Embodiment Construction

[0022] FIG. 1 is a simplified schematic representation of the delivery channel 4 provided in the delivery drum 7 for supplying fluid to the nozzles 5 , 5 ′ formed thereon. A rotary valve 9 is arranged opposite the end face of the delivery drum 7 , which is connected via a central bore 20 to a fluid medium delivery line 23 from a pressure pump 22 . The rotary diverter valve 9 is arranged non-rotatably, relative to which the conveyor roller 7 is known to be rotatable when it operates like the conveyor roller 7 or the roller knife 8 . In the rotary diverter valve 9 , connecting channels 21 , 21 ′ are formed from the central bore 20 , the outlets of which are located on the side close to the end face of the conveying drum 7 . When the opening of the delivery channel 4 coincides with the opposite opening of the connecting channel 21 in the direction of rotation, the medium is always under pressure in order to allow fluid flow within a limited angular range. At other angular positi...

Abstract

The invention relates to a method and a device for guiding and supporting a comparatively thin sheet or metal strip (1) during transport over a conveying device (10) such as a rolling table and / or during, before or after a cutting process taking place. The invention is characterized in that the sheet or metal strip (1) at least on its lower side (1') is subjected to high-energy beams (2, 2') of a liquid or gaseous medium emitted by jet nozzles (5, 5') and thus supported and guided by pulse energy.

Description

technical field [0001] The present invention relates to devices and methods for supporting and guiding a metal strip or sheet during conveyance by a conveying device such as a roller table and / or during, before or after cutting through a shear, wherein the sheet or strip is at least from Its underside is impinged by a high-energy jet of a liquid or gaseous medium, which is conveyed under pressure via conveying channels in the conveying roller and / or roller knife to the outer circumference nozzles on the surface, and the medium flows out of these nozzles in the roller support area or as densely as possible next to the roller knife cutters and obliquely or approximately perpendicularly relative to the sheet or metal strip and flows out of said nozzles to the sheet or strip material. Background technique [0002] In rolling technology practice, it has proven to be difficult to reliably feed the sheet or strip to the shears, for example by means of conveying devices such as rol...
