Definitions

• the present invention relates to a wide adhesive sheeted roll for contact cleaning. More particularly, the present invention relates to a wide adhesive sheeted roll for contact cleaning and a method of manufacturing the wide adhesive sheeted roll using an adjustable dead-stop to control the position of a tension roller.
• Contact cleaning is used to clean substrate surfaces. Once cleaned the substrate surfaces may be used in a variety of sophisticated processes such as in the manufacturing of electronics, photovoltaics and flat panel displays.
• a rubber or elastomeric cleaning roller is used to remove contaminating particles from a substrate surface and an adhesive sheeted roller can then be used to remove the contaminating particles from the cleaning roller. This allows the cleaning roller to maximise its efficiency in removing contaminating particles.
• an apparatus capable of manufacturing a wide adhesive sheeted roll for contact cleaning, said apparatus comprising:
• a rotatably mounted path roller located below the tension roller
• the rotatably mounted tension roller having ends which are height adjustable;
• the present invention therefore relates to an apparatus capable of manufacturing a wide adhesive sheeted roll for contact cleaning where an upper located rotatably mounted tension roller is capable of having its height adjusted during use and therefore ensuring that a constant or substantially constant pressure is applied to a web which forms adhesive sheeted rolls. This allows high quality adhesive sheets to be formed. This significantly advantageous feature allows wider adhesive sheeted rolls to be formed than was previously possible with apparatus comprising fixed ends for the tension roller.
• the apparatus of the present invention may be capable of forming wide adhesive sheeted rolls with a width of greater than about 1 .5 m and optionally up to about 2.2 m or even higher.
• the rotatably mounted tension roller may therefore be capable of adjusting its height during the feeding of the adhesive web between the counter-rotating tension roller and path roller.
• the height adjustment may be achieved by using any suitable means that allows both ends of the tension roller to vary in height.
• the height adjustable means may also comprise adjustable dead-stop mechanisms which are capable of limiting the amount of vertical travel for either end of the tension roller.
• the height adjustable means may comprise a back-plate onto which all component parts of the dead-stop mechanism may be mounted.
• the height adjustable means may comprise a movable jaw which is capable of moving up and down.
• the movable jaw may be connected to an arm which may be spring activated and which allows movement of the movable jaw and is also capable of moving up and down with the movable jaw.
• the arm may be connected to a lever capable of articulating about a pivot point on the back-plate.
• the height adjustable means may therefore comprise a dead-stop which controls and limits the amount of vertical travel of the movable jaw.
• the vertical position of the movable jaw and the dead-stop may also be adjusted in a vertical slot to obtain the optimum operating conditions and to provide a constant or substantially constant pressure across the adhesive web.
• the apparatus may also comprise rotatable shafts onto which the tension roller and the path roller may be mounted.
• the tension roller may be substantially cylindrical in shape and may be located above the path roller which may also be substantially cylindrical in shape.
• the apparatus may also comprise a brake to control the feed rate of the web.
• a method of manufacturing a wide adhesive sheeted roll for contact cleaning comprising using an apparatus comprising:
• a rotatably mounted path roller located below the tension roller
• the rotatably mounted tension roller having ends which are height adjustable; wherein there is a gap between the rotatably mounted tension roller and the rotatably mounted path roller capable of receiving a web and forming a wide adhesive sheeted roll.
• the apparatus may be as defined in the first aspect.
• the method may also produce wide adhesive sheeted rolls with a width of greater than about 1 .5 m and optionally up to about 2.2 m or even higher.
• Figure 1 is a perspective front view of an apparatus capable of manufacturing wide adhesive sheeted rolls for contact cleaning according to an embodiment of the present invention
• Figure 2 is a perspective rear view of the apparatus shown in Figure 1 ;
• FIG 3 is an expanded view of an adjustable dead-stop mechanism used in the apparatus shown in Figures 1 and 2.
• FIG 1 is a representation of an apparatus capable of manufacturing wide adhesive sheeted rolls generally designated 100.
• the apparatus 100 comprises a tension roller 1 10 and a path roller 1 12.
• the tension roller 1 10 is substantially cylindrical in shape and is located above the path roller 1 12 which is also substantially cylindrical in shape.
• a wide adhesive web 1 14 is fed through a gap between the counter-rotating tension roller 1 10 and path roller 1 12.
• Figure 1 also shows that the apparatus comprises a brake 1 16.
• Figure 2 is a perspective rear view of the apparatus 100 and shows the wide adhesive web 1 14 being fed through a gap between the tension roller 1 10 and the path roller 1 12.
• Figure 2 also shows that on each side of the apparatus 100 there are adjustable dead-stop mechanisms 1 18.
• the adjustable dead-stop mechanism 1 18 shown in the right-hand side of Figure 2 is circle with dashed line 'A' and is shown in an expanded form in Figure 3.
• FIG 3 shows that the dead-stop mechanism 1 18 comprises a back-plate 120 onto which all component parts of the dead-stop mechanism 1 18 are mounted.
• the tension roller 1 10 is shown rotatably mounted to a movable jaw 122 which is capable of moving up and down. This will be discussed in more detail below.
• the movable jaw 122 has a lower bottom surface 123.
• the arm 124 comprises an upper member 126 which is spring activated and connected to the movable jaw 122 at connection point 128.
• a lower member 125 On the bottom part of the arm 124 there is a lower member 125 which receives the upper member 126 and is able to move the height and location of the movable jaw 122.
• the lower end 130 of the arm 124 is connected to a lever 132 capable of articulating about pivot point 134 on the back-plate 120.
• Figure 3 also shows that there is a block 136 with a dead-stop 138 mounted on top of the block 136. There is shown a gap generally designated 140 between the dead-stop 138 and the bottom surface 123 of the movable jaw 122. The jaw 122 can therefore move within the gap 140 in a substantially vertical manner. There is also shown a vertical slot 142 within which the height and vertical location of the movable jaw 122 and dead-stop 138 are capable of being adjusted.
• the adhesive web 1 14 is fed between the tension roller 1 10 and the path roller 1 12.
• the brake 1 16 may be used to control the feed rate of the web 1 14.
• the upper located tension roller 1 10 is capable of adjusting its vertical position along the direction shown by the vertical line B - C.
• the height and position of the tension roller 1 10 is capable of constantly adjusting using the movable jaw 1 18 and the amount of vertical travel being controlled by the adjustable dead-stop 138, this allows a constant or substantially constant pressure to be applied across the web 1 14.
• This feature of the apparatus 100 of the present invention allows a much wider adhesive web 1 14 to be formed than was previously possible.
• the apparatus 100 of the present invention is capable of forming greater than about 1 .5 m wide adhesive sheeted rolls and up to about 2.2 m or even higher. Whilst specific embodiments of the present invention have been described above, it will be appreciated that departures from the described embodiments may still fall within the scope of the present invention. Moreover, any suitable type of mechanism which allows the height of an upper tension roller to adjust during the manufacturing process of a wide adhesive web may be used.
