ABSTRACT:
A method and an apparatus for changing the sewing direction of a multiple needle flat sewing machine for sewing elbow pads of sports wear, jumpers, etc. and patchworks of various shapes. Needles are stopped at the needle upper dead center position; a throat plate is moved in a direction contrary to the sewing direction; a needle thread or looper thread caught on tongues of the throat plate is released from the tongues; and the sewing direction can be changed at any desired angle in relation to the sewing direction at the start, such as a right angle, an acute angle or an obtuse angle. The present invention also makes it possible to carry out fancy stitching with thick thread by a multiple needle flat sewing machine.
