    Basic Information

Technology developed: Mechanized Roller for Felt Making (TP19768630862)
Category: Product (Hardware/Material/Software)
Details of Inventor(s):
Inventor Institution/Organization/Company Department Designation
Dr. R. P. Saini Indian Institute of Technology Roorkee Department of Hydro and Renewable Energy Professor
Technical Application Area: Engineering
If 'Other', please specify:
Please give more details of new technical application area:
The modification in the mechanized roller with different sizes are made on the basis of ornamental handcrafted felt. The basic rolling structure has one roller made of pipe which is supported at both the ends by bearing brackets pinned at the end of equal size light beams. The pipe has a straight slot across the length for anchoring jute cloth on which woolen bats are laid. Two wheels with a rotating shaft supported by bearings are located at the other end of beams which enable easy motion to the device when pulled and pushed. The beam ends are provided with jack for lifting rolling pipe which helps in the unwinding of rolled mat. U shaped pipe is hinged on both the beams for pushing the device. There is an option for using larger diameter roller instead of pair of wheels for energizing a small beater or weight drop on wool and also for adding rolling support to the main rolling pipe. Plastic bubble sheets are laid over the woolen bats before rolling. It holds fibre at bubble points whereas the spaces around the bubbles help in movement of woolen fiber during felting. The Technical specifications of roller in given as Roller 1-2.5 feet, size-2x6 feet to 2 x 8 feet Roller 2-4.0 feet, size-3 x 6 feet to 3 x 8 feet Roller 3-5.0 feet, size-4 x 6 feet to 4 x 8 feet

Please describe in detail including the TRL Level:
To assess the performance of the developed roller the testing of the rollor was carried out in association with skilled craftsmen of Kashmir in the laboratory for the artisans of Himachal Pradesh and Gujarat. In order to examine the quality of felt prepared by rolling device, felt samples were tested in the laboratory at Northern India Textile Research Association Ghaziabad. Quality of Namda was measured on the basis of different parameters such as mass thickness tensile strength and thermal resistance. Based on the results and queries raised by the operators different sizes of rollers were developed. 2 unit of felt rollers have been demonstrated in the field for group of Namda makers.


Applications: Ornamental felt Prayer mats Yoga mats Floor covering material and Insulation purpose
Advantages: Discarded wool can be utilized for making non woven woolen fabric through this technology. Women participation in the production of felt. This being a women friendly technology. Easy to roll felt and far less strenuous operations. There is a substantial reduction in physical labour. Can be operated by women and unskilled labour while the traditional rolling requires highly skilled craftsman. Limited shrinkage in felt size while rolling. Layered wool remains in place and there is no distortion of embedded designs. It is based on pushing and pulling by hand instead of kicking and pushing by legs. There is a substantial reduction in physical labour. It can be transported easily and does not require major modification of the existing floor used for felt making. Winding and tying of mat for rolling felt is much easier and faster as compared to the traditional method. There is saving in rolling time while felting in bulk or large sized pieces. The cost of equipment is about 5 to 20 thousand depending upon the size of the felt. It allows the production of 6 to 7 excellent quality felt sheets per day of different sizes by a skilled craftsman as compared to 3 to 4 by the conventional method.

I-Mitra(आई-मित्र) Welcomes You..
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
