Abstract: A device for wrapping sheet, such as a foam panel, about a tubularly shaped object article, such as pipe sections of a pipeline. The device engages the substantially flat sheet and cams it about the curved pipe body circumference by pivoting yokes so as to cause the sheet to be wrapped about the pipe body. After the sheet is wrapped about the pipe body its free edges are fastened together so that the device can be removed.
