  • the unpaired end of left end bar 72 is fastened to end mount 42.
  • the pins 78 extend downwardly into vertical holes in nut blocks 92 located on the under side of plate 26.
  • the nut blocks 92 are horizontally bored and threaded to accommodate oppositely threaded drive screws 94 which are connected at their inner ends by couplings 96 to a low speed shaft extension of gear motor 98.
  • An upper guide assembly 102 is constructed in the same manner as lower guide assembly 28 except that it does not include side guide plates 67 and is also mounted for vertical movement.
  • air motors 104 are pivotally connected to the cross tie 22 adjacent each of the side plates 20.
  • Piston rod 1% of each motor 104 is connected to a two-arm lever 108 which is pivotally mounted intermediate its ends on a shaft 110 extending between and fastened to the side plates 20.
  • the lower end of each lever 108 is pin connected to a clevis 112 fastened to the plate 26 of the upper guide assembly 102.
  • Power for driving synchro-motors 98 and 98 is supplied by a synchro-generator 126 which is driven from a standard AC. motor 122 through a gear reducer 123.
  • the gear reducer permits the generator to operate at a speed low enough to prevent the synchro-motors from getting out of phase.
  • Power for driving the motor 122 is supplied by lines L1, L2 and L3.
  • a third synchro-motor 12 i is also powered from the synchro-generator 12 h.
  • the motor 124 drives a dial indicator 125 which shows the exact distance between the edge guides 66.
  • the control for operating the valve 54- and motors 98, 98 and 124 are shown in FIGURES 7, 8 and 8a.
  • the control includes push button switches 126 and 128 which are connected in series with relay coils 130 and 132, respectively.
  • Relay coil 131? has a normally closed contact 13ilC in series with relay coil 132, normaly open contact 13tlC1 and normaly closed contact 13002.
  • Relay coil 132 has normally closed contact 132C connected in series with relay coil 13%), normally open contact 132C1 and normally closed contact 132C111.
  • Contacts 136C1 and 132C1 are connected in parallel with each other and in series with valve solenoid 54S.
  • Contact 13ilC2 is connected in series with time delay relay 134.
  • Contact 132C2 is connected in series with time delay relay 136.

  • a strip S passes in the direction of the arrow between the upper and lower guide assemblies 28 and 162.
  • the edge guides 66 center the strip entering the rolls and the wooden blocks provide the necessary drag on the strip.
  • the clamp devices 52 and 52 prevent movement of the boards and board mounts at this time.
  • air is delivered to the blind end of motors 104, thus moving the top guide assembly 102 upwardly.
  • the assembly 162 is lowered to clamp the top assembly 102 down on the strip S.
  • the push button switch 126 is closed, thus energizing relay 139 which opens contact 136C so as to prevent operation of relay coil 132.
