1. The Jog mode activates the Jog Button and allows the operator to move the driven roll at the set speed only when the Jog Button is pressed The flexibility made possible by these two modes of operation allows greater precision when making laminations LAMINATING After selecting the speed pressure and direction of the laminator for your specific material lamination you need to control the material to be laminated in order to produce the best possible lamination The following is a list of aspects that will provide better control of your lamination e Always feed the material to the center of the rolls This allows the crown of the rolls to move air and wrinkles to the edges e Maintain back tension on the material to eliminate wrinkles e Use enough air pressure to provide a wrinkle free lamination e Keep the two materials to be laminated apart until they come together at the nip e Make sure the two materials are straight and aligned with each other before starting the laminator e Place the lead edge of your lamination on the center of the bottom roll then lower the top roll and start the drive for the best results 25 e Maintain the proper speed to control the lamination without wrinkles MAINTENANCE Maintaining the LL 100 A will provide many years of trouble free service The following is a list of actions that should be taken as needed e Onan annual basis it is advisable to lubricate the air piston shafts with lithium2.

WER UP Turn on the master power switch located on the back panel of the control cabinet directly above the power line receptacle It is also necessary to open the air supply line valve if you have the optional air cylinder model LL 100 A Photo 4 LL 100 A 23 PRESSURE REGULATION The desired laminating pressure must be determined and set prior to submitting material to the laminator The pressure on the nip can be adjusted by turning the adjusting thumbscrews located at each end of the pressure roll Turning the Thumbscrews clockwise will increase the pressure and counter clockwise will decrease the pressure Model LL 100 A optional air pistons Turning the Air Regulator knob located on the back of the control cabinet controls the pressure of the top roll at the nip Turning the knob clockwise will decrease the pressure and turning it counter clockwise will increase the air pressure The Air Gauge located on the control cabinet will display the current air pressure on the top pressure roll when it is in the down laminating position FLOW CONTROL VALVES The Flow Control Valves regulate the speed of the top pressure roll as it moves up and down Adjusting the valves in the following manner will regulate this movement It may also be necessary to adjust these valves to balance the movement of the air pistons in order for the top pressure roll to travel evenly If the speed of the two air pistons is not equal one side of the top pr
