Abstract

A flexible carrier for carrying a plurality of containers within a plurality of corresponding container receiving apertures is formed using a rotary die within a rotary die press resulting in carriers having complex configurations including close tolerance cuts and complex perforation patterns.

First claim

The invention claimed is:

1. An apparatus for producing container carriers comprising:
an unwinder providing a generally continuous sheet of plastic material;
a rotary die including a cylinder and a plate wrapped around the cylinder, the plate having a nested edge, wherein the nested edge comprises a finger on one edge of the plate and a receiving groove on an opposite edge of the plate wherein the finger nests within the receiving groove when the plate is wrapped around the cylinder, wherein the rotary die includes one or more curved blades and is configured to punch the plastic material into a generally continuous string of three or more rows of container carriers;
an outfeed for transferring the generally continuous string to a collection station.

2. The apparatus of claim 1 wherein at least one of the cylinder and the plate are magnetic.

3. The apparatus of claim 1 further comprising a second rotary die including a second cylinder and a second plate.

4. The apparatus of claim 3 wherein the rotary die punches a container carrier and the second rotary die punches an adjacent. container carrier.

5. The apparatus of claim 1 further comprising a printer positioned inline with the rotary die, the printer for printing at least one of color, text or product information on the container carrier.

6. The apparatus of claim 5 wherein the printer does not print on scrap material that is ejected from the generally continuous string of container carriers.

7. The apparatus of claim 1 Wherein the plate is printed from edge to edge.

8. The apparatus of claim 1 wherein the container carriers include a nonlinear perforation.

9. The apparatus of claim 1 further comprising at least one waste module for evacuating scrap from the generally continuous string.

10. The apparatus of claim 1 further comprising a corona treater positioned upstream of the rotary die.
