# Gearing Calculation of Apron Draft Jute Spinning with Easy 2 Formula

Sharing is caring!

## Introduction:

In order to control the original drafting of a sliver, the apron draft spinning frame is very well suited to do so, as it is drafted by a few rollers as well as aprons. It is therefore called Apron Draft Spinning Frame. This spinning frame produces much more yarn than the conventional spinning frame does, and the yarn is much more balanced. The yarn is extremely strong and is much stronger than the conventional spinning frame. In this article, we will learn gearing calculation of apron draft jute spinning frame with easy formula.

## General Specification of Apron Draft Jute Spinning:

• Motor rpm                               = 1250.
• Motor pulley diameter             = 8.5″
• Machine pulley diameter          = 13.5″
• Tin cylinder diameter              = 5.8″
• Flyer diameter                         = 1.8″
• TCP                                            = 37T
• DCP                                           = 49T
• Drawing roller diameter         = 2.4″
• Retaining roller diameter       = 1.3″

## Formula Require for Gearing Calculation:

Following 2 formula is require for gearing calculation of apron draft jute spinning frame.

## Result of Calculation of Apron Draft Jute Spinning:

1. Flyer speed= 2536 RPM
2. Surface speed of retaining roller= 40.98 inch/min.
3. Surface speed of drawing roller= 940 inch/min.
4. Surface speed of tin cylinder= 14,333.52 inch/min
5. Draft=23
6. Draft constant= 1127
7. Twist/min= 3
8. Twist constant= 111

## Conclusion:

An apron drafting sliver spinning frame is a very important and necessary machine in any jute industry. In this article, I tried my best to present the calculation in a simple way.
