Abstract

A system and method for transporting an adhesive side of a sheet media, particularly a sheet media having an adhesive side with an encapsulated adhesive ruptured by an activator unit. This activation unit can include one or more of the following: a pressure roller, a pair of pressure rollers, an activator blade, a set of rotatable discs or a series of sets of rotatable discs. A sheet media having an encapsulated adhesive is fed past the activator unit in the system and method, whereby the capsules will be ruptured and the adhesive side of the sheet media is activated. A release liner device such as a belt or roll of releasable sheet media transports the activated sheet media throughout subsequent process steps, e.g. label printing, cutting, die casting, etc.

transporting the sheet media to a subsequent process step with said release liner device.

2. The method according to claim 1, wherein said release liner device is an endless belt.

3. The method as recited in claim 1, further comprising the step of printing indicia on the sheet media.

4. The method as recited in claim 1, further comprising the step of using sheet media with indicia printed on at least one surface thereof.

5. A method for transporting a sheet media having an at least one adhesive side, comprising the steps of:

providing a sheet media having the at least one adhesive side;

feeding the sheet media along a travel path;

passing the sheet media against an activation device;

rupturing the encapsulated adhesive as the sheet media moves past the activation device;

laminating the at least one adhesive side of the sheet media with a release liner device; and

transporting the sheet media to a subsequent process step with said release liner device, wherein said release liner device is a roll of releasable sheet media.

6. A method for transporting a sheet media having an at least one adhesive side, comprising the steps of:

providing a sheet media having the at least one adhesive side;

feeding the sheet media along a travel path;

passing the sheet media against an activation device;

rupturing the encapsulated adhesive as the sheet media moves past the activation device;

laminating the at least one adhesive side of the sheet media with a release liner device; and

transporting the sheet media to a subsequent process step with said release liner device, wherein the activation device includes an activator blade and wherein the method further comprises the step of spreading the adhesive after rupture thereof with the activator blade.

7. The method according to claim 6, wherein the activation device further comprises at least one crushing roller, the crushing roller being located upstream from the activator blade and wherein the method further comprises the step of sequentially engaging the sheet media with the at least one crushing roller and the activator blade.

8. The method according to claim 7, wherein the step of feeding the sheet media moves the sheet media at a first speed and the method further comprises the step of moving the at least one crushing roller at a second speed, the first speed being different from the second speed.

9. The method as recited in claim 6, wherein the activation device includes at least one crushing roller, the method further comprises the step of rotating the at least one crushing roller about an axis.

10. A system for handling an adhesive coated sheet media, comprising:

a feeder for the sheet media;

an activation device for releasing an encapsulated adhesive with a shearing action as sheet media is moved past the activation device by the feeder; and

a release liner device for laminating with at least one adhesive side of the sheet media and transporting the sheet media through a travel path.

11. The system according to claim 10, further comprising:

a cutter for cutting the sheet media; and

a label applicator, the label applicator being downstream from the cutter.

12. The system according to claim 10, wherein the release liner device is an endless belt.

13. The system according to claim 10, wherein the release liner device includes at least one surface having a releasable, non-stick surface.

14. The system according to claim 10, wherein the travel path includes a process device, said process device including a printer assembly, a die cutting assembly or a label activation assembly in a position opposed to said release liner device, said travel path for said sheet media passing between said process device and said release liner device.

15. A system for handling an adhesive coated sheet media, comprising:

a feeder for the sheet media;

an activation device for releasing an encapsulated adhesive as sheet media is moved past the activation device by the feeder; and

a release liner device for laminating with at least one adhesive side of the sheet media and transporting the sheet media through a travel path, wherein the activation device includes an activator blade adjacent to the travel path, the activator blade being fixed in position relative to the travel path.

16. The system according to claim 15, further comprising a support surface adjacent the activator blade, the travel path passing between the activator blade and the support surface.

17. The system according to claim 15, wherein the support surface is a roller.

18. The system according to claim 15, wherein the activator blade extends across at least half of a widthwise direction of the sheet media.

19. The system as recited in claim 15, wherein the blade is at a fixed angle relative to the travel path.

20. The system as recited in claim 19, wherein the fixed angle is an acute angle between the activator blade and an upstream position of the sheet media.

21. The system as recited in claim 15, further comprising a printer, the printer being located downstream of the activation device and being adjacent to the travel path.

22. The system as recited in claim 15, further comprising a printer, the printer being located upstream of the activation device and being adjacent to the travel path.
