  Process

The two main processes in “Hand made paper” manufacturing are :
Preparation of pulp and the lifting of paper. Preparation of pulp is done by Hollander type Beater directly for the raw material other than the Agro-waste. For the Paper to be made from Agro-waste fiber, the raw material is first digested in suitable Digesters & then useful digested material is converted into pulp by Hollander type Beater. Pulp should be free from knots & lumps.

Raw material:
“Hand made Paper” Industry uses different types of raw materials like new & old cotton Rags, Hosiery & Tailor cuttings, jute waste, paper waste & Agro-waste fibers like Bagasse, Banana, Mulberry, Hemp & Remi etc. Many more different grades of “Hand Made Paper” can be manufactured from these Raw materials.

Now following different processes are outlined apart from beating raw material to convert the same in pulp.

Rags/ Tailor cuttings sorting:
Rags/ Tailor cuttings are sorted carefully & thoroughly screened and dusted before Beating to remove the non cotton fibers like metallic pieces, Buttons & elastics etc.
Rags cutting:
The sorted rags then well cut into small pieces to the size of 1inch to 1.5 inch by means of Rag chopper machine.
Beating (Pulping):
In Hollander type Beater machine the sorted Rags or digested Agro-waste are beaten to knot free & lump free pulp or described above.Different mild chemicals such as Rosin (Abetic Acid), Alum, Dicol, colouring Azo group free dyes etc. are added for getting different quality of papers to be lifted on Vats.
Paper lifting:
Paper is prepared with the help of vat machine – The water content of pulp gets drained from wire mesh & sheet of desired weight (GSM) is formed on the surface of wire mesh of mould of vat machine.
Couching:
The wet sheet is transferred to woolen or cotton felt of different surface finishes spread on couching table. By applying pressure by hand on wire mesh of mould paper sheet is transferred to felt. Pile of sheet is formed thereby. Hence same mould is used again & again for lifting other paper Sheets.
Pressing:
The pile of wet sheets & felts together are pressed in screw press or hydraulic press to remove excess water from the pile of paper sheets & felts to maximum.
Separation:
The pressed sheets of paper are then separated manually from felts & the same felts can be reused again.
Drying:
Separated pressed sheets of paper are then dried under the shed by clamping or on wooden stands like clothes. Fans, Heaters may be used in closed sheds for quick drying of paper sheets.
Sorting & cleaning:
The dried paper sheets with & without defects are separated carefully & then are cleaned by means of wire brush and sharp blades etc.
Glue sizing / Tub sizing:
The defectless sheets of paper as per requirement or demand are then dipped in Animal glue solution to make paper sheet more durable for painting & writing. This is also called external sizing.
Calendering:
In this machine sheets of paper are sandwiched in between galvanized iron sheets or zinc metal sheets by passing through heavy rollers to impart desired finish such as: Rough, Medium, Smooth Burlap, Mat etc.
Cutting:
The calendered sheets are then cut in to desired sizes using Guillotine cutting Machine.
Packing:
Cut paper sheets are counted & packed properly in suitable quantity and labeled accordingly to make them ready for sale in the market.
