PROSINO S.r.l., a market leader in the manufacturing and marketing of spinning and twisting rings since 1946 will introduce a new “Long Staple Spinning Manual” at the next ITMA show in Milan. ITMA will be held from 12th to 19th November 2015 and Prosino hopes that the tips and suggestions in its Long Staple Spinning Manual will help customer increase productivity and yarn quality.


Driven by the strong demand from fine count worsted customers, PROSINO has found that the adoption of conical rings “4+4” with h 9,1 mm is helping to increase spindle speed by up to 8% over the more conventional h 11,1 mm.


The reason for this achievement is that if we reduce the height of the ring from 11,1 mm to 9,1 mm, we can distribute the same load over an area that is approximately 20% larger.


The term “specific pressure” defines the load/resting surface ratio. This greater area of contact (at the same rpm), decreases the specific pressure, thereby allowing the spinning machine to increase the spindle rpm.


PROSINO manufacturers h 9.1 conical rings in its plant in Italy, for any type of spinning machine on the market. It offers these in diameters of 42 x 9.1, 45 x 9.1, 48 x 9.1, 51 x 9.1,

52 x 9.1


PROSINO will demonstrate to the ITMA international audience the practical results for the application of these rings.
