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 .

Tricot machines are produced with 2, 3, or 4 guide bars. Tricot machines have a vast application, such as elastic and non-elastic mesh fabric, velvet fabric, and others. Tricot machine generally uses E28, E32, E36, and E40. At present, the widest working width of tricot machine has reached 335 inches. [6]
The term squaw is considered offensive by Indigenous peoples in America and Canada due to its use for hundreds of years in a derogatory context [3] that demeans Native American women. This has ranged from condescending images (e.g., picture postcards depicting "Indian squaw and papoose ") to racialized epithets.

In the simplest turntable systems, stretch is achieved by rotating the load at a speed in which the take-up demand on the load surface is faster than the rate at which the film is allowed to be fed, being limited by a brake system.
A typical industrial roll-to-roll process line. In the field of electronic devices, roll-to-roll processing, also known as web processing, [1] reel-to-reel processing or R2R, [2] is the process of creating electronic devices on a roll of flexible plastic, metal foil, or flexible glass. [3]
The typical machine is loaded with a continuous flat roll of plastic film, which has usually had labeling and artwork applied. Plastic is the most commonly used packaging material in the food industry, but the technology can be used to form continuous metallized foil/film, paper, and fabric product containers by changing the edge sealing/seaming methods.
