winding machines are used for wrapping threads

Winding machines are used for wrapping threads, yarns, wires, ribbons, taps, ropes,

twines, strings, or cords onto a bobbin, spool, or reel. These machines are used in textile

manufacturing processes – in weaving, where the yarn is wound onto a bobbin, and then

used in a shuttle.

Winding machines are used for wrapping threads, yarns, wires, ribbons, taps, ropes, twines,

strings, or cords onto a bobbin, spool, or reel. These machines are used in textile manufacturing

processes – in weaving, where the yarn is wound onto a bobbin, and then used in a shuttle.

Winding machines have a center roll on which the material is wound up. Generally, there

are metal bars that travel through the center of the roll, and are shaped as required for the

intended purpose. For example, a square bar provides greater potential for torque; while a

circular bar smoothest the process with greater speed. Edge sensors, which are mounted

on adjustable slides to accommodate different widths, are used to perceive how empty or

full the center roll is, as the width increases as the center roll is filled. The sensitivity of this

sensor is dependent upon the required speed of the operation.

There are a number of different types of winding machines used to wind various kinds of

materials, and used for different purposes; the major types used being –

coil winding machines rope winding machines spool

Coil winding machines

Rope winding machines

Spool winding machines

Cop winding machines

Pirn winding machines

Paper winding machines

Film winding machines

Foil winding machines

In this blog, we will discuss about cop winding and pirn winding machines, and how they

both differ.

Cop winding machines

Cop winding machines are generally used in the textile industry to wind jute and supply the

weft yarn. The machine has four heads, which helps it to wind four cops at the same time. It

also has clamps that help the machine to control the length of the yarn. Moreover, the

shape and size of the cop can be easily adjusted. Tube or bobbins are not used here to form

cops, but necessary amount of pressure is needed for the same. Two notable features of cop

winding machines are that these machines are completely in auto-stop motion system; and

that the output winding package is smaller than the supply package.

Pirn winding machines

Pirn winding machines are available in two types – automatic pirn machines, and ordinary

pirn machines. Both these machines are suitable for winding cotton, nylon, silk, wool, and

synthetic polyethylene fiber yarns. A pirn winding machine generally consists of four

spindles. Two such machines can be joined together to obtain eight spindles, where each

unit of 4 spindles and 8 spindles can be driven individually.

How are cop winding and pirn winding machines different?

As mentioned above, the weft package in cop winding machines are of jute, while

that of pirn winding machines is cotton.

Another clearly explained feature above is that cop winding machines facilitate the

winding of only four cops at a time, while pirn winding machines can wind more

than four pirns at a single given time.

Pirn winding machines use bobbins, while cop winding machines don’t require any

bobbin usage.

In cop winding machines, each of the four cops can be wound by a separate motor,

meaning the availability of four different motors; while in pirn winding machines,

only one motor is used for a single machine.

In cop winding machines, the cop creates pressure n the winding package, while

there is no pressure on the winding package in pirn winding machines.

whatever your requirement you can get the best

Whatever your requirement, you can get the best quality cops and pirns for a range of

different machines, and single/multi use, at Trim Engineering Services, one of the most

reliable cops and pirn manufacturers in India .
