Abstract
The labeling machine comprises a stationary label hopper, a rotatable turret provided with suction means located adjacent to the leading edge of the terminal label in the article and constructed to enter into the hopper to lift by vacuum the leading edge of the terminal label out of the hopper and then in coaction with a pressure roll to mechanically withdraw the remainder of the label from the hopper and insert such leading label edge into the entry end of a fixed label guideway. Located intermediate the ends of the guideway and clamping the label in the guideway therebetween are a feed roll and a pressure roll spaced from the turret a distance substantially less than the length of the label so that they clamp the label before it moves past the turret and its associated pressure roll. Positioned adjacent to the discharge end of said guideway is a rotatable glue roll onto which the label is directed as it is discharged from said guideway. The turret and its associated pressure roll, the feed roll and its associated pressure roll, and the glue roll each impart to the label during their mechanical feed thereof, a corresponding given linear velocity. Associated with the glue roll are …
