Definitions
- a gypsum board stops for a few seconds before entering the dryer. Its cut end is positioned against a stop plate and then pressed.
- the invention relates to a process for the production of a hydraulic binder board having at least one tapered cut end, comprising the steps of: i) spraying a softening liquid on at least one cut end of the board ; ii) waiting for the softening liquid to penetrate the board ; and iii) applying pressure on said at least one cut end of said hydraulic binder board.
- the invention relates to a process for the production of hydraulic binder boards having tapered cut ends, comprising the steps of : a) moving at least one first hydraulic binder board having first and second cut ends on a conveyor until it reaches a pressing area ; b) moving at least one second hydraulic binder board having first and second cut ends on the conveyor until it reaches said pressing area and its first cut end contacts the second cut end of said at least one first hydraulic binder board ; c) applying pressure on first cut end of said at least one first hydraulic binder board ; d) applying pressure on both second cut end of said at least one first hydraulic binder board and first cut end of said at least one second hydraulic binder board ; and e) applying pressure on second cut end of said at least one second hydraulic binder board.
- a further object of the invention is a production line for hydraulic binder boards having at least one tapered cut end, comprising :
- Yet a further object of the invention is a production line for hydraulic binder boards, comprising :
- Figure 1 is a view in perspective elevation of a gypsum board production line according to this invention ;
- Figure 2 is a schematic view of the pressing area before the application of the compressive loads ;
- Figure 5 is a schematic perspective view of the pressing area showing the presses.
- the process for the production of gypsum boards further comprises steps to impart a taper to the cut end of a board.
- edge refers to the finished edge of the board extending parallel to the direction of board travel
- end refers to the cut end of the board extending transverse to the edges.
- the pressing is then located upstream from the dryer 15 with reference to the board travel (see Figure 1) .
- the steps a) to e) are carried out after the boards are dried.
- the pressing steps c) to e) are preceded by the steps of : i) spraying a softening liquid on at least the cut ends of the boards; and ii) waiting for the softening liquid to penetrate the boards i.e. the paper and the core of the boards .
- the production line therefore comprises means for spraying a softening liquid on at least the cut ends of the boards.
- These spraying means are located between the dryer 15 and the pressing area 31 or they may located in the pressing area 31. They may be conventional spraying means well known by those skilled in the art.
- the softening liquid may be water, alcohol, spirits, propylen glycol or any agent having a high vaporization speed.
- the process comprises a subsequent step in which the pressed boards are dried in an additional dryer (not shown) which may be a heated blower dryer or an infrared dryer.
- the production line comprises means for the obtention of tapered edges, for example a tapered edge belt which is placed along the edge of the continuous belt and extends beneath the setting gypsum board, tapering in thickness toward the center of the gypsum board (see for example Figure 5 of EP-A-482 810) .
- a tapered edge belt which is placed along the edge of the continuous belt and extends beneath the setting gypsum board, tapering in thickness toward the center of the gypsum board (see for example Figure 5 of EP-A-482 810) .
