Abstract An apparatus is disclosed for successively affixing labels to packages. The labels are successively fed between an adhesive applying roller and a pressure roller. A coating roller is immerged within a reservoir of adhesive and means are provided to rotationally drive the coating roller to coat the periphery of the adhesive applying roller with adhesive. The pressure roller and the coating roller are each mounted for movement away from the adhesive applying roller in response to a command signal representative of a condition wherein the particular package to which a label is to be affixed is missing. Means are also provided for temporarily stopping the feeding of labels in response to the command signal.
An apparatus according to claim 1; wherein said label supply means includes means responsive to said command signal for rendering said label supply means ineffective.
Claim 2
Dependent Claim
70 words
An apparatus according to claim 1; wherein said label supply means includes a movably mounted label-supporting surface movable in timed relationship with rotational movement of said adhesive applying roller to cyclically advance individual labels towards said adhesive applying roller; pneumatic means for pneumatically holding individual labels against said label-supporting surface during advancement thereof; and movable valve means operative in response to said command signal for rendering said pneumatic means ineffective.
Claim 3
Dependent Claim
34 words
An apparatus according to claim 3; including cam means operative in timed relationship with rotational movement of said adhesive applying roller for cyclically moving said valve means to render said pneumatic means cyclically effective.
Claim 4
Dependent Claim
57 words
An apparatus according to claim 1; wherein said adhesive supply means comprises means defining a reservoir of adhesive; a rotatably mounted roller at least partially immerged in said reservoir and normally in contact with said adhesive applying roller; and means mounting said roller for movement away from said adhesive applying roller in response to said command signal.
Claim 5
Dependent Claim
70 words
An apparatus according to claim 5; wherein said label supply means includes a movable mounted label-supporting surface movable in timed relationship with rotational movement of said adhesive applying roller to cyclically advance individual labels towards said adhesive applying roller; pneumatic means for pneumatically holding individual labels against said label-supporting surface during advancement thereof; and movable valve means operative in response to said command signal for rendering said pneumatic means ineffective.
