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.
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]
Roll-to-roll processing has been used in the manufacture of electrochemical devices such as batteries, [6] supercapacitors, [7] fuel cells, [8] [9] and water electrolyzers. [10] Here, the roll-to-roll processing is utilized for electrode manufacturing and is the key to reducing manufacturing cost [11] through stable production of electrodes on ...
This method solves the cutting-stock problem by starting with just a few patterns. It generates additional patterns when they are needed. For the one-dimensional case, the new patterns are introduced by solving an auxiliary optimization problem called the knapsack problem , using dual variable information from the linear program .
The Zeisel determination or Zeisel test is a chemical test for the presence of esters or ethers in a chemical substance. [1] [2] [3] [4]It is named after the Czech chemist Simon Zeisel (1854–1933).
The coil is then slit to the desired width through the process of roll slitting. Stainless steel strip [5] is the extension product of strip steel, usually long and narrow stainless steel strips are manufactured to meet the demands of various industrial and mechanical areas. According to the processing method, the stainless steel strip can be ...

Rolling schematic view Rolling visualization. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property.
