Abstract
An apparatus for flame treating an exterior surface of a plastic container such as a barrel includes a carriage mounted on a frame for rotatably supporting a plastic container, a first treatment station attached to the frame for flame treating a facing end of the container and a second treatment station attached to the frame for flame treating the sides of the container. The carriage is attached to a cable driven by a first actuator for moving the carriage from a starting position for loading the container onto the carriage past the first station to the second station and back to the starting position. The carriage, a burner at the second station and a roller for rotating the container at the second station are all adjustable for accommodating various diameter containers.
Claims20
An apparatus for flame treating an exterior surface of a plastic container comprising:
- a frame;
- a carriage for rotatably supporting a plastic container, said carriage mounted for movement on said frame and having means for engaging an exterior surface of and rotatably supporting the plastic container;
- a first treatment station to said frame for flame treating an end of the container;
- a second treatment station attached to said frame and spaced from said first treatment station for flame treating sides of the container;
- means mounted on said frame for moving said carriage from a starting position past said first treatment station to said second treatment station and moving said carriage from said second treatment station past said first treatment station to said starting position;
- and
- means attached to said frame adjacent said second treatment station for ejecting the container from said carriage.
An apparatus for flame treating an exterior surface of a plastic barrel comprising:
- a ground engaging generally horizontally extending frame;
- a carriage movably mounted on said frame and including means for engaging an exterior surface and for rotatably supporting a plastic barrel;
- a first treatment station attached to said frame for flame treating a facing end of the barrel;
- a second treatment station attached to said frame and spaced from said first treatment station for flame treating sides of the barrel;
- and
- means mounted on said frame for moving said carriage from a starting position past said first treatment station to said second treatment station and from said second treatment station past said first treatment station to said starting position.
An apparatus for flame treating an exterior surface of a plastic barrel comprising:
- a ground engaging frame;
- a carriage movably mounted on said frame and having means for engaging an exterior surface of and for rotatably supporting a plastic barrel with the axis of rotation of the barrel in a horizontal plane;
- a first treatment station attached to said frame for flame treating a facing end of the barrel;
- a second treatment station attached to said frame and spaced from said first treatment station for flame treating sides of the barrel;
- means mounted on said frame for moving said carriage from a starting position past said first treatment station to said second treatment station and back to said starting position past said first treatment station;
- and
- means attached to said frame adjacent said second treatment station for ejecting the barrel from said carriage.
