A plurality of inward and outward folding bars are automatically positioned relative to the airbag and transferred to interleaving positions to fold the airbag.

Airbag folding apparatus

In a mixing head for mixing plural kinds of liquid materials, a first forward movement passage for opening a discharge control valve which control supplying the liquid materials into a mixing chamber, is ramified from a second forward movement passage for closing a circulation control valve which controls the circulation of the liquid materials, and extends across a spool of the circulation control valve. The spool is provided with a groove for opening the first forward movement passage when the circulation control valve is in a closed state. Further, a restriction passage having a check valve for keeping a working fluid from flowing into a first cylinder including a first piston of the discharge control valve, is formed to be communicated with the first cylinder at a side of the first forward movement passage and is ramified from the second forward movement passage.
