[EX Q]: Person1: Could you explain the paper-making process to us - in very simple terms - please ?
Person2:Well , the pulp falls from a box onto the first part of the paper machine , which is basically a wire bed with large holes in it , where most of the water is extracted .
Person1: So , is it actually paper at this stage ?
Person2:Yes , it is . But we need to take out more water . So it then passes through a series of rollers , where more water is squeezed out . After that it goes through the dryers , which are at a very high temperature . The paper is then coated . And finally it's wound onto reels and cut down into smaller lengths .
