AS International Group

Stock Preperation

AS Group provides optimal process and carefully selected machines in accordance with the character and requirements of paper which will be produced. The process is designed and applied suitable for its application considering the various kinds of raw material. General process consists of the following partial processes together with relating machines for paper requirements.

In addition, AS Group supplies engineering service, which covers machine, process and electric & control engineering to produce quality product effectively and also provides supervision service for erection and start-up to assist customers to acquire good quality in a shorter period of time.

At AS Group, we employee leading world class expertise to process stock preparation systems.

AS Group has experienced the various process lines needed in stock preparation from bale handling to headbox approach system.

AS Group’s experience and skill always support you from initial planning to the whole project phase, and trough commissioning and start-up to continuous production.

AS Group is continuously developing solutions and processes to meet your needs with lower energy consumption and innovative use of raw materials.

OCC MAIN MACHINE

With many years of experience in OCC lines, AS Group products offer solutions with energy efficient and robust recycling of recovered paper.

AS Group consider OCC stock preparation not only at the product level but also at the process level.

The advantage of AS Group OCC line is ideal process, minimum energy consumption, and high quality machines

DIP LINE

AS Group Deinking cell consists of a number of cells in series with an elliptical cross-sectional with a baffle extending over the entire length to separate suspension chamber.

Flotation process is operated in a continuous mode and helps to remove ink particles efficiently.

Since the cells are interconnected by opening only, a level control system is required for the entire flotation machine

HEAD BOX

-The Headbox is an equipment that supply very low consistency stock into the forming section evenly. And uniformity of the final paper product depends on the dispersion of the fiber. The furnish delivery system varies on design of the headbox. It has a significant effect on paper qualities. All the headboxes are not suitable for all grades of paper and for machine speeds. A well-designed Headbox can provide board and paper with better quality and higher productivity. So the design should be optimal. Nowadays Hydraulic types of headbox are commonly used in the pulp and paper industry.

FORMING SECTION

The forming section type is usually based on the grade of paper or paperboard being produced. Older machines can be upgraded to include more appropriate forming sections.

PRESS SECTION

The second section of the paper machine is the press section, which removes much of the remaining water via a system of nips formed by rolls pressing against each other aided by press felts that support the sheet and absorb the pressed water.

DRYER SECTION

The dryer section of the paper machine, as its name suggests, dries the paper by way of a series of internally steam-heated cylinders that evaporate the moisture.

CALENDER SECTION

TA calender consists of two or more rolls, where pressure is applied to the passing paper. Calenders are used to make the paper surface extra smooth and glossy. It also gives it a more uniform thickness. The pressure applied to the web by the rollers determines the finish of the paper.

REEL SECTION

The paper is wound onto metal spools using a large cylinder called a reel drum. Constant nip pressure is maintained between the reel drum and the spool, allowing the resulting friction to spin the spool. Paper runs over the top of the reel drum and is wound onto the spool to create a master roll.

TECHNICAL FEATURES

Provide installation of polycarbonate/HDO lamella Sheet formation with optimization.

Edge flow control valves for optimization of fiber orientation profile.

Manually adjustable mechanical jacks for proper lip profiling control.

Tube bank with high open area.

SIZE PRESS SECTION

Size section additional sizing agents, including resins, glue, or starch, can be added to the web to alter its characteristics. Sizing improves the paper’s water resistance, decreases its ability to fuzz, reduces abrasiveness, and improves its printing properties and surface bond strength.

WINDER SECTION

Reels of paper wound up at the end of the drying process are the full trimmed width, minus shrinkage from drying, of the web leaving the wire. In the winder section reels of paper are slit into smaller rolls of a width and roll diameter range specified by a customer order.

Tp accomplish this the reel is placed on an unwind stand and the distances between the slitters (sharp cutting wheels), are adjusted to the specified widths for the orders. The winder is run until the desired roll diameter is reached and the rolls are labeled according to size and order before being sent to shipping or the warehouse. A reel usually has sufficient diameter to make two or more sets of rolls.
