Abstract: A welding carriage has a frame that is adjustable in width and height and is guided by the sides of a workpiece. First and second wheel assemblies support the frame upon the workpiece, the first and second wheel assemblies forcibly engaging the sides of the workpiece for guiding the frame along a path substantially parallel thereto. The frame comprises two opposing lateral sides interconnected by a linkage therebetween. The linkage can be actuated to adjust a coarse width of the frame, dimensional variations being handles by biased guide wheels of the second wheel assembly. Each of the opposing lateral sides further has vertically adjustable leg posts for adjusting a vertical height of the frame.

Abstract: A shade for an arched window including an arched track with a movable carriage and a shade member attached to the carriage. A cord actuates the carriage to move along the track and pull the shade member between collapsed and extended positions. A central hub permits the shade member to move laterally as the shade member is moved between the collapsed and extended positions.

Abstract: A machine and method for wrapping cylindrical workpieces such as rolls of bathroom tissue and paper towel. The machine includes a workpiece infeed conveyor, a wrapping paper feeder, a rotating carousel having a plurality of pockets, and a discharge conveyor. A piece of wrapping paper supplied by the paper feeder is perforated and burst into a single sheet. The sheet and a workpiece are directed into a pocket in the rotating carousel whereby the sheet is banded around the periphery of the workpiece by a clamping plate, underfolder plate, and brush. Next a pair of stuffer spindles driven by a barrel cam and a pair of rotating star wheels whose compound motion is derived from geneva wheels fold and tuck the wrapping paper around the parallel sides and into the center tube of each workpiece. The wrapped workpieces are ejected from the rotating carousel onto a discharge conveyor. Alternative folder mechanisms include folding fingers. The method of wrapping is also disclosed.
