Trimmer Test  

Figure 1 - AMTRIM01A Test Design

The primary purpose of the AMTRIM01A test design is to test the trimmer and grabber functions.  The goal in using this design to verify trimmer adjustments is to reduce trimmer errors down to the absolute minimum possible.  If you have more than one trimmer related error for the entire design, you should adjust the trimmer assembly accordingly and then re-sew the AMTRIM01A on a different location of the fabric.  

It is further recommended that you make any necessary adjustments to eliminate thread break problems while this design is running.  It is recommended that this design is run while you observe it so you see the machine behavior at the time machine errors occur in this design.  However, the primary focus of this design is to detect and eliminate trimmer and grabber related errors.

The trimmer test should be sewn with not more than one problem for the entire design.  It should be sewn on one layer of white broad cloth (Melco PN: 344754-01) (or any white polyester material) or the equivalent with one layer of backing (ARC PN: C20162210).
