Definitions

  • a temperature sensor for a rotating heater r011 having an annular slot cut into an end face of the roll including a non-inductive winding of temperature-responsive resistance wire upon a stationary rim inserted completely within the slot in non-contacting relationship whereby the heat of the roll affects the winding to change its resistance to control and regulate the source of heat provided for the roll.
  • thermocouples and thermistors placed'in the proximity of the rotating roll were sufficient: however. as the requirement for closer heat regulation arose in view of the ever more heat sensitive synthetic materials from which the filaments were drawn. innovations were introduced for more accurately measuring the roll temperature.
  • United States Patent 3.273.101 wherein an annular slot is cut into one face of the rotating roll and a heat stationary probelilte sensing element is inserted within the slot but not in contact with it. leads from the sensing element being connected with the heater control circuit. which may be via electric resistance devices placed inside the roll. or via induction heating of the roll by an internal winding energized by alternating current. both types of heating rotating rolls being well understood in the art.
  • United States Patent 3.435.171 shows a similar adaptation in connection with an inductively heated metal fiber heating roll. or godet.
  • United States Patent 3,484,581 illustrates another arrangement whereby the temperature of the roll is provided by a temperature-responsive resistance winding integral with one end of the heater roll. its leads being brought out to a stationary control circuit via slip rings and the like.
  • the present invention eliminates the deficiencies and disadvantages noted above in providing a simple. highly accurate. temperature sensor arrangement for a synthetic fiber heat processing roll by incorporating a continuous thermal sensitive winding constantly related to the heated roll throughout its entire lateral surface as it rotates by providing an annular slot cut into one face of the roll into which an annular. non-inductive. temperature-responsive resistance winding is inserted. the winding being carried by a stationary mounting rim extending into the slot.
  • the drawing illustrates the invention in the showing of a partial sectional view of a cylindrical heater roll 10. which as it is rotated contacts synthetic fiber filaments being processed upon its lateral surface 11.
  • a cylindrical heater roll 10 which as it is rotated contacts synthetic fiber filaments being processed upon its lateral surface 11.
  • At one end of the roll 10. preferably its open end which normally abuts the fixed support from which the roll is rotated by a shaft (not shown) extending internally of the roll and connected therewith at the closed end of the roll.
  • an annular slot 12 is cut into the face 13.
  • a ring 14. which is stationary in respect to the roll 10. having a rim 15 throughout its circumference. is provided with a winding 16 of one or more complete turns of temperatureresponsive resistance wire.
  • the resistance wire may be iron.
  • the winding is preferably made by joining two lengths of wire together (electrically) at their ends and winding the two wires together upon the rim 15 to provide a non-inductive winding, thereby avoiding any electrical interference when the roll 10 may be inductively heated by an internal winding (not shown) excited with alternating current.
  • the free ends of the winding 16 are brought out and connected with the control circuit for regulating an electrical source of heat provided to the heater roll 10.
  • Temperature sensing apparatus for a rotating heater roll including an annular slot cut into one face of said toll. a stationary circumferential member inserted into said slot in non-contacting relationship. and a temperature-responsive resistance winding extending into said slot upon said member for detecting changes of temperature of said roll.
