1.The driving gear w attached to the Y-pulse motor q oscillates the idle gear e.

2.When the idle gear e oscillates, the Y-timing belt y moves forward and backward through timing pulley (A)t attached to Y-pulley shaft (A)r.

3.The belt holder u and the Y-driving shaft holder i which are fixed to the Y-timing belt y operate the Y-driving shaft o.

4.The X-feed shaft support !0and the X-feed shaft !1are attached to the Y-driving shaft o. The presser arm assembly !2 is attached to the Y-feed bracket !3.

5.The Y-feed bracket !3operates in the Y-direction (moves longitudinally) via the Cross roller !4and the Y-feed guide !5.

1.When the Y-pulse motor q operates, its motion is transmitted to the driving gear r attached to the Y-driving gear shaft e via the coupling w.

2.The driving gear r is engaged with the rack of the Y-driving shaft t, and the Y-driving shaft t moves back and forth.

3.The work clamp arm assy i is attached to the Y-feed bracket o via X-feed shaft support 326 y attached to the Y- driving shaft t and the X-feed shaft u.

4.The Y-feed bracket o operates in the Y-direction (back and forth) via cross roller 326 !0and Y-feed guide 326Y !1.
