LOADING A ROLL OF MATERIAL
•Turn the unwind brake fully towards you so there is no brake tension on the unwind shaft (until no gap is visible between the unwind brake and the lock collar).
•Swing out the desired unwind shaft towards you and slide a roll of material onto the unwind shaft. Ensure that the rubber blocking cords are on the top and bot- tom of the shaft for easy loading (see below).
Figure 10. Loading Roll of Material
•For the bottom unwind shafts rotate the outer section of the locking receiver towards you to open the receiver so the shaft can be pulled out and loaded with material (see Figure 11).
IMPORTANT! Make certain that you place the roll of film on the unwind shaft so that the material will feed with the adhesive side facing away from the rollers.
IMPORTANT! Swing the unwind shaft in towards the receiver making sure to align the cutout notch in the end of the unwind shaft with the receiver notch. Press the unwind shafts firmly into the receivers to prevent tension and tracking problems.
Figure 11. Locking Receiver
•Remember to lock the receiver on the bottom unwind shaft so the film tracks correctly and the unwind shaft does not pull out of the receiver.
•Center the films on the unwind shafts using the rulers on the unwind shafts for alignment.
IMPORTANT! The position of all films, boards, rolls of media and cardboard cores for
•For alignment accuracy, pull a length of film forward off the top unwind shaft until it drapes over the film on the bottom unwind shaft. Make sure the edges of both film rolls line up.
•Now secure the rolls of material onto the shafts by grip- ping the shafts with one hand while rotating the rolls of material with the other hand in the direction it will be pulled off the unwind shafts. The rubber blocking cords will catch on the inside of the material core and hold the material secure on the shaft.
•If material needs to be rotated, turn the shafts, not the rolls of film otherwise the roll of film will no longer be secure to the shaft.
Unwind shaft cord adjustment
NOTE: If the end of the shaft is not correctly aligned you will not be able to adjust the brake tension proper- ly, causing tracking problems and possibly damaging the end of the shaft.
NOTE: Over time the rubber blocking cords will stretch and need to be shortened slightly. To adjust the cord, unfasten the cord at one end and cut off .39" (1cm).
