Sliver and Roving Length Measuring Machine

DESCRIPTION / TECHNICAL SPECIFICATIONS

This is a Sliver and Roving Length Measurement Machine, a fundamental sample preparation tool designed to wind a precisely predetermined length of sliver or roving with high accuracy. This instrument is the crucial first step in the process of determining linear density (count) and fully complies with the methods in international standards such as ISO 2060 and GB/T 4743. The following are its detailed technical specifications.

At the core of this machine is a roller drum engineered with high precision to have a standard circumference of 1000mm (1 meter) with a tolerance of only ±1mm. This strict circumference precision is essential to ensure the accuracy of the reeled sample length (known as a skein), which is the basis for a valid yarn count calculation. A 36-inch circumference option is also available for laboratories that use the imperial measurement system.

Designed for functionality and efficiency in the laboratory, this machine features a 250mm wide roller that can accommodate various types and thicknesses of sliver or roving. The instrument is suitable for a wide range of natural and synthetic fibers, including cotton, wool, and silk. The package includes a creel stand that can hold up to two roving bobbins simultaneously, allowing for faster sample preparation or comparisons between bobbins.

As an essential sample preparation tool, this machine plays a vital role in the quality control workflow of a spinning mill. By producing skeins of sliver or roving of a precisely known length, these samples can then be weighed on a precision balance to calculate their linear density (e.g., in Tex or ktex). This process allows mills to continuously monitor and control the consistency of their production from the earliest stages, ensuring the final yarn quality meets the desired specifications.
