Patent ES-343526-A1 (ES)
Title: A method of Coating Sheet Materials with Viscous Materials
IPC: B05C/
Filed: 1967-07-28
Abstract: Flexible or semi-flexible sheet material is coated with a material having a high viscosity by extruding a suitable amount of the viscous material at substantially constant volume rate onto the peripheral surface of a roller, and rotating the roller to bring the material disposed on its surface into contact with the sheet material whereby the coating material is transferred from the surface of the roller to 'the sheet material, there being no metering of the viscous material whilst it is on the roller or on the sheet other than that achieved by the extrusion. The viscous material may be extruded onto the surface of a roller by means of an extrusion die having a suitably shaped orifice and supplied with material 'by a constant displacement pump. The opposite sides of the sheet material may be coated by extruding a suitable amount of the viscous material onto the peripheral surface of an additional second roller mounted adjacent to the first roller with its axis of rotation parallel to the axis of rotation of the first roller and rotating the second roller preferably in the direction opposite to the direction of rotation of the first roller. The sheet material may be paper, paper tissues, cellulose, metal foil, textile materials or a plastics material. The sheet material may be coated with a material having a viscosity of at least 300 centistokes e.g. 12,000 to 15,000 centistokes at a temperature which the material is applied. The viscous materials may be blends of natural .synthetic waxes e.g. petroleum waxes (paraffin waxes, microcrystalline waxes or mixtures thereof), thermoplastic polymers or co-polymers e.g. polyethylene, ethylene-vinylacetate copolymers or ethylene-ethylacrylate copolymers, natural resins e.g. rosin or rosin esters, synthetic resins e.g. polystyrene. The sheet material may be coated continuously at a rate of 50 to 500 ft. per minute. In Fig. 1 a viscous coated material is fed through feed means 1 to a constant displacement delivery pump 2 driven by a variable speed drive 3. The coated material is pumped by pump 2 through a filter 4 to extrusion die 5, and extruded through the orifice 6 of the die onto the peripheral surface 7 of heated roller 8. The material is then transferred by a rotation of the roller 8 to web 9. The tension of the web may be controlled. The coated webs are useful as packaging materials and they may subsequently bonded to a further web immediately after coating to form a laminate.

Title: Machine for making unwoven sheet material
IPC: D04H3/12
Filed: 1967-12-09
Abstract: Non-woven fabrics are made on a machine comprising a guide means for supporting and guiding a series of thread guides 18 along an endless serpentine path, means for advancing the guide means (and thus the sepentine path) along a closed path, and a means for restraining the series of thread guides 18 against movement in the closed path whilst permitting relative movement of the thread guides relative to the serpentine path. The movement of the paths results in reciprocation of the thread guides with respect to the annular path. There are also a bobbin carrier 19 to supply threads 21 to the guides 18 and a pair of parallel rollers positioned to receive the threads after they have left the guides .18. As shown, the serpentine path comprises a plurality of segments 7 mounted on a set of parallel slats 1 which are advanced around the closed path by a chain 2 fastened to their ends. The thread guides 18 are mounted on a chain 10 and the means retraining movement of the thread guides may be bars 14, 17 as shown, or driven sprockets mounted at the ends of the slats (see Fig. 6, not shown). In alternative embodiments the chain 10 may be replaced by a flexible device, and the chain may be moved in a serpentine path by sprockets mounted on cylinder or large radius. An additional stationary bobbin carrier (26), see Fig. 7 not shown may be provided to lead threads across the others so as to form triangular meshes. The non-woven fabric formed may be bonded by adhesive supplied from roll 23 or by a sheet of thermoplastic material applied to the sheet and heated and pressed thereto. In the latter embodiment, the roller 23 carries an endless belt (31) which carries perpendicular pins to receive the threads. The non-woven fabric may also be used to reinforce cellulose padding.
