A REEL%u2022 Reel Width: The measurement of the face of the paper from side to side.%u2022 Outer Diameter: The width of the circle if the paper roll is placed on its side. The measurement is taken across (passing through the centre) of the roll.%u2022 Roll Length: The total number of metres of paper wound onto the roll.%u2022 Core ID (Inside Diameter): The size of the centre hole in the core. It is important because certain machines use a type of pin holder or spindle to support the roll and the core ID must match the size of these pins or spindles to function properly.%u2022 Core OD (Outer Diameter): The size of the entire core, including the hole.SHEETERSheeting is the process of cutting paper into specific lengths and widths. Sheeters can take large rolls and create smaller sheets of material for any requirement. Some machines can only do length and width cuts separately, while others can do both simultaneously.How to determine grain direction of a sheet when sheetingThe fibres run along the length of the reel. This happens during the paper-making process. If a reel%u2019s width is 610 mm and it is sheeted to a length of 860 mm, the resulting sheet will have a long grain. If the width of a reel is 860 mm and it is cut to 860 mm x 610 mm, it will be a shortgrain sheet.SLITTER REWINDERA machine that is used to cut (slit) rolls of material while they are being re-wound. The width could be slit to smaller sizes or the reels can be rewound to smaller OD reelsHow a slitter rewinder worksA slitter rewinder has three main components: the unwind, the slitting mechanism, and the rewind. The machine starts when a master roll of material at a given width is loaded into the unwind. As the material is being fed out of the unwind, the slitter component then begins to cut the material into smaller widths following whichever setting you initially programmed the machine to. After slitting the material, the strips then get rewound onto a different core that%u2019s the same width.SIMPLE WAYS TO DETERMINE THE GRAIN DIRECTION%u2022 Bend: Gently bend the paper in both directions to determine which yields more easily. The paper fibers run in the direction that gives the least resistance.%u2022 Fold: Fold and crease the paper first in one direction and then the other. If the paper f ibers crack and break, you are folding against the grain. %u2022 Wet: Lightly spray the paper with water, and it will curl in the direction of the grain.%u2022 Tear: Take a sheet of paper and tear it horizontally, then vertically. The straighter tear is parallel to the grain; the more jagged tear is across the grain. LongGrainShort Grain40%u201d40%u201d 28%u201d28%u201dRollDiameterWidthInside CoreDiameterOutside CoreDiameter12
