Abstract
Abstract The present invention is directed to a godet for installation in drawing units and roller dryers used for treating natural and synthetic fibers, which comprises an outer and inner cylindrical jacket provided with a front wall, said outer and inner jacket defining a channel therebetween, means for introducing a forced flow of a heat transfer medium to the annular channel for heating the godet, and a bearing shaft means attached to the front wall of the godet by radial and axial fittings and fixedly but rotatably mounted in bearing boxes associated therewith, the metal contact surfaces of the fitting areas between the bearing shaft and the front wall of the godet being discontinuous.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
146 words
A godet for installation in drawing units and roller dryers used for treating natural and synthetic fibers, which comprises an outer cylindrical jacket provided with a front end wall, an inner cylindrical jacket spaced from said outer cylindrical jacket to define a channel therebetween, means for introducing a forced flow of a heat transfer medium to the channel for heating said godet, and a bearing shaft means attached to the front end wall of said outer jacket by radial and axial fittings, said bearing shaft means being rotatably mounted in bearing means associated therewith, said radial and axial fittings having discontinuous metal contact surfaces and interstices provided between the bearing shaft and the front end wall of the outer jacket and said interstices being filled with a heat insulating material whereby heat losses by heat transfer from the outer jacket to the shaft means are reduced.
Claim 2
Dependent Claim
146 words
A godet for installation in drawing units and roller dryers used for treating natural and synthetic fibers, which comprises an outer cylindrical jacket provided with a front end wall, an inner cylindrical jacket spaced from said outer cylindrical jacket to define a channel therebetween, means for introducing a forced flow of a heat transfer medium to the channel for heating said godet, and a bearing shaft means attached to the front end wall of said outer jacket by radial and axial fittings, said bearing shaft means being rotatably mounted in bearing means associated therewith, said radial and axial fittings having discontinuous metal contact surfaces and interstices provided between the bearing shaft and the front end wall of the outer jacket and said interstices being filled with a heat insulating material whereby heat losses by heat transfer from the outer jacket to the shaft means are reduced.
Claim 3
Dependent Claim
29 words
The godet as claimed in claim 1, wherein the axial fittings have a plurality of said metal contact surfaces each spaced from the other by one of said interstices.
Claim 4
Dependent Claim
36 words
The godet of claim 1, wherein the radial fittings have a plurality of said metal contact surfaces, each of said metal surfaces being curved and each being spaced from the other by one of said interstices.
Claim 5
Dependent Claim
21 words
The godet of claim 1, wherein the metal contact surfaces are each provided with a thin coating of heat insulating material.
Claim 6
Dependent Claim
185 words
A godet for installation in drawing units and roller dryers for treating natural and synthetic fibers, which comprises an outer cylindrical jacket provided with a front end wall, an inner cylindrical jacket spaced from said outer jacket to define a channel therebetween, means for introducing a forced flow of a heat transfer medium to the channel for heating said godet, a bearing shaft means attached to the front end wall by radial and axial fittings, said bearing shaft means being mounted rotatably in bearing means associated therewith and said radial and axial fIttings having discontinuous metal contact surfaces between the bearing shaft and the front end wall, means being located adjacent to said metal contact surfaces for preventing heat losses by heat transfer from said front end wall to said bearing shaft means, said bearing shaft means including an inner conduit means and an outer conduit means spaced from each other, and said conduit means defining an axial zone and an annular zone therebetween for the introduction and discharge of the heat transfer medium to said channel defined between the outer and inner cylindrical jackets.
Claim 7
Dependent Claim
185 words
A godet for installation in drawing units and roller dryers for treating natural and synthetic fibers, which comprises an outer cylindrical jacket provided with a front end wall, an inner cylindrical jacket spaced from said outer jacket to define a channel therebetween, means for introducing a forced flow of a heat transfer medium to the channel for heating said godet, a bearing shaft means attached to the front end wall by radial and axial fittings, said bearing shaft means being mounted rotatably in bearing means associated therewith and said radial and axial fIttings having discontinuous metal contact surfaces between the bearing shaft and the front end wall, means being located adjacent to said metal contact surfaces for preventing heat losses by heat transfer from said front end wall to said bearing shaft means, said bearing shaft means including an inner conduit means and an outer conduit means spaced from each other, and said conduit means defining an axial zone and an annular zone therebetween for the introduction and discharge of the heat transfer medium to said channel defined between the outer and inner cylindrical jackets.
Claim 8
Dependent Claim
36 words
The godet of claim 5, wherein the bearing shaft means is provided with a cylindrical inner wall and said outer conduit means is spaced from and supported by sleeve means in contact with the inner wall.
Claim 9
Dependent Claim
15 words
The godet of claim 6, wherein the sleeve means is made of a ceramic material.
