Simplex Machine is used in the spinning mills. For Ring yarn Simplex machine is necessary. Simplex machine is the machine which converts the drawn sliver into roving form. Simplex process is the previous process of ring spinning process. A slight twist is given onto the roving. We can find different faults in the speed/roving/simplex frame. They[…]
Roller setting is a very important task in the spinning department. Incorrect settings lead to creation of various problems and hampers spinning conditions. The speed of the leading roller is always greater than the preceding roller. Incorrect setting leads to the variation of weight/unit lengths. If the setting between two pairs of drafting roller is[…]
Cone Drum As each layer of roving is added to the bobbin in the speed frame, its diameter is increased. In flyer leading and bobbin leading frame, it is necessary to increase or decrease the bobbin rpm respectively to maintain a constant surface speed on the bobbin surface as each layer is added to its diameter[…]
What are the Different Drafting Systems used in Speed Frame? The following drafting systems are used in speed frame: Description of Casablancas two-zone Drafting System The Casablancas two-zone drafting system is widely used for cotton on speed frame. The back zone draft takes the place between two pairs of roller, after which follows a zone with[…]
Objects of Speed Frame The purposes or objects of speed frame are: The package so produced is tapered or conical at each end and made sufficient firm so that it can be transferred without damage to the roving and yet will unwind readily at the next machine. Operations involved in Speed Frame The following operations are involved[…]
Fibres are spun into yarn, and yarns are woven or knitted into fabrics, and fabrics are then transformed into clothing products. There are three popular techniques of yarn manufacturing like ring spinning, rotor or open-end spinning and air-jet spinning. Among them, ring spinning is the oldest and till now used to make a wide range[…]
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[…]
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[…]
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[…]
The simplex or roving frame is a modern form of speed frame. It is also known as fly frame. It is capable of imparting higher draft to material (up to 25). One of the noticeable features of this m/c is to absence of sound & noise. The higher speed of this m/c (spindle speed about 1500 r.p.m)[…]
