Tools required:
•1/4"
•Tape measure
To load film:
1.Retract the shaft locking plungers and remove the shafts.
2.Slide the shaft into the new roll of material until the end plate is tight to the end of the material. Always leave the end plate on the drive side locked down. This insures that the material alignment will be the same from roll to roll. See the material size chart to determine what end plate setting to use for differ- ent width materials.
3.Make sure the end plates are tight to the edge of the material. If the core protrudes out more than 1/8", it will be necessary to use a plastic spacer to fill the gap. (Provided in the accessory pack.)
4.Place the roll of material on the machine. Be sure to line up with the drive tang and slide the shaft over to engage it into the drive tang. Make sure the shafts are slid over and engaged. This is critical to prevent the material from shifting after the machine is webbed.
5.Repeat steps 1 through 4 for the unwinds and rewinds.
6.When all the material is loaded on the unwinds and all the empty cores are loaded on the rewinds, close the doors and lock in the shafts.
7.Open the doors and verify that the paper edge matches the edge of the vinyl by measuring from the side plate to the edge of the rolls. If the paper or vinyl do not match up, loosen the end plates and adjust the material so they are exactly in line.
8.Web the vinyl as shown in the diagram and secure it to the finished product rewind. For best results, align one edge of the rewind core to match the material edge measurement on the unwind.
9.Web the transfer paper and tape it to the front rewind as shown in the diagram. If the paper is wider than the vinyl, it will be necessary to use the slitters to cut the paper down to match the width of the vinyl. See “Setting the Slitter” on page
10.Load and web the overlaminate as indicated in the drawing. The operator has the option of lowering the pull roll now or waiting for the image to come through.
11.Check the web force for all the unwinds and rewinds and adjust as necessary.
12.Lower the main roll and start the motor. Start out at a low speed
13.Check for looseness at either edge of the paper just before it enters the nip. If a loose edge is detected, increase the brake
☞Note:
Initial looseness on the edge is common, It is caused by one of several things:
•No tension on the initial web before the roll comes down.
•Not webbed through perfectly straight.
•Web expansion from the heat as that stays in the nip area as the machine is webbed.
•The roll does not come down evenly.
14.Close the doors and increase the speed as required.
15.Observe the machine as it runs the material. Pay close attention to the web. Look for loose webs or spliced rolls and check the image quality.
IMPORTANT
When the process is complete, stop the machine and raise the roll. Do not let either paper or vinyl run through the nip alone. The vinyl could stick to the roll and the transfer paper would transfer to the bottom roll resulting in a large clean up job.
