1) The material feed mechanism allows the material to be fed quickly at accuratintervals.
2) The number of button holes and the amount of feed can be set and changed with ease by operating the
touch panel. Twenty di󰀨erent patterns can be stored in memory, which enables the operator to quickly
respond to the frequent setup changes.
3) The material is automatically fed to sewing position after it has been placed on the setting position. The
machine automatically performs a series of operations, including sewing, thread trimming and stacking.
4) The operator can set the next material to be sewn while the machine is still sewing, allowing the opera-
tor to have enough time to attend on several machines.
5) Thanks to the presetting mechanism, it is possible for the operator to attend on four machines without
causing one of them to stand idle or for the operator himself/herself to become idle when two pieces of
garment are set on.
6) The clamping mechanism clamps the material securely without allowing any slippage during the sewing
operation from inserting to stacking.
7) Buttonholes can be sewn also to the front to-center strips of ladies wear.
8) The machine has various modes while enable self-diagnosis when an error occurs.
9) It is also equipped with a workpiece detector mechanism which eliminates a sewing start error.
I. MACHINE OPERATION
Mainly consisting of a sewing machine, preset board, carriage, stacker, the AC-172N-1790AN indexer is
designed to automatically carry out a series of operations starting with sewing buttonholes on the front
top-center strips of men’s shirts, etc. and ending with stacking of workpieces.
