Paper Sheet Forming Of Paper Machine

Paper is made from the processed stock on a papermaking machine . Ordinarily there are two kinds of machines used for making paper. The fourdrinier invented by Louis Robert in France in 1799 and commercialized in England in 1804; and the cylinder machine invented by John Dickinson of Germantown Pennsylvania in 1809. The fourdrinier section of papermaking machine is a framework, fabricated from steel, cald with a corrosion-resistant covering( usually stainless steel). This framework supports the wire, table rolls, stock save-all, suction boxes, and other fourdrinier parts.  The most important part of the fourdrinier is the wire, of finely woven metal cloth which allows drainage, but retains fiber. Fundamentally, its action may be described as follows: as the stock emerges from the slice the shorter fibers, filler, and other additives are deposited; the drainage and filtration by the fourdrinier wire leave the sheet as a uniform, homogeneous mass; strength in both the machine an...

The Paper Making Process

All of us use paper every day. Yet, few realize all of the steps necessary to change plant material to this common, every day product. The fact that mankind ever stumbled upon this process is shear genius as the paper making process follows three steps: preparation of the fibers, sheet formation, and drying. Paper pulping process During the first step of the paper making process, the material used to make the paper is converted to pulp, which is a concentrated mixture of fibers that are suspended in liquid. Generally, the fibers are those found naturally in softwood trees, hardwood trees, or other plants. The fibers can also come from recycled paper, such as from newsprint, old corrugated boxes, and mixed paper. The paper pulping process consist of paper pulping, pulp cleaning, pulp screening or pulp refining Paper Making Process The next step is sheet formation. At this stage in the process, the pulp mixture is diluted some more with water. This is then strained throug...

In an exclusive interview to ET NOW, AS Mehta, President, JK PaperBSE 1.22 % talks about the current scenario of the Indian paper market. Edited Excerpts: In the backdrop of the recent plant shutdowns in South India, what are your views on the demand scenario for the first half of the year? do you see yourselves servicing additional demand on the back of this shutdown? Demand has no connection with the shutdown of the plant in south India. It is a question of supplies. So as far as the demand is concerned, market is growing alright. As I had said previously, that the Indian paper market is the fastest growing paper market in the world and we are seeing a growth o around 6-7%. That is the demand side. As far as plants in South India are concerned, it is a supply problem which had come up due to the water scenario.The difficulties faced resulted in supply side being partially impacted. What is the outlook on raw material costs going forward, where do you see raw ...
