Definitions
- the invention relates to a device according to the preamble of claim 1. Such a device has become known from DE 38 20 846.
- the invention has for its object to provide a device that ensures a positive transport of the web upwards, with little equipment and with little adjustment effort of the individual parameters responsible for the aerodynamics of the blown air.
- This roller is generally vacuumable.
- the entire guidance of the blown air is extremely simple.
- the blow nozzles are usually round bores or slots, in any case not flat jet nozzles, which achieve a laminar air flow.
- the blowing effect of the nozzles is extremely effective and requires little air resistance. Due to the design according to the invention, the paper web floats on an air cushion, which is located between the paper web and guide plates. Sticking of the paper web to the guide plate is definitely avoided.
- the drawing shows a device for guiding the beginning of a paper web 1 to the roller 2 of a rolling machine.
- the guide plates 10 and 11 are inclined to the vertical.
- the plate 11 is arranged steeper than the plate 10.
- the plate 12 is finally arranged vertically, also the plate 13.
- the plate 14 is curved and thus leads to a deflection of the web 1.
- the plate 15 is finally inclined and runs in essentially tangential to the lateral surface of the roller 2.
- plates 10 'and 11' can be arranged in order to convey the web upwards in another way.
- the first two plates do not have to be inclined, but can run vertically.
- blowing nozzle 21 is a turbulence-generating nozzle.
- this nozzle is located at the transition between the last inclined plate and the first vertical plate. If all the guide plates are only arranged vertically, then this blowing element with the turbulence-generating blowing nozzles should be arranged approximately in the central region of the conveyor line, at least not too far from the beginning of the entire conveyor line.
- the web is also guided by a number of guide rollers 30, 31, 33.
- Two circular knives are provided, (not shown), one of which serves as a counter knife. These two circular knives can be used to make a longitudinal cut through the paper web.
- An additional blowing member 25 serves to fix the paper web to the lateral surface of the roller 2.
- the blow nozzles are best made from ordinary holes. These are best at a mutual distance of 1 to 20 cm, preferably 10 cm.
- the holes have a diameter of 1 to 5 mm, ideally 1.5 mm.
- a cable pull device 40 with guide rollers 41, 42 serves to raise and lower the insertion device.
