Apparatus for Dispensing Pressure Sensitive Adhesive Labels onto a Substrate

摘要

A labeling apparatus comprises a separation member configured to promote detachment of an adhesive label from liner web. Adhesive labels are fed to the separation member such that a surface of the facestock contacts the separation member. The separation member has a surface exhibiting a tack such that the tack force between the facestock and the separation member is greater than the release force between the release liner and the adhesive layer of the labels. The labels become associated with the separation member, and the label is applied to a surface of a substrate by contacting the exposed adhesive layer with a surface of a substrate, which causes the adhesive label to detach from the separation member.

主权项

1. An apparatus for dispensing adhesive labels from a liner web onto a substrate comprising:
a feed roll for housing a roll of label material comprising a plurality of adhesive labels disposed on a release liner; the adhesive labels comprising a facestock having an upper surface and a lower surface, and an adhesive layer disposed adjacent the lower surface of the facestock and in contact with the release liner; a separation member for removing the adhesive labels from the release liner; a nip member disposed adjacent the separation member; and a take-up roll for winding the release liner; wherein the label material is oriented such that the upper surface of the facestock contacts the separation member as the label material is fed through the apparatus, and the separation member has a tackified surface providing a tack force between the upper surface of the facestock and the surface of the separation member that is greater than the release force between the adhesive layer and the release liner, and the tackified surface promotes separation of the adhesive labels from the release liner as the upper surface of the facestock contacts the separation member.
