The placement of Speed Clamps for Roland Rekord iiiB Gray

In order to remove the old clamps easily do the following: Screw the 4 operating screws of the front clamp creating space so as to unscrew the front screws of the 3 retainer parts (fig.3A). Unscrew the operating screws of both clamps completely to reduce the spring’s pressure. Remove the back screws (fig.3B) of the 3 retainer parts of the front clamp. Unscrew and remove the two springs’ retainer parts along with the springs and their shafts. The front clamp is now released and taken off. Since you have removed the front clamp, pull and remove also the rear clamp. After having removed the clamp, you can remove the three retainer parts of the clamp more easily.

Clean the whole cylinder cavity well and scrape any dry ink, old dyes and rust. The two springs’ retainer parts will be placed in new positions as well as the middle retainer part R33 of the rear clamp. Remove the grub screws from the new positions SKETCH A and place them in the old positions using necessarily threadlocker. Check the front clamp if the two register pins N17 & N19 are at their correct sides depending on what kind of punch machine for the plate you use because there is a difference of 1mm in the depth of cutting the plate between the various punch machines. If the register pins need to be changed, you have to loosen the screws (fig.9) that hold them. You remove them and you reinstall them on their opposite sides. The difference between the two sides of pins is shown in sketches B and C. 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. Firstly, spread a fine film of grease on the two surfaces of the 3 retainer parts of the rear clamp that come into contact with the clamp and on the external points of the rear side of the cylinder cavity. Do the same with the 3 retainer parts of the front clamp and on the external points of the front side of the cylinder cavity. Place the 3 retainer parts of the rear clamp in their positions SKETCH A, without the clamp, and tighten their screws well. Place the rear clamp in its position along with its two springs R02 and the springs’ shafts (the springs cannot be compressed before their placement). Place the two retainer parts of the springs in their new positions by compressing the springs and screwing their screws well. Place the front clamp in its position in the cylinder cavity along with its three retainer parts R24/R23/R24 and with the two springs R02 compressed and secured with pins (fig.11). If the springs are not in their place, put them in place, compress them and secure their shafts R03 with pins (fig.11). By the operating screws, press the springs more, in order to create the required space for the front screws (fig.3A) of the retainer parts. At first, take off the two pins (fig.11) that keep the springs compressed. Put the screws without tightening well. Unscrew the four operating screws completely in order to shift the clamp forward. Put and tighten well the rear screws (fig.3B) of the three retainer parts. Return again by the operating screws of the clamp to the front screws (fig.3A) of the three retainer parts and tighten them well. The new speed clamps are now in place.

THE OPERATION OF SPEED CLAMPS

The upper clamp opens and closes with the lever wrench N43. 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 lever wrench has to be moved backwards until you feel that it has fallen into a flat gap. The upper and lower parts of the clamps are connected together with a series of Hexagon socket countersunk head screws N01-M10X35 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 6mm by moving it only a little. You have to use some strength because the above screws are secured with a plastic ring N52/N57. There are compression springs N09 between the two parts of the clamp that help to open the upper part (lid).

-In order to place the new plate you have to do the following:

FRONT CLAMP: The end adjusting screws R19 must not push the clamp right or left so that the self-centering mechanism R12/R10/R11 can keep the clamp automatically in the center. If during the set-up you use the end adjusting screws to move the clamp right or left, keep these screws tightened till the end of the particular work. By the two operating side screws R25 place the clamp in position “O”. In this position, the horizontal line (fig.4) of the ring scale N30 is aligned with the face of the clamp and the bold vertical line is on the top. If later the indicator needs correction, there are two small screws (fig.7) that will put it in the right place. For the above adjustment, you can also use the two indicator sets N37 so as the middle thick line (fig.6) to be aligned with the face of the clamp.

REAR CLAMP: At first, use the special toothed screw (red) N63, which you turn left, to move the clamp toward the side of the cylinder. Place the 4 operating rear clamp screws R35 in position “O”. In this position, the horizontal middle line (fig.5) of the screw’s ring is aligned with the face of the clamp. Bring the two pieces of the rear clamp in the center by using either the end screws R19 or by pushing the clamp. Align the two parts of the split rear clamp with the groove (fig.10) of the middle retainer part R33 and correct the margin between them by using the double adjusting screw R18. Place the new plate as always. Remember to press the lever wrench N43 so that the clamp is closed and the lever wrench touches the upper part of the clamp (fig.8). It is better not to close the first part of the clamp to the end. It is preferable to close the second immediately and then go back to the first for the final closure. In this way the plate does not warp. After that, turn the special toothed screw (red) N63 of the mechanism, to the right, for fast shifting of the rear clamp.

ATTENTION: This special screw (red) N63 must be turned up to the end, until you feel that it has reached the end of its cycle.

SPECIAL ATTENTION MUST BE TAKEN IF IT IS DIFFICULT TO BE TURNED. IT IS NECESSARY TO UNSCREW LIGHTLY THE 4 OPERATING SCREWS R35 OF THE CLAMP FOR THE STRETCHING OF THE PLATE. THIS SPECIAL SCREW IS NOT FOR COMPLETELY STRETCHING THE PLATE. IT IS JUST FOR MOVING THE CLAMP IMMEDIATELY, WITHOUT USING MUCH FORCE. The function of the special screw (red) N63 has been completed. As mentioned above do not use this special screw for the final stretching of the plate or for the different adjustments on the clamps. Tighten the 4 operating rear clamp’s screws R35 completely and do the same at the front clamp’s operating screws R25/R26. From now on, the operation of the clamps for the final coincidence of the colors or for the corrections, is, as it was with the old clamps.
