Definitions

  • This invention relates generally to gypsum board, and more specifically to methods and an apparatus for providing recessed portions on the lateral edges of wallboard.
  • Conventional gypsum wallboard or drywall is typically manufactured from a gypsum plaster slurry which is put between two layers of paper. More specifically, in the conventional method, a wet slurry of gypsum is poured on a conveyor between two layers of paper, and the slurry is allowed a certain amount of time to set. In gypsum wallboard, the two layers of paper contain the slurry and provide the tensile strength required in installation and use.
  • the conveyor is a closed loop conveyor that can travel at speeds of four hundred feet per minute or faster.
  • the conveyor enables the wallboard to be fabricated using rolls of paper and accordingly, includes at least a longitudinal edge forming system, a cutting system, and a drying system.
  • the edge forming system uses wedge shaped raised edges along the conveyor that create recessed areas along the longitudinal edges in the face of the wallboard prior to the wallboard being fully cured. When the wallboard is later cut to size and installed, the recesses are filled with wallboard compound, taped over, and finished to produce a smooth joint.
  • the cutting system enables the wallboard to be cut into predetermined discrete lengths such that substantially rectangular wallboard members are formed.
  • the cutting system is adjustable to allow different lengths of wallboard to be cut without substantial interruption of the manufacturing operation. After being cut, the wallboard members are moved away from the cutting station to a loading area where they are loaded into a drying system to dry the cut wallboard members.
  • Known wallboard includes recessed areas that extend along both of the opposed longitudinal edges of the wallboard.
  • the recessed areas are formed by the raised edges on the conveyor.
  • the recessed areas are in the shape of inclined planes that taper from the face of the wallboard to the longitudinal edges and have a maximum depth at the side edges of about 2.29 mm (0.090") below the face of the wallboard.
  • panels of conventional wallboard are formed which are bordered by the opposed recessed longitudinal edges and by a pair of lateral non-recessed edges that connect the longitudinal edges. More specifically, the wallboard is typically cut such that the panels are fabricated with a longitudinal length that is commonly eight feet, ten feet, twelve feet, fourteen feet, and sixteen feet or longer.
  • wallboard panels are made in thicknesses that are commonly 6.35 mm, 9.53 mm, 12.7 mm, 15.88 mm (1/4", 3/8", 1/2" and 5/8") thick.
  • wallboard panels are typically positioned for installation such that the longitudinal edges are parallel to the floor, an installation known as a "horizontal orientation". In this installation, a longitudinal recess of a first panel is adjacent to a longitudinal recess of the adjacent panel. This forms a longitudinal recessed joint.
  • a wallboard compound fill material and tape are then used to seal the recessed joint formed by the recessed longitudinal edges of the panels.
  • the recessed areas of the joints are filled with the wallboard compound, taped and smoothed across the joint, such that the joint is covered without the compound creating an unsightly bulge extending outwardly between the panels.
  • Installing the wallboard panels such that the longitudinal length extends horizontally along a wall parallel to the floor, rather than vertically and substantially perpendicularly to the floor facilitates faster installation time of the wallboard panels, and faster finishing time of the installed wallboard panels.
  • installation and labor costs may be increased as the installers and tapers must use ladders for installation and finishing.
  • a butt joint may be formed between the lateral edges of two adjacent panels.
  • Such joints must still be covered with tape and compound, but because the lateral edges do not include a recessed area, the joint compound must be spread over a wider area than those of the longitudinal joints to facilitate blending the butt joints into the wall surface without creating unsightly bulges.
  • the process comprises 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 with multiple presses.
  • the process comprises the steps of moving at least one first and one second hydraulic binder boards on a conveyor and applying pressure on the cut ends of said hydraulic binder boards with multiple presses.
  • the present invention comprises a method according to claim 1 as well as a method according to claim 6 and a device according to claim 12.

  • Fig. 12 is a side view of a length of wallboard passing through an upper and lower press assembly according to an embodiment of the present invention.
  • an embodiment of the present invention comprises a press 20 for forming of one or more recessed lengths in partially cured gypsum wallboard such that when the partially cured wallboard is cut into finished lengths, the lateral edges of the finished lengths have recessed edges on all four edges of the board.
  • a recess can be a tapered or non-tapered recess.
  • the invention preferably performs this press function in partially cured gypsum wallboard panels after gypsum slurry has been applied to paper backing but before the wallboard is sent to ovens to fully cure.
  • the recessed areas are formed along the lateral edges of the uncut wallboard and also in several locations along the length of the uncut wallboard.
  • the locations of the recesses on the length of the uncut wallboard will vary depending upon whether eight foot lengths, nine foot lengths, ten foot lengths, etc. of wallboard, or combinations of length thereof, are being produced.
  • the length of uncut and partially cured wallboard that is sent to ovens to be fully cured is 9.75 m (32'), although other lengths may be produced in various gypsum wallboard plants.
  • the 9.75 m (32') foot length, or other appropriate length, is referred to as the unfinished length.
  • a smaller number of presses are provided that are positionable on the support system to the various required locations. Additionally, the presses are easily removable so that a press may be removed for repair and maintenance.
  • recesses running the width are formed therein such that every common length of wallboard can be manufactured with lateral edge tapers at the finished wallboard lengths.
  • the presses 20 each comprise an upper press assembly 22 and a lower press assembly 24.
  • Wallboard 26 passes between the upper and lower press assemblies 22 and 24.
  • the upper press assemblies 22 are moveable from an upper position where the upper press assemblies 22 do not contact the uncut wallboard and a lower position where the upper press assemblies 22 come into contact with the uncut wallboard. Because the recesses are most preferably only about .090" deep, the upper press assemblies 22 are infinitely adjustable in the vertical direction such that fine adjustment can be made to adjust for tolerances in the thickness of the wallboard and also to accommodate wallboard of different nominal thicknesses.
  • the proper adjustment of the height of the upper press assembly may be detected by either a laser measure or by physically contacting the wallboard, for example with a roller that measures the precise thickness of the wallboard.
  • the upper presses 22 are all individually adjustable to properly control recess depth as the wallboard moves through the presses. As can been seen in Fig.I. four upper press assemblies 22 have been lowered in position at 0 m, 3.66 m, 6.71 m, (0', 12', 22') and 9.75 m (32') to make wallboard of 3.05 m (10') and 3.66 m (12') lengths.
  • Fig. 2 shows the upper press assembly 22, the lower press assembly 24 and a takeout conveyor 28 to remove the wallboard from the press.
  • An upper surface of the takeout conveyor 28 is preferably in a plane lower than the upper surface of the lower press assembly 24 so that the wallboard 26 will move away from the upper press assembly 22 as it exits the lower press assembly 24. Lengths of wallboard 26 are shown between the upper and lower press assemblies 22 and 24, and the press assemblies 22 and 24 and takeout conveyor 28 move the wallboard in a direction indicated by arrow A.
  • the upper press assembly 22 comprises two spaced apart plates 30 and 32 attached to one another to form an upper plate assembly 34. Riding upon the upper plate assembly 34 are a plurality of upper shoe assemblies 36. The upper shoe assemblies 36 are attached to one another end- to-end and form a loop around the upper plate assembly 34. A large sprocket 38 is located at a first end 40 of the plate assembly 36, and a small sprocket 42 is located at an opposite, second end 44 of the plate assembly 36. The sprockets are located between the plates 30 and 32. One or both of the sprockets 38 and 42 are powered to cause the upper shoe assemblies 36 to rotate about the upper plate assembly 34 in the direction shown by the arrows B.
  • shoe support bar 46 that maintains the upper shoe assemblies 36 adjacent the upper plate assembly 34 as the upper shoe assemblies 36 travel along the bottom portion of the upper plate assembly 34 until the upper shoe assemblies 36 are out of contact with the wallboard as they extend around the large sprocket 38, as further described below.
  • the lower press assembly 24 is shown in Fig. 4 and comprises first and second plates 48 and 50 attached to one another and spaced apart from one another to form a lower plate assembly 52 having a first end 56 and a second end 60.
  • Mounted upon the lower plate assembly 52 are a plurality of lower shoe assemblies 54.
  • the lower shoe assemblies 54 extend around the lower plate assembly 52 to form a loop.
