Definitions
- the invention relates to a drying chamber for drying a printed web, consisting of a housing with inlet and outlet openings for the web and at least one infrared radiator directed at the web and / or warm air blowing air nozzles blowing on the web, preferably drying chamber for flexographic printing printed webs on the bridge between the flexographic press and the unwinding and reeling devices is arranged.
- drying printed Sheets in drying chambers have the problem of being good and rapid drying is hindered by the fact that through an inlet slot in the web entering the drying chamber entrains air that adheres to the web forms an insulating layer that prevents good drying.
- the object of the invention is therefore a drying chamber of the type specified To create a way that eliminates an insulating layer of air covering the web so that they do not hinder and delay drying of the web can.
- Turbulence generators are arranged above the track.
- the web to be dried usually runs into the drying chamber with the printed side facing upwards, so that the turbulence generators arranged above the web co-operate with the web a turbulent air flow, which the entrained by the train isolating air layer or boundary layer by swirling and eliminated so that those consisting of blown air nozzles and / or IR radiators Drying facilities the web unhindered by an insulating layer of air can act.
- Turbulence generators are expediently arranged on both sides of the web.
- the turbulence generator can be made across the direction of travel of the web and parallel to this arranged inclined or curved sheets.
- the sloping metal sheets are advantageously at an acute angle the direction of travel of the web so that it envelops the web Peel air layers as it were.
- the web Sheets are arranged in the shape of a cylindrical shell. These are preferred arranged so that the concave sides of the sheets face each other.
- the curved sheets preferably have a wing-shaped profile.
- FIG. 1 shows an eight-color flexographic printing press 1 with eight printing units, whose pressure rollers are attached to a common impression cylinder are.
- a drying chamber 5 On the bridge 4 there is a drying chamber 5 surrounded by a housing, through which the printed web from the flexographic printing machine 1 to the reel-up running.
- the housing 6 of the drying chamber 5 has an inlet slot 7 and an outlet slot 8 for the printed web to be dried.
- In the housing 6 of the drying chamber 5 are preferably curved Web guide rollers 10 stored, over which the printed web 11 to be dried runs.
- Drying devices are on the printed side above the web 11 to be dried directed in the illustrated embodiment from a convector 12 and infrared radiators 13 exist.
- the convector 12 can be a Act blow nozzle arrangement that blows warm air onto the printed web 11.
- bowl-shaped sheets 14, 15 are arranged above and below the web, whose concave sides face each other.
- the cupped curved Sheets 14, 15 are arranged at a distance from the web 11 in such a way that their concave sides face each other, so that gap-shaped inlet and outlet slots are formed.
- the bowl-shaped sheets 14, 15 are arranged in mirror image to the pass plane of the web 11, so that due the air currents from the sheets exerting suction on each other cancel.
- FIG. 3 shows alternative configurations of the turbulence generators which can be used alone or in combination.
- Adjacent at the inlet and outlet areas are bowl-shaped sheets or bodies 18, 19 are provided, which are curved, the concave sides facing each other are.
- the sheets or bodies 18, 19 are mirror images of the flow plane of the arranged to dry web 11.
- Sheets 20, 21 In the middle area of the drying chamber are sloping or slightly curved Sheets 20, 21 arranged, their cutting edges leading in opposite directions the direction of travel of the web 11 are employed on both sides against this, so that they peel off the layers of air enveloping the web.
- the sheets 20, 21 are arranged in mirror image to the pass plane of the web 11.
