Embodiment Construction

[0024] The device for levitatingly guiding the continuous material or the web 3 has a complete guiding conveying surface 2 which itself extends along a conveying path in the conveying direction 11 of the continuous material or the web 3 . A plurality of nozzles 1 are provided at predetermined intervals in the guide conveyance surface 2 .

[0025] An existing nozzle 1 is produced by means of a forming tool by straight or curved punching (transverse to the intended blowing direction) and deep drawing (sag of the material relative to the plane of the guiding conveying surface 2), as a result, in a A straight or curved first (sharp) edge 17 and at least one second (sharp) edge 18 are generated in the region of the first blow opening and a second blow 6 , 7 . Similarly, a third (sharp) edge 19 for a third blow opening is simultaneously formed for each nozzle 1 with the shaping tool. The blowing outlets 6, 7, 8 stretch into a flow channel 5 that is connected with a pneumatic system...

Abstract

The invention relates to a device for suspended guidance of web or sheet material in a processing machine. The invention aims at providing a device such as the one previously described, which enables uniform pressure build-up for suspended guidance of web or sheet material along a guide surface and noticeably reduces the risk of blotting. This is achieved by providing a flow channel (5) having a guide surface (2) with a plurality of nozzles (1). Each nozzle (1) has a back and a front area. The back area has a depression (14) relative to the guide surface (2), said depression ending in an edge (17). Each nozzle (1) has a first blow hole (6) beneath the edge (17) and at least an adjacent second blow hole (7). The blow holes (6, 7) are adjoined by a guide surface (4) that continues onto the guide surface (2).

Description

technical field [0001] The invention relates to a device for suspending and guiding continuous or sheet material in a processing plant, which device is particularly suitable for non-contact guiding and conveying of sheet material in printing presses. Background technique [0002] DE-OS 1907083 describes a known device of the above-mentioned type, which has a bellows comprising a guiding conveying surface and a plurality of blowing openings arranged in a decentralized manner, each having an inclined guide surface sunken into the bellows. However, these nozzles have a tongue there, with an angle between the radial edges of the guide surfaces of 120°-180°. As a result, an air jet with a wide fan area, ie a non-directional air jet, is produced in accordance with the flat effect. All blowing outlets are also arranged in the same direction. As a result, a quasi-tensioning effect can only be produced in one direction, which is disadvantageous precisely for thin webs, which are th...
