Throughout the text he uses this device along with other elements. The recoiler mandrel is fitted with separator discs which prevent interleaving of the narrower coil widths.In Pratt’s “The Shark”, the writer uses a lot of metaphor which are obvious. The recoiler, which takes up the slit coils on a driven, expandable mandrel.Without a tensioning device the slit material from the center of the master coil would take up more quickly while the outboard strips would hang loosely. A tensioning device is needed because the master coil is crowned or larger in diameter in the center of its width than at the edges. A tensioning device, which is placed between the slitter and the subsequent recoiler.These knives partially penetrate the coil stock causing a crack or fracture on both sides of the stock, separating the material. The slitter, which consists of two parallel arbors mounted with rotary cutting knives.The coil is fed into the slitter by either rotating or jogging the mandrel. The uncoiler, or pay-off reel, which tightly grips the master coil on its inside diameter using an expandable mandrel.Slitting is performed on slitting lines which consist of four basic devices: Rewind slitting involves rewinding the material through a number of knives to form narrower rolls of materials Slitting is considered a practical alternative to other methods due to its high productivity and the versatility of materials it can manage. Potential workpieces are selectively thin (0.001 to 0.215 in.) and can be machined in sheet or roll form. By today’s definition, slitting is a process in which a coil of material is cut down into a number of smaller coils of narrower measure. They would also use these saw mills to cut iron rods into smaller sections. The log slitting terminology refers back to the olden days of saw mills when they would cut logs into smaller sections.

Roll slitting, also known as log slitting or rewind slitting, is a shearing operation that cuts a large roll of material into narrower rolls. The machine used for roll slitting is called a slitter rewinder, a slitter or a slitting machine – these names are used interchangeably for the same machines.
