Abstract
Abstract A label applicator is disclosed for receiving pressure-sensitive labels which have been peeled from a backing strip and for applying the labels to a desired surface. The tendency of the labels to bunch or wrinkle as they are delivered to the applicator face is avoided by causing the labels to bow or curve outward slightly from the plane of the face plate, with the bowing or curvature occurring across the width of the label in a direction transverse to the feed direction. The bowing increases the longitudinal stiffness of the label in the feed direction, and allows the label to be pushed across the applicator face without bunching or wrinkling even when relatively long and narrow labels are employed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
91 words
An apparatus for receiving and applying labels, comprising: an enclosure having a generally planar face plate formed with a plurality of openings therein communicating with the interior of the enclosure; means for maintaining a partial vacuum within said enclosure in order to cause a label to adhere to the outside of the face plate; means for causing the label to transfer from the face plate to a label receiving surface; and means on said face plate for causing the adhered label to bow outward from the plane of the face plate.
Claim 2
Independent Claim
91 words
An apparatus for receiving and applying labels, comprising: an enclosure having a generally planar face plate formed with a plurality of openings therein communicating with the interior of the enclosure; means for maintaining a partial vacuum within said enclosure in order to cause a label to adhere to the outside of the face plate; means for causing the label to transfer from the face plate to a label receiving surface; and means on said face plate for causing the adhered label to bow outward from the plane of the face plate.
Claim 3
Dependent Claim
96 words
An apparatus as claimed in claim 1, wherein: said face plate is formed with a plurality of raised parallel bars which are spaced apart from each other to define a grid-like label supporting surface; and said openings are formed in the area of the face plate between adjacent ones of said bars; and said means for causing the label to bow outward from the plane of the face plate comprises at least one of said bars which is raised outward from the plane of the face plate by a distance greater than others of said bars.
Claim 4
Dependent Claim
28 words
An apparatus as claimed in claim 1, wherein said means for maintaining a partial vacuum within the enclosure comprises a fan for continuously exhausting air from said enclosure.
Claim 5
Dependent Claim
59 words
An apparatus as claimed in claim 1, wherein said means for causing the label to transfer from the face plate to a label receiving surface comprises means for applying a burst of positive air pressure to the label sufficient to overcome the adherence of the label to the face plate and to propel the label toward the receiving surface.
Claim 6
Dependent Claim
55 words
An apparatus as claimed in claim 4, wherein said means for applying a burst of positive air pressure to the label comprises: an air manifold adapted to be connected to a source of compressed air; and a plurality of conduits connected between said air manifold and selected ones of the openings in said face plate.
Claim 7
Dependent Claim
34 words
An apparatus as claimed in claim 5, wherein said conduits comprise flexible tubes releasably connected to the selected openings in the face plate, all of said flexible tubes being of approximately the same length.
