Patented June 17, 1952 CARDING ENGINE WITH SECONDARY TAKER-IN George Clapperton, Bolton, England, ass'ignor to Nuclotex Limited, Bolton, England Application September 30, 1948,-Serial No. 52,009 In Great Britain July 31, 1948 Claims.

This invention relates to improvements in carding engines for cotton or other fibres.

According to the invention a secondary takerin roller is arranged below the primary taker-in roller, the secondary taker-in roller being smaller in diameter and having a greater peripheral speed than the primary roller and being so disposed in relation thereto and to the card cylinder that it removes all or the greater part of the fibres from the primary roller and delivers them to the card cylinder.

The secondary taker-in roller is covered with metal wire clothing similar to but preferably 'finer than that of the primary roller.

The invention is illustrated in and will be described with reference to the accompanying drawing which shows a longitudinal section of sufficient of a carding engine for the invention to be understood. V

In the drawing A is the usual card cylinder, a. the card cylinder shaft, B the travelling flats, C the primary taker-in roller, D the feed plate and d the feed roller all of which are of usual known construction and arrangement.

A secondary taker-in roller E is mounted below the primary taker-in roller C in bearings carried in the side frames of the machine.

These bearings are preferably adjustable to allow of adjustment of the roller in relation to the primary roller C and the cylinder A.

The secondary taker-in roller E is covered with metal wire clothing e similar to but preferably finer than the clothing c of the primary roller C.

The roller E is smaller in diameter than the roller C and is rotated at a greater surface speed than the latter roller. The two rollers C and E rotate in the same direction as each other but in the opposite direction to the rotation of the card cylinder A. Thus, the wires e of the roller E are travelling in the opposite direction to the wires 0 of the roller C at the point Where they interact.

Suitable diameters and speeds of rotation of primary taker-in roller C and secondary taker-in roller E co-operating with a carding cylinder of 50%" diameter rotating at 160 revs. per minute are: roller C 9%" diameter 400 revs. per minute, roller E 4%" 1260 revs. per minute. It is to be understood that these diameters and speeds are only given by way of example and the invention is not limited thereto.

Mote knives c are arranged in the usual position below the primary taker-in roller C and a casting C carrying the grid bars 0 extends from the front mote knive c to a position near the periphery of the secondary taker-in roller E.

Mote knives e are arranged below the secondary taker-in roller E in substantially the same relative position thereto as are the mote knife 6 to the roller C and the space between the front mote knife e and the card cylinder is covered by a curved metal casing E carrying transverse grid bars 6 A curved casing G, bolted or otherwise aflixed to the frame sides, extends from the rear mote knife e to the casing C below the primary takerin roller C and a making-up piece G of approximately triangular shape is arranged in the space formed between the two taker-in rollers C and E and card cylinder A.

The fibres are fed to the primary taker-in roller C in the usual way by the feed roller (1 and are carried round by the roller C to the point where the latter meets the secondary taker-in roller E. The wires 6 of the roller E, which at this point are moving in the opposite direction to the wires 0 of the roller C, then remove most of the fibres from the wires 0 and carry them round passedthe casing G andmote knives e to the card cylinder A the wire clothing of which removes them therefrom in the usual way. Any fibres not removed from the wires 0 of the primary taker-in roller C by the wires e of the secondary taker-in roller E are carried forward by the roller C to the card cylinder A.

A carding engine provided with a secondary taker-in roller C arranged and operating as hereinbef'ore described has an additional cleaning effect on the fibres and also produces a combing or paralleling action thereon between the two taker-in rollers.
