Definitions
- the present invention makes it possible to provide a compact coating facility with a short drying section that can readily be retro-fitted into an existing roll-forming line or can be economically fitted into a new roll-forming line.
- the coating has non-slip characteristics when dry.
- the method includes controlling, for example by limiting, the application of roll-forming lubricant or the volume of applied roll-forming lubricant so as not to adversely affect the efficacy or integrity of the least partially dried or partially cured coating.
- the method includes passing the strip along the roll forming line at a line speed of at least 3 Om/min .
- the line speed is up to 5Om/min.
- the method includes passing the strip from an uncoiler to the first roll-former stand in a time period of less than 10 seconds.
- a profiled steel decking sheet suitable for use as formwork in the construction of a composite concrete slab that includes: one upstanding rib or a plurality of parallel upstanding ribs that extend along the length of the sheet, pans that separate the rib or ribs, and a coating (i) on the pans or. (ii) on the rib or ribs or (iii) on the pans and on the rib or ribs, that reduces the overall glare of the sheet and highlights the presence of the ribs .
- the coating may be restricted to the pans, it may partially cover the sides of the main ribs, or it may wholly cover the sides of the main ribs .
- a roll forming line for manufacturing profiled steel decking sheets that are suitable for use as formwork in the construction of composite concrete slabs, the line including:
- a series of roll former stands for progressively roll forming the coated strip to form parallel ribs extending from the plane of the strip;
- the coating assembly includes a roller coater assembly.
- the roller coater assembly includes a roll for picking up coating from a reservoir, an applicator roll for transferring coating from the pick-up roll to a surface of the strip and thereby forming the coating on the strip.
- the applicator roll has a series of raised lands that extend around the circumference of the roll at spaced intervals along the length of the roll whereby the lands define surfaces for transferring coating from the pick-up roll to the strip to form a series of spaced apart lengthwise extending coating bands on sections of the strip that form the pans of the profiled steel decking sheets.
- the applicator roll does not coat the sections of the strip that form the rib or ribs of the sheets. In some instances the sides of the rib or ribs may be partially or wholly coated.
- the applicator roll is arranged to be driven by contact with the strip and the pick-up roll is arranged to be driven by contact with the applicator roll.
- roller coater assembly further includes a scraper member for scraping coating from the pick-up roll upstream of the applicator roll and thereby controlling the coating thickness on the pick-up roll.
- the scraper member is adjustable.
- the drying means includes a first heated air blower between the coating assembly and a first roll forming stand.
- the drying means includes a second heated air blower between roll forming stands that are downstream of the first roll forming stand in the direction of movement of the strip along the line.
- the drying means includes a heated chamber between the coating assembly and a first roll forming stand through which the coated strip passes prior to reaching the first roll forming stand.
- the drying means includes infra-red heating means between the coating assembly and a first roll forming stand through which the coated strip passes prior to reaching the first roll forming stand.
- the drying means includes a means for supplying heated air to the chamber.
- the roll forming line includes a means for controlling the amount of lubricant applied to the strip during roll- forming to prevent excessive contact between the coating and the roll-forming lubricant.
- the roll forming line may include means, such as felt pads, to remove excess lubricant off the roll forming rolls or off the strip during the roll-forming operation.
- a roller coater assembly for forming a coating on at least one surface of a steel strip which includes a roll for picking up coating from a reservoir, an applicator roll for transferring coating from the pick-up roll to a surface of the strip and thereby forming the coating.
- the applicator roll is adapted to be driven by contact with the strip and the pick-up roll is adapted to be driven by contact with the applicator roll .
- roller coater assembly further includes a pressure roll for contacting the opposite surface of the strip to that contacted by the applicator roll to force the strip against the applicator roll.
- roller coater assembly further includes a scraper member for scraping coating from the pick-up roll upstream of the applicator roll and thereby controlling the coating thickness on the pick-up roll.
- the scraper member is adjustable.
- Figure 1 is a side elevation of one embodiment of a roll forming line in accordance with the present invention.
- the coated pans 5 substantially reduce the overall glare resulting from the sheet.
- selectively coating the pans 5 and leaving the ribs 3 uncoated has the effect of highlighting the location of the ribs 3.
- the location of the ribs 3 is highlighted by the difference between the glare of the ribs 3 and the glare of the pans 5.
- the location of the ribs 5 is further highlighted by appropriate selection of the colour of the coating.
- the roll forming line shown in Figure 1 includes an uncoiler 23 that holds a coil 25 of zinc coated steel strip so that the strip 71 can be unwound from the coil as a flat sheet and passed successively to and thereafter through a roller coater assembly 11 and a series of conventional roll-former stands 9.
- the roller coater assembly 11 forms a coating on the lower surface of the flat strip as the strip moves along the line prior to the strip reaching the roll former stands 9.
- the roll coater assembly 11 is described in more detail hereinafter with reference to Figures 2 to 5.
- the roller coater assembly 11 further includes a roll 35 that contacts the upwardly facing surface of the strip and applies downward pressure to the strip and thereby forces the strip against the applicator roll 33.
- the applicator roll 33 has a series of lands 37 that extend around the circumference of the roll at spaced intervals along the length of the roll.
- the lands 37 define surfaces that transfer coating from the pick-up roll 31 to the strip and form a series of spaced apart lengthwise extending coating bands on the sections of the strip that ultimately form the pans 5 of the profiled steel decking sheet shown in Figure 6.
- the arrangement is such that the applicator roll 13 does not transfer coating to the sections of the strip that ultimately form the top of the ribs 3 of the Figure 6 decking sheet.
- the roller coater assembly 11 further includes an adjustable scraper bar 39 that is positioned in relation to the pick-up roll 31 so that it removes excess coating from that roll 31 before the roll 31 rotates to the applicator roll 33.
- the scraper bar 39 is adjustable whereby the initial coating thickness on the pick-up roll 31 can be varied, as may be required.
- the scraper bar 39 provides an initial coating thickness control for the roll coater assembly. Further coating thickness controls are provided by the contact between the pick-up roll 31 and the applicator roll 33 and by the contact pressure of the applicator roll 33 and the strip.
- the first air blower 13 is positioned between the roller coater assembly 11 and the first roll- former stand 9 and is operated to substantially dry the coating before the strip reaches the first roll-former stand 9.
- the second air blower 15 is positioned between the third and fourth first- roll forming stands and is operated to complete the process of drying the coating.
- the chamber 45 includes an upstream inlet end 61 for wet coated strip 71 and a downstream outlet end 63 for dried coated strip 71.
- the strip 71 passes through the chamber 45 with the wet coating bands (identified by the numeral 75 in Figure 8) facing downwardly.
- the moving coated strip is supported in the chamber 45 by a series of guide rollers 47 on opposite sides of the strip, above and below the strip, within the chamber 45. The rollers are positioned so that there is no direct contact between the rollers and the wet coated strip moving through the chamber 45.
- the chamber 45 is heated by hot air that is supplied to downstream end of the chamber 45 via ductwork 77 and flows through manifolds 49 that extend along the length of the chamber and is discharged from the upstream end of the chamber 45 via ductwork 79.
- the manifolds 49 include openings 51 in the upper and side walls thereof that allow heated air to escape into the chamber 45 and contact the moving strip.
