Select from the general listing below:
jaw fold(er)
Also called a tucker fold. One or two folds are created in a web, at right angles to the direction of web travel, by the use of a two or three cylinder device. The lead edge of the web is caught by some means on the first cylinder (commonly by pins which penetrate the paper; the effect can be observed on a newspaper fold) which carries it around the first cylinder. Half way around, a tucker blade on this cylinder forces the center of the soon to be folded web, into the folding jaw on the second cylinder. The jaw closes, thus creating the fold. At the same time or subsequently, a cut-off knife separates the tail of the signature from the web. The signature is carried around the second cylinder and released by the jaw and the cycle continues. The signature can be passed to a third cylinder in a similar manner to make a second parallel jaw fold.
