Definitions
- the invention relates to a method and a device for drawing in a web according to the preamble of claims 1 or 3.
- US 4063 505 A discloses a device for fastening a material web to a feed belt, a tip of the material web being inserted into a slot running perpendicularly through the feed belt and perpendicular to the transport direction.
- G 92 15 764 U1 describes a pull-in device in which a rope attached to the pull-in tip is pushed perpendicularly to the transport direction into the openings of the carriers, the cable being held against slipping out against the transport direction by a head piece of the cable on the carrier.
- DE 198 37361 A1 discloses a device for pulling in a printing material web, a free end of the feed tip being threaded through an opening of a driver connected to the pulling means and connected to a loop by means of a Velcro fastener.
- US 30 85 346 discloses a pull-in device for pulling in a web, a side edge of the web being clampable to a pull-in tip.
- the pull-in tip can in turn be hung on a belt of a pull-in means driven by air flow by means of hooks pointing in the opposite direction of transport.
- the invention has for its object to provide a method and an apparatus for pulling a web.
- the object is achieved by the features of claims 1 or 3.
- connection between the pulling-in means and the pulling-in tip simultaneously has a path limitation or stops against linear relative movements in and transversely to the transport direction.
- a sequence of two defined movements is required, the one movement representing a movement that does not occur in the pull-in process with a component perpendicular to the transport plane, a rotary movement, or at least a movement in which the connection is not loaded in the operating state.
- the first movement is to be carried out, at least immediately in front of the recess, as a movement with a preferred direction and in the region of the recess as a largely guided movement. This means that the connection is insensitive to unintentional loosening due to fluctuations in web tension or the speed at which it is drawn in.
- Figure 1 is a plan view of the device for pulling a substrate web in the non-connected state.
- FIG. 2 shows a top view according to FIG. 1 in the closed state (operating state);
- FIG. 3 shows a plan view of a second exemplary embodiment of the device for pulling in a printing material web
- FIG. 4 shows a side view according to FIG. 3.
- the feeding of webs is carried out in a known manner by means of feed means 01, such as, for. B. by a chain 01, a band 01 or a rope.
- the feed means 01 is generally arranged to the side of the paper web to be drawn in and is conveyed through the printing machine, for example in a rail or via rollers along the path provided for the paper web.
- a start 02 of the paper web is connected to recesses 03 on the feed means 01 itself, or on a driver 04 connected to the feed means 01.
- the beginning 02 of the paper web is designed as a drawing-in tip 02, which is connected to the paper web and can be connected to the recess 03 in a form-fitting manner with its free end with respect to a transport direction T.
- the pull-in tip 02 can be a film connected to the paper, a reinforced end of the paper itself, a one-part or multi-part reinforcement or extension, the non-positive, positive or material connected to the paper.
- the pull-in tip 02 is largely tear-resistant, at least in the area of the connection with the pull-in means 01 or the driver 04, for example as a metal or plastic strip.
- the pull-in tip 02 is flat and flexible with a small thickness and runs in a transport plane.
- the transport plane is understood to mean that plane which spans in the transport direction T at the level of the driver 04 or the recess by a transport direction T and the imaginary position of the paper in its width.
- the retractable tip 02 has at its free end a thickening 06 which interacts with the recess 03 as a lock 03 and key 06, the key 06 being able to be inserted in a preferred direction different from the transport direction T, and being released in almost all directions except for the Preferred direction is prevented.
- the key 06 is designed as a thickening 06 in the plane of the retracting tip 02 in the form of a barb 06 or anchor.
- the thickening 06 is preferably carried out with a steep flank 07 acting as a stop 07 from a width b02 of the retracting tip 02 to a width b06 of the barb 06.
- the barb 06 with its stop 07 interacts positively with the slot-shaped recess 03 in the pull-in means 01, in the present example the band 01, in the transport direction T.
- the longer section 08 of the recess 03 designed as a kinking slot 03 runs almost in the transport direction T and has at its end opposite the transport direction T a section 09 inclined to the section 08 by an angle ⁇ .
- the section 08 has a length I08 which corresponds at least to the width b06, while the shorter section 09 advantageously has a length I09 which is smaller than the width b06 of the barb 06 but larger than the width b02 of the pull-in tip 02 in the area of the connection.
- At least one of the two parts either the band 01 having the slot 03 or the driver 04 having the slot 03 or the end of the pull-in tip 02 provided with the barb 06 are made of a reversibly deformable, resilient material.
- the limit of travel between belt 01 or driver 04 and feed tip 02 with respect to a direction different from the transport level is brought about by stop 07.
- the retracting tip 02 may additionally have a second, for example mirror image, thickening offset in the direction of force F, which further restricts the path limitation of the retracting tip 02 through the recess 03.
- the path limitation with regard to the movements in the transport plane is caused by the stop 07 of the thickening 06, which penetrates the recess 03.
- the side surfaces of the pull-in tip 02 interact with the inner edge of the recess 03 as a stop in the transport plane.
- the drawing-in tip 02 has a thickening 11 protruding from one of its two surfaces.
- the thickening 11 designed as a head 11 is connected to the pull-in tip 02 via a web 12 (FIG. 4).
- the head 11 In its longest dimension, the head 11 has a maximum length 111 which is greater than a maximum width b11. Head 11 and / or web 12 can be rotatable about an axis perpendicular to the surface of the retractable tip 02 or rigidly connected to it.
- head 11 and web 12 cooperate with recess 03 arranged in band 01 or driver 04.
- the recess 03 has a length or a clear width 103 which corresponds at least to the maximum length 111 of the head 11, and a width b03 which is greater than or equal to the maximum width b11 but less than the maximum length 111 of the head 11.
- the recess 03 forms the negative for the shape of the head 11 in plan view, the recess 03 having a slight dimensional allowance.
- the web 12 has a maximum diameter d12 which is smaller than the width b03 of the recess 03 and a height h12 which corresponds to at least one thickness of the band 01 or the driver 04 in the region of the recess 03.
- the recess 03 (FIG. 3), with its longer extension, the length I03, runs largely in the transport direction T.
- the orientation of the recess 03 corresponds to the direction of force F prevailing under load.
- the head 11 is on the retracting tip 02 with its longitudinal extension transversely to the direction of transport T, in an advantageous embodiment aligned transversely to the direction of force F.
- the web 12 acts as a stop 12 in the transport plane, in particular in the transport direction T, with the edge of the recess 03.
- the head 11 protruding beyond the width b03 of the recess 03 and acting as a stop 13, the band 01 having the recess 03 or the driver 04 and the pull-in tip 02 connected to the head 11.
- the operation of the device for drawing in a printing material web is as follows: For the drawing in of a printing material web, the beginning thereof is provided with a drawing-in tip 02 which has a thickening 06; 11 has. The pull-in tip 02 is thickened 06; 11 in the hanging direction E (for example in FIG. 4) into the recess 03. The insertion takes place in one of the transport directions T and Direction of force F different direction.
- either the band 01 is rotated or deformed in the region of the recess 03 and the pull-in tip 02 with the thickening 06 is pushed into the longer section 08 of the recess 03, or the pull-in tip 02 is moved from a direction that is not in the transport plane, from below or above, in section 08.
- the pull-in tip 02 is moved against unintentional loosening by the stop 07 designed as flank 07 with the Edging of the section 09 of the recess 03 acts together.
- the connection is path-limited in terms of translation in all spatial directions. During operation, ie when the web is drawn in, there is a positive connection at stop 07 in transport direction T.
- the drawing-in tip 02 in the case of a thickening 11 rigidly connected to the drawing-in tip 02, the drawing-in tip 02 is twisted in the transport plane until the shape of the thickening 11 and the recess 03 interlock. If the thickening 11 and / or the web 12 is rotatably connected to the pull-in tip 02, only a twisting of the thickening 11 is required.
- the pull-in tip 02 or the thickening 11 is then rotated back into its “normal” position and the path-limited connection produced with respect to a translational movement is locked During operation, ie when the web is drawn in, there is a positive connection at the stop 12 in the transport direction T.
