In all cases, the minimum spacing (or pitch) is determined by the clamping tool. Two cases can be considered.

• Rigid bending parts without joints

  If continuity of contact is desired, taking into account the preceding remarks and in the most favorable case, the spacing between two successive bolts should verify :

  

  In fact, in most cases, this condition is far too restrictive; in many cases, a slight separation of the parts between two successive bolts will be accepted. The problem that arises is how to shape the parts in such a way...
