Definitions
- the present invention relates to a device for drawing a material web into a rotary printing press according to the preamble of claim 1.
- Web feeders typically require bonding a web of material to a guide means, hereinafter generally referred to as a "queue".
- a guide means hereinafter generally referred to as a "queue”.
- Such connecting elements are generally formed as a triangle.
- the lateral stresses caused by the tension of the web across its width act mainly on the apex of the triangle where it is connected to the guide means.
- By these lateral loads there is a risk that the material web is released from the connecting element, that wrinkles form or that the web breaks.
- connection of the triangle with the guide device is difficult insofar as the triangle must be aligned with respect to the transport path of the material web to avoid offset feed and / or web displacements. It is known to connect the triangles at their apex with the guide device. As a result, the triangle is rotatable to a certain extent, which makes it difficult to fasten the web to the triangle. Since the triangle is not attached along the transport path of the web, alignment of the triangle with the web is difficult to achieve. In addition, it is not easy to position the edge of the triangle to coincide with the edge of the web.
- GB 2 315 062 A discloses a web-puller having a draw-in triangle and a mounting portion for attaching the triangle to a pulling device.
- the draw-in triangle has a first side, at the leading tip of the mounting portion is attached. The trailing end of the first side of the triangle has no contact with the attachment portion.
- At the attachment portion is again in the running position, a loop which can be hooked into a corresponding counterpart of the pulling device, so that the draw-in triangle is acted upon by a tensile force acting on the tip.
- the draw-in triangle has a hypotenuse to which parallel and orthogonally reinforcing fibers extend.
- DE-U 92 15 764 already discloses a device for drawing in a material web by means of a draw-in tip, which consists of a first and a second element and which is connected at a leading portion with a pull rope. While the second element has an elasticity for avoiding impact or jerky loads on the material web to be pulled in, the element can consist, for example, of a tear-resistant textile fabric, which preferably has a rubber coating. The pull-in is acted upon by the pulling action of the pull rope with a force which engages only in the leading tip portion in the area.
- the Invention may be provided a number of attachment points at which the draw-in triangle is attached to the guide means along the entire length of one side of the draw-in triangle.
- the attachment points in this way firstly facilitate the orientation of the draw-in triangle and secondly allow easy attachment and detachment of the draw-in triangle.
- the draw-in triangle is made of a reinforced material similar to a fiberglass mat.
- the mat consists of a fabric with tissue fibers arranged at right angles. Since the material may be rough, it may also have a coating which avoids damage to the web upon contact. Conceivable materials for the mat contain z. As aramid or carbon fibers.
- the coating may, for. B. of a polymer, such as. As rubber or neoprene exist.
- a part of the fibers is arranged running in a first fiber direction parallel to the hypotenuse of the triangle, and a further part of the fibers, which serves primarily the fixation of the first fibers in the direction parallel to the hypotenuse of the triangle, but otherwise almost no contribution to Receiving the web forces caused by the web is arranged to extend substantially perpendicular to the first fibers.
- Such an arrangement of the fibers creates a plurality of squares defined by the parallel fiber strands.
- the strands serve to reinforce the structure of the triangle between the points of attachment of the triangle to the guide means and the area where the web is attached to the triangle. In this way, a better displacement of the load on the guide element and avoiding the displacement of the web causing rotation of the draw-in triangle is achieved.
- a stiffening attachment may be provided on the underside of the draw-in triangle in close proximity to the web, acting as a reinforcement along the width of the web and preventing the web from slipping and wrinkling.
- the attachment may preferably be made flexible in the transport direction of the web so that it can be bent around rollers during the web feed.
- a preferred material for the stiffening insert is for example a polymer;
- the stiffening attachment can also be made of metal, provided that it leaves no traces on contact with the rollers. It would be conceivable z.
- the attachment is preferably secured to the draw-in triangle such that it is an integral part thereof.
- the attachment may have a gap through which the web can be threaded to secure it to the draw-in triangle.
- the web may be pulled through the nip and then secured to itself with preferably double sided tape.
- the attachment may preferably have a rounded edge to avoid damage to the web at the nip.
- a terminal strip arrangement may be arranged, by means of which the web is fastened to the draw-in triangle.
- the terminal block assembly may include terminal strips of rounded cross-section so as to prevent tearing of the web.
- the draw-in triangle can be fastened to the guide device via lugs arranged in a row and preferably parallel to the guide device on the triangle-arranged lugs.
- the eyelets can be hung in arranged on the guide device hooks that hold the eyelets during the web feed.
- the hooks can be designed such that a slipping of the eyelets from the hook during the web feed is not possible.
- the hooks may also have an opening and closing function by which they hold the eyelets. The effect is similar to that of a zipper.
- connection of the hooks with the eyelets for attaching the triangle to the guide device via an external device automatically, for example, in that the hooks are widened by means of a part of the device apart, then the eyelets on the hook be placed, and then bent back in such a way that they pinch the eyelets.
- the external activation device can be arranged, for example, for fastening the draw-in triangle in the region of the roll stand and furthermore for removing the draw-in triangle on the folding apparatus.
- a zipper can also be provided in a further advantageous embodiment of the invention.
- This has the advantage that it - with a correspondingly small distance between the teeth of the zipper - serves as an additional reinforcement.
- a zipper basically has a certain flexibility and is easy to open and close. It may also be provided a device for automatically attaching and detaching the draw-in triangle, the z. B. automatically closes in the area of the reel changer and automatically reopens in the area of the folder.
- a suspension device may be provided for fastening the draw-in triangle to the guide device, which may comprise, for example, a first section for guiding the hooks and a second guide section for hooking the eyelets into the hooks.
- the guide device may comprise, for example, a first section for guiding the hooks and a second guide section for hooking the eyelets into the hooks.
- the first guide portion may preferably be formed a gap through which the hooks can run.
- the suspension device can be used to efficiently fasten the draw-in triangle to the guide device can be used without the hoses must be manually hung individually in the associated hooks. Due to the suspension device, only the first eyelet must be hung manually to initiate the attachment process.
- This suspension device is used to automatically mount a plurality of eyelets in the associated hooks and so to attach the triangle along one side of the guide device. With the help of the device it is also possible to remove the feeder triangle. It may also cooperate with automatic unwinding devices for retracting the draw-in triangle or winders for removal and storage of the draw-in triangle.
- the hooks are guided by means of a first guide section of a hooking device and the lugs are hooked into the hooks by means of a second guide section of the hooking device.
