  • the protection means can be mounted either on the first section or on the second section of the respective lath.
  • the roller comprises a basic roller body (as shown in FIG. 4 ), for example, a pipe, on which the laths 2 can be guided the protection means can be attached to the basic roller body.
  • the protection means 30 shown in FIG. 6 , FIG. 7 and FIG. 8 has a length which is larger than a maximum gap 33 between the first section 31 and the second section 32 of the respective lath, i.e., the length of the protection means 30 is larger than a maximum displacement in opposite directions of the first section 31 and the second section 32 of the respective lath during operation.
  • the protection means 30 comprises the following regions in the cross-section:
  • the perpendicular S runs through the center of the central region 30 a of the protection means. If the protection means 30 is arranged in the interior of the lath 2 the perpendicular S runs in radial direction through the center of the roller 1 and the center of the central region 30 a of the protection means 30 .
  • the protection means 30 shown in FIG. 9 a is symmetrical in its cross-section with respect to the perpendicular S. This cross-section guarantees that the protection means 30 bridges the gap 33 at any time when the apparatus is operating, and that an optimum, especially floating, arrangement of the protection means 30 in the interior of the lath 2 is provided.
  • the movement of the protection means 30 in the direction of the shaft A can be limited so that the protection means 30 does not slip through the lath 2 in the direction of the shaft A, thus no longer being able to bridge the gap 33 .
  • the protection means shown in FIG. 9 a , FIG. 9 b and FIG. 9 d comprises a lug 34 which is able to limit the protection means from moving in the direction of the shaft A.
  • the lug 34 extends over the width of a side region 30 b of the protection means 30 and is arranged outside of the center of the protection means in longitudinal direction. As shown in FIG. 8 the lug 34 is arranged inside the gap 33 .
  • the thickness or height of the lug 34 is in the range of the thickness of the lath 2 or slightly larger.
  • the width of the lug is similar to the minimum adjustable distance between the first section 31 and the second section 32 of the respective lath in the direction of the shaft A or smaller.
  • the lug 34 is arranged on the side of the protection means 30 facing the shaft A.
  • the lug 34 makes it possible that the movement of the protection means 30 in the direction of the shaft A is limited.
  • at least one lug can be arranged on the side facing away from the shaft, the side facing the material web. This lug can have a shape that corresponds to the shape of the gap.
  • the protection means 30 shown in FIG. 9 a - d comprises an external shape that corresponds to the contours of the support region 2 a , the side regions 2 b and the holding regions 2 c of the lath 2 .
  • This external shape of the protection means 30 it is possible to provide an optimum, especially floating, arrangement of the protection means 30 in the interior of the lath 2 .
  • the protection means bridges the gap 33 at any time when the apparatus is operating. At the same time there is merely minimum friction between the protection means 30 and the lath 2 .
  • the protection means 30 shown in FIGS. 6 to 9 consists of plastic material. This allows for a cost-effective production and, at the same time, noise generation and/or friction between the protection means and the lath is minimized.
  • the protection means 30 can also be produced from a different material that allows for a cost-effective production and that makes it possible to minimize noise generation and/or friction between the protection means and the lath.
  • the apparatus shown in FIG. 1 to FIG. 9 can be used especially in a facility for manufacturing or processing tires.
  • the material web consists of a rubber strip.
  • the speed of the material web (for example, in the range of 50 m/min) is typically lower than the speed of the material web in a facility for textile production (for example, in a range of 200 m/min). Since tires are manufactured in a dry environment the apparatus has to be adjusted accordingly. For example, it is possible to use ball bearing mounted reels in the apparatus. It is also possible to coat the laths appropriately, for example, with an anti-adhesive coating.
  • the apparatus can also be operated continuously, i.e., the control of the lateral displacement is performed when the roller is rotating. For example, this is the case when the apparatus is used in the facility of manufacturing tires along with the rewinding machine, the extruder and/or the calendar.
  • the apparatus can also have a discontinuous operation, i.e., for example, the lateral displacement is controlled with a stop interval function in which the roller is not rotating. For example, this is the case when the apparatus is used in the facility of manufacturing tires along with the cutting device. During the stop intervals the cutting device cuts the material web.
  • the apparatus for different applications, for example in a facility for producing or processing textile web, in which case the material web is a textile web.
  • the apparatus can also be used in a facility for producing or processing paper, in which case the material web is a paper web, or in a facility for producing or processing plastic foil, in which case the material web is a plastic web.
  • the apparatus can also comprise a detection means (not shown) for detecting the position of the material web.
  • the apparatus can also comprise a control system (not shown) for controlling the lateral displacement.
  • the control device is connected with the detection means and the actuator in such a way that the control device analyzes signals of the detection means and respectively activates the actuator in order to control the lateral displacement of the material web.
  • the detection means can comprise a web-edge sensor which detects the edge of the material web by means of a light beam and/or a camera. However, it is also possible to provide different types of detection means.
