Abstract
Abstract A carding engine comprises a takerin (3), a card-clothed main cylinder (4) for receiving fibres from the takerin, a doffer (6) for stripping a web of fibres from the main cylinder, carding means (5) in proximity to the main cylinder to co-operate with the card clothing thereon within a first arc of cylinder rotation from the takerin to the doffer, means (7) for stripping the carded web from the doffer, and cover means (12 to 14) provided over a substantial part of a second arc of cylinder rotation from the doffer to the takerin. The cover means comprises carding elements (e.g. 16) which co-operate in a carding action with the card clothing on the main cylinder over at least part of the second arc.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
114 words
A carding engine comprising a takerin, a card-clothed main cylinder for receiving fibres from the takerin, a doffer for stripping a web of fibres from the main cylinder, carding means in proximity to the main cylinder to co-operate with the card clothing thereon within a first arc of cylinder rotation from the takerin to the doffer, means for stripping the carded web from the doffer, and cover means provided over a substantial part of a second arc of cylinder rotation from the doffer to the takerin, the cover means comprising carding elements which co-operate in a carding action with the card clothing on the main cylinder over at least part of the second arc.
Claim 2
Dependent Claim
114 words
A carding engine comprising a takerin, a card-clothed main cylinder for receiving fibres from the takerin, a doffer for stripping a web of fibres from the main cylinder, carding means in proximity to the main cylinder to co-operate with the card clothing thereon within a first arc of cylinder rotation from the takerin to the doffer, means for stripping the carded web from the doffer, and cover means provided over a substantial part of a second arc of cylinder rotation from the doffer to the takerin, the cover means comprising carding elements which co-operate in a carding action with the card clothing on the main cylinder over at least part of the second arc.
Claim 3
Dependent Claim
37 words
A carding engine according to claim 1 in which the carding elements on the cover means co-operate in a carding action with the card clothing on the main cylinder across the full width of the main cylinder.
Claim 4
Dependent Claim
63 words
A carding engine according to claim 1 or claim 2 in which the cover means has an inner surface facing towards the main cylinder, and at least part of the inner surface is spaced from the envelope of the tips of the card clothing elements on the main cylinder by no more than a distance selected of from 0.075 mm to 0.75 mm.
Claim 5
Dependent Claim
35 words
A carding engine according to claim 3 in which said part of the inner surface of the cover means is formed by the tips of card elements forming an inner part of the cover means.
Claim 6
Dependent Claim
26 words
A carding engine according to any one of the preceding claims in which the cover means is continuous around substantially the whole of the second arc.
Claim 7
Dependent Claim

A carding engine according to claim 5 in which carding elements are provided over part only of the inner surface of the cover means.
Claim 9
Dependent Claim
77 words
A carding engine according to any one of claims 1 to 4 in which the cover means is discontinuous and comprises a plurality of sections each extending around part of the second arc and across the full width of the main cylinder, adjacent sections being spaced apart around the circumference of the main cylinder to leave a space extending the full width of the main cylinder and parallel to the axis of rotation of the main cylinder..
Claim 10
Dependent Claim
19 words
A carding engine according to claim 8 in which a screen is mounted in.a space between adjacent cover sections.
Claim 11
Dependent Claim

A carding engine according to claim 8 or claim 9 in which at least one of the cover sections has carding elements provided over the whole of its inner surface.
Claim 12
Dependent Claim
30 words
A carding engine according to claim 8 or claim 9 in which at least one of the cover sections has carding elements provided over part only of its inner surface.
Claim 13
Dependent Claim
53 words
A carding engine according to any one of claims 8 to 11 in which each cover section is a composite structure comprising a plate having a substantially smooth inner surface, and a segment having carding elements, the segment lying immediately downstream of the plate in the direction of rotation of the main cylinder.
Claim 14
Dependent Claim
17 words
A carding engine according to claim 12 in which the segment comprises at least one flat bar.
