Abstract
The present invention provides a method and apparatus for pleating paper. The apparatus includes a pair of pleating rollers, means to rotate one of said pleating rollers, a first pair of support rollers in supporting contact with a first of said pair of pleating rollers and a second pair of support rollers in supporting contact with a second of said pair of pleating rollers. Each of said pleating rollers has a plurality of radially reduced sections. An elongated pleating finger member is positioned in at least a plurality of radially reduced sections, and means are provided to movably support each of said elongated pleating finger members.
Claims24
An apparatus for pleating paper comprising, a pair of pleating rollers, means to rotate one of said pleating rollers, each of said pleating rollers having a core shaft;
- at least one support roller in peripheral supporting contact with a first of said pair of pleating rollers and at least one support roller in peripheral supporting contact with a second of said pair of pleating rollers, each of said pleating rollers having a plurality of radially reduced sections, a plurality of pairs of elongated pleating finger members, a pair of elongated pleating finger member positioned in each of at least a plurality of radially reduced sections, and means to movably support each of said elongated pleating finger members.
The method of pleating papers comprising;
- a—feeding paper between a pair of pleating rollers,
- b—peripherally supporting a first of said pair of pleating rollers with at least a first support roller,
- c—peripherally supporting a second of said pair of pleating rollers with at least a second support roller, each of said pleating rollers having a plurality of sets of keys, said keys being radially reduced sections, a pair of elongated pleating finger members positioned in each of at least a plurality of said sets of keys,
- d—adjusting the distance between pairs of elongated pleating fingers by a predetermined amount and thereby producing pleats of a predetermined height, and
- e—adjusting the forward and aft position of said pairs of elongated pleating fingers thereby varying the extent to which pairs of elongated pleating fingers project into the keys.
An apparatus for pleating paper comprising, a pair of pleating rollers, means to rotate one of said pleating rollers, each of said pleating rollers having a core shaft, each of said pleating rollers having a plurality of sets of keys, said keys being radially reduced sections and each set having at least two keys, a plurality of pairs of opposing elongated pleating fingers, a pair of opposing elongated pleating finger members positioned in each of at least a plurality of sets of keys, and means to movably support each of said elongated pleating finger members, and at least one support roller in peripheral supporting contact with a first roller of said pair of pleating rollers.
