Apparatus for the forming of hair

Apparatus for forming hair, comprising:

• a hair forming tool provided with a casing having a first opening, at least one first duct in said casing and a first chamber communicating with said first duct, a suction device for creating an underpressure in said first duct and communicating with said first duct through said first chamber, said first opening serving for the introduction of a strand of hair into said first duct and into said first chamber, a second chamber surrounding said first chamber and forming part of at least one second duct communicating with ambient air, heating means in said second duct, said second duct having a second opening adjacent said first opening for passage of air from said heating means through said second duct into said first chamber, said second chamber via said second opening surrounding said first opening having a first connection with the first duct, and also having a second connection with the second duct for the supply of air, so that when there is an underpressure in said first duct, air rushes in via said first opening and via said first connection partly directly from the ambient air and partly from said second chamber and through said first duct to said first chamber, and timing means connected to said heating means for keeping the same in operation for a first predetermined period of time and for discontinuing operation for a second predetermined period of time, and also connected to said suction device for keeping the same in operation even when said heating means is inoperative.
