Abstract

A tape transport system for printed products includes a tape having a tape width, a pulley, and a lever arm supporting the pulley, the lever arm having a first side and a second side. The pulley has a first section disposed on the first side of the lever arm and a second section disposed on the second side of the lever arm, the first and second sections supporting the tape so that the lever arm is within the tape width.

Claims

1. A tape transport system for printed products comprising:

a tape having a tape width,

a pulley, and

a lever arm supporting the pulley, the lever arm having a first side and a second side,

the pulley having a first section disposed on the first side of the lever arm and a second section disposed on the second side of the lever arm, the first and second sections supporting the tape so that the lever arm is within the tape width.

2. The tape transport system as recited in claim 1 further comprising a second tape, a second pulley, and a second lever arm supporting the second pulley, the second pulley having a second pulley first section on one side of the second lever arm and a second pulley second section on another side of the second lever arm.

3. The tape transport system as recited in claim 1 wherein the pulley includes a bearing with a rotatable inner race.

4. The tape transport system as recited in claim 1 further comprising a second pulley on the lever arm, the second pulley having a second pulley first section on the first side and a second pulley second section on the second side.

5. The tape transport system as recited in claim 4 wherein the tape contacts the pulley and the second pulley in a 180 degree fashion.

9. The folder as recited in claim 1 wherein the first pulley includes a bearing with a rotatable inner race.

6. A method for transporting printed products comprising:

rotating a tape for transporting the printed products, and

passing the tape over a pulley on a lever arm, the lever arm having a first side and a second side, the pulley having a first section disposed on the first side of the lever arm and a second section disposed on the second side of the lever arm, the first and second sections supporting the tape so that the lever arm is within the tape width.

7. A folder comprising:

a tape transport system for printed products including a first tape having a first tape width, a first pulley, and a first lever arm supporting the first pulley, the first lever arm having a first lever arm first side and a first lever arm second side, the first pulley having a first pulley first section disposed on the first lever arm first side and a first pulley second section disposed on the first lever arm second side, the first pulley first section and first pulley second section supporting the first tape so that the first lever arm is within the first tape width; and

including a second tape having a second tape width, a second pulley, and a second lever arm supporting the second pulley, the second lever arm having a second lever arm first side and a second lever arm second side, the second pulley having a second pulley first section disposed on the second lever arm first side and a second pulley second section disposed on the second lever arm second side, the second pulley first section and second pulley second section supporting the second tape so that the second lever arm is within the second tape width; and

a printed product transfer device including at least one component passable between the first tape and the second tape.

8. The folder as recited in claim 7 wherein the component is a gripper.
