摘要:
A device is provided for depositing a treatment substance on the surface of a moving thread. The device comprises a tank configured to contain a liquid solution of the substance that is used to deposit the substance on the surface of the thread. The device also includes at least one nozzle having a nozzle inlet configured to receive said solution. The at least one nozzle is directed to spray the received solution towards the thread with a spray velocity in a form of jets, and the jets converge on the thread to adjust a thickness of the solution remaining on the thread by removing excess liquid entrained by the thread. The device further includes a pump that is coupled to the nozzle inlet and a treatment apparatus. The pump is configured to regulate the spray velocity according to a run speed of the thread.

Device for continuously depositing a treatment substance (20) on the surface of a thread (10), comprising: impregnation means (2) for impregnating the thread by dipping it into a bath designed to contain a solution of the treatment substance (20) in liquid form, through which bath the thread (10) runs when the device is in operation; draining means (3), placed downstream of the impregnation means (2), capable of removing the excess liquid (22) entrained by the thread; treatment means (4) placed downstream of the draining means (3), capable of making the liquid solution remaining on the thread solidify; and means (51, 52, 53, 54) suitable for guiding and running the thread (10) from the inlet to the outlet of the device along a direction df and at a speed Vf, wherein the draining means (3) include means capable of spraying said treatment liquid with an appropriately regulated velocity Vj towards the thread (10) in the form of jets (21) that converge in directions dj making an obtuse angle α with the direction df in which said thread (10) runs, so as to adjust the thickness e of liquid remaining on the thread (10) on leaving said draining means (3).
摘要:
A method of depositing a solute (34) on a metal thread (4), comprising the steps of: depositing a liquid solution (3), formed from a volatile solvent and said solute (34), on the thread (4); and then rapidly raising the temperature of the thread (4) to a temperature above the vaporization temperature of the solvent so as to vaporize the solvent placed in contact with the surface of said thread (4) and to form vapour bubbles (32) which, by expanding, generate a pressure pulse that ejects the liquid (33) remaining on the periphery of the thread.
摘要:
A device for adjusting the delivery rate of a linear element. The device forms a delivery path for the linear element between an inlet to the device at a delivery rate that is substantially constant and an outlet from the device at a delivery rate that is variable and substantially periodic and varies the length of the path of the linear element in application of a predetermined periodic relationship. The device includes a plurality of pulleys movable in rectilinear translation periodically in sinusoidal manner.
摘要:
A non-pneumatic resilient tire which derives its capacity to bear a load from laminated elements capable of supporting bending moments. The laminated elements include a stack of resilient sheets superposed and separated by a layer of rubber adhering to the latter, forming a beam capable of undergoing bending stress.

The apparatus for manufacturing a reinforcement for a tire comprises an eyelet 60 through which the cord 4 can slip; the eyelet 60 is carried by a drive mechanism 3. A guide ring 5 is positioned relative to a main arm 31 in such a manner that this passes through the ring during its cyclical movement. The ring comprises a slot 54 through which the cord passes. The ring 5 comprises a base 50, two lateral walls 51 which are rigidly connected to the base and which are disposed on either side thereof, two deflectors 52 each rigidly connected to one of the lateral partition walls disposed at the end thereof opposite the base, the two deflectors being oriented towards one another and each ending with a lip 53, the lips being of similar and opposite shapes, the slot 54 being defined by the lips of the deflectors.

摘要:
Device for embedding a thread in a rubber profiled element comprising: a continuous thread feeder arranged on a structure, a moving support able to run along the structure between a raised and a lowered position. A hollow needle, comprising a canal in which the thread runs is fixed by one of its ends to the base of the moving support in the duct, and a tip at its other end capable of penetrating the rubber profiled element, a cutter arranged on the structure, comprising a rotary blade able to cut off the thread at a given distance from the tip of the needle upon each cycle of reciprocating movement of the needle. The cutter comprises a paddle arranged behind the cutting wire of the blade and intended to fold the tail around the tip of the needle just after the thread has been cut by the blade.
摘要:
A process for manufacturing a continuous strip of self-sealing product having very low hardness, being very elastic and highly tacky, said strip being intended for feeding a converting machine, during which a thermoplastic protective film is deposited on the surface of the strip, and comprising the steps during which: a strip of self-sealing product P is extruded to a first cross section (S0), at the outlet of the extrusion die (10), the strip is surrounded over its entire perimeter using a thermoplastic film (20) by welding the film to itself, after having deposited the film (20) around the strip, the strip is calendered in order to bring it down to a second cross section (S2), smaller than the first cross section.
摘要:
Reinforcing ply (13, 14, 15) designed to produce a tire (1) formed of an assembly of threads, mostly coated with a poorly electrically conducting rubber compound (130, 140, 150), parallel with each other and making a given angle with the longitudinal direction of said ply. The ply includes through-threads (131, 141, 151) coated with one or more layers of rubber compounds, of which the outer layer is formed of an electrically conducting rubber compound. The through-threads are inserted between the threads coated with the poorly electrically conducting rubber compound (130, 140, 150) at a pitch and in a given arrangement in such a way as to form one or more electrically conducting pathways between the upper part and the lower part of the ply.
