Introduction :
Machine are subjected to deterioration due to their utilization together with exposure to surroundings condition. Process of deterioration if unchecked culminate inwards rendering these facilities unserviceable together with brings them to standstill. Industry thus has a selection but to attend to them from fourth dimension to time, to repair to keep together with to recondition them so every bit to elongate their life to the extent it is economically together with physically possible to orbit so. Thus repair, maintenance, accurate setting together with replacement of components assure importance every bit an technology scientific discipline function.

Overlock stitching machine

Objectives :

To know the repair physical care for of dissimilar components used inwards over border stitch machine.
To thin the way of maintenance of the machine for its longer life.
To know the dissimilar setting points of the over border stitch machine.
To get together cognition on how together with when the replacement needs to hold out carried out.
To bear ourselves alongside diverse mechanism tools.

Apparatus:

Flat screw driver.
Star screw driver
Hammer
Pliers.
Lubricating oil.
Grease.

Procedure
The Repair, maintenance, setting together with replacement physical care for are described below.

Repair :
Repair piece of work is carried out when a constituent requires slight modification. To ship out such chore the machine needs to hold out switched off first. The constituent nether repair is so screwed off yesteryear suitable apparatus. After repairing the component division is fixed to its designed house together with hence its correctness I measured yesteryear running the machine. In an over border stitch machine looper, presser foot, tensioner, depository fiscal establishment fit spring, motor belt etc tin undergo repair job.

Maintenance :
Maintenance tin hold out of dissimilar types. But next types are of import inwards this aspects

Routine maintenance : Lubrication together with regular inspection are the constituents of routine maintenance. Lubrication ensures long life together with prophylactic working of all the equipments. Inspection tries to notice faults inwards equipments so that repairs together with replacements may hold out undertaken at the right time.

Schedule maintenance: This type of maintenance provides for inspection, overhaul, lubrication together with servicing of the machine at predetermined dates. Overhauling of machine, cleaning of all components is commonly done on this machine. It involves opening of the machine into its smallest components together with ship out lubrication.

Setting:

The setting of the over border stitch machine is of immense importance. Folling setting points needs to hold out ensured earlier running the machine.

Needle: Needle undergoes accurate setting to ensure proper sewing. Needle is attached yesteryear agency of a screw which needs to hold out tightened plenty to create slow sewing. Again the needle size is also of import from textile betoken of view. In this machine , ane or 2 needle may hold out used together with it may hold out 3 thread , iv thread or five thread machine.

Stitch density controller: Its controls the no of stitches per inch. Before starting the machine, stitches per inch is determined yesteryear rotating the knob together with fixing it at the desired position.

Pressure foot: The type of pressure level pes to hold out used together with its proper stetting is important, which is ensured yesteryear proper attachment alongside the moor through machine pulley.

Tensioner : Proper stitching depends on appropriate tension on sewing thread. The tensioner is defective together with if it is non properly adapt so the stitch may hold out tight or unloosen or the sewing thread may hold out suspension down, so , tensioners are to hold out adjusted properly, inwards this machine 3 or to a greater extent than thread may hold out used . so her to a greater extent than tensioning device is used.

Motor: Motor rpm depicts the speed of the machine. The rpm is controlled yesteryear tightening or loosing the belt over machine together with motor pulley.

Replacement :
the replacement is revealed when the relation of equipment is no to a greater extent than remains an economical proposition. Influenza A virus subtype H5N1 replacement is affected when the equipment is subjected to consummate breakage which tin non used fifty-fifty afterward repair or the components has move so obsolete that affects production or it has crossed its croak date.

Conclusion :
Over lock stitching machine is necessary for stitching garments fabric. By doing this experiment, nosotros tin know most the diverse parts of the machine together with its parts setting together with its working procedure. We tin larn its repairing physical care for also. So nosotros create got learned most this machine mechanism properly together with keep proper lubrication for shine operation.
