Abstract

PURPOSE: To reduce the working hours and to obtain coils with uniform shape, by correcting the shape of the diamond coil end through the use of a bending and forming machine with the expanding force of the straight portion of the coil being utilized.
CONSTITUTION: At the location adjacent to the outside of the straight portion 2 of the diamond coil end 4, an end-shape correcting lever 11 is provided rotatably about a pin 12, and the laver 11 is always kept in a predetermined position by a spring 13. At the location adjacent to inside of the coil head portion 3 of each coil end 4 of the bottom coil and the top coil on the wooden end pattern 8, a bottom coil head stopper 14 and a top coil head stopper 15 are fixed. Thus, an arm 7 of a bending machine can correct the shape of the coil end 4 in a short time by utilizing the expanding force of the straight portion 2 of the coil, said force having the direction shown by an arrow, and coils with uniform shape can be obtained.
