  • the tape also captures the perpendicular bisector of the triangular corner impacts.
  • These mid-perpendiculars are substantially congruent with the fold lines formed by the side edges of the hose piece. Precisely due to the too rapid depression of these folded edges, errors can occur in devices of the prior art.
