A conveyor-band line of an apparatus for the dyeing of leather is composed of at least two knife belts arranged in succession. Since one knife belt is restricted only to the region of a spray device for dyeing the leather, the remaining knife belts remain free of dye residues. To remove the still damp dye residues on the knife belt guided through the spraying machine, a washing system is provided.

The in-situ milling of rail heads of rails 14 is effected by a device having at least one driven rotating milling head (2) with at least one milling cutter head drive (3) mounted on a bogie frame 16 which has guide shoes (4) which can be selectively raised and lowered and are arranged ahead of and behind the milling head (2) with of reference to the direction of travel. Lateral guide rollers (5) a...

A leather stacker is provided with a knife edge in the region of the delivery end, with the result that the distance during the transfer of the leather to the delivery table is reduced and therefore a crease-free transfer can be achieved. A photocell switches on a drive of a delivery table, so that, at the moment when the leather is transferred, the delivery table is moved at the rotational speed ...

A continuous-flow pressing and ironing machine for the ironing or embossing of leather has a feed conveyor band which is guided around an ironing cylinder and to which a smoothing conveyor band is assigned on the top side. The latter is guided round a knife edge in the region of a further ironing cylinder and forms a wedge-shaped gap relative to the transport part of the feed conveyor band. In thi...

Skiving machine for the skiving of hairless skins or leather, with transport rollers, with a belt knife arranged downstream of the latter in the transporting direction and with a conveyor band for transporting away the upper strand of leather. In order to ensure a crease-free removal of the hairless skins or leather from the belt knife, provision is made for the conveyor band to be guided in the i...

The safety guiding device for delimiting traffic areas, in particular roads and carriageways, comprises elongated concrete parts 9 which are put together or can be put together with abutting longitudinal ends to form a bordering barrier and have a protective surface layer 5 made of plastic or synthetic-resin material, forming a lost formwork for the concrete parts. To increase durability and safet...

The invention relates to a process for the manufacture of multi-layered wear-resistant CVD- or PVD-coatings applied to hardmetal parts containing WC-Co or WC-Ni, where at least one of the layers is a metal-boronitride layer. According to the invention, the boron concentration in the metal-boronitride layer is maintained below the critical level above which in addition a homogeneous boronitride mix...

The invention relates to a device for treating, especially cleaning, inner surfaces of objects connected as cathode by ion bombardment from a gas discharge which has been ignited and maintained between an anode and the cathode. According to the invention, at least one essentially rod-shaped anode is provided which is surrounded at least partially by the inner surfaces which are to be treated, espe...

The invention relates to a rod-shaped magnetron sputtering cathode arrangement having an internal cooled permanent magnet system and a support tube for the target. The invention provides for at least one heat contact layer 38 to be located between the support tube 36 and the target comprising one or more ring(s) 37, 37', 37" pushed onto, particularly in a replaceable fashion, the support tube 36. ...

Used foundry sands, in particular clay-bound used sands, are wet- regenerated by preliminary scouring of the used sand mixed with water, treatment of the used sand/water mixture in several successive attrition stages of a friction washing plant, drawing off and scouring the mixture at each attrition stage, feeding the scoured mixture into the next attrition stage in each case and finally draining ...
