiving a retractable and an extendable transfer member aligned with said opening;
- (d) means for selectively moving said die toward said anvil plate into contact generally normal to the web to sever a selected label from said web;
- (e) means for selectively applying a vacuum to said transfer member;
- (f) sensing means for advancing said web at an intermittent predetermined rate whereby a label is severed by said die and the label transferred to the surface of an article by extending said transfer member through said die and said opening in said anvil;
- and
- (g) means for releasing said vacuum when said label is applied to the article.
