Patent ES-347423-A1 (ES)
Title: Process for the production of fibers from thermoplastic synthetic material
IPC: D01D5/42
Filed: 1967-11-21
Abstract: Fibres of thermoplastic synthetic material are produced by heating a continuous moving layer of the material to fusing temperature, subsequently cooling the layer of material, and simultaneously drawing it apart in a direction transverse to the direction of movement. In one embodiment (Fig. 1) a film of thermoplastic material is embedded between two carriers 1 and 2 which are controlled by the pairs of rollers 3, 4 and 5, 6, rollers 3 and 4 being heated to fuse the raw material, and rollers 5 and 6 being arranged so that they may be displaced laterally over a large range so as to form fibres of different length. In another embodiment (Fig. 2) a film of synthetic material 7 is passed between two rollers 8 and 9, the latter being heated by a heater 10 so that the side of the material in contact with the carrier 11 and roller 9 is softened and at point 12 where the rollers move apart fibres are drawn. A cooling stream of air 13 coming from a pipe 14 having a wide slot nozzle 15 loosens the ends of the fibres attached to carrier 11 and cools them. When the fibres reach staple length they may be separated from the carrier by means of a cutting device. Stretching of the fibres may be effected by including a further pair of rollers between the pairs 3, 4 and 5, 6 of Fig. 1, whose distance apart is less than that of rollers 5 and 6. The fibres may be crimped if the rollers of one pair are made to alternatively approach and move away from each other. Materials mentioned which may be used to form fibres according to the method of the invention are polyvinyl acetate, vinyl acetate - ethylene copolymers, polyethylene, polyamides, copolyamides, polyurethane and polyvinyl chloride.

Patent ES-423475-A1 (ES)
Title: Construction of valves for bottling machines
IPC: B67C3/26
Filed: 1974-02-21
Abstract: A valve assembly for a bottling machine composed of a mechanical unit and a pneumatic assembly mounted on a single support. The mechanical assembly includes a bottle centerer which places the neck of a bottle in a suitable position in relation to the centerer and which is displaced vertically by the bottle to act on an activating valve of the pneumatic assembly to activate a pneumatic cylinder. The piston of the cylinder moves downwards and draws with it a tubular air duct to which is attached a nozzle, which moves inside a coaxial tubular channel member defining an intermediate space for the passage of liquid. The liquid is discharged at the end of the channel member, when the nozzle is in extended position to fill the bottle whereupon the liquid blocks the nozzle and prevents the exit of compressed air from the duct at a low pressure and rate. The pneumatic assembly detects this condition and reverses the cylinder, so that the air duct is retracted and the nozzle blocks the outlet of liquid from the channel member.
