Abstract
Abstract An improved cleaning device for textile fibres is provided comprising at least one carding drum and a taker-in cylinder or drum in tangential arrangement with a lower peripheral portion of the carding drum, the taker-in drum having cooperatively associated therewith means for feeding textile fibres thereto for subsequent delivery to the carding drum for further treatment thereof. The improvement resides in employing at least a pair of first and second cleaning cylinders tangentially located at a lower peripheral portion of the taker-in drum, the first cleaning cylinder being tangentially associated with the second cylinder. The rotation of the taker-in drum is such as to cause textile fibres fed thereto to pass as an outer layer around the first cleaning cylinder and from there to the second cleaning cylinder and then back to the taker-in drum for delivery to said carding drum, the speed of one of the cleaning cylinders relative to the other and to the taker-in drum being such as to remove particles therefrom by centrifugal force while returning workable fibres to the taker-in drum for delivery to the carding drum for further treatment.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
204 words
In a cleaning device for textile fibres comprising at least one carding drum and a taker-in cylinder or drum in tangential arrangement with a lower peripheral portion of said carding drum, said taker-in drum having cooperatively associated therewith means for feeding textile fibres thereto for subsequent delivery to said carding drum for further treatment thereof, the improvement which comprises: at least a pair of cleaning cylinders located at a lower peripheral portion of said taker-in drum and tangential thereto, one of said cleaning cylinders being tangentially associated with said other cleaning cylinder, the rotation of said taker-in drum being such as to cause textile fibres fed thereto to pass around said drum and provide an outer layer thereof for transfer to one of said cleaning cylinders and from there to the other cleaning cylinder and then back to said taker-in drum for delivery to said carding drum, the speed of rotation of one of said cleaning cylinders containing the outer layer relative to the speed of the other cylinder and to the speed of said taker-in drum being such as to remove particles therefrom by centrifugal force while returning workable fibres to said taker-in drum for delivery to said carding drum for further treatment.
Claim 2
Dependent Claim
204 words
In a cleaning device for textile fibres comprising at least one carding drum and a taker-in cylinder or drum in tangential arrangement with a lower peripheral portion of said carding drum, said taker-in drum having cooperatively associated therewith means for feeding textile fibres thereto for subsequent delivery to said carding drum for further treatment thereof, the improvement which comprises: at least a pair of cleaning cylinders located at a lower peripheral portion of said taker-in drum and tangential thereto, one of said cleaning cylinders being tangentially associated with said other cleaning cylinder, the rotation of said taker-in drum being such as to cause textile fibres fed thereto to pass around said drum and provide an outer layer thereof for transfer to one of said cleaning cylinders and from there to the other cleaning cylinder and then back to said taker-in drum for delivery to said carding drum, the speed of rotation of one of said cleaning cylinders containing the outer layer relative to the speed of the other cylinder and to the speed of said taker-in drum being such as to remove particles therefrom by centrifugal force while returning workable fibres to said taker-in drum for delivery to said carding drum for further treatment.
Claim 3
Dependent Claim
40 words
The cleaning device of claim 1, wherein said pair of cleaning cylinders include first and second cylinders, and wherein said first cleaning cylinder is located down-stream of said second cleaning cylinder in the direction of rotation of said taker-in drum.
Claim 4
Dependent Claim
28 words
The cleaning device of claim 2, wherein a means is provided between the first and second cleaning cylinders to facilitate the passage of fibres between said cleaning cylinders.
Claim 5
Dependent Claim
52 words
The cleaning device of claim 3, wherein the direction of rotation of each of said cleaning cylinders is opposite to that of the taker-in drum, the peripheral speed of the second cleaning cylinder being less than the peripheral speed of the taker-in drum and greater than that of the first cleaning cylinder.
Claim 6
Dependent Claim
213 words
In a cleaning device for textile fibres comprising at least one carding drum and a taker-in cylinder or drum in tangential arrangement with a lower peripheral portion of said carding drum, said taker-in drum having cooperatively associated therewith means for feeding textile fibres thereto for subsequent delivery to said carding drum for further treatment thereof, the improvement which comprises: at least a pair of first and second cleaning cylinders located at a lower peripheral portion of said taker-in drum and tangential thereto, the first cleaning cylinder being tangentially associated with said second cylinder, said first cleaning cylinder being disposed downstream of said second cleaning cylinder relative to the direction of rotation of said taker-in drum, the rotation of said taker-in drum being such as to cause textile fibres fed thereto to pass around said drum and provide an outer layer thereof which is transferred to said first cleaning cylinder and from there to said second cleaning cylinder and then back to said taker-in drum for delivery to said carding drum, the speed of said first cylinder relative to said second cylinder and to said taker-in drum being such as to remove particles therefrom by centrifugal force while returning workable fibres to said taker-in drum for delivery to said carding drum for further treatment.
Claim 7
Dependent Claim
213 words
In a cleaning device for textile fibres comprising at least one carding drum and a taker-in cylinder or drum in tangential arrangement with a lower peripheral portion of said carding drum, said taker-in drum having cooperatively associated therewith means for feeding textile fibres thereto for subsequent delivery to said carding drum for further treatment thereof, the improvement which comprises: at least a pair of first and second cleaning cylinders located at a lower peripheral portion of said taker-in drum and tangential thereto, the first cleaning cylinder being tangentially associated with said second cylinder, said first cleaning cylinder being disposed downstream of said second cleaning cylinder relative to the direction of rotation of said taker-in drum, the rotation of said taker-in drum being such as to cause textile fibres fed thereto to pass around said drum and provide an outer layer thereof which is transferred to said first cleaning cylinder and from there to said second cleaning cylinder and then back to said taker-in drum for delivery to said carding drum, the speed of said first cylinder relative to said second cylinder and to said taker-in drum being such as to remove particles therefrom by centrifugal force while returning workable fibres to said taker-in drum for delivery to said carding drum for further treatment.
Claim 8
Dependent Claim
27 words
The cleaning device of claim 5, wherein a means is provided between the first and second cleaning cylinders to facilitate the passage of fibres between said cylinders.
Claim 9
Dependent Claim
50 words
The cleaning device of claim 5, wherein the direction of rotation of said cleaning cylinders is opposite to that of the taker-in cylinder, the peripheral speed of the second cleaning cylinder being less than the peripheral speed of the taker-in cylinder and greater than that of the first cleaning cylinder.
