CAUSES OF BAD ASSEMBLING
The main sources of trouble of the assembling are transpositions and matrices jumping out of the assembler. The causes of these troubles are numerous. In the assembling elevator it may be caused by worn buffer strips, detaining pawls not working properly, or worn detaining plates. On the assembler plate trouble may be caused by a worn star wheel, dirty star wheel friction, chute spring out of adjustment, matrix catch spring out of adjustment, chute rails loose from the plates; assembler slide brake out of adjustment, permitting the slide to vibrate; brake catching too soon, not allowing the slide to return all the way back; loose screw in assembler slide operating brake, causing the slide to bind; or assembler slide worn or dirty, which will not allow the brake to operate properly.
These are some of the principal causes of trouble, but due to wear or the care the machine has had, there may be numerous other causes.
