Roll slitting is a shearing operation that cuts a large roll of material into narrower rolls. There are two types of slitting: log slitting and rewind slitting.
In log slitting the roll of material is treated as a whole and one or more slices are taken from it without an unrolling/re-reeling process.
In rewind slitting the web is unwound and run through the machine, passing through knives or lasers, before being rewound on one or more shafts to form narrower rolls.For rewind slitting the machine used is called a slitter rewinder, a slitter or a slitting machine
LOTOS slitter machine is designed to easily integrate with new or existing equipment. All of these units feature mounting holes for added convenience and various options for ease of use. Equipped with precision top and bottom shafts and a state-of-the-art locking system, blades can be quickly and easily adjusted or changed and secured back in place to accommodate different width cuts. Roll slitting machine for sales is applicable to coils of various specifications. It is used for slitting the coil into required width for the use of punch line through the procedure of uncoiling, pre-leveling, cropping, slitting and recoiling. It has advantages such as proper layout, easy operation, highly automated and high production efficiency.
