Title: Machine for expanding metal webs
Inventor: SZEGO A
IPC: B21D31/04
Filed: 1977-09-02
Granted: 1981-04-24
Abstract: A M/C for expanding rotary slit metal webs has mutually inclined triangular expander arms(81,82) over which the web is passed forwardly to spread the web and open out the slits to form diamond shaped meshes.  The angle between the arms(81,82) is made adjustable, and the arms are mounted on a subframe which pivots about a longitudinal axis.  When the angle between the arms is adjusted it is possible by tilting the sub-frame to restore the output of expanded web(58) to the horizontal plane.  The horizontal delivery of the expanded web facilitates subsequent processing and reduces the risk of damaging frail expanded webs e.g. thin metal foil webs.

Granted: 1983-12-08
Abstract: Sleeve yarn is prepared from acrylic fiber by softening, stretching, cooling, and heat-treating.  The yarn is softened at a temp. near the glass transition state, and the temp. is maintained by spraying the heated steam or gases.  It is stretched in the range of tension equal to 30% of the marginal elongation and cooled, so that the thickness is reduced to half of the original size.  The yarns following are under heat treating without tension, and are shrunk to increase the diameter of the original yarns.  The sleeve is formed in this step, and bulky property is increased by the fancy effect of the acrylic fiber.
