Repair, Maintenance, Setting and Replacement of Different Parts of Overlock Sewing Machine
Introduction :
Machine are subjected to deterioration due to their use and exposure to environment condition. Process of deterioration if unchecked culminate in rendering these facilities unserviceable and brings them to standstill. Industry therefore has a choice but to attend to them from time to time, to repair to maintain and to recondition them so as to elongate their life to the extent it is economically and physically possible to do so. Thus repair, maintenance, accurate setting and replacement of components assure importance as an engineering function.

| Overlock stitching machine |
- To know the repair procedure of different components used in over edge stitch machine.
- To lean the way of maintenance of the machine for its longer life.
- To know the different setting points of the over edge stitch machine.
- To gather knowledge on how and when the replacement needs to be carried out.
- To acquit ourselves with various machinery tools.
- Flat screw driver.
- Star screw driver
- Hammer
- Pliers.
- Lubricating oil.
- Grease.
The Repair, maintenance, setting and replacement procedure are described below.
Repair :
Repair work is carried out when a component requires slight modification. To carry out such job the machine needs to be switched off first. The component under repair is then screwed off by suitable apparatus. After repairing the part is fixed to its designed place and hence its correctness I measured by running the machine. In an over edge stitch machine looper, presser foot, tensioner, check spring, motor belt etc can undergo repair job.
Maintenance :
Maintenance can be of different types. But following types are important in this aspects
- Routine maintenance : Lubrication and regular inspection are the constituents of routine maintenance. Lubrication ensures long life and safe working of all the equipments. Inspection tries to detect faults in equipments so that repairs and replacements may be undertaken at the right time.
- Schedule maintenance: This type of maintenance provides for inspection, overhaul, lubrication and servicing of the machine at predetermined dates. Overhauling of machine, cleaning of all components is normally done on this machine. It involves opening of the machine into its smallest components and carry out lubrication.
The setting of the over edge stitch machine is of immense importance. Folling setting points needs to be ensured before running the machine.
the replacement is revealed when the relation of equipment is no more remains an economical proposition. A replacement is affected when the equipment is subjected to complete breakage which can not used even after repair or the components has become so obsolete that affects production or it has crossed its expiry date.
Conclusion :
Over lock stitching machine is necessary for stitching garments fabric. By doing this experiment, we can know about the various parts of the machine and its parts setting and its working procedure. We can learn its repairing procedure also. So we have learned about this machine mechanism properly and maintain proper lubrication for smooth operation.
- Needle: Needle undergoes accurate setting to ensure proper sewing. Needle is attached by means of a screw which needs to be tightened enough to produce easy sewing. Again the needle size is also important from fabric point of view. In this machine , one or two needle may be used and it may be 3 thread , 4 thread or 5 thread machine.
- Stitch density controller: Its controls the no of stitches per inch. Before starting the machine, stitches per inch is determined by rotating the knob and fixing it at the desired position.
- Pressure foot: The type of pressure foot to be used and its proper stetting is important, which is ensured by proper attachment with the moor through machine pulley.
- Tensioner : Proper stitching depends on appropriate tension on sewing thread. The tensioner is defective and if it is not properly adjust then the stitch may be tight or loose or the sewing thread may be break down, so , tensioners are to be adjusted properly, in this machine three or more thread may be used . so her more tensioning device is used.
- Motor: Motor rpm depicts the speed of the machine. The rpm is controlled by tightening or loosing the belt over machine and motor pulley.
the replacement is revealed when the relation of equipment is no more remains an economical proposition. A replacement is affected when the equipment is subjected to complete breakage which can not used even after repair or the components has become so obsolete that affects production or it has crossed its expiry date.
Conclusion :
Over lock stitching machine is necessary for stitching garments fabric. By doing this experiment, we can know about the various parts of the machine and its parts setting and its working procedure. We can learn its repairing procedure also. So we have learned about this machine mechanism properly and maintain proper lubrication for smooth operation.
