Definitions

  • the invention relates to a blow box according to the Preamble of claim 1.
  • the winding hardness plays a role when winding webs for subsequent processing. Especially at Paper webs, it is very important that the winding hardness a certain one over the entire roll diameter Has course. In general, the winding hardness of one certain initial value fall to a final value. The trash should be as possible from the first to the last layer be even. It is supposed to have a certain gradient have, i.e. not too strong and not too weak. The course of the winding hardness should under no circumstances Have jump points, e.g. a sudden drop.
  • a winding device which has a blow box, which by pivoting or Procedure is removable from its working position.
  • blow box has a very large volume as well as a correspondingly high weight. You have to be there imagine that he is the entire length of the Extends wrap bed that measure several meters can, and that its weight is many hundreds of kilograms. This requires an elaborate movement mechanism a corresponding drive. It also claims Moving or swiveling the blow box completely considerable space, which is often not available.
  • the invention has for its object a blow box according to the preamble of claim 1 to create the remains stationary if you have paper scraps after tearing off the Want to remove paper web. It is said to be a elaborate movement mechanism with associated drive be avoided in this case and also a lesser Space for the entire machine can be achieved.
  • FIG. 1 shows a blow box 1 of a winding device with two side walls 1.1 and 1.2, which in a preferred embodiment can be designed to be stationary.
  • the blow box 1 Above the blow box 1 are two support rollers 2, 3, together a changing bed to hold one over it form lying paper roll, arranged.
  • the paper roll arises by winding a paper web 5. How to sees, the paper web 5 is brought up from the bottom left and wraps around the support roller 2.
  • the paper roll can from a load or rider roll in a controllable manner be burdened in order to also increase the print run influence.
  • the blow box 1 has sealing elements 7, 8, one Sealing between the relevant walls of the blow box 1 and the respective support roller 2 or 3.
  • the Connecting wall 10 serves such waste paper to catch up.
  • the paper waste is on the connecting wall 10, so it can be much easier and faster through a remove the two end faces of the blow box 1 as if it were on the bottom of the blow box 1.
  • the Removing the paper waste can also be automated be, for example by means of a scratch or a revolving conveyor belt.
  • the connecting wall 10 has in the present case perform the following functions:
  • connecting wall 10 could also be a Blinds with which it is possible to assign the individual compressed air flows through the holes of the Pass through connecting wall 10 in its throughput to change arbitrarily.
  • FIG. 2 Another embodiment of the invention is shown in FIG. 2 shown. You can see the blow box 1 there as well the two seals 7, 8.
  • the blow box 1 according to FIG. 2 has an embodiment in addition to the connecting wall 10 stiffening ribs 11 on which the side wall 1.1 with the side wall 1.2 of the Connect the blow box.
  • To the air supply line 1.3 of the Blowing box are attached sheets 14 with which the Air supply line 1.3 is fixed in the blow box.
  • the connecting wall serves 10, which may be perforated in the illustrated Embodiment also for this, when the paper web is torn off to catch the paper scraps.
  • the connecting wall 10 is between the side walls 1.1 and 1.2 also arranged inclined so that the paper scraps independently in the blow box can slide.
  • blow box 1 in the embodiment 2 an embedded in the side wall 1.1 Opening 12 on.
  • a device for Arranged arranged, for example as shown a flap 13 which is pivotable on the main part of the blow box 1 is mounted - see swivel axis 13.1.
  • the inclined connecting wall 10, which in the lower section 1.4 of the side wall 1.1 is attached.
