  • compressed air from a source thereof, is regulated to a predetermined pressure lower than the pressure at the source by a regulator 86.
  • This regulated pressure is conducted by a line 87 to the end of the cylinder 81 that would retract the stem 83.
  • the compressed air from the source passes through a normally-open valve 88 to a line 89 that is connected to the opposite end of cylinder 81.
  • This air is at a higher pressure than the pressure in line 87.
  • the stem 83 remains projected, causing the arms 80 to move apart and the leg forms to move to the mentioned dressing position, as in FIGS. 1 and 5.
  • Energization of a solenoid 90 closes valve 88, allowing the regulated pressure to become effective to retract the stem 83 and cause the leg forms to spread, as in FIG. 2.
  • valves 34, 79 and 88 when open, vent the respective lines 3 3, 77 and 89, thereby venting the cylinders 29, 20 and 81, respectively, at the ends where said lines are connected.
  • the mentioned solenoids are preferably controlled by any suitable programming means to time the periods of operation of the different components, as desired.
  • a suggested sequence of operation consists in dressing a pair of jeans on the leg forms 16 and over the risemounting means 14, spreading the leg forms by operating the means 21 after the clamp 19 has been applied, and operating the means 20 to clamp the waistband, opening the valve 25 to supply pressure air to the interior of the bag 17, supplying pressing steam to said bag for a required time period and, finally, returning the machine to initial dressing condition so the pressed jeans may be removed and another pair dressed thereon.
  • the dressing position of the leg forms 16 may 'be limited by adjustable stops 94 that are carried by a bracket 95 on the plate 39 and have stopping engagement with the upper gussets 44 on the form tubes 42.
