Selecting a paper-making machine

Factors to consider when selecting a paper-making machine

Experience and reputation of the manufacturer

The experience of a manufacturer is essential to businesses because it can indicate that the manufacturer’s products are of good quality. Manufacturers developing papermaking machines for a long time will have learned what the industry demands, and will create machines that meet these requirements. Some reputable manufacturers that businesses could choose from include Technocarton, Burgo Benelux, and Toscotec SPA.

Cost

The cost of the machine will vary depending on the technology used, the machine’s output, and its size. Paper machines cost from as low as US $9000 to US $97000. Therefore, businesses should select machines that they can afford, which can still satisfy their needs.

Ease of operation and maintenance

Some paper-making machines may be easy to use, while other machines may not be easy to use. When purchasing a paper-making machine, businesses should first find out whether they are easy to use. Getting a technician from the manufacturer could be helpful to them too. In addition, businesses should enquire on how maintenance of the machine should be carried out as well as the availability of the spare parts. The business could also request training of personnel.

Safety

Businesses should purchase machines with good safety features to ensure the operators’ safety. Machines should be operated in rooms that have adequate space to avoid being clipped by nips and pinch points. The correct procedure should always be used when running the machine. Personnel should also be well dressed in protective equipment such as eyewear, ear muffs, overall/coat, and safety boots.

Productivity

Production capacity is the amount of paper produced per unit of time. It is measured in meters per minute, and it varies from machine to machine. Some machines have a production capacity of 200m/min, while others have a capacity of 300m/min. Businesses should select machines with an output that suits their production needs.

Paper size

Paper-making machines have different paper dimensions that they manufacture. The paper width depends on the use of the business. Available paper widths include 1600mm, 1800mm, and 2640mm. Businesses should select the appropriate paper width depending on the needs of their clients.

Features of a paper-making machine

The headbox

The headstock receives the mixture of pulp and holds it before it’s taken through filtration. Three things are done in the headbox: breaking up pulp blocks by turbulence, ensuring flow distribution through the paper machine, and controlling the velocity of the jet leaving the headbox by the pressure in the headbox. This allows the pulp to flow through several rotating perforated rolls. The pulp, also called the stock, leaves the headbox as a free jet onto the forming screen where the filtration process begins.

The forming section

The pulp goes through the fourdrinier table, a series of vacuum boxes, and a couch roll. On the fourdrinier table, the pulp is drained of water by being placed on a forming wire with foils under it. The vacuum boxes help flatten the top surface of the pulp (now a sheet) and improve its finish. While on the couch roll, more water is removed from the sheet.

The dryer

The paper leaves the press section and goes into the dryer at a consistency of 40-45%. The dryer has 40 to 70 steam dryer cylinders that remove more water by evaporation. Dryer felts are used to hold the heated surfaces.

The calendering

In calendaring, the paper is passed through the calendar stack. The calendar stack is a vertical stack of solid iron rolls. The iron rolls impart higher compression cycles to the paper. The calendar stack reduces the thickness of the paper. It also makes the paper more printable by increasing the smoothness of the paper.

The press section

In the press section, water is squeezed from the wet web. This increases the solid content and reduces the thickness of the paper. It also helps improve the bonding of the fibers.

Reel

The paper web is wound on a large roll known as a reel in preparation for storage. Calendering and the reel are among the last stages of paper making.

Winder

From the winder, the paper is unwound and cut into different sizes according to the client’s specifications.
