摘要： 840,508. Feeding fibre; forming webs. FRASER & SONS Ltd., D. March 27, 1958 [April 6, 1957], No. 11303/57. Class 120(1) In apparatus for feeding fibrous material to a processing machine, the material is fed at least initially as a uniform band, narrower than the feed to the processing machine, to poweroperable means including a pinned element adapted to forward the material and including also means to accelerate the fibres of the material and distribute them evenly over the width of the feed to the machine. In one embodiment, Fig. 1, batches of fibre placed in a box 1 are formed into a band 3 which is narrower than the feed 4 of the processing machine. Band 3 is fed between conveyers 2, 6 to a spiked cylinder 7 which is doffed by a doffer 9 acting as a fan to propel the fibres up a duct 10. The delivery end 13 of duct 10 is oscillated about a horizontal axis so as to accelerate the fibres and deposit them in zig-zag fashion on feed 4. In another embodiment, Fig. 8, a fibre band 17 is fed on a conveyer 18 to an inclined spiked lattice 19 provided with a pressing roller 25, a bladed cylinder 23 for removing excess fibre and a doffer 20. The rate of fibre feed by conveyer 18 is controlled by a measuring device 26 which controls the speed of the conveyer in accordance with the mass of material per unit length. An oscillating vane 21 deflects the fibre removed by doffer 20, so as to accelerate it and deposit it in zig-zag fashion on feed 4b. In a modification,.roller 25 and cylinder 23 are omitted and fibre is fed to lattice 19 between conveyers 2, 6 as in Fig. 1.

摘要： 799,300. Opening bales of fibrous materials. FRASER & SONS, Ltd., D. Aug. 14, 1956 [Aug. 30, 1955], No. 24824/55. Class 120(3) A bale consisting of a series of laminations of hard pressed textile fibrous material is disintegrated by applying pressure steadily to opposed edge portions of the bale in the direction of the laminations parallel to the planes of cleavage, so that the laminations act as a plurality of struts and separate by buckling. The bale 1 may be arranged with laminations vertical and fed intermittently by a horizontally reciprocable ram 8 to a press in which pressure is applied to the bale by a platen 5 movable vertically towards and away from a bedplate 6. Alternatively, the bale may be fed between pairs of vertically spaced rollers arranged in tandem, the roller spacing decreasing progressively.

摘要： 759,403. Creels. FRASER & SONS, Ltd., D. March 15, 1955 [March 24, 1954], No. 8575/54. Class 120 (2). Apparatus for feeding sliver from rolls, of the type in which rolls of sliver are disposed in series in approximately end-to-end relation in a cradle constituted by parallel rollers and individually accommodated between spaced partitions disposed in parallel vertical planes transverse to the axis of the roller, is characterized in that each partition is arranged to intersect the common axis of the associated rollers at all stages of unwinding of the rolls and is formed as a sheetmetal structure with marginal edge portions which extend beyond the plane of the sheet portion. In the embodiment shown, each partition 4 consists of a web bounded, in part, by a skeleton frame 5 welded thereto and consisting of a round bar bent to form an arch, each end of the frame 5 being welded to a supporting-bar 6. In a second embodiment, the skeleton frame completely surrounds the partition which is supported to one side of the rolls 1 and 2 by a pin passing through two registering holes in the upper and lower flanges of a channel section. In other embodiments the partitions are supported from channel-shaped girders between the two rolls 1 and 2 or are hingedly supported on a rod running parallel to the rolls 1 and 2. Instead of the skeleton frame around the outside of the partitions parts of the sheet central portion may be dished outwards around the edge to form protuberances. Specification 737,421 is referred to in the Provisional Specification.

摘要： 714,195. Preparing fibres for spinning. FRASER & SONS, Ltd., D. Dec. 31, 1952 IMarch 1, 1952], No. 5448/52. Class 120(1) Apparatus for producing sliver rolls of bast or leaf fibres consists in the combination of a hackling machine or spreader 1 of the type comprising slow-moving pins, fast-moving pins and a pair of drawing rollers, and a roll former 4 including driving rollers 5, the tractive force applied to the sliver by the driving rollers and the sliver roll pressing thereon being alone used to draw the sliver band through a condensing conductor 8 mounted between the drawing rollers 2 and the roll former; the delivery rollers which are usually used to draw the sliver through the conductor are dispensed with, whereby oil-in-water emulsion sprayed through a nozzle 20 on to the sliver passing through conductor 8 is not, as previously, largely squeezed out at the nip of the delivery rollers. The peripheral speed of rollers 5 exceeds that of rollers 2. Conductor 8, which is removable, is located in position by notched brackets 10 resting on a horizontal bar 11 on the hackling machine and a clip 17 engaging a plate 16 on the roll former. An angularly adjustable plate 14 projects inwardly through each side wall 13 of the conductor to control the width of the sliver band. The end portion of the conductor adjacent rollers 2 is hinged at 18 so as to be movable downwards in the event of lapping of rollers 2, this portion of the conductor being maintained in operative position by spring catches 19.

摘要： 831,024. Preparing bast fibres for spinning. FRASER & SONS Ltd., D. Sept. 23, 1958 [Nov. 23, 1957], No. 36564/57. Class 120(1) Bast fibres, particularly slabs of hardpressed jute cuttings, are impaled on a spiked lattice over which they are evenly distributed as one flight of the lattice moves upwardly. The lattice 2 consists of endless chains spaced by transverse metallic slats carrying spikes so inclined as to impale slabs of fibres and raise them towards evener roller 7 which knocks a portion of the slab on to a conveyer 8 thereby facilitating loosening and opening of the material. The lattice 7 may travel at 270 feet per minute so that slabs are rapidly and repeatedly raised and knocked back. Partially disintegrated cuttings pass the roller 7 and are finally disintegrated as the doffer 12 deliver them to a conveyer 14.
