Claims
- 1. A device for imparting rotational motion to a bottle moving on a conveyor comprising:
- A. a resilient surface arranged along one side of said conveyor;
- B. position-controlling means, arranged over said conveyor, for (1) controlling the position of said bottle as it moves on said conveyor against said resilient surface, said position-controlling means including a wheel lying in a horizontal plane and having a generally circular configuration with indentations on it slightly larger than the cross-sectional area of said bottles;
- C. a flexible belt, coupled to said position-controlling means and with a portion of said belt being in contact with said bottle on the side opposite to said resilient surface, said belt extending substantially across the openings of said indentations and having sufficient flexibility to allow the entrance of said bottle into said indentation; and motive means, coupled to said belt, for imparting to said portion of said belt a motion relative to said conveyor and to said wheel.
- 2. The device of claim 1 wherein said portion of said belt in contact with said bottle moves in the direction opposite to the direction of motion of said conveyor.
- 3. The device of claim 2 wherein said belt constitutes a closed loop in a taut condition and said motive means moves said entire loop.
- 4. The device of claim 3 wherein said belt, in the direction of the longitudinal axis of said bottle, has a small dimension relative to the dimension of said bottle along said axis.
- 5. The device of claim 4 wherein said motive means includes a plurality of rollers attached to said wheel and having a freedom of revolution about an axis perpendicular to the plane of said wheel with said belt held tightly against at least one of said rollers.
- 6. The device of claim 5 said device is totally unattached to said conveyor and is formed in a C-shaped configuration with the opening in said C-shaped configuration being sufficiently large for said conveyor to pass through.
