Lithographic presses, JL-series. Polymetaal. Assembly instructies.
This drawing shows the main parts of the lithographic presses JL-series, in "exploded view".
Normally the client receives the press in assembled state.
The only parts that might have been taken off, for transport reasons are :
1. The pressure system (1.) that should be mounted on top of the press. Just let this part slide between the two side frames (the lever bar on the same side as the drive system, parts 5 through 9) and bolt it together again.
2. Also for transport reasons, the crank and the metal cover of the gearing might be taken off. If that is the case;
a. If the main toothed wheel (6.) is not in place, insert the short key (3.) into the slot of the roller (2.) which is already in position between the side frames.
b. Slide ther main toothed wheel over the shaft of the roller ans secure the wheel by mounting the ring (8.) with a bolt.
c. Mount the auxilary shaft (5.) onto the side frame with four screws (tighten them with Allan-keys).
d. Bring the steel gearing cover in place. Secure it with three small hexagon bolts.
e. Put some grease onto the auxilary shaft (5.) and slide the crank over the shaft. Secure the crank with a ring and screw.
Description of the assembly of a litho press.
The bed of the litho press has not been shown on the exploded view for clarity reasons. Now the bed must be brought into the press between the two side frames. The side of the bed with the grip must be on the side of the buffer in tube number (15.) Adjust the hight of the bars (10.) which is possible since they are mounted in slotted holes in the side frames. There should always be some play between the white plastic rollers on these bars and the bed. This play is needed in order to be sure that the bed has always a good contact with de main roller. If this contact is not optimal, it might result in slippage.
