There are several paper conversion processes. Some of the processes include reel slitting, perforating and packaging. Different types of paper converting depend on the use which the user has in mind.

Reel Slitting

Generally, paper is manufactured in large rolls and needs to be reduced into smaller rolls used for easier printing and other tasks. The process of cutting large rolls of paper into smaller rolls is called reel-slitting.

Perforating of Papers

Perforating paper involves puncturing the papers with a perforating machine, making small holes in the paper to make cutting easier. The perforations allow for the easy separation of a paper into different pieces following the line of the perforations.


The most commonly used material in the packaging industry is paper. Recycled paper, paper board and Kraft packaging are commonly converted to serve as packaging material.

L.A. Grinding offers paper conversion knives and blades for all types of paper converting processes including reel slitting, perforating and packaging. We carry stock blades for all major paper manufacturing and paper conversion equipment for the converting industry.
