  • Such devices for separating a paper web are for example from the US4711404 , from the WO86 / 00282 and from the EP708049 B1
  • a tear tape is passed from one side of the paper web through a guide channel to the other side thereof.
  • the guide channel is formed on its side facing the paper web with an opening.
  • the tear strip In known such guide channels, in which the tear strip is moved from one side of the paper web to the other side of the paper web, it must be ensured that the tear strip remains in the guide channel during movement to the other side of the paper web and not through the paper web facing opening beyond the guide channel.
  • the guide channel for the tear strip is formed on the web facing the paper web with two mutually facing strips, whereby the width of the opening is less than the width of the tear strip.
  • the tear strip consists of several side by side and interconnected paper cords.
  • the tear tape consists of a folded paper strip.
  • a tear tape which has a middle band part, which paper strip and the like. contains, project from which lateral band parts.
  • the middle band part has more than ten times the width of the lateral band parts or they have a very small width.
  • they are formed with a cross-section enlarging away from the side edges.
  • the lateral band parts are further formed with profilings, whereby they have a wave-shaped course, by which the cutting action of the tear strip is to be improved when separating a paper web.
  • the present invention is therefore based on the object to provide a tear strip, which ensures that it is not damaged when pulling out of the guide channel through the paper web facing opening of the guide channel to cause the separation of the paper tape.
  • the tear strip in cross section has a middle band part and two side band parts, wherein the middle Band part opposite the lateral band parts has at least 1.5 times the thickness and wherein its width is approximately equal to half the width of the tear strip or has a smaller width of at least 1/6 of the width of the tear strip.
  • the middle band part is formed with a plurality of juxtaposed paper cords or with a plurality of paper layers.
  • the tear strip can be formed by an at least single-ply paper tape, which is provided in its central region with a support of paper cords or at least one paper layer.
  • the tear strip is formed by an at least two-ply paper tape, which is provided in its central region with an insert made of paper cords or at least one paper layer.
  • the thickness of the pads or inserts in the middle band part from paper cords or from at least one paper layer decreases from the middle area to the lateral areas.
  • the paper cords or the at least one paper layer can be glued to the at least single-ply paper tape.
  • the middle band portion is formed with a substantially thicker paper tape which rests on a paper sheet at least one ply or is wrapped by a paper tape at least two-ply.
  • the middle band part can also have a width which is at least 1/5, 1/4 or 1/3 of the width of the tear band equal.
  • An installation for winding a paper web which is located at the end of a paper-making installation, has a first drum, on which the paper web arriving from the paper-making installation is wound up.
  • a further empty drum is provided, on which the paper web is then wound up as soon as the first drum has reached the desired winding diameter.
  • the paper web In order to be able to move from the first drum to the empty drum during the winding process, the paper web must be separated.
  • This purpose is served by a tear strip whose free end is conveyed from one side of the paper web through a guide channel located in a guide rail to the other side of the paper web.
  • the leading end of the tear tape is attached to the rotating empty drum by means of an adhesive coating thereon, whereby it is pulled out of the guide channel through an opening facing the paper web and spirally wound on the empty drum.
  • the paper web is separated helically and the front tear edge of the paper web is brought to the empty drum for conditioning, whereby the paper web is wound on the empty drum.
  • the full drum is removed and in its place the other drum on which the paper web is wound up, arranged.
  • the paper-making equipment can be fed at a speed of e.g. 25 m / sec fed paper web are continuously wound on drums. Once a drum has reached the intended winding diameter, the paper web is separated, the transition of the winding takes place on an empty further drum and the full drum is removed.
  • FIG.1 a tear strip 1 and a guide rail 2 are shown with a guide channel 20.
  • the guide rail 2 is located in a system for changing the drums, on which a paper web is wound up.
  • the tear tape 1 is shifted through the guide channel 20 from one side of a paper web to the other side.
  • the tear tape 1 has a middle band part 11, which is relatively stiff, and two lateral band parts 12, which are relatively elastic.
  • the guide channel 20 has a central region 21, the clear width of the width of the tear strip 1 is approximately equal.
  • the guide rail 2 On its side facing the paper web, the guide rail 2 is formed with an opening 22, which is located between two mutually facing strips 23, whereby the width of the paper web facing opening 22 is less than the width of the tear strip 1.
  • the guide rail 2 is further formed with a groove 24 which serves to receive a befindliches at the front end of the tear strip 1 adhesive element, by which the free end of the tear strip 1 is fixed to the rotating empty drum for the separation process of the paper web.
  • the tear strip 1 can be pulled out of the guide channel 20 for opening the paper web through the opening 22, without it being damaged thereby.
  • the tear strips 1 according to the FIG.2A and FIG.2B differ from the tear tape 1 according to FIG.2 in that there are only four or three paper cords 14 in its middle band part 11, as a result of which the middle band parts 11 have correspondingly smaller widths.
  • the middle hinge parts 11 have the required high tensile strength, whereas the respective two lateral hinge parts 12 have a high elasticity.
  • Tear tape 1 shown consists of a single-ply paper tape 15, on the middle band part 11, five juxtaposed paper cords 14 are located.
  • This in 3a illustrated tear strip 1 consists of a single-ply paper tape 15, in the middle band portion 11, a substantially thicker paper tape 16 is located, whose width is approximately equal to the width of five paper cords 14.
  • This in Figure 3B Tear tape 1 shown consists of a single-ply paper tape 15 which is formed in its middle band portion 11 with three stacked paper bands 17, the widths of which shrink from the paper tape 15 away.
  • FIG.4 illustrated tear strip 1 consists of a two-ply folded paper tape 13, in the middle band portion 11, a substantially thicker paper tape 16 is located, which is enclosed by the folded paper tape 13.
  • This in 4a shown tear strip 1 consists of a two-ply folded paper tape 13, in the middle band part 11, three stacked paper bands 17a are located, which are enclosed by the paper tape 13, wherein the middle paper tape has a slightly larger width than the other two paper bands.
  • This in 4B illustrated tear strip 1 consists of a two-ply folded paper tape 13, in the middle band part 11, a twice folded and thus three-ply paper tape 18 is located, which is enclosed by the paper tape 13.
  • Tear tape 1 shown consists of a single-layer paper tape 15, in the middle band part 11 there are seven paper cords 14a, which have from the center outwardly decreasing diameter.
  • This in 5a illustrated tear strip 1 consists of a two-ply paper tape 13, in the middle band portion 11 is a much stronger Paper tape 16a is located, the thickness of which is reduced from the center to the outside and which is enclosed by the paper tape 13.
  • This in 5 b Tear tape 1 shown consists of a two-ply, folded paper tape 13 which is formed in its middle band portion 11 with seven paper cords 14a, which have from the center outwardly decreasing diameter and which are enclosed by the paper tape 13.
  • All of these tear bands 1 have in cross-section a middle band part 11 and two lateral band parts 12, wherein the middle band part 11 at least 1.5 times the thickness, preferably 2 times the thickness and according to the embodiments 5 times the thickness of the lateral band parts 12 and the middle band portion 11 has approximately half the width of the entire tear strip.
  • the tear tape 1 can also be formed with a middle band part 11, which has 1/6, 1/5, 1/4 and 1/3 of the width of the entire tear strip 1.
  • the tear strips 1 Due to the reinforced middle strip parts 11, the tear strips 1 have the tear strength which is required for the separation of the paper web.
  • the lateral band parts 12 have a substantially smaller thickness, they fulfill the function that the tear band 1 does not pass out of the opening 22 through the opening 22 on its movement in the guide channel 20 to the other side of the paper web.
  • the lateral band parts 12 are so elastic that the tear strip 1, as soon as it is pulled out of the guide channel 20 through the paper web-facing opening 22 through it, not damaged and in particular is not separated.
  • FIG.6 the individual phases of the movement of the tear strip 1 from the located in the guide rail 2 guide channel 20 are also shown, from which it can be seen that the tear strip 1 by means of the lateral band portions 12 during its promotion to the other side of the paper web out in the central region 21 of the Guide channel 20 is held and that it due to the elasticity of the two side band portions 12 for the separation the paper web is pulled out through the opening 22 of the guide channel 20 without being damaged thereby. This also avoids that the guide channel 20 is clogged by separated paper parts.
