Abstract
Abstract An apparatus for regulating the surface temperature of a plurality of revolving and substantially identically constructed and arranged heated devices, such as godets or thread rollers in textile machines, wherein a guide or monitor godet is provided in which two means of detecting and transmitting temperature data are used in conjunction with each other as a reference for effectively controlling the surface temperature of all other heated godets in the system.

Claim 1
Independent Claim
285 words
In a textile machine having a plurality of revolving heated godets of substantially identical wall construction and having substantially identical rotatable heating means for heating a plurality of threads or the like in running contact on the surface of each godet, the improvement for accurately controlling the temperature of the thread-contacting surfaces of all of said godets in a common system which comprises: a. at least one monitor godet containing a first heat sensor embedded in the wall of the godet and rotating therewith and embedded in the wall of the godet and rotating therewith and a stationary heat sensor mounted in proximity to the heated thread-contacting wall surface of the monitor godet; b. a plurality of other godets in a common system with said monitor godet, said other godets containing a stationary heat sensor mounted in proximity to the heated thread-contacting surface of the godet wall in substantially the same position as said stationary heat sensor of said monitor godet; c. an electrical heating means in each of said monitor godet and said other godets to supply heat to the thread-contacting surfaces of said godets; d. a preset temperature refErence means; e. a first regulator means responsive to said embedded heat sensor of the monitor godet and to said preset temperature reference means to regulate the amount of heat supplied to the thread-contacting surface of said monitor godet through its heating means; f. a second reference means responsive to said stationary heat sensor of the monitor godet; and g. a second regulator means for all other godets responsive to said second reference means to regulate the supply of heat to the thread-contacting surface of all of the other godets through their individual heating means.

In a textile machine having a plurality of revolving heated godets of substantially identical wall construction and having substantially identical rotatable heating means for heating a plurality of threads or the like in running contact on the surface of each godet, the improvement for accurately controlling the temperature of the thread-contacting surfaces of all of said godets in a common system which comprises: a. at least one monitor godet containing a first heat sensor embedded in the wall of the godet and rotating therewith and embedded in the wall of the godet and rotating therewith and a stationary heat sensor mounted in proximity to the heated thread-contacting wall surface of the monitor godet; b. a plurality of other godets in a common system with said monitor godet, said other godets containing a stationary heat sensor mounted in proximity to the heated thread-contacting surface of the godet wall in substantially the same position as said stationary heat sensor of said monitor godet; c. an electrical heating means in each of said monitor godet and said other godets to supply heat to the thread-contacting surfaces of said godets; d. a preset temperature refErence means; e. a first regulator means responsive to said embedded heat sensor of the monitor godet and to said preset temperature reference means to regulate the amount of heat supplied to the thread-contacting surface of said monitor godet through its heating means; f. a second reference means responsive to said stationary heat sensor of the monitor godet; and g. a second regulator means for all other godets responsive to said second reference means to regulate the supply of heat to the thread-contacting surface of all of the other godets through their individual heating means.
Claim 3
Dependent Claim
49 words
An improved textile machine as in claim 1, wherein said second regulator means includes a series of regulators, said regulators being connected by means of a double-throw switch either to said second reference means or to a third adjustable reference, which can be manually set to a predetermined value.
Claim 4
Dependent Claim
19 words
An improved textile machine as in claim 2, wherein the double-throw switch is an electrically or electronically controlled relay.
Claim 5
Dependent Claim
19 words
An improved textile machine as in claim 3, wherein the double-throw switch is connected to an adjustable timing device.
Claim 6
Dependent Claim
68 words
An improved textile machine as in claim 3, wherein the double-throw switch is connected to a signal-comparing means which brings about the transfer from the godet-controlled adjustable reference, influenced by the monitor godet stationary heat sensor, to the predetermined value reference, when the difference between the two signals delivered by these references is less than a preset value, this value selected according to the precision of regulation desired.
Claim 7
Dependent Claim
38 words
An improved textile machine as in claim 5, wherein the predetermined reference is connected to a readjusting device which readjusts the predetermined reference value automatically, depending on the value determined by the heat sensor of the monitor godet.
Claim 8
Dependent Claim
69 words
A monitor godet for use in the machine of claim 1, wherein the embedded heat sensor which rotates with the godet is connected by slip rings and brushes or by induction coils to the remainder of the measuring and regulating circuit, and the stationary heat sensor is inserted into a U-shaped groove or recess cut in the godet wall, concentrically surrounding the axis of rotation of the heated godet.
