Name of the Experiment: Study on Bar tack sewing machine & produce sample

Introduction:

There are many types of sewing machine Some are used for special purposes such as bar-tack, button hole attaching machine, button hole making machine etc This type of machines works in a cycle and so these are called simple automatic machine Here we study on a type of machine that is bar tack machine Bar tack means to increase strength of small length of fabric by sewing on it and then

by repeating it For example – belt loop, opening of pocket

It is a simple automatic machine which produces stitches in

a cyclic order

Objectives:

1 To know about the machine parts

2 To know about the thread path

3 To know about the parts of bar tack machine

Description:

In a few length of cloth sewing again and again after sewing one time to increase the power of bearing load of that place of cloth is called bar tack A bar tack machine can sew strongly with in a few lengths cyclically At first doing tak stitch (1-2 cm) then in opposite make cover stitch (zigzag) on tak stitch A little change can be done between

Working principle:

At first this machine produces tack stitches in a small length (1-2 cm) and then sews covering stitches over and at right angles to the first stitches The variables are the number of tacking stitches and the number of covering stitches Typical uses are closing the ends of buttonholes, reinforcing the ends of pocket openings and the bottoms of flies and sewing on belt loops The adjustment points of this machine are needle, pressure feed, stitch length, stitch density

Uses of Bar Tack Sewing Machine:

2 Increasing strength in corner of pocket

3 Closing the two corners of button hole

5 In that place where more strength is needed to support

Conclusion:

This type of machine can not be used for normal purpose But for making a complete garment their importance can not be denied Special care and sufficient knowledge is necessary for proper working Otherwise faulty sewing may

be done I would like to give special thanks to our teacher I

am also grateful to our instructors I think this will be very helpful in my future life

equipment it is used on Bar tacking is commonly used on backpacks, tents, tactical gear, and other heavy wear sewn items where normally sewn stitches might give way at a crucial moment In general, bar tacking is a sign of good quality, although the rest of the product should always be looked over carefully as well When a sewing pattern calls

for bar tacking, it indicates that the designer feels that section of the pattern is a critical area that needs extra reinforcement

Bar tacking is accomplished by sewing a very tight zigzag stitch across the width of the material In some cases, the manufacturer may go over the bar tacking again, causing the stitch to have an x-like form Usually, very strong threads are chosen for bar tacking so that they will stand up

to high pressure When done correctly, bar tacking can help support loads of up to 400 pounds (almost 200 kilograms) Many backpacking companies in particular pride

themselves on the number of bar tacks integrated into their products, claiming that they will wear harder and longer than the competition

For commercial work, specialized bar tacking sewing machines are capable of handling high volumes of bar tacking through heavy materials like nylon webbing and canvas Commercial bar tacking machines tend to be expensive, however, and smaller companies prefer to modify their existing sewing equipment Home sewers can bar tack if they have a zigzag setting on their sewing machines, although they may have to do it by hand if the material is very thick In both cases, a heavy weight waxed thread should be used

Bar tacking works to reinforce material by spreading pressure more evenly along the width of the fabric, with a large number of stitches covering a small area When pressure is put on the bar tacked area, the thread will not give way as readily, because it is not in a straight line in grain with the fabric, as most sewing is Indeed, fabric will

more frequently give way around bar tacking, especially if

it is old, or if it has been stressed by the elements

Bar tacking can be seen reinforcing rock climbing

harnesses, hang gliding gear, and a wide variety of other

products manufactured for outdoor sports Because much of

the gear bar tacking is used on is critical to survival, it is

important to frequently inspect and test such gear and to

discard equipment that seems unreliable In general, if

support gear is frayed or worn, stretched out of shape, or

torn, it is probably not safe for use
