Abstract
Abstract The machine for cooling metal sheets or plates comprises a casing having at least two parallel planar portions in facing relation to each other and defining therebetween a gap whose width exceeds the thickness of the sheet to be cooled so as to define two chambers with the sheet. A series of sheet guide and support rollers extend transversely of the longitudinal direction of the sheet. The casing comprises part-cylindrical portions surrounding the rollers and the planar portions are disposed between two adjacent ones of the rollers which are located on the same side of the sheet. Cooling water is supplied to the chambers and flows in a direction substantially parallel to the plane of the sheet.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
132 words
A machine for cooling metal sheets or plates, comprising a casing having at least two substantially planar and substantially parallel portions in facing relation to each other and defining therebetween a gap having a width which exceeds the thickness of the sheet to be cooled so as to define two chambers with the sheet, means for supplying said chambers with a current of cooling water which moves substantially in a direction substantially parallel to the plane of the sheet, a series of parallel sheet support and guide rollers which are disposed transversely of the longitudinal direction of the sheet, said substantially planar portions being disposed between two adjacent rollers of said rollers which are located on the same side of the sheet, the casing further comprising substantially partcylindrical portions surrounding said rollers.
Claim 2
Dependent Claim
132 words
A machine for cooling metal sheets or plates, comprising a casing having at least two substantially planar and substantially parallel portions in facing relation to each other and defining therebetween a gap having a width which exceeds the thickness of the sheet to be cooled so as to define two chambers with the sheet, means for supplying said chambers with a current of cooling water which moves substantially in a direction substantially parallel to the plane of the sheet, a series of parallel sheet support and guide rollers which are disposed transversely of the longitudinal direction of the sheet, said substantially planar portions being disposed between two adjacent rollers of said rollers which are located on the same side of the sheet, the casing further comprising substantially partcylindrical portions surrounding said rollers.
Claim 3
Dependent Claim
22 words
A machine as claimed in claim 1, wherein the water is supplied and discharged in at least some of said part-cylindrical portions.
Claim 4
Dependent Claim
31 words
A machine as claimed in claim 1, wherein the water is supplied and discharged in at least some of regions of the casing which are located between two sets of rollers.
Claim 5
Dependent Claim
41 words
A machine as claimed in claim 1, wherein the rollers are hollow and include radial passages which put the interior of the rollers in communication with the periphery of the rollers and through which passages the water is supplied and discharged.
Claim 6
Dependent Claim
43 words
A machine as claimed in claim 1, comprising deflectors in the vicinity of regions of connection between the planar portions and the part-cylindrical portions of the casing, said deflectors extending from said connection regions toward a sheet-receiving gap between adjacent and corresponding rollers.
Claim 7
Dependent Claim
14 words
A machine as claimed in claim 5, wherein the deflectors are adjustable in position.
Claim 8
Dependent Claim
22 words
A machine as claimed in claim 1, wherein the gap defined between the planar portions of the casing is adjustable in width.
Claim 9
Dependent Claim
21 words
A machine as claimed in claim 1, wherein the guide rollers are hollow for receiving a flow of cooling fluid therethrough.
Claim 10
Dependent Claim
29 words
A machine as claimed in claim 1, wherein the casing is metallic and includes a jacket in at least its planar portions for receiving a supply of cooling fluid.
Claim 11
Dependent Claim
21 words
A machine as claimed in claim 1, adapted to receive sheets of different widths, the water supply means being correspondingly adjustable.
Claim 12
Dependent Claim
41 words
A machine as claimed in claim 1, wherein the means for supplying the water are located in the vicinity of a longitudinal median plane of the sheet and means for discharging the water are located alongside the edges of the sheet.
Claim 13
Dependent Claim
25 words
A machine as claimed in claim 1, wherein the means for supplying the water are located alongside each one of the edges of the sheet.
