Method of making squeezing roll and squeezing equipment

Claim 1

A method of manufacturing a squeezing roll, said method comprising: (a) forming a plurality of through holes at a fixed spacing around the center of a plurality of thin circular plates; (b) stacking said plurality of thin circular plates together such that said through holes are aligned to provide continuous through holes which mutually pass through the stacked thin circular plates; and (c) forming a plurality of grooves by chemical etching on one surface or both surfaces extending from the outer circumferential edge of said thin circular plates to said continuous through holes to provide microholes which extend from the outer circumferential edge to said continuous through holes of the stacked thin circular plates.

Claim 2

A method of manufacturing a squeezing roll, said method comprising: (a) forming a plurality of through holes at a fixed spacing around the center of a plurality of thin circular plates; (b) stacking said plurality of thin circular plates together such that said through holes are aligned to provide continuous through holes which mutually pass through the stacked thin circular plates; and (c) forming a plurality of grooves by chemical etching on one surface or both surfaces extending from the outer circumferential edge of said thin circular plates to said continuous through holes to provide microholes which extend from the outer circumferential edge to said continuous through holes of the stacked thin circular plates.

Claim 4

A method of manufacturing squeezing equipment, said method comprising: forming a squeezing roll by (a) forming a plurality of through holes at a fixed spacing around the center of a plurality of thin circular plates; (b) stacking said plurality of thin circular plates together such that said through holes are aligned to provide continuous through holes which mutually pass through the stacked thin circular plates; and (c) forming a plurality of grooves by chemical etching on one surface or both surfaces extending from the outer circumferential edge of said thin circular plates to said continuous through holes to provide microholes which extend from the outer circumferential edge to said continuous through holes of the stacked thin circular plates; providing a second roll having its circumferential surface opposed to a circumferential surface of said squeezing roll such that an object to be compressed may be passed between said squeezing roll and said second roll, and providing a pressure conductive element on a side of said squeezing roll such that a frontal opening of said pressure conductive element is opposed on the locus of said continuous through holes on the side of said squeezing roll so that said continuous through holes pass adjacent to said frontal opening as said squeezing roll and said second roll rotate.

Claim 5

A method of manufacturing squeezing equipment, said method comprising: forming a squeezing roll by (a) forming a plurality of through holes at a fixed spacing around the center of a plurality of thin circular plates; (b) stacking said plurality of thin circular plates together such that said through holes are aligned to provide continuous through holes which mutually pass through the stacked thin circular plates; and (c) forming a plurality of grooves by chemical etching on one surface or both surfaces extending from the outer circumferential edge of said thin circular plates to said continuous through holes to provide microholes which extend from the outer circumferential edge to said continuous through holes of the stacked thin circular plates; providing a second roll having its circumferential surface opposed to a circumferential surface of said squeezing roll such that an object to be compressed may be passed between said squeezing roll and said second roll, and providing a pressure conductive element on a side of said squeezing roll such that a frontal opening of said pressure conductive element is opposed on the locus of said continuous through holes on the side of said squeezing roll so that said continuous through holes pass adjacent to said frontal opening as said squeezing roll and said second roll rotate.

Claim 9

A method of manufacturing squeezing equipment, comprising: providing a pair of squeezing rolls having opposed circumferential surfaces such that an object can pass therebetween to be compressed; forming each of said squeezing rolls by (a) forming a plurality of through holes at a fixed spacing around the center of a plurality of thin circular plates; (b) stacking said plurality of thin circular plates together such that said through holes are aligned to provide continuous through holes which mutually pass through the stacked thin circular plates; and (c) forming a plurality of grooves by chemical etching on one surface or both surfaces extending from the outer circumferential edge of said thin circular plates to said continuous through holes to provide microholes which extend from the outer circumferential edge to said continuous through holes of the stacked thin circular plates; and providing a pressure conductive element on each side of said pair of squeezing rolls such that a frontal opening of said a pressure conductive element is opposed on the locus of said continuous through holes on the side of said squeezing rolls so that said continuous through holes pass adjacent to said front opening as said squeezing rolls rotate.

Claim 10

A method of manufacturing squeezing equipment, comprising: providing a pair of squeezing rolls having opposed circumferential surfaces such that an object can pass therebetween to be compressed; forming each of said squeezing rolls by (a) forming a plurality of through holes at a fixed spacing around the center of a plurality of thin circular plates; (b) stacking said plurality of thin circular plates together such that said through holes are aligned to provide continuous through holes which mutually pass through the stacked thin circular plates; and (c) forming a plurality of grooves by chemical etching on one surface or both surfaces extending from the outer circumferential edge of said thin circular plates to said continuous through holes to provide microholes which extend from the outer circumferential edge to said continuous through holes of the stacked thin circular plates; and providing a pressure conductive element on each side of said pair of squeezing rolls such that a frontal opening of said a pressure conductive element is opposed on the locus of said continuous through holes on the side of said squeezing rolls so that said continuous through holes pass adjacent to said front opening as said squeezing rolls rotate.
