此外，机头2a及2b、折边装置4、收料装置均通过电机或气缸驱动自动运行，实现自动贴袋。
所述的双机头贴袋机的工作过程大体如下：
口袋布片在折边装置4处被进行折边然后层叠在衣服面料上(具体放置在衣服面料的需要缝纫口袋的区域)；
折边板40抬升，第二送料板50沿第二导轨51后移至折边装置4处并位于折边装置下方，接着第二送料板50下降至其最低位置将布料压紧工作面，随后第二送料板50继续沿第二导轨51后移一段距离，在后移的过程中，第二送料板50始终处于其最低位置从而带动布料移动至前侧机头2处；
布料进入前侧机头2a处后，内压板21a先下降至压紧布料，第二送料板50上升并沿第二导轨51退回至初始位置，然后外压板20a再下降压紧布料并带动布料沿外圈缝线70a的轨迹移动，在移动的过程中，机针同步进行缝纫，直至完成外圈缝线70a；
外圈缝线70a完成后，前侧机头2a的外压板20a抬升，第一送料板30前移到前侧机头2a处并位于外压板20a的下方，然后再向下移动并将布料压紧后，将内压板21a抬升以释放布料，第一送料板30后移，带动布料向后移动至后侧机头2b处，此时，后侧机头2b的外压板20b和内压板21b应处于高位以便第一送料板30带动布料进入其下方；
后侧机头2b的内压板21b先压下将布料压紧，随后第一送料板30抬升并移开，后侧的外压板20b再下降至将布料压紧在工作面10上，进行内圈缝线70b的缝纫；
缝纫完成后，后侧机构的外压板20b和内压板21b抬起，通过送料滚轮60的作用布料被收料装置6收在工作面10下方。
所述缝纫状态和所述折边状态同步进行。其中，折边装置4、第二送料装置5、机头2a、第一送料装置3、机头2b同步动作流水线作业，举例来说，当某 一布料在机头2a处完成外圈缝线缝制，待第一送料装置3将布料移出并送至机头2b的过程中，机头2a立即开始对下一布料进行缝纫，与此同时，折边装置4同步开始对另一后续布料进行处理，同步顺序进行，提高效率。
由于每个机头至缝制一道缝线，使得单个口袋的缝制时间缩短，提高了效率。而且多道缝线分别采用对应的机头独立缝制，互不干涉，因而便于采用不同规格的缝线(如不同颜色的缝线)缝制，且不会增加机头复杂度。
