  • Patent number: 7310984
    Abstract: A forming apparatus (50) includes a roll former (51) operative to roll form a metal strip (100) to form a profiled metal section (10) of generally C section profile including a pan (12) and a pair of upstanding edge margins (14 and 16). The section profile incorporates a longitudinal precamber which is introduced by the forming apparatus by incorporating a prestretching apparatus (52) upstream from the roll former (51), and a bending apparatus (53) located downstream of the roll former (51). The prestretching apparatus differentially stretches the metal strip (100) in its longitudinal direction so as to form portions (101, 102), which are more elongated than a laterally adjacent portion (103) of the strip (100). The differential stretching compensates for longitudinal shortening of the metal strip in forming the profiled section in the roll former (51). The bending apparatus (53) uses a (3) point bending process and includes a reaction stage (60), a fulcrum stage (61), and an action stage (62).

  • Patent number: 7284401
    Abstract: A system for reducing the diameter of a stent comprises a stent contracting assembly and a fluid source. The assembly comprises a plurality of contracting members that define a diameter reduction chamber for receiving a stent. When the chamber is in a pre-reduction configuration the stent has a first diameter and when the chamber is in a reduced configuration the stent has a second diameter. The second diameter is less than the first diameter. The fluid source is in fluid communication with the chamber and is constructed and arranged to inject a fluid therein. The fluid forms a fluid bearing between the contracting members and the stent which prevents the contracting members from contacting the stent in the reduced diameter configuration.
