Example, an adhesive tape dispenser 14, the structure of which is explained in more detail with reference to FIG. 7, and / or preferably a reflective foil dispenser 16 and a cutting device with a held on an articulated arm 18, circular cutting blade 17, which by means of an actuating cylinder 19 from the illustrated retracted position is lowered into a cutting position in which it intersects the cutting edge 51 of the work table 06.
  • a second actuating cylinder is provided with a direction of action perpendicular to the plane of FIG. 6 in order to press the cutting blade 17 in its lowered position against the cutting edge 51 of the work table 06.
  • a clamping finger 21 which is shown in Fig. 1 from the rear portion 13 of the work table 06 in the vicinity of the cutting edge 51 upwardly projecting, pivoted down to a lateral edge of the tail of the paper web to this against the work table 06th to press and fix so.
  • the cutting and tape dispensing device 11 moves on the rails 12 at a first, high speed.
  • a sensor 22 arranged adjacent to the cutting blade 17, for example an optical sensor or a reed contact detects when it, coming from the front in the perspective of FIG. 1, crosses the front edge 23 of the work table 06 and then triggers the actuation of the actuating cylinder 19 out, so that the cutting blade 17 is extended.
  • the second actuating cylinder is activated to the cutting blade 17 to the cutting edge 51st to press.
  • two sensors 24; 26, z. B. two web edge sensors 24; 26 here Reflexfotozellen, provided for detecting the edges of the paper web during the movement of the cutting and tape dispensing device 11.
  • the sensor 24 detects the right edge of the paper web and causes a reduction in the speed of movement of the paper web Cutting and tape dispensing device 11, so that the sensor 26 crosses the edge in question at a lower speed.
  • the sensor 26 When the sensor 26 detects this right edge, it activates another sensor 27 which is aligned with a scale attached to one of the rails 12 that carries position coding, such as a Gray code. By reading the relevant code at the time the second sensor 26 detects the right web edge, the sensor 27 is able to accurately measure the position of the right web edge.
  • position coding such as a Gray code
  • the cutting and tape dispensing device 11 is again accelerated to the high first speed, and the cutting knife 17 rapidly cuts through the paper web until the sensor 24 detects the crossing of the left web edge. Again, the speed of the cutting and tape dispensing device 11 is reduced to accurately measure the position of the left web edge with the aid of the second web edge-oriented sensor 26 and the scale-oriented sensor 27.
  • the cutting and tape dispensing device 11 continues until the left end position of the guide has been reached and thus the left edge of the worktable 06 has passed; now the cutting blade 17 is raised again and the movement of the cutting and tape dispensing device 11 is stopped.
  • a path of the adhesive tape 29 and the shroud 30 extends from the supply roll 28 initially via a plurality of pulleys 31 to a braking device 32 and from there in turn via pulleys 31 to a vertically movable pressure roller 33.
  • the braking device 32 comprises a stationary and one with the aid of an actuating cylinder movable brake shoes 35, between which adhesive and shroud 29; 30 are passed.
  • a belt tensioner is arranged in the form of a on a pivot arm 52 by means of an actuating cylinder 53 against the shroud 30 acted upon roller 54.
  • the pressure roller 33 is lowered by adjusting cylinder (not shown) to press them along the previously cut by the cutting blade 17 on the edge held on the work table 06 paper web. Since the adhesive tape 29 adheres more strongly to the paper web than to the shroud 30, shroud 30 and adhesive tape 29 separate at this point, and the path of the shroud 30 continues to a collecting device 34, for. B. a take-up reel 34 on which the shroud 30 collects.
  • Adhesive tape 29 and shroud 30 are conveyed by means of a drive roller 37 which, between the pressure roller 33 and the take-up reel 34, is looped around only by the shroud 30.
  • the drive roller 37 is rotatably driven by a motor 36 (see FIG. 8) which rotates only when the pressure roller 33 is lowered against a paper web and whose rotational speed is exactly proportional to Movement speed of the cutting and adhesive tape dispensing device 11 is controlled so that the peripheral speed of the drive roller 37 coincides with the movement speed. This can be z. B. be carried out with a speed feedback. Thus, a tensile stress of the paper web during gluing, which could lead to undesirable slippage, avoided.
  • the take-up reel 34 is slippable, for example, via a belt, coupled to the motor 36, so that the shroud 30 is always wound at the speed determined by the pressure roller 33.
  • clamping tools 38, z. B. a roller 38, z. B. a tension roller 38 and a Hilfsandrückrolle 39 is provided which are movable by means of adjusting cylinders 41 between a raised position and a lowered position in which they press against the paper web or the work table 06.
  • Fig. 8 shows a view of the tape dispenser 14 from below.
  • the above-described components 28, 31, 32, 33, 34, 36, 49 and 41 are held.
  • this base 42 moves exactly parallel to the cutting edge, with the various rolls partially over that part of the web that remains on the paper web roll 01, and partially over the cut Part.
  • the motor 36 is above the cut part.
  • the course of the cutting edge 51 is indicated as a dot-dash line.
  • the axis of the tension roller 38 is not aligned exactly perpendicular to the base plate 42 and to the direction of movement of the cutting and adhesive dispensing device 11, but it deviates slightly from the vertical so that they the axis of the auxiliary pressing roller 39 on the paper web roll 01 facing side of the base plate 42 crosses.
  • This inclination of the tension roller 38 is achieved that when the Cutting and adhesive tape dispensing device 11 from the left to the right relative to the perspective of Figs. 6 and 7, ie with the tension roller 38 ahead, moved across the paper web, the tension roller 38 on this paper web exerts a clamping force in the direction of the cutting edge 51 out.
  • the web edge is always taut and can not beat waves when the tape dispenser 14 moves across it.
  • a cutting tool 43, z. B. a cutting blade 43 is pivotally supported on a pivot arm 44 by a control cylinder 46. It serves to sever the adhesive tape 29 in each case after the completion of an adhesive tape dispensing operation. In order to exclude that the cutting blade 43 thereby damage the paper web, the cutting blade 43 is suspended so that it moves at a small angle ⁇ to the direction of movement B of the cutting and adhesive tape dispensing device 11.
  • the tape dispensing process proceeds as follows. After the cutting and tape dispensing device 11 moves from right to left on the work table 06 and thereby cut off the paper web, it is now moved back, the sensor 27, the location of the cutting and tape dispensing device 11, z. B. based on the scale, continuously monitored. (Instead of the scale, a rotary encoder coupled to the drive is also possible.) For example, only the pulses of a stepping motor can be detected).
  • Detected 27 calculated position at which the pressure roller 33 is located exactly over the left edge of the paper web, the pressure roller 33, tensioning roller 38 and auxiliary pressure roller 39 are lowered and the motor 36 is put into operation, so that adhesive tape 29 at the speed of the cutting and Tape dispensing device 11 is unwound and pressed onto the edge of the paper web, wherein the lying between the tensioning roller 38 and the auxiliary pressing roller 39 portion of the web edge is tightened as described above.
  • the pressure roller 33 is raised again. Simultaneously with the lifting of the pressure roller 33, the braking device 32 begins to clamp shroud 30 and tape 29 so as to tighten the now freely extending between the right edge of the paper web and the raised pressure roller 33 piece of adhesive tape. Subsequently, the cutting blade 43 moves down to sever the tape 29 exactly at the level of the web edge. Only then does it come to a firm clamping on the braking device 32, and the promotion of the adhesive tape 29 by the motor 36 is stopped.
  • the roller 54 of the belt tensioner is moved against the adhesive tape 29 in order to tension the cover tape 30 so that the beginning of the adhesive tape 29 comes to rest for the next bonding process at the location on the periphery of the pressure roller 33, which touches the paper web to be bonded.
  • the adjusting cylinder 46; 53 which drive the movement of the cutting blade 43 as well as the braking device 32, are provided with a throttle, which slows the movement of both, in the case of the cutting blade 43, to prevent them in spite of the small angle in which they relate moved onto the paper web, it hangs on this and it breaks through, in the case of the braking device 32 to synchronize the braking operation with the cutting of the adhesive tape 29 so that the braking device 32 already tightens the tape 29 when the cutting blade 43 hits it, however, it does not completely stop, which, as the entire cutting and tape dispensing device 11 continues to move, would result in the tearing of the adhesive tape 29 at an uncontrollable location.
  • Both throttles are adjustable in order, if necessary, to be able to adapt the speeds of the braking device 32 and the cutting blade 43 to each other.
  • the cutting and adhesive tape dispensing device 11 moves further at the high first speed into its basic position shown in FIG.
  • the arms 08 which carry the rubber rollers 09 and brush roller 49, pivoted back into the position of FIG. 2, in which they rest on the circumference of the paper web roll 01.
  • the rollers 47 of the lifting device 04 are set in motion to rotate the paper web roll 01 in the counterclockwise direction, so that the paper web end is pulled down from the work table 06 and back to the paper web roll 01, while - either in or against the direction of the paper web end on the Worktable 06 rotating brush roller 49 presses the paper web against the body of the paper web roll 01 and so finally presses a projecting beyond the cut edge of the paper out portion of the adhesive tape 29 against the body of the paper web roll 01.
  • the free end of the paper web is fixed on the supply roll body until it is withdrawn for use.
  • the lifting table 04 is lowered again, so that the paper web roll 01 again comes to rest on the carriage 03, the carriage 03 is continued on the rail 02, and the arms 08 return to their in Fig. 1st shown starting position back.
  • the device 05 is now ready to prepare a second supply roll in the manner described above.

Parts of this adhesive tape dispensing device 14 which correspond to those of the adhesive tape dispensing device 14 of FIG. 7 are designated by the same reference numerals and will not be described again.
  • the drive roller 37 is omitted in the embodiment of FIG. 9. Instead, the motor 36 is slippage coupled via a belt to the take-up reel 34, so that the shroud 30 is always wound with an adjustable lead to the speed of the pressure roller 33. This contributes to the fact that z. B. loops, which may arise due to the alternating curvatures between shroud 30 and tape 29 as they pass through the adhesive dispenser 14, are pulled taut, so that they can not interfere with the cutting of the adhesive tape 29.
  • FIG. 10 shows, again in a view analogous to FIG. 7, a third embodiment of an adhesive tape dispensing device 14.
