Abstract

A forming and wrapping unit and method for forming material into a continuous bar and wrapping the material. The unit including a forming chamber for forming material into a continuous bar, a sheet wrapping device for wrapping the continuous bar, and a controller operating on the sheet wrapping device. The sheet wrapping device and the controller are adapted to be operable independently of a rate of feeding bulk material into the forming chamber. The method includes feeding material to a wrapping position while forming the material, wrapping a sheet around the material such that the sheet at least partly overlaps a previously wrapped portion of the sheet, and transferring the wrapped material from the wrapping position to a storage ready position. The feeding of the material to a wrapping position and wrapping a sheet around the material are separately operable.
