Abstract
An apparatus and method for removing matrix material from a web of cut adhesive backed labels. A matrix stripping apparatus comprises a rotating cylinder for receiving a web of cut adhesive labels, a source for applying an electrostatic charge to the web of cut adhesive labels, and a separation member to facilitate separation of the matrix from a web comprising cut labels and a release liner. Applying an electrostatic charge to the web assists in holding the web against the rotating cylinder and relieves tension in the separation and removal of the matrix material.
