Papermaking

Papermaking is the process of making paper, a substance which is used ubiquitously today for writing and packaging.In papermaking a dilute suspension of fibers in water is drained through a screen, so that a mat of randomly interwoven fibers is laid down. Water is removed from this mat of fibers by...

Molding (process)

Molding or moulding is the process of manufacturing by shaping pliable raw material using a rigid frame or model called a pattern....

 to gather up woodpulp from a vat for pressing and drying into sheets. It helps to control the size of the paper produced. Paper with a feathered or soft edge is often said to have a "deckled" edge for this reason (as opposed to a cut edge).

Paper can have two types of deckled edge: natural deckles or tear deckles. Natural deckles are the result of the deckle used in mould-made paper, whereas tear deckles are the result of tearing the paper.

Paper can have two types of deckled edge: natural deckles or tear deckles. Natural deckles are the result of the deckle used in mould-made paper, whereas tear deckles are the result of tearing the paper. Often mould-made paper will have a combination of deckled and cut edges depending on the specific size of paper required.

In film processing, deckles are die inserts that set the coating width of a slot die coater or the extrusion width of an extrusion die. They work by constraining the flow as the material exits the die. Since some materials have a tendency to neck in or spread out after leaving the die, deckle position may need to be compensated to achieve the target width.
