Hence more downtimes for the machine. Result of a somewhat larger cradle aperture «X»: Uster values on the roving frame are 0.2 – 0.4% worse but good working behaviour on the roving frame good working behaviour on the ring-spinning machine. – up to 30% fewer end-breaks. – no measurable difference in the Uster
ROVING FRAME. Roving machine is complicated, liable to faults, causes defects, adds to production costs and delivers a product that is sensitive in both winding and unwinding. This machine is forced to use by the spinner for the following two reasons. 1. Sliver is thick, untwisted strand that tends to be hairy and to create fly
22 Feb 2015 Speed Frame and function of speed frame .The output from the draw frame is fed into the roving frame (also called 'speed frame or Speed Frame and it's Function :simplex machine or flyer frame') where the linear density of sliver is reduced by drafting and the resultant product is called the roving.
ROVING FRAME Roving machine is complicated, liable to faults, causes defects, adds to production costs and delivers a product that is sensitive in both winding and unwinding.

The third task cannot be directly attributed to spinning: it lies in winding the roving into a package that can be transported, stored and donned on the ring spinning machine. It is the winding operation above all that makes the roving frame a relatively complex and problem-plagued machine. This winding operation requires,
required will be less and the cost per machine is also high. The following table can be a guide line for speed frame delivery hank. ?. 2. 12. With 4 over 4 drafting system, the total draft can be up to 13, whereas in 3 over 3 drafting systems , the draft can not be more than 11. The Roving thickness and Roving hairiness(yarn

Roving. FAQ's. 1. What is the need for roving frame in the ring spinning system? Ans: In ring spinning system, conversion of sliver into yarn through a single step has not one spinning position of ring spinning frame, so there is need to have finer What are the functions of the builder motion in a roving machine? Ans:.
