1. is to close The height of the envelopes must not exceed 20 m m By streamfeed printing machines the suction head is adjusted by normal standards REMEMBER always to tighten the lay at the side mounts and install the quick suspenders so that the feeder stands solid Part A 6 The stack height is adjusted by turning the adjusting screw next to the switch On the JOG lay Smaller stack turn clockwise and bigger stack turn counter clockwise It is advisable not to run too many envelopes at a time about 12 The sensory arm of the stack switch can be pushed both sideways and backwards forward by loosening the small screw at the end of the shaft In case of envelopes with open flap the sensory arm is moved so that it rests on the envelope not the flap In case of small format envelopes it s advisable to pull the sensory arm back so it rests about 5 m m from the back edge Spot Suction Connect the spot suction the vacuum pump starts and a spot suction is established at the trailing edge of feeder board This will increase the friction at the back edge of the envelope It gives the opportunity of a closer and more precise overlap of the envelopes but sometimes the feeder runs better when not using the spot suction For example concerning thin envelopes which can not stand too hard a suction the suction at the front feeders under frame can be turned down When using spot suction too large a friction can arise with the result that2. LGS Envelopefeedersystem User guide To LGS 5000 6000 7000 Part A 2 Thank you for choosing the LGS Feeder LGS feeder is useful for many different tasks in your printing house Before you put your envelope feeder into use we recommend you to read this book of instructions carefully Envelopes To obtain a run without problems it will be of great use and advantage that you choose the envelopes best suited for the LGS envelope feeder Some products will cause problems but alternative supplies will almost be available Also consider carefully the way you keep the envelopes The supplier of envelopes will always be able to advise you When buying envelopes please notice that envelopes in stock for a longer period do not run as smoothly as new envelopes This is not a problem particularly concerning the LGS envelope feeder system other products of envelope feeders have similar problems It s also important that the envelopes are accurately limed Instructions It s necessary the feeder stands on a plane floor otherwise the conveyor table will be awry proportional to the suctions in the offset machine When moving the feeder in the printing house make sure you do not push to hard or run into broken surfaces which will cause the feeder to overturn The feeder must ONLY be connected to the voltage listed on your LGS envelope feeder Turn the main switch of the feeder to position ON and the current is connected
3. Part A 3 Auto Manual switch Turn the switch to AUTO and the machine starts to run The suction motor of the conveyor table and feeder board starts up and the switch on the frontal conveyor table takes over the propelling motor Manual drive Forward Manual is selected by turning the switch to MAN Push the switch FORWARD and the conveyor belt is set in motion The switch is used for adjustment of conveyor table lateral steering gear and wheels etc Manual drive Reverse Operate the switch REVERSE the conveyor belt moves reverse this is useful if something get jammed Up Down When operating the UP or DOWN button the feeder either is raised or lowered to the level required for operation Stop When activating the switch STOP all functions of the feeder is disconnected however this is not a power switch so when the machine is not in use set the main powers switch to OFF Adjustment of the feeder board Place the envelopes on the feeder board Loosen the locking handles placed on the side of the dosing plate push the plate towards the envelopes and lock the handles in required position Envelopes with folded flaps are placed with the flaps facing the dosing plate and the back edge of the envelopes parallel with the trailing edge of the suction box Envelopes with open flaps are placed with the flaps overhanging the trailing edge of the suction box so the suction does not catch the flaps The best way of running large env
4. elopes is to place them crosswise of the feeder board this does only apply LGS 6000 7000 Push the lateral steering gear towards the envelopes leaving about 1 m m space The dosing plate is equipped with interchangeable dosing angels These angels are numbered from to 6 Part A 4 The difference is the angel and it depend on the envelopes which to use As already described there is a great difference in envelopes and therefore you need these different dosing angels to get the most smoothly run When changing the dosing angle Loosen the two bolts pull the dosing angle press the new dosing angle home and tighten the bolts again Running the feeder board Turn the switch to MAN and press the switch FORWARD Place the envelopes under the dosing plate and turn the handle for adjustment the handle is placed at the top of the plate The handle for adjustment must be turned very slowly while it is rather quick in reaction 1 8 revolutions can be too much Turning the handle clockwise the distance gets smaller the layer of envelopes becomes thinner and the distance between the envelopes is widening Turning the handle counter clockwise the distance gets bigger and more envelopes will be running through and the distance between them will be shorter By switching off the current for the machine the bands which hold the envelopes in the rotation system can be moved The bands at the upper band controller can then be moved from one point to t
5. he next Turn the machine on switch to MAN and operate the REVERSE switch for a moment the bands will then be straightened out When the dosing plate is adjusted the envelopes are pressed down to the conveyor table so that the rollers are in contact with the first envelopes now you can start the adjustment of the conveyor table IMPORTTANT Please notice that the envelopes run under the shaft which holds the rollers Part A 5 Conveyor table Adjust the lateral steering gear by loosening the locking screws at the holders Push the lateral rails of the lateral steering gears towards the envelopes to a distance of about 5 m m on both sides Assemble the stop of the front plate Place an envelope towards the front plate Push the lateral steering gears towards the envelope to a distance of about 1 m m If the holders of the lateral steering gears are too short the can be increased by enclosed extension bars IMPORTANT The plastic front guide is only for envelopes with glued front edge JOG system Adjust the JOG system by moving the jog lay towards the back of the edge of the envelopes Switch the JOG switch to position MAN Operate the JOG switch momentarily so that JOG lay moves to the most extended position Adjust the JOG trailers parallel by turning the adjustment ring in the trailer arm The spring extension is adjusted at the two holes in the cover 4 m m Hex The envelopes must not move while jogging If they do the lay
6. l as well and if it is tilted the feeder must be tilted proportionally Loosening the locking handle by the hand wheel of the feeder does this When the feeder is tilted lock the handle again Turn the switch to MAN Press the UP or DOWN button to get the right height Turn the printing machine until the suction shaft is in bottom position Turn the board up towards the supporting roller and lift the feeder towards the suction shaft about 2 3 m m from the top envelope of the stack Push the lateral steering gears of the printing machine towards the transport table of the feeder and lock them if necessary This is important in order to avoid the feeder moving sideways IMPORTANT Always take care that the suction and the sheet separator is sound that the adjustment of the printing machine is correct and the suction works well Some printing machines are fitted with a transverse paper feeler This is not for use lift up so it has no contact with the feeder and the envelopes Remember to release the table transport Adjust the suction and blast air Do not use too much blast air as it affects the stacking contact Part B 1 IMPORTANT When installing of cable sockets be sure that it s done correctly and that the underground cable always is connected The machine is fitted with a vacuum pump This is protected of a relay which will declutch when overloaded clogged up filters air escape blast out of order temperature too high it m
