摘要： An innovative plant (10) for the production with the “spun bonding” technology or similar of a web (V) of non-woven fabric, comprising: a melting station (11) suitable for receiving and melting a polymeric base material (MR), an extrusion bar or head (12) with a plurality of extrusion or drawing nozzles (12a) adapted to receive from the melting station (11) the polymeric material (MR) in the molten state to produce a plurality or bundle of continuous filaments (FF); a conveyor belt (13) adapted to advance along a direction of advancement (A) and to receive from the above the continuous filaments (F), produced by the extrusion nozzles (12a), so as to form a web (V) of non-woven fabric; and consolidation means (14) designed to consolidate the non-woven web (V) formed on the conveyor belt (13); wherein the plant (10) is characterized by a special structure (20) comprising a base platform (21), rotatable (f, f′, f″) around a respective vertical rotation axis (X), and wherein the melting station (11), suitable for receiving and melting the base polymeric material (MR), and the extrusion bar (12), suitable for receiving from the melting station (11) the polymeric material (MR) in the molten state, are totally built and solidly supported by this rotatable base platform (21) (f, f, f), so as to be rigidly connected to each other without the interposition of any rotating joint. Advantageously, the plant (10) allows to vary, without interrupting its operation, the width (L, L′, L″) of the non-woven web (V) produced by the same plant, by rotating (f, f′, f″) and adjusting the base platform (21) around the respective vertical rotation axis (X), so as to vary the inclination (a) of the extrusion bar (12) with respect to the direction of advancement (A) the conveyor belt (13).

摘要： An injection nozzle for electrospinning including a first nozzle body and a second nozzle body detachably coupled with each other and nozzle members inserted in the first and second nozzle bodies and an electrospinning device using the nozzle. The electrospinning device basically performs air electrospinning wherein a source liquid for fiber is injected together with air while the source liquid for fiber is discharged through the nozzle members, and pure electrospinning without air injection can be efficiently carried out by separating the second nozzle body in such a manner that the lower ends of the nozzle members are exposed for a predetermined length or more. Therefore, according to the present invention, pure electrospinning, air electrospinning or hot air electrospinning may be selectively carried out.

摘要： A strand caster, in particular for plastic strand casting systems, is provided, which in a known fashion consists of a nozzle plate and a caster. The nozzle plate and the caster include abutment surfaces facing each other, and the nozzle plate is mountable to the caster by corresponding mounting elements. The surface structure of at least one abutment surface of the nozzle plate or respectively the caster is adapted such that, due to the fastened state caused during operation, the one abutment surface accommodates to the opposing other abutment surface under tension so that an uniform surface pressing between the nozzle plate and the caster is achievable.

摘要： A spin pack for spinning synthetic fibers from two or more liquid polymer streams includes a supply for at least two polymer streams to the spin pack; a spinneret having extrusion orifices; and flow distribution plate sets. The flow distribution plate sets include at least one patterned plate having edges which define a substantially regular two-dimensional geometric shape, a substantially planar upstream surface, a substantially planar downstream surface and at least one flow distribution pattern stenciled therein by cutting through. For each patterned plate, at least one boundary plate stacked sealingly adjacent thereto and having edges which define a substantially regular geometric shape, a substantially planar upstream surface and a substantially planar downstream surface. The boundary plate has cut-through holes connecting the upstream surface with the downstream surface to form at least one flow-through channel to allow fluid flow through the patterned plate but otherwise is substantially solid.
