Claims: What is claimed is:

1. Apparatus for applying labels from a carrier strip having adhesive labels on both sides of the strip, comprising:

means feeding the carrier strip successively through first and second loops, the second loop being reversed from the first loop, first and second movable transfer means operatively associated respectively with the first and second loops, each transfer means having a surface moving tangential to the labels as they move through a respective one of the loops, means securing each label to the surface of the associated transfer means as it moves through the convex side of the loop, the transfer means pulling each label from the convex side of the carrier strip as it moves through the associated loop.

2. Apparatus of claim 1 wherein the radius of the first loop is sufficiently large to prevent separation of the labels from the inner side of the carrier strip.

3. Apparatus of claim 1 wherein the first movable transfer means includes a cylindrical member, means for rotating said cylindrical member, said member having radial passages opening in the outer cylindrical surface, means applying a vacuum to the inside of the cylindrical member to draw air into said passages, the convex side of the loop being substantially in tangential contact with the cylindrical member, the outside surface of a label coming in contact with the cylindrical member as it passes through the adjacent loop and being held against the cylindrical member by the vacuum, rotation of the cylinder peeling the label from the carrier strip.

4. Apparatus of claim 3 wherein the radius of the first loop is sufficiently large to prevent separation of the labels from the inner side of the carrier strip.

5. Apparatus for transferring labels from both sides of a carrier strip to individual units, comprising:

a frame, first and second cylindrical members rotatably supported on the frame, means for rotating said cylindrical members, said members having radial passages opening in the outer cylindrical surface, means applying a vacuum to the inside of the cylindrical members to draw air into said passages, and means moving and guiding the carrier strip successively through first and second loops, one side of the carrier strip being on the inside of one loop and on the outside of the other loop, bight portions of the respective loops being substantially in tangential contact with the respective cylindrical members, the outside surface of a label coming in contact with a cylindrical member as it passes through an adjacent loop being held against the cylinder member by the vacuum, rotation of the cylinder peeling the label from the carrier strip.

6. Apparatus of claim 5 wherein said vacuum means applies a vacuum to the inside of the cylindrical members through a predetermined sector of the circumference, whereby air is drawn through holes around a sector of the outside surface of the cylindrical member.

7. Apparatus of claim 6 wherein the sectors remain stationary as the cylindrical members rotate.

8. Apparatus of claim 7 wherein the loops are positioned adjacent one end of the respective sectors.

9. Apparatus of claim 8 further comprising means moving the units to be labeled tangentially to the respective cylinder members adjacent the other end of said sectors, a label being moved into contact with a unit at the tangent point.
