The Automatic PocketMaker replaces the manual PocketFormer.  With the Automatic PocketMaker, the ShadeSealer-168 automatically makes the pocket or hem.  Pocket depth is variable.  Pocket depth consists of two controls ... seal position and pocket diameter.  For location variations on each of the two table adjustments, click on the photo below.  To accomplish this, the Automatic PocketMaker uses table adjustments, shown here; and

Blade depth adjustments for depth.  Blade depth gage, shown below, is the distance the pneumatically controlled Blade travels to form pocket depth (pocket diameter).  To view the photo below, open any of the 6 windows on the Upper Section of the machine.  To vary depth, all Blade depth gages and Table Adjustments need to be changed.
