Concrete leveling apparatus

A folding scaffold unit having first and second pairs of poles each positioned perpendicular to the floor and parallel with each other, each pair of parallel poles being connected by connecting rods, scaffold boards being fixed to horizontal shafts at one ends thereof, the horizontal shaft being inserted into each pair of parallel poles and parallel with the connecting rods, the other horizontal shafts parallel with the horizontal shafts and rotatably connecting the other ends of the scaffold boards, a driving gear mounted on one of the pair of parallel poles for vertically swingably moving the scaffold boards, and gears fixed to the other horizontal shafts and having tooth flank meshing with each other.

A cleaning machine for a printer is provided for cleaning an outer peripheral surface of a cylinder of the printer with a cleaning cloth through a pressure pad mounted through a holder on a mount member supported by side plates of the frame of the printer. The cleaning cloth is moved relative to the outer peripheral surface of the cylinder of the printer. The pressure pad is composed of a projected member made of elastic material. The projected member includes a flange portion, a first projected portion toward the cylinder and a second projected portion projected toward the mount member. The first and second projected portion is symmetric with each other for reversible use, resulting in prolonging the service life of the pressure pad.

Cleaning machine for a printer

A printing cylinder cleaning apparatus for cleaning, for example, a blanket surface on a blanket cylinder of an offset press has a continuous cylinder cleaning cloth stretched between a cleaning cloth supply roll and a cleaning cloth take-up roll which are rotatably mounted on side plates of the frame of a printing machine, whereby the cylinder cleaning cloth being capable of running relative to the outer peripheral surface of a cylinder of the printing machine in contact therewith. The cylinder cleaning cloth is pressed by a suitable pressing member onto the outer peripheral surface of the cylinder of the printing machine. The apparatus further has a cutter which is disposed to cross a common line which is tangent to outer peripheral surfaces of the cleaning cloth supply roll and the cylinder respectively. In case of breakage or tearing of the cloth, the portion caught and stretched by the cylinder is cut by the cutter.
