strives is the entry of the strip end between Claim: to prevent the rollers. . The object of the invention is to eme paper inlet Paper flow device for paper machines to create a device for a roughening device, with two parallel cylinder rollers of a rolling device which facilitate the introduction of the paper strip between the rolling device, one of which, as an empty spool, facilitates the rolling of the roughening device
for the roll of paper to be wound up and the This task is solved in that the jacket both have a pressure point through which the groove of the empty reel on the surface of the second Empty spool of paper to be wound through - roller or Pope cylinder roller on the runs, with the inlet of the paper web with an end associated with the strip with an over With the help of a narrow zone that gradually extends to the width of the circumference of the roller the web of growing strips is effected through holes in the jacket, and the web when it reaches its full width, the width of this zone being significantly smaller than is wound on the empty spool, thereby the length of the roller and one on the at the characterized in that the lateral surface of the 15 DrucksteUe of the cylinder rollers located part of the second suction device acting together with the empty reel (1) and perforated zone tend roller or Pope cylinder roller (2) to one on the pressure point of the cylinder rollers the end associated with the strip is intertwined with a subsequent part of the perforated zone over the circumference of the roller extending kende blower is provided. Through this Zone (5) with going through the jacket 20 is achieved on the one hand that the hitherto obstructive the holes, the width of this pressure effect when the paper strip enters the zone much smaller than the length of the roller and lifted after the paper strip has passed through and one on which can easily be detached from the Pope cylinder roller at the printing point Cylinder rollers (1,2) located part (6) of the per- can. forierte zone (5) acting suction device 25 It is a device for winding a and one on the pressure point of the cylinder fiber wadding on the winding mandrel of a winding machine rollers (1,2) subsequent part (7) of the per- known, in which the winding mandrel is a hollow roller foriated zone (5) acting blowing device is formed, the interior of which is provided via holes in the mandrel, is. jacket is connected to the outer circumference, so that 30 when a negative pressure is applied to the inside of the roller, the fiber wadding passes through to the winding mandrel "- is sucked in when the fiber wadding is between the Winding mandrel and with these cooperating counter-rotating pressure rollers runs through. The invention relates to a paper loading device for paper machines with two para- matic drawings on one execution sheet Cylinder rollers of a retractor, explained in more detail by game. which one as an empty reel for the F i g to be wound up. 1 shows a paper entry according to the invention Paper roll is used and both a DrucksteUe running device in a roll-up device form through which the paper machine to be wound onto the empty reel 40, with bed and other to be wound up Paper passes through, with the infeed rolling device belonging construction parts weggeder Paper web with the help of a narrow, gradually let are; to the width of the web growing strip F i g. 2 shows the retractor according to FIG. 1 is effected and the web on reaching full in a partial plan view and partially in section.
Width is wound onto the empty spool. 45 The roll-up device includes two cylinder When starting a paper machine or z. B., rolls 1 and 2, of which at least one or if for some reason the paper web is driven in the so-called Pope cylinder 2. the The running machine tears off what happens in practice. Roller 1 normally works as an empty spool for the occurs proportionally frequently, the procedure is that the paper to be wound up. When on the paper machine a narrower strip is removed from the paper web- 50 for one reason or another a disturbance, e.g. is separated, which occurs with the help of rope devices tearing off the paper web, is to the one leads and through the machine, like the end of the pressure stage between rollers 1 and 2 z. B. in Swiss Patent 422 503 be the paper strip 4 brought up and between the is written, make the paper web strip passed through rollers 1 and 2, after which you Trapping between a conveyor belt and a 55 begins, the paper strip on the other machine conveyor rope is taken to make the paper web end wider until it is fully operational introduce a dryer section. - Does it correspond broadly to the machine and then you get the lungs, the paper web strip is guided around the roller 1 through the on-paper web. - To Rolling device of the paper machine through to the invention is at one end of the roller 2 a gradually let it run up to the full 60 paper inlet device. This exists Increase the width of the paper web, then from a perforated zone 5, for the formation of which the with the normal production of the machine, one end of the roller 2 from the normal construction can drive. If the strip of paper has been modified between the two by adding the combined end and Rolling of the roll-up device of the paper machine bearing piece 3 at a greater depth than usual in the is passed through, result in practice 65 roller has been attached. Within this zone great difficulty in that the rotation of the is below the pressure point between the Rollers of the roll-up device in front of the printing station, rollers 1 and 2, a suction device, e.g. a these rollers cause a pressure zone, the well-known suction box 6, which is on the surface
