WHAT IS A SELF ACTING MULE? AND A RING SPINNING MULE?
The spinning mule was invented in 1779 by Samuel Compton after the invention of the spinning jenny and the water frame. The spinning mule was used to spin different types of fibers. The way it works is the following: a sliver or a roving of wool (in Hilaturas Jesús Rios case) passes between a set of rollers. The roller draws a part the wool fibers achieving a finer and smoother sliver. The roving then spurns on bare spindles which are mounted on a moving carriage. The moving spindles draw and spin the yarn but still without any tension and therefore achieving a strong yarn that can be spurned without being broken in the process.
In 1834 Richard Roberts added a camshaft, quadrant and winding chain to the regular mule in order to produce a self-acting mule. The self acting mule was considered a huge invention because human assistance was not required and therefore became the most important machine in the textile industry in the nineteenth century. The self – acting mule could spin all type of yarns; very fine yarns as well as very coarse yarns.
HILATURAS JESÚS RUBIO still nowadays works with self-acting mules which means that still works in a traditional way producing an accurate and resistant yarn but also HILATURAS JESÚS RUBIO is adapted to modern times by using ring spinning mules. Ring spinning mules replaced the self acting machines; because a ring spinning mule requires smaller space and more yarn quantity is obtained.
The Ring Spinning mule increases productivity and therefore reduces production costs.
HILATURAS JESÚS RUBIO adapts to customers requirements: ring spinning mule or self acting machine can be used in our spinning mill
