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 (the 'log') and one or more slices are taken from it without an unrolling/re-reeling process.
The cutting stock problem was first formulated by Kantorovich in 1939. [4] In 1951 before computers became widely available, L. V. Kantorovich and V. A. Zalgaller suggested [5] solving the problem of the economical use of material at the cutting stage with the help of linear programming. The proposed technique was later called the column ...
Shearing, also known as die cutting, [1] is a process that cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations. [2]
Both industrial roll-to-roll and sheet-to-sheet systems typically feature slot-dies in the range of 300 to 1000 mm in coating width, though slot-dies up to 4000 mm wide have been reported. Commercial slot-die systems are claimed to operate at speeds up to several hundred square meters per minute, [ 14 ] with roll-to-roll systems typically ...

Inorganic LED - Flexible LED is commonly made into 25, 50, 100 m, or even longer strips using a roll-to-roll process. A long neon LED tube is using such a long flexible strip and encapsulated with PVC or silicone diffusing encapsulation. Organic LED (OLED) - OLED for foldable phone screen is adopting roll-to-roll processing technology.

Rotary die cutting is die cutting using a cylindrical die on a rotary press and may be known as a rotary die cutter or RDC. A long sheet or web of material will be fed through the press into an area known as a "station" which holds a rotary tool that will cut out shapes, make perforations or creases, or even cut the sheet or web into smaller parts.
