Definitions

  • Closing contacts CS2 extends power from switch SW1 to clutch magnet 120 in shunt with indicator lamp LP which indicates the counter is in operation.
  • Clutch magnet 120 opens contacts 124 to open the original circuit to magnet 110 and motor M1 to deenergize the clutch magnet 110 and motor Ml as soon as contacts CS1 open.
  • the cam C1 resets under control of the return spring to open contacts CS2 and close contacts CS1 and CS3; however, since contacts 124 are open, the magnet 110 and motor M1 do not reenergize at this time.
  • the spray solenoid valves SVl-SVX also do not reenergize, since contacts 114 are open. Magnet 120 in the meantime stays energized over a holding circuit through contacts 122 and CS4 to prevent closure of contacts 124 and reenergization of magnet 110 and motor M1.
  • the spray time remains constant unless altered by the operator and, therefore, the total web length passing the roll for each spray cycle will depend on both the count and the spray time.
  • the web length passing during the count cycle is constant and since the greater portion of the web passes during the count cycle any changes in web speed are reflected only to a relatively small degree by changes in web length over the entire spray cycle. This change is relatively small as may be seen from the following figures. If the web is traveling at 4,000 feet per minute, to rotate an 8- inch-diameter roll at somewhat less than 2,000 rpm, the six switch-actuating assemblies will make less than one revolution per two-thirds of a second with a 50-to-l gear reduction.
