Q.1- What is the other name of Roving in cotton spinning?
C.1. Roving in cotton spinning is also called flayer.
Q.2-What is the Flayer Machine?
C.2. Since it is not possible to feed the yarn machine as a band from the draw frame (except for the OE spinning system), the bands need to be thinned a little more. The machines that bring the bands into a form that can be processed on the spinning machine are called flayer machines.
Q.3-Which machine is the Roving Ribbon obtained from?
C.3. Since it is not possible to feed the yarn machine as a band from the draw frame (except for the OE spinning system), the bands need to be thinned a little more. The product obtained from the flayer machine, which brings the bands to a form that can be processed in the spinning machine, is called roving strip.
Q.4- What are the functions of the Flayer Machine?
C.4. a) Thinning the drawstring band and turning it into a roving with the drawing process
b ) Reinforcing the roving with twisting
c) Wrapping the roving in bobbins and bringing it into a form suitable for spinning on the ring spinning machine
S.5-Flayer machine winding part;
a) What is the function of the car?
b ) What is the function of spindles?
c) What is the function of the butterfly?
d ) What is the function of the Pressure Finger ( Claw ) ?
C.5. a) It is the part that carries the spindles and the butterfly on it. It moves up and down. In order to make a complete coil winding and to ensure the conicality in the coil, the stroke movement of the car decreases a little at each revolution. Along with the course length, the car speed should decrease in the same proportion. These operations are provided by the switch (lock) device.
b ) Working with the butterfly, it wraps the wicks on the wick pen.
c) It is the element that gives the wick to the wick pen properly.
d ) Winding is done properly with the guide part at the appropriate tension.
Q.6- What is the other name of Roving in WOOL spinning?
C.6. In wool spinning, roving is also called finisher.
Q.7- WHAT IS THE PURPOSE OF FINISHING?
C.7. Since the feeding machine cannot be fed to the yarn machine as a tape from the drawing machines, the tapes should be thinned a little more. The machines that bring the bands into a form that can be processed in the spinning machine are called roving (finisor) machines, and the obtained one is called roving tape. The main difference of these machines is that Butterfly twisting is used to give strength to the roving in the flayer machine, while the rubbing Technique is used to give strength in the finisher machine. In the flayer, a wick is wound into a pen. In the finisher machine, two rovings are wound into a pen. In worsted and semi-worsted wool spinning, there is a roving process before spinning. In Strayhgarn spinning, there is no roving machine and roving is obtained at the exit of the carding machine.
Q.8- What is the roving (finer) machine?
C.8. Since it is not possible to feed the yarn machine as a band from the drawing machines, the bands need to be thinned a little more. These are the machines that pull the bands into a form that can be processed in the spinning machine.
Q.9- Which technique is used to give strength to the roving in the flayer machine?
C.9. Butterfly twisting techniques are used.
Q.10- Which technique is used to give strength in the finisher machine?
C.10.rubbing technique is used.
