1. A device for stacking a sheet of a plurality of partially connected labels into a stack forming a plurality of partially connected pads of labels, the device comprising:
- a robot arm having at least one vacuum source configured to selectively supply a vacuum force;
a plate coupled to the robot arm; and
a flexible pad coupled to the plate and including a plurality of apertures configured to direct the majority of the vacuum force through the flexible pad to a surface of the sheet of the plurality of partially connected labels, the flexible pad including a layer of closed cell foam proximate to the robot arm and a layer of open cell foam distal to the robot arm,wherein the at least one vacuum source is fluidly coupled with two or more of the plurality of apertures.

16. A device for stacking a sheet of a plurality of partially connected labels into a stack forming a plurality of partially connected pads of labels, the device comprising:
-
a robot arm having at least one vacuum source configured to selectively supply a vacuum force, the robot arm coupled to a plurality of struts configured to position the robot arm; a plate coupled to the robot arm; and a flexible pad coupled to the plate and including a plurality of apertures configured to direct the majority of the vacuum force through the flexible pad to a surface of the sheet of the plurality of partially connected labels, the plurality of apertures being directly formed by the flexible pad and void of any additional structure, the flexible pad including a layer of closed cell foam proximate to the robot arm and a layer of open cell foam distal to the robot arm, the layer of open cell foam having a lower density than the layer of closed cell foam, the layer of closed cell foam having a thickness greater than a thickness of the layer of open cell foam, the layer of open cell foam being the most distally extending component of the device, wherein the at least one vacuum source is fluidly coupled with two or more of the plurality of apertures.
