An apparatus and method is described for automatically folding airbags a plurality of times in stages of predetermined width. Both longitudinal and lateral folds may be accomplished. 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.

Mixing head

A mixing head of an injection molding machine has an injection plunger for opening and closing a plurality of orifices and a spool plunger for opening and closing a plurality of circular passageways. The plunger and the spool are disposed parallel to each other.

In a stirring device of liquid material, of circulation type comprising a return pipe inserted in a stirring tank, and a feeding pipe connected to bottom portion of the stirring tank, so that the liquid material fed through the feeding pipe is returned to the return pipe, an expanded part having inner diameter larger than that of the return pipe is provided at top end of the return pipe, and plurality of holes having the total opening diameter larger than the lateral sectional area of the return pipe are bored on both sides of outer circumferential portion of the expanded part. Two reverse circulation streams in the horizontal direction are formed within the circulation tank, and the liquid material is circulated through the feeding pipe and the return pipe, thereby the stirring is performed well without involving the excessive air.
