Wrapping machine

Abstract

A device for wrapping a sheet material about an object is disclosed such as a heat shrinkable plastic material about a container in a shrink bundling process. The device is able to cover both the top and the bottom of the container or in the alternative cover only the top of the container with the use of auxiliary glue guns. The device comprises a frame having a conveyor for moving the container. A first sealing member includes a plurality of sealing elements rotatably mounted on a hub which is journaled to the frame. A second sealing member is slidably mounted to the frame for cooperation with one of the plurality of sealing elements. The sheet material extends between the first and second sealing members whereat the second sealing member engages a first of the plurality of sealing elements to sever the sheet material at the leading edge of the object. Rotation of the first sealing member positions a second of the plurality of sealing elements adjacent the second sealing member. The second sealing member and the second of the plurality of sealing elements sever the plastic material at the trailing edge of the object. The invention also resides within the method of wrapping an object with sheet material. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
