The placement of Plate Speed Clamps for GTO 46 (single color)
Before you place the new speed clamps onto the machine, please check that the two register pins N16 & N18 are at their correct distance and correct side. If they are placed incorrectly, they will need to be changed to the correct position or sides by loosening the small screws (fig.9) that hold them. The difference between the two sides of pins is shown below in sketches A & B. If you use plates with no holes then you remove the two register pins. If in future you use plates with holes, you reinstall them very easily and simply.
Before you start the placement of the new speed clamps, clean the grooves of the cylinder well. Place a fine coat of grease on the bottom of each clamp and on the two sides (fig.1) where the trip blocks hold the clamp in the cylinder.
Start by placing the screws M6x75 (fig.6) along with their compression springs G53 into the threaded bushings and then add their nuts. Place the front clamp in its position. Screw the side trip blocks at their position. In order to place them easily, use a steel strip of 0,1mm thickness between the trip block and the clamp. Tighten well their screws and then remove the steel strip. Place the rear clamp in its position, screw and tighten the trip blocks, in the same way as you did in the front clamp. Screw the hexagon knuckled nut G16 provided that you have first placed the conical socket washer G15 on the right side (fig.10). Place and screw along with the security spring washer the socket button flange head screw (fig.7) on the top of the headless screw. Screw into its place the springs screw (fig.6) to the right depth and tighten its hexagon nuts. The upper and lower part of the clamps are connected together with a series of Hexagon socket countersunk head screws N02-M8X20 that are for adjusting, when required, the pressure that holds the plate. The adjustment is always regulated with the plate tightened. For the above adjustment, you must use a long hexagon socket key 5mm by moving it only a little. You have to use some strength because the above screws are secured with a plastic ring N50/N55.
There are compression springs N06 between the two parts of the clamp that help to open the upper part (of the clamp). The upper clamp opens and closes with the pin wrench with handle N46. In order to close the clamp, you have to move it forward to the lid end (fig.8). For the opening of the clamp, the pin wrench has to be moved backwards until you feel that it has fallen into a flat gap. The adjustment of the front clamp to turn it forwards or backwards, is done with the two knuckled thumb screws G43 & G44. One of these screws has a ring scale G45 on it and the adjusting block has an indicator pin G47. There are two hexagon socket set screws on the ring scale and one hexagon socket set screw on the indicator pin (fig.4) which with a hexagon screw key 2mm, regulate or adjust the position “O”. There are also two compression springs G46 on the knuckled thumb screws that hold the above screws fixed. Basically the operation of the new speed clamps is the same as the old ones. The difference is that these speed clamps hold the plate securely, permanently and are for a long life use.
