The beltdrive  is a mmpratively simpler device than gearing for transmission of power and for increasing or decreasing the speed of motion. Beltdrive came to India m  the fonn of  the spinning wheel. The spinning wheel quickened  the speed of  spinning by about six fold. This must have multed in reducing the prices of  yarn and, thus, of  cloth. The other improvement in the spinning wheel was the addition  of  crank handle 6uring the seventeenth century. The beltdrive was  extended  to the diamond cutting drill, by  the seventeenth century. Weaving Evidence of an improvement in weaving comes from a fifteenth century dictionary which describes  the foot-pedals used by a weaver to control speed. The addition of treadles to the loom facilitated  the use of feet by  the weaver for lifting alternately the heddles and freed hi3 hands to throw the shuttle to and fro (Fig.). This could more than double the rate of weaving.  


By  the seventeenth century both methods of multicolour pattern dyeing, namely, the use of resist to confine colours to patterns and of mordant to take colours were used.  It was, perhaps, during the same century that direct block printing, a time-saving  technique as compared to painting, became popular in  India.
