The factors which put limitation for higher production in ring frame are – Maximum traveller speed It is limited by the types of ring flange, style of traveller, wt. of traveller and rate of traveller run. Maximum roller delivery speed The limiting factors beings the ability of the operative to piece-up the broken ends and the […]
What are the Functions of Ring, Traveller, Creel, Spindle, Roving Guide and Lappet Motion?
Ring The functions of ring are: Traveller It performs the following functions: It also performs many other functions involving highly complicated problems of higher physics. Creel The function of the creel is to hold the roving bobbin over a roller beam within a convenient height to easily handle the roving. The creel must permit […]
Classification of Drafting System in the Ring Frame | Explanation of a Modern System
Drafting system can be broadly classified under two heads namely: The system with apron can again be classified into three groups: Example of regular drafting system without apron: Example of single apron drafting system: Example of double apron drafting system: Example of multiple Apron drafting system: OM – Super High Draft System This system is […]
Causes of Faults Found in Ring Frame Yarn
The Faults Found in Ring Frame Yarn and their Causes Soft Yarn Generally caused by slack spindle bundles, twist change wheel too large, empty bobbins not properly pushed down during doffing. Uneven Yarn Either travelers are too heavy or for spinning fine counts from inferior cotton. Fuzzy Yarn Rings too large, by ballooning or bad lubrication of […]

Ballooning Effect in Ring Frame
During spinning operation the drafted strand of fibre being delivered and held at one end by the front rollers, the other end rotates round the bobbin with the traveller on the ring. It is observed that the thread between the thread guide and the traveller, is bulged out which is called the ballooning effect if the thread; and the […]
Types and Functions of Ring Traveler | Factors Considered for Selecting a Ring Traveler
Types of Traveler Among the types, round and C travelers are mostly used for spinning finer count as they give less friction. Flat and semi-circular travelers are used for coarser yarn. Functions of Traveler Traveler no. or Traveler Size Traveler no. expresses the wt. of traveler. It can be done in two ways – Indirect System […]
What is Ring Spindle? | Essential Qualities of a Spindle | Inverter Drive for Spindle
Definition of Ring Spindle Spindle is the heart of ring frame. A spindle is regarded as a production unit of a spinning mill. The capacity of a spinning mill is expressed by the number of spindles in the mill. On an average the spinning mill of Bangladesh have 25,000 spindles. This may be up to 1, […]
Ring Spinning: Definition, Objects and Main Operations
Ring Spinning The ring spinning is the most widely used form of spinning machines due to significant advantages in comparison with the new spinning process. Ring spinning is a method of spinning fibres, such as cotton, flax or wool, to make a yarn. In ring spinning, the roving is the first attenuated by using drawing rollers, then spun and wound around […]
