Materials: 9 files consist of 4 double pages each, each card measuring 148x105mm, two cotton tapes of about 1cm wide, cotton yarn, steel needle.
Procedure: The basic stitch is a chain described above, but instead the thread stitching along the fold down to two internal tapes cotton about an inch in width with the following ways:
-frame is prepared for binding wood setting, with pins, two cotton webbing so that they are a1, 5.cm cut head and 2 cm
-references are created for the holes in the chains along the fold seam of the first file that is placed with the cutting head to the right and folding seam towards you
-enter the thread in the first issue through The reference by the cut of a foot and moves toward the cutting head
-joint at the first tape, the thread exits immediately right to the tape the outside and within the fold seam just to the left of the same tape
-thread continues along the inside seam of the fold and fixed with a suitable mode to the second tape, then come close to the hole cut foot thread enters the fold of the seam of the second file and you do the same operations
first-and second file is then secured with a double knot in chain stitching as
-the third file is placed over the first two, the thread enters the fold of sewing and exit to the right of first tape: here, instead of returning immediately to the left of the webbing, the needle enters the transition wire created around the first tape of the first set from the top down and went out and returned to the left of the first tape of the file in place
-this operation is repeated for the second tape of the third file and for all following files to the third last, the third issue, also, the files are made solid by the chains
- in the last two sets the stitching thread, passing around the tapes, not to step down earlier in the file, taking the characteristics of the passages in the first two sets
Characteristics of a suitable sewing on tape: Through the referendum within the fold of stitching must be very tight and not move if pinched by the fingers, taking the body of the book with the thumb and index finger over the cut on the back of this head should not move excessively when excited with opposite directions with both hands, the tapes, released from the frame, must run, albeit with difficulty, through the spaces created by the referendum, the webbing must not be damaged from the needle stitching.
