Title: Method for the manufacture of felted structures
IPC: D04H1/645
Filed: 1965-11-02
Abstract: Felted structures, particularly paper maker's felts, are prepared by coating the surface of a felt cloth with a layer of water-insoluble elastomeric adhesive material and exposing the coated surface before the adhesive is dry to a current of compressed air, which is sufficient to rupture films of adhesive stretched between adjacent fibres but which is insufficient to perforate the felt.  The coated felt, e.g. a needle or non-needle felt, may be compressed before and/or after the treatment with compressed air, e.g. by passage between a pair of squeeze rollers.  The adhesive may be applied by spraying, doctor blade, or by passing the felt cloth through a pair of squeeze rollers to one of which the adhesive is applied by means of a doctor blade. The compressed air may be at an elevated temperature to assist drying of the adhesive.  The adhesive may be an elastomeric polymer of butadiene, acrylonitrile or 2-chloro-butadiene.ALSO:Felted structures, particularly paper maker's felts, are prepared by coating the surface of a felt cloth with a layer of water-insoluble elastomeric adhesive material and exposing the coated surface before the adhesive is dry to a current of compressed air which is sufficient to rupture films of adhesive stretched between adjacent fibres-but which is insufficient to perforate the felt.

Abstract: 1,259,734. Distributing and loosening crop after threshing. DEERE & CO. 30 Jan., 1970 [30 Jan., 1969], No. 4642/70. Heading A1F. [Also in Division B8] Crop coming from a threshing drum 10 is distributed and loosened by a device comprising prongs 18 which are mounted for rotation about an axle which are oscillated laterally of the direction of crop movement (i.e. in planes parallel to the axle) and which are rotated about the axle in the direction of crop movement by a rotating drum 20. In the Figs. 2 and 3 embodiment, lateral oscillation of the prongs 18 is produced by an eccentric mechanism 40, 38 causing reciprocation of a non-rotating axle 34 to which the prongs 18 are universally jointed (e.g. at 42). Rotation of the drum 20 about the non-rotating axle 34 causes rotation of the prongs about the axle 34 and varying projection of the prongs from the drum. In the Fig. 4 embodiment, lateral oscillation of the prongs 18 is effected by swash-plates 49 which are rotatably mounted on an eccentric driven shaft 48 by known means causing rocking of the plates 49, the prongs 18 being universally jointed at 52 to the swash-plates 49. The axle 48 and drum 20 can be driven independently. In a modification, baffle plates extend over the width of the drum in the region of the bores 44 and are inclined rearwardly. Double spring prongs are connected to the baffle plates and are curved rearwardly.
