description

The mule spinning frame guarantees the production of high-quality woollen yarns.

Main advantages of the mule spinning frame:

1) continuous draft on a 3 to 6 m- field, well above the ring spinning system. Recent laboratory tests confirmed that draft is more natural (no fibre or yarn stress) and homogenous, because the tensile force is spread across a much wider path length

2) Continuous yarn twist (without the false twist of the ring spinning system)

The yarn is constantly twisted before and after being spooled, thus preventing the uneven fibre relief on the winding axis and keeping the Uster uniformity index extremely high. The risk of ends breakage during the drafting operation is reduced when short and/or fine fibres are present, such as cashmere and angora or fibres of different type, fineness and length.

details

tension control system

The accurate tension control system of the spooling and yarn tension fallers guarantees a perfect cop formation.

control system

A computerised system controls all the machine functions, including the carriages movement, the feed carriage speed, the adjustment of yarn feed speed and drafting percentages, the reverse speed, the spooling speed and the cops formation.

available versions

mule spinning frame mod. C7

Mule spinning frame equipped with movable feed carriage and stationary spindle carriage. This machine is the perfect solution when high quality, in terms of fine and extra-fine fibre count (yarns count up to Nm 60), and yarn uniformity are required. It is mainly used in plants producing cashmere yarns or other high quality fibres, where the yarn high quality is more important than high production capacity.

mule spinning frame mod. C4

Mule spinning frame with simultaneous movement of the feeding and spindle carriages. The total path length is evenly split between the movements of the spindle and the feed carriages. This solution requires half the time to complete the cariages movement, thus increasing the overall efficiency of the spinning unit by 30% (model C4-40) compared to the traditional machines. Draft percentages of 50-55% can be reached thanks to the splitting of drafting field in two sections. Hence the possibility to condense a coarser yarn count on the tape condenser of the carding set, to the benefit of yarn uniformity and plant production capacity.
