Abstract: The invention relates to equipment for producing a non-woven web, comprising a device (107, 108) for driving a filament packet, using an air stream, towards a conveyor (101) and an electrostatic device (117) arranged so as to apply electrostatic forces to the filaments of the driven packet, characterised by a means (801, 804) for removing dust from the driving air stream.

Abstract: The invention relates to a spunbond tower that includes a die (103), a device (106) for cooling the filaments formed by the die, a device (107) for stretching the cooled filaments, a system (108) for forming a non-woven web (110) on a mat, said system including an electrostatic device (117) and a dehumidifier mounted at least on a formation air inlet between the bottom of the stretching device and the top of the formation system.

Abstract: This device comprises a drum having a lateral surface through which fluid can pass, and two flexible belts (2) which pass over the lateral surface of the drum (1) at a distance from one another, each of them on an idle guide roller (3) of its own. Each roller (3) is mounted so as to pivot about a vertical axis (7).

Abstract: The invention concerns an installation for producing non-woven textile webs comprising a conveyor on one side of which the non-woven textile web passes between an injector and a vacuum chamber driven in an oscillating motion. The resulting web bears no mark.

Abstract: This brake booster comprises an enclosure (40), a diaphragm (42) dividing the enclosure into a front chamber (46) connected to a source of vacuum and a rear chamber (48), a piston (44) that can move axially in the enclosure and on which the diaphragm is mounted, a plunger (50) mounted so that it can move axially in the piston between a forward unstable braking position and a retreated stable position of rest, and a valve (54) intended to collaborate with seats (56, 58) on the piston and on the plunger. The or each seat (56) on the piston (44) is formed on the edge of a passage (60, 62) allowing the said chambers (46, 48) to communicate.
