3.  It is necessary to remove the Type-3 binding tape  on the inside seam joining the main body to the  side flap. Depending on the container construction  configuration, there are two options how to do this: •  Option 1: salvage method. With this method, the  binding tape is left undamaged and sewn back in  place after replacing the flap. A slower method,  but good if the rigger does not have the necessary  replacement tape. •  Using a seam ripper, unpick the two rows of  stitching that holds the side flap to the main  container.  [Figure A]  Start at the lower  corner and continue until approximately  2 inches past where the side flap joins the  riser cover. 2.  If option 1 was used, take the original binding tape,  fold over the seam and sew in place with two rows of  stitching. Note that there is a second row of stitching  sewn directly on top of the inside row of stitching for  reinforcement.  [Figure D]  This is very important. 3.  If option 2 was used, it is necessary to replace the  binding tape with new. Stitch down the loose end of  the binding tape at the top and then overlap the tape  by approximately 2 inches using the double needle  machine and tape binder.  [Figure E]  Overstitch the  inside row for reinforcement. 4.  Trim the bottom end of the binding tape at the corner. 5.  Note that the junction of the side flap and riser cover  is overstitched and reinforced as needed.  [Figure F] •  Remove the side flap. •  Option 2: replacement tape method. With this  method, the binding tape is destroyed during the  removal process and replaced with new. A faster  method, but new tape is required. •  Use a hot knife to melt the stitching that holds  the binding tape that attaches the side flap to  the main container.  [Figure B]  When doing  this, have the side of the tape that faces the  damaged side flap facing up in case you slip  so the wrong flap is not damaged. Proceed  to the point where the side flap stops. Trim  the melted tape at this point. •  Using a seam ripper, unpick the tape  approximately 2 inches past the end of the  side flap. Remove the side flap. 1.  Take the new flap and sew it in place on the main  container starting approximately .38 inch from the  Reassembly corner.  [Figure C]  On this design and others like it,  the lower end of the main riser cover is unstitched  during removal of the main flap. When sewing the  new flap in place, make sure that the side flap is sewn  to the main container first and then the riser cover on  top of it. Look at the opposite side to see which is on  top and duplicate. 7-47
