Paper roll wiokel machine with several tfiokelwellen.

Be ttasohinen are known for making paper rolls « where they automatically finish a Bolle this ejected and without interrupting the material feed the winding of a new hell is started

With this paper roll machine you will find it tfickelwellen in two transport stars «which on sitting on a common axis and intermittent Rotational movement of the rocker shafts one after the other «Leading stations. For peeling off the ffickel and pulling it up of the cardboard sleeves, the Wiokel shafts are led out of the Tranaportstern and placed in a suitable position Transport stars again

The subject of the present invention is a further development of the paper roll winder machine described, on the basis of which the winding speed and thus the performance of the machine can be increased considerably with less construction effort.

This is done according to the invention in that the two tfickelkern- ^ Sransportsterne have different diameters and the nfiokelwellen on their one cortex in radial Slitting of the tfickelkern crane port star with a larger diameter and on its other volume in the slide of the im tfickelkern-Transportetera with smaller Durohmesser radial

This can be done in an advantageous manner that on Wickelkera-'franaportstern with larger diameter parallel Movable bag sliders guided to the slits are arranged, the movement of which is controlled by a washer so it is controllable that the end of a winding shaft guided in the slots through during the release of its other end the sliding block through the ätützschieher against a fixed one Guideway is pressed. The ätützsohieber two parallel to each other, at a certain distance from each other, firmly connected supports have, and the fixed guide track can on the Jeite of the support slide opposite Jeite of the winding shaft between attack the two supports · -in this way, a three-point bearing is produced at this end of the .ülokelwello, the a possible tilting of the tflckelwelle during the release of your one land prevents «
