Abstract:

A flatlock seam is the most frequently used type of seam found in clothing, and comprises the two edges of the fabric being pressed open and flat before being joined.this seam is stitched with the help of flatlock machine. We have discussed Its parts and mechanism.

Theory:

Oiling mechanism:

Oil is essential for the machine. To keep the machine parts oily at every time, it has to make oil path well organized. Sewing machine has oil pump assembly at lower portion of the machine. Pump sucks the oil in the tub of the machine and pumps it to all parts of the machine.Pump has two functions. First it provides oil to all parts and secondly, extra oil is sucked by it to circulate the oil all the time in machine parts. It has two main pipes. One pipe is called hook oil pipe and it oil the hook driving shaft. Other pipe is called main shaft oil tube. It oils the main shaft and needle bar. Oil which comes out of the needle bar is accumulated in return pipe assembly. Oil pump assembly sucks that oil through return pipe assembly. In this way oil circulates in machine parts.

Apparatus:

Screw drivers, flatlock machine.

W600 flatlock machine oil mechanism:

An oil pump for a sewing machine, comprising:

Housing:

An adjustable gear hub assembly on an interior of said housing for driving at least one gear pump, said gear hub assembly being adjustable for a tight fit within said housing; and at least one coverplate having an interior face contiguous with an exterior surface of said housing, said interior face having a column extending vertical upward, an uppermost segment of said column connecting with a bypass channel extending diagonally downward, for removing excess oil from said oil pump, while leaving a supply of oil in said oil pump.

A sewing machine comprising:

An oil pump assembly having at least one coverplate with one face having a column therein extending vertically upward connecting with a bypass channel extending diagonally downward from the connection of said column to said channel; means for removing excess oil from said oil pump assembly; and means for leaving a supply of oil in said oil pump assembly for use as a lubricant upon start-up of said sewing machine.

An oil pump assembly comprising:

Housing:At least one coverplate adjacent to said housing having an interior face contiguous with said housing, said interior face having a column extending vertically upward to

connect with a bypass channel extending diagonally downward from the connection of said column to said channel for the removal of excess oil from said oil pump assembly, while leaving a supply of oil in said oil pump assembly for use as a lubricant upon start-up of said sewing machine.

Conclusion:

These parts and there arrangement must be known for machine maintainance and

for improvement of production efficiency.
