When feeding sheets ranging from 5mm flimsy vinyl, to chip board, wrapped plastic, leather or vinyl, the following points will be helpful:
1. In feeding 5mm vinyl, the main consideration is to support the material until it is delivered to the bottom gauge band.
2. Roll or bend the material in a manner that causes the bottom portion of the sheets to act as a support.
3. The proper angle for the magazine back support is very important. If the angle is too far forward, the vinyl will fall forward. if the angle is too far backwards, the stock will slide over the bottom rail and into the machine.
4. To level the feeding edge, the best technique is to level the pile with shims. Materials such as 80lb cover stock can provide the proper support or shim.
5. The side combers and the bottom combers are always a consideration for proper feeding. if there is too little tension, double sheet feeding can occur, or the sheets will feed skewed. Too much tension and the sheet will not feed.
6. For heavy board, proper sucker selection is a key factor. Tan or black rubber suckers work quite well.
7. For proper feeding of heavy board stock, the correct stock sensor arm adjustment is necessary; also, feeding smaller lifts of heavy board is recommended, as shimming is easier with smaller lifts.
8. Utilize the magazine aprons to help support the heavy stock during its travel to the bottom gauge band.
