Definitions
- the present invention relates to machines for forming patterns on a nonwoven and to sleeves and methods of manufacturing a sleeve for machines of this kind.
- WO 01/25522 A1 describes a machine for forming patterns on a nonwoven which comprises a rotary drum whose interior communicates with a source of vacuum. The rotating drum has slots on the side surface. It is surrounded, in addition to a perforated covering, with an openwork sleeve having a succession of raised and recessed patterns.
- the openwork sleeve is made of bronze canvas.
- the invention remedies this by a technical solution whose longevity is greater.
- the invention relates to a machine for forming patterns on a nonwoven which comprises a rotating mounted drum whose interior communicates with a vacuum source, which is provided with slots on the lateral surface and which is surrounded by a openwork sleeve in bronze, brass, stainless steel or copper canvas with a succession of raised and recessed patterns.
- the sleeve is coated with a layer of nickel or copper, obtained in particular by electrolysis, and preferably having a thickness of 50 ⁇ m to 500 ⁇ m.
- the sleeve is made of bronze coated with nickel.
- the sleeve has an opening rate of 5 to 50%, the opening rate being defined by the ratio of the surface of the openings of the sleeve to the total surface of the sleeve.
- the rotary drum is surrounded by a perforated coating and this perforated coating is itself surrounded by the perforated sleeve according to the invention.
- the perforated covering may have perforations with a diameter of 0.5 to 5 mm and the distance between two consecutive perforations may be between 1, 5 and 12 mm.
- This coating can be made of steel, or bronze or plastic.
- the invention also relates to a method of manufacturing the perforated sleeve.
- This process consists in arranging by embossing relief and hollow patterns on a canvas of bronze, brass, stainless steel or copper, to conform by welding two opposite edges the canvas into a blank of sleeve, to mount the blank on a rotating support cylinder and immerse it in an electrolytic nickel or copper deposition bath until electrodeposition of a nickel or copper layer and remove the openwork sleeve from the bath. While the blank is immersed in the bath, it is rotated on the support to obtain an electrolytic deposit of nickel or copper as uniform as possible. We could not deposit nickel directly on the bronze canvas because then the conformation of the bronze canvas into a sleeve would break the thin layer of nickel or copper.
- the invention finally relates to an openwork sleeve made of a canvas of bronze, brass, stainless steel or copper forming non-perforating patterns in relief and in hollow, characterized in that the fabric 30 is coated with a layer of nickel or of copper.
- the embossing of the sleeve gives it non-perforating patterns such that the difference in level between the highest point and the lowest point of a pattern, counted according to the thickness of the wall, is between 0.5 mm and 5 mm, in particular between 1 and 5 mm.
- the sleeve of circular cross section has in particular a wall thickness of between 1.5 and 7 mm.
- FIG. 1 illustrates a production line for a nonwoven incorporating a machine according to the invention
- FIG. 2 is a partial sectional view illustrating the machine according to the invention
- a production line making it possible to produce a nonwoven according to the process according to the invention essentially consists of an assembly, designated by the general reference (1), making it possible to produce by carding, by covering with continuous filaments or other similar technique, a sheet which may consist of fibers or continuous filaments or a mixture of fibers and continuous filaments of synthetic, artificial or natural material, in particular polyester, polypropylene, viscose, polyacid lactic, cotton, polyvinyl alcohol, wood fibers, either synthetic fibers or natural fibers.
- a porous conveyor belt (11) constituted for example by an endless fabric made of synthetic monofilament, in particular polyester, which has a porosity between 20 and 60%, that is to say a ratio between the solid surfaces and the empty surfaces of between 20 and 60%, preferably close to 30%.
- This porous support (11) is associated, in a manner similar to the teachings of FR-A-2 730 246, with a set of treatment by water jets making it possible, on the one hand, to ensure compression and wetting of the sheet (10) formed and, on the other hand, subjecting this sheet to the action of ramps of water jets.
- Such an assembly essentially comprises a rotary cylindrical drum designated by the general reference (20) bearing against the surface of the conveyor belt (11).
- a first ramp of water jets (21) is disposed below the support (11) and makes it possible to pre-wet the sheet (10).
- This ramp is arranged at a distance of between 70 and 100 mm from the porous support (11) and forms a curtain of water making it possible to wet the compressed sheet and causing a first light entanglement of the sheet.
- the drum (20) consists of a conventional rotary cylinder with a honeycomb structure (not shown in the appended figures), which is covered with a metal sheet (22) comprising micro-perforations, distributed randomly on its surface or by a woven surface.
- This rotary cylinder surrounds a second coaxial cylindrical drum (23) fixed, hollow, connected to a source of partial vacuum to form a suction box, the suction being exerted through slots (26) located opposite the area of action of water jets.
- the sheet (10) is subjected to the action of pressurized water jets (27) coming from two conventional ramps (24, 25) .
- These ramps (21, 24, 25) are formed of contiguous injectors arranged at predetermined distances from each other.
- the drum has a slot (26) which extends over the entire length of a generator, the width of which is generally between 5 mm and 30 mm and across from which the water from the jets (27) is recovered.
- a second assembly (28) produced in accordance with the invention, and the general structure of which is shown in FIG. 2.
- This assembly (28) is constituted by a rotary suction drum (29), also constituted by a cylindrical honeycomb structure, not shown in the figure, and which supports a perforated cylindrical covering (29).
- the perforations of this covering (29) may have a diameter of 3 mm, the distance between two consecutive orifices being 4 mm and the orifices being offset from one row to the next.
- the perforated covering (29) is covered with an openwork sleeve (30), in the form of a sleeve, having a succession of raised and recessed areas.
- This openwork sleeve (30) is constituted by an openwork canvas in bronze threads, comprising an opening rate of between 10% and 50%, said canvas having been embossed, in order to comprise a succession of raised and non-perforating hollow zones.
- These raised and recessed areas may have a regular structure, for example a herringbone shape or a configuration forming irregular patterns.
- the fabric (30) is coated with a layer of nickel 50 to 500 microns thick obtained by electrodeposition as follows: the perforated coating (cylinder) (29) coated with its perforated sleeve (30) is mounted on a rotary support.
- the sleeve (30) is partly immersed in an electrolyte contained in a galvanic deposition tank.
- a nickel electrode, immersed in the electrolyte is connected to the cathode of a direct current generator.
- the sleeve (30) is connected to the anode of the same current generator via a rotary collector which ensures the passage of current during the rotation of the sleeve (30).
- the nickel from the cathode migrates into the electrolyte and is deposited on the sleeve connected to the anode.
- a motor drives the sleeve (30) mounted on its support in rotation to obtain a fine and uniform deposit over the entire surface of the sleeve (30).
- the pre-bonded sheet is restructured by the action of one or more series of jets, coming from two conventional hydraulic injectors in the present case. Under the action of these jets, the ply conforms to the configuration of the raised and hollow areas of the perforated sleeve (30).
- the treated sheet (31) is brought to a conveyor (32) where the water is removed, for example using a suction box placed below the conveyor (32), then it is dried by passage on a through air cylinder (33) and having a temperature of the order of 150 ° C before being received in the form of a winding (34).
