The disclosed device for producing wire rope produces a filler-filled wire rope comparatively quickly. A tubular wire twisting machine (10) and a cage wire twisting machine (20) are disposed in tandem. The rotating shaft (14) of the tubular wire twisting machine (10) and the rotating shaft (21) of the cage wire twisting machine (20) are linked. Six lateral strands (3) are wound by the feed bobbin (12) of the tubular wire twisting machine (10), and six strands of filler material (4) are wound by the feed bobbin (27) of the cage wire twisting machine (20). The six lateral strands (3) and the six strands of filler material (4) are alternately twisted around the periphery of a core rope (2) supplied from the outside, producing a filler-filled wire rope (1).

In a pull-assembling unit for automatically assembling a pull onto a slider body of a slide fastener, a slider transporting means includes a slider-body-transportation plate member having rectangular notch portions spaced at intervals of plural assembling sections along a top end edge thereof, each for accommodating the slider body. The slider-body-transportation plate member is adapted to be actuated in the slider-transportation path so as to draw a rectangular trajectory in a vertical plane. An actuation upper limit position of a top end of the rectangular notch portion is set to be above a slider-body-placing surface of the slider-transportation path and an actuation lower limit position of the top end of the notch portion is set to be at a retreat position below the slider-body-placing surface. Therefore, the slider-pull-assembling unit has a simple structure and is capable of assembling a pull onto a slider body accurately and securely at a high speed.

The invention discloses a method for preparing a perovskite layer. The method comprises the following steps: providing a flexible substrate; providing a perovskite solution comprising an initial amount of a solvent and a perovskite precursor material and having a total solids concentration of between 30% and 70% by weight of its saturation concentration; depositing the perovskite solution on a substrate; removing a first portion of the solvent from the deposited perovskite solution and increasing the total solids concentration of the perovskite solution to at least 75% of its saturation concentration by a first drying step; and removing a second portion of the solvent from the deposited perovskite solution by a second drying step having a higher solvent evaporation rate, which results in saturation and conversion reactions in the deposited perovskite solution, resulting in perovskite crystal formation or perovskite mesophase formation, wherein the residence time of the first drying step is at least 5 times longer than the residence time of the second drying step. A continuous in-line method for high-speed production of photovoltaic devices and a perovskite solution for high-speed fabrication of uniform perovskite layers to enable low-cost production of efficient perovskite devices are also described.

Filamentous textile structures are produced from a quasi continuous planar nonwoven (1) by subjecting the nonwoven (1) to fluid-dynamic forces, namely in such a way that the nonwoven (1) is split up longitudinally into a plurality of parallel slivers (3) and the fiber structure of the nonwoven (1) is bonded in the slivers. For the treatment with fluid-dynamic forces, the nonwoven (1) is placed for example against a treatment template (10) which is structured in a strip-like manner by perforations (11) and elevations (12) and fine water, saturated steam or air jets (13) are directed against the nonwoven (1) and the template (10). The slivers produced during the treatment with the fluid-dynamic forces can be processed without any further treatment into a planar textile structures or they can be subjected to a further treatment prior to said processing in order to increase their strength. Said further treatment can preferably be performed without any application of additives (false twist, rubbing) or it is a further treatment which can be reversed after the production of the planar structure (treatment with glue). The slivers (3) have a relatively large volume and can therefore be weaved into covering fabrics with relatively low thread densities. They are suitable for example as weft yarns in fabrics for low-quality needs such as fabrics for disposable linens.
