  • the 60 p.s.i. air circuit is connected through a normally open mechanically actuated valve 240 and the lug 198 with the upper end of the inner cylinder 164 to exert pressure against the upper face of its piston 168 to retain the piston at the lower end of the inner cylinder and to hold it there against the 30 p.s.i.
  • the protrusion 244 moves away from the mechanical actuator of the normally open valve 240 thus opening this valve for passage of 60 p.s.i. air pressure to the lug 198 and the upper end of the inner cylinder 164 causing its piston 168 to move downwardly against the 30 p.s.i. air pressure applied to the lower face of this piston, moving the raclk 172 and rotating the pinlons 180 and 184 to move the arcuate raclr 176 and the guide wheel 204 attached thereto back to the position as shown in FIG. 1.
  • the protrusion 244 on the sheath again actuates the mechanical actuator of the valve 242 to open this valve and provide 60 p.s.i.
  • solenoid valve 4TDSV Upon expiration of the terminal delay of the terminal delay solenoid valve 4TDSV this normally closed valve opens to actuate the transfer arm whereupon at the expiration of the terminal delay of the time delay relay 4TDR (FIG. 12) its contact 4TDR1 opens deenergizing the solenoid valves 38V and 4TDSV which thereupon vent the circuit as previously described.
  • Winding apparatus comprising, winding units including at least one active unit and at least one reserve unit for successively winding a continuously advancing strand into packages, extendable carrier arm means having a free end with a strand retaining member thereon for engaging the advancing strand as it is winding on the active unit and moving it to a ready position adjacent the reserve unit, transfer arm means operable to move the strand from said ready position to winding engagement with said reserve unit, and actuating means for operating said carrier arm means.
  • said carrier arm means comprises a pair of arm members, one of said arm members having said retaining member attached thereto, and said actuating means comprises means mounting said arm members for movement generally longitudinally of each other.
  • actuating means comprises a fluid operated actuating cylinder for moving said arm members.
  • said carrier arm means comprises a cylinder, means for injecting fluid into a rear end of said cylinder, a front piston in said cylinder having a hollow piston rod and a rear piston in said cylinder having a second piston rod telescoped in said hollow piston rod, a strand engaging member mounted on one of said rods for movement relative thereto, and means for moving said retaining member relative to the one rod.
  • Apparatus as set forth in claim 4 including means for stopping forward movement of said rear piston and its rod and means permitting movement of said front piston and its rod away from said rear piston after said rear piston has so stopped.
  • Apparatus as set forth in claim 1 including means providing strand paths to said winding units, a first of said paths extending to a first of said units and past a second of said units when the first unit is the active unit, and a second of said paths terminating short of the first unit when said second unit is the active unit, a pair of said carrier arm means, one for each of the last said units for transferring the strand to the associated unit, and further including spanning means for engaging the strand along said second path and moving the strand proximate said first unit for engagement by the transfer arm means associated with said first unit 7.
  • said spannmg means comprises a plurality of fluid operated piston rods, and a strand retaining member mounted on one of said rods for movement therewith.
  • said carrier arm means comprises a cylinder and a rod movable relative to said cylinder, and a strand engaging member mounted on said rod for movement relative thereto.
  • Apparatus as set forth in claim 8 including means for controlling movement of said rod.
