Definitions
- This invention relates to a process of roll-patterning and then optionally painting a surface of a metal strip or sheet, particularly an aluminium strip or sheet used to form vanes or head or bottom rails for window covering assemblies, such as venetian blinds, or to form architectural panels for ceilings or wall coverings.
- This invention particularly relates to an optionally painted metal strip or sheet with a decorative pattern on at least one surface, made by the process, and to a window covering assemblies and architectural panels made from the strip or sheet.
- Elongated vanes or slats of the type used in horizontal and vertical blinds are well known and commercially available.
- Such slats are formed, for example, by continuous casting of aluminium strips or sheets, subsequent milling and, if necessary, cutting to width to provide coils of aluminium strips having the desired thickness and width. Subsequently, the strips or sheets are painted (optional), then roll-formed and cut into slats of the desired length.
- coiled strip used to make blind slats, is normally covered with paint or lacquer in a coil-coating process in order to give it a decorative pattern before it is roll-formed into slats.
- a pattern can then be rolled into the painted strip surface, so that the resulting indentations in the strip surface give it a fabric-like appearance.
- An example of a process and apparatus for providing such a pattern in a painted strip surface for foldable metal drape panels for vertical blinds is described in US patent 4,362,039 (Toti).
- a rotary die is used to produce continuous patterns of scribe lines in painted surfaces of strips. The scribe lines assist in subsequently forming a preselected cross-sectional profile of the metal drape panels.
- Another rotary die is used for subsequently forming patterns of embossments in the strips between the scribe lines, in order to begin to stretch and work the metal between the scribe lines, so as to make it easier thereafter to form a weave pattern.
- weave patterns comprise relatively deep cuts which slice through the metal at the edges of the pattern and provide a raised area which imitates the ins and outs of woven threads of cloth. Unfortunately, these cuts tend to damage the paint on the strip surface and can result in premature corrosion of the metal.
- US patent 4,499,938 also describes a process and apparatus for making a metal blind slat by providing a relatively deeply embossed rib pattern in a painted strip material.
- the depth of the pattern is described as 0.381 mm 0.015 inch in a strip of 0.20 - 0.254 mm 0.008 - 0.010 inch thickness. This means that the depth of the pattern is more than the thickness of the strip, and so, the strip has been corrugated.
- such an embossed pattern also inevitably tends to damage the paint on the strip and produce premature corrosion of the metal.
- US 5,552.235 upon which the precharacterizing portion of appended claim 1 is based, describes an embossed cold rolled metal (e.g. steel) sheet for use in manufacturing appliances and method of makng same wherein the surface attributes of the embossed sheet are optimized to improve corrosion resistance of the painted product, promote uniform paint coverage of the sheet surface, reduce paint consumption, enable repainting without loss of pattern crispness, and provide consistent and aesthetically pleasing appearance of the painted sheet.
- embossed cold rolled metal e.g. steel
- the embossed sheet has a plurality of plateaus and impressions defined therein in a manner such that the arithmetic average surface roughness (Ra) of the plateaus is from about 1,27 - 2,54 micrometers (about 50 to 100 microinches), the maximum impression depths over a given area are from about 0,063 to 0,081 mm (about 0.0025 to 0.0032 inches), the impression walls define maximum slopes of from about 8-17 degrees, and there are no sharp corners or ridges at the transition points between plateaus and impressions.
- Ra arithmetic average surface roughness
- US 3,955,261 describes a panel of nonferrous metal sheet for covering facings, particularly a panel consisting of aluminium metal sheet, characterized in that said panel has an embossed surface provided with irregular areal depressions predominantly having a width of at least 10mm and depth of 10 to 30%, preferably approximately 25%, of the greatest panel thickness, the total area of the depressions corresponding to 20 to 50%, preferably to approximately 25%, of the whole panel surface, and that the rear side of the panel is flat.
- a decorative roll-patterned metal strip or sheet preferably an aluminium strip or sheet, is provided that has a thickness of about 0.05 - 1.0 mm, preferably about 0.1 - 0.8 mm, with a surface having a plurality of indentations of a depth of about 0.001 - 0.05 mm, preferably about 0.02 - 0.035 mm; the ratio of the depth of the indentations to the thickness of the strip or sheet being in the range of about 1: 5 to about 1: 100.
- the strip or sheet has a layer of a paint of a thickness of about 3 - 30 microns, preferably about 10 - 15 microns, on the surface and within its indentations.
- the indentations form a pattern which covers substantially the entire surface of the strip or sheet and which is visible to the naked eye, even when paint is within and atop the indentations.
- a process for making the decorative roll-patterned metal strip comprising the steps of:
- the process further comprises the step of subsequently painting the surface of the roll-patterned strip or sheet with a thickness of about 3 - 30 microns, preferably about 10 - 15 microns, of paint on the surface and within its indentations.
- the cold-rolling step using the milling roll with the surface pattern is carried out in a last stand of a multi-stand cold-roll mill, and only the last stand has at least one of its milling rolls with the surface pattern.
- Subsequent painting of the strip or sheet is preferably carried out in a separate machine for coil-coating.
- vanes and head and bottom rails for window covering assemblies such as venetian blinds, and architectural panels for ceilings or wall coverings made from the decorative roll-patterned strip or sheet of the invention.
- Figure 1 shows a five-stand cold roll reducing mill 1 for milling and roll-patterning a strip or sheet, such as an aluminium strip 2, in accordance with this invention.
- the strip 2 enters the mill 1 still in a ductile state following conventional heating and quenching steps.
- the five stands 3, 5, 7, 9 and 11 of the mill 1 sequentially reduce the thickness of the aluminium strip 2 in a conventional manner by simultaneously pressing with opposed top and bottom, steel, milling or working rolls, generally 13 and 15, on the top and bottom surfaces 17 and 19 of the strip 2.
- the last stand 11 has one or both of its top and bottom, milling rolls 13A and 15A with patterned surfaces in contact with the strip 2 to provide roll-patterned indentations 21 in one or both of the adjacent surfaces 17 and 19 of the strip 2.
- the temperature of the strip 2 is generally 40° - 175°C, preferably 75° - 120°C.
- the thickness of the strip 2 is preferably reduced in the last stand 11 by 15 - 40 %, preferably 20 -30%, to a thickness of 0.05 - 1.0 mm, preferably 0.1 - 0.8 mm., especially 0.1 - 0.3 mm for making slats and 0.4 - 0.7 for making head or bottom rails.
- the top surface 17, the bottom surface 19 or both of the strip 2 are roll-patterned by the patterned surface of the adjacent top and/or bottom, milling rolls 13A and 15A of the last stand 11 as shown in Figures 3A -3C.
- the strip 2 is still in a ductile state when it reaches the last cold roll stand 11 so that it is easier to roll-pattern the surface of the strip to provide a plurality of indentations 21 therein to a depth of 0.001 - 0.05 mm, preferably 0.02 - 0.035 mm, with the ratio of the depth of the indentations 21 to the thickness of the strip 2 being in the range of 1: 5 to 1: 100.
- depth of indentations is meant the depth of the indentations 21 in the strip 2 relative to the mean thickness of the strip 2 after roll-pressing in accordance with this invention.
- the ratio of the depth of the indentations 21 to the thickness of the roll-patterned strip 2 is no more than 1:10, particularly no more than 1: 16, and no less than 1: 50, particularly no less than 1 : 40.
- the roll-patterning of this invention does not corrugate the strip 2 but takes place only on its surface, so that the so-formed indentations 21 are accommodated entirely within the thickness of the strip.
- a pattern C on the surface of either the top or bottom, milling roll 13A or 15A of the last stand 11 can be rolled only into the adjacent top or bottom surface 17 or 19 of the strip 2 ( Figure 3A). This is often preferred for a strip 2 that is later to be roll-formed in a conventional manner into head or bottom rails for window covering assemblies or into architectural panels.
- a pattern C on the surface of both the top and bottom, milling rolls 13A and 15A of the last stand 11 can be rolled simultaneously into both the adjacent top and bottom surfaces 17 and 19 of the strip 2 ( Figure 3B). This is often preferred for a strip 2 that is later to be roll-formed into horizontal or vertical slats for window covering assemblies which have both sides visible in use.
- a pattern C on the surface of top milling roll 13A of the last stand 11 can be rolled into the adjacent top surface 17 of the strip 2, and a different pattern D on the surface of the bottom milling roll 15A of the last stand 11 can simultaneously be rolled into the adjacent bottom surface 19 of the strip 2 ( Figure 3C).
- Figure 2 shows the five-stand cold roll reducing mill 1 from above.
- the strip 2 enters at stand 3 and is milled through stands 3-11.
- the last stand 11 is the cold mill stand with one or two patterned milling rolls 13A and/or 15A.
- Strip 2 exits stand 11 with pattern C from the patterned rolls on its surface and is then led to roll-up stand 23.
- Figure 3A shows cold mill stand 9 and its pair of conventional milling rolls 13 and 15 and cold mill stand 11 and its pair of a top milling roll 13A with pattern C on its surface and a conventional bottom milling roll 15.
- the thickness of strip 2 is reduced in stand 11, and it exits stand 11 with the pattern C on its top surface 17.
- Figure 3B shows cold mill stand 9 and its pair of conventional milling rolls 13 and 15 and cold mill stand 11 and its pair of a top milling roll 13A and bottom milling roll 15A, both with pattern C on their surfaces.
- the thickness of strip 2 is reduced in stand 11, and it exits stand 11 with the pattern C on its top and bottom surfaces 17 and 19.
- Figure 3C shows cold mill stand 9 and its pair of conventional milling rolls 13 and 15 and cold mill stand 11 and its pair of a top milling roll 13A with pattern C on its surface and a bottom milling roll 15A with pattern D on its surface.
- the thickness of strip 2 is reduced in stand 11, and it exits stand 11 with the pattern C on its top surface 17 and the pattern D on its bottom surface 19.
- Figure 4 is a cross-section of a roll-patterned strip 2 of this invention as made, for example, in the mill stand 11 of Figure 3A.
- Figure 4 shows that the cold roll-patterning process, carried out in mill stand 11, does not corrugate the strip 2.
- Strip 2 has pattern C on the top surface 17 and a different pattern D on the bottom surface 19.
- the depth of the indentations 21 of each roll-pattern C and D is between 0.001 and 0.05 mm and preferably between 0.02 and 0.035 mm.
- each surface 17 and 19 can be painted, using conventional coating rollers and heat-curing techniques of coil-coating processes, without losing the appearance of its roll-pattern C or D.
- Figures 5A -5E show examples of some of the different roll-patterns that can be provided on the surface(s) of strip 2. In fact, there is an endless variety of possible patterns. Changing the pattern simply entails putting in a differently patterned milling roll 13A or 15A in the last stand 11 of the cold rolling multi-stand mill 1.
- Figure 5A shows a lattice-like pattern.
- Figure 5B shows a fish-grate wavy like pattern.
- Figures 5C and 5E show lettering patterns.
- Figure 5D shows a figurine-like pattern.
- the strip 2 can be rolled up in a conventional manner on roll 23 and allowed to cool.
- the roll-patterned surface(s) 17 and or 19 of the strip 2 can then be painted in a conventional manner with a thickness of 3 - 30 microns, preferably 10 - 15 microns, of paint on the surface(s) and within the indentations 21.
- each roll-patterned surface 17 and/or 19 of the strip 2 can be passed over a conventional paint applicator roller as described in the patent publications: EP 0 070 705 and U.S. 3 068 119.
- the painted strip 2 can be roll-formed in a conventional manner to form elongated horizontal or vertical slats or head or bottom rails for window covering assemblies, such as venetian blinds, or to form architectural panels for ceilings or wall coverings.
- the painted and roll-patterned 2 can be passed between conventional forming rolls as described in the patent publications: U.S. 4 173 879, U.S. 4 145 905, U.S. 3 26724, U.S. 2 692 003, U.S. 2 518 846, U.S. 2 471 490, U.S. 2 346 990 and U.S. 2 313 111.
