Definitions
- the invention relates to a method for leading the beginning of a material web, in particular a paper web, from below to a rolling machine roller according to the preamble of claim 1 and a device for carrying out the method.
- the invention has for its object to provide a generic method that ensures safe vertical transport with the lowest possible compressed air supply. Another object is to provide a device for carrying out a method according to the invention.
- the first object is achieved with the measures of claim 1. It has been shown that a laminar flow which is essentially parallel to the web guiding element and adheres to its surface ensures safe transport of the beginning of the web.
- the second object is achieved with the features of claim 2.
- the subclaims contain preferred embodiments of a device according to claim 2: While the feature of claim 4 reduces the pressure required for transport, the liftable and lowerable web guide element according to claim 5 enables the web to be guided vertically between the knives of a longitudinal cutting device.
- Figure 1 schematically shows a device according to the invention in side view.
- the material web 1 - a paper web - is fed from below to a support roller 2 designed as a suction roller.
- a support roller 2 designed as a suction roller.
- Three guide rollers 3, 4, 5 are used to guide the paper web.
- Those arriving from a roll, not shown, approximately horizontally Web 1 is directed upwards by the guide roller 3, by the guide roller 4 into the vertical and by the guide roller 5 tangentially to the support roller 2.
- a longitudinal cutting device In the area of the vertical web guide between the guide rollers 4 and 5 there is a longitudinal cutting device with several pairs of circular knives arranged on a parallel to the support roller axis.
- the pairs of circular knives consisting of upper knife 6 and lower knife 7 serve to divide the web 1 into individual webs, the upper knives 6 being movable away from the lower knives 7 with a short stroke.
- a belt rocker 8 which can be pivoted onto the circumference of the guide roller 3 and a sheet 9 which adjoins it in an aligned manner steer the start of the web in the direction of the guide roller 4.
- a short distance apart from the guide roller 4 is a web guide element by means of a Pneumatic piston-cylinder unit 10 vertically movable, vertically extending over a part of the working width guide plate 11 which extends in the raised position from the guide roller 4 through the knives 6, 7 to the guide roller 5.
- the upper edge of the guide plate 11 is approximately at the height of the guide roller 4.
- the guide plate 11, which is arranged centrally, transverse to the direction of travel is approximately 500 mm wide in order to guide a web start of approximately 300-400 mm in width .
- 11 flat jet nozzles 12 are arranged at regular intervals from one another across the width of the guide plate and are fed from a compressed air supply, not shown.
- the approximately 50 mm wide flat jet nozzles 12 each have a plurality of discharge openings arranged next to one another with a diameter of approximately 1 mm, from which the compressed air emerges in a laminar flow.
- the basic structure of such flat jet nozzles is described in DE-PS 24 13 614.
- the flat jet nozzles 12 - in the present example there are three - parallel to the guide plate 11 and at a very short distance this arranged. It has been shown that the distance of the blow-out openings from the guide plate 11 must be less than 10 mm, preferably it is between 0.5 and 1 mm.
- a further nozzle 13 directs the start of the web in the tangential direction to the support roller 2.
- a belt rocker 14 which can be placed on the support roller 2 is arranged on this side .
- the ribbon arms 8, 14 are pivoted away from the respective rollers 3, 2, the guide plate 11 is in the lowest position outside the longitudinal cutting device 6, 7 so that the upper knife 6 rests on the lower knife 7 in the working position, and the nozzles 12, 13 are out of operation .
- the knives 6, 7 are first moved apart so that the guide plate 11 can then be moved into its upper position. In this position it extends along the entire route on which the new start of the path must be guided vertically.
- the ribbon arms 8, 14 are applied to the rollers 3, 12, and the nozzles 12, 13 are fed with compressed air.
- the width of the beginning of the web to be introduced is reduced to approx. 300 - 400 mm by tearing off at the edges.
- the length of the narrowed web start corresponds approximately to the conveyor path guide roller 3 - support roller 2, in the present example approximately 1500 mm.
- the new start of the web is then guided with conveyor belts, not shown, from the unwind to the guide roller 3, where it is deflected upwards by the adjacent rocker arm 8 via the sheet 9 into the area of the air flow of the flat jet nozzles 12.
- the flat jet nozzles 12 blow compressed air vertically upwards in a laminar flow along the surface of the guide plate 11. Due to the increased flow speed compared to the transport speed of the beginning of the path, a negative pressure is created between the guide plate 11 and the path 1, which leads the path 1 directly to the guide plate 11. In addition, due to the roughness of the paper surface, a force component acting vertically upward acting on the web is formed, which the web 1 transports upwards in cooperation with the feeding conveyor belts.
