Abstract

470,426. Bending tubes. KIELLAND, L., IBBETSON, S. F., and GREEN, W. R. Feb. 15, 1936, No. 4693. [Class 83 (iv)] In bending tubes for curtain rails &c. a flexible mandrel comprising members formed of smooth sheet material such as a metal strip 5 and metal strips 4 with fibre facings 2 is inserted into the tube 1 which is then bent by hand about an arcuate former of channel section. The strips are manipulated and removed separately from the tube by a tool engaging in holes in the end of the strips.
