  • a feed element is in a guide rail recessed and can be determined along the guide rails along previously Conveyor paths for the material webs are guided.
  • a lever is at one end connected to the web feed element and has a snap lock at its other end, to accommodate a paper take-up adapter that has the leading end a web of material that is on a roll in a roll changer of the rotary printing press is stored.
  • the guide link is attached along the guide rails driven and driven wheels, which are evenly spaced from each other are recorded along the conveyor rails.
  • the guide element has one Length, which is dimensioned somewhat larger than the distance from adjacent guide rollers.
  • a rotary printing press such as a roll changer, web feed unit, Printing units, web catching device, dryer and chill roll section each have hooking devices provide for threading a web of material, in normal operation
  • Unused mobile part of the web retraction device moved into a parking position can be in which the operation of the rotary printing press is not impaired and on the other hand, a quick movement of the mobile part of the web feeding device to the Point at which the material web is re-threaded into the components of the rotary printing press has become necessary can take place.
  • the web retraction element consists of a handset and each at the hanging stations included suspension segments.
  • the handset can be in the active state
  • Web feeder can be moved to a parking position while at the hanging stations the hanging segments that work with the handset are stationary can be maintained so that they are immediately available if necessary.
  • the holding devices can be used, for example, as magnets be formed or designed as a suction strips to which a vacuum can be applied be transverse to the direction of the web over the suspension stations on the components such as reel changers, printing units, web guards, dryers and chill roll sections of rotation.
  • Suction strips acted on as magnets or as negative pressure can be the hanging stations also as gluing stations or as hook-shaped holding means train for the material web sections.
  • the suspension stations are below the path of the material web through the Components of the rotation added.
  • the hanging stations point in the transverse direction cutting gaps extending to the material web, through which the material web each passing through cutting devices are included. So new straight cut ones can be made Generate the beginning of the web of the new web to be threaded, which is simple Way with the web feed segment that is suspended from the suspension station can be connected.
  • the handset of the hanging element is with stop faces provided because the handset is designed as a flat, flexible, easily deformable flat component is. By providing stop surfaces on the flat-shaped handset Web feed device, the risk of injury to the printer is largely excluded.
  • a material web 5 the one or is printed on both sides within printing units 23 of a rotary printing press, starts from a reel changer 22, one or more downstream of it Printing units before they pass a web catcher 18.
  • the web catching device 18 is accommodated on the front of a dryer 24 which has a chill roll section 25 is subordinate, which comprises a number of cooling rollers over which the freshly printed, material web passing through the dryer rotates before this one or two-sided printed, runs onto the web guide rollers 27 of a superstructure 26.
  • FIG. 2 shows a suspension station 4 in a schematic view out, recorded on a side wall of a printing press component 22, 23, 18 or 24 can be.
  • the suspension station 4 on the outlet side of the material web 5 from the listed components 22, 23, 18 and 24 of a rotary printing press.
  • a hanging segment 6 is added to, for example, four buttons 16 lying next to one another.
  • the hanging segment has an essentially triangular cross section, the tapering to a suspension opening 13 at the front of the suspension segment 6 approaches.
  • FIG 3 is a top view of a hanging station 4 at one Component 18, 22, 23 or 24 of the rotary printing machine reproduced.
  • buttons 16, of the in the illustration according to FIG. 3 four lying at the same distance next to each other below of the gap 10 are included, have a flat, relatively large head.
  • the hanging opening 13 and of the hanging head 12 on the handset 3 are also other design variants of a connection of components 13 and 12 conceivable, for example Velcro fasteners, adhesive tape connections or similar.
  • the hanging opening 13 with bulge is on one reinforced suspension strap 14 added.
  • the hanging tab 14 is on the Front of the hanging segment 6 in the area of the tip of the triangular hanging segment 6 attached, either woven with this, glued or on another Way attached.
  • the openings 20 in the handset give it extreme flexibility, significantly reducing its tendency to buckle and allow to drive the feed element consisting of handset 3 and To reduce suspension segment 6 drive power to be provided. Furthermore, the easy deformability of the handset 3 in its guide 2, the friction between the guide 2 and handset 3 significantly reduced. From the detailed drawing 6.1 of the Fig. 6 shows that the handset 3 in the form of a thin metal profile with an extending in the axial direction - for example as a pull rope - trained Web conveyor element is connected.
  • the hook button 12 will be as shown in Fig. 6.1 surrounded by the bumpers 21, so that the risk of injury to the printer is considerably reduced by the flat metal profile of the handset 3.
  • the handset 3 can also be made of a plastic be, which has an extreme flexibility, on the one hand, the friction in the guide element in the guide, and on the other hand, that during the threading path extreme deflections and the associated deformation of the handset enduring.
  • the hanging tab 14 is on the tip of the substantially triangular shaped suspension segment 6 is added is.
  • the hanging opening 13 can be seen, which is similar to an elongated hole is provided with a bulge and one on the tip of the hanging segment 6 has slit-shaped opening to be extended. This will be after entry the hooking head during the hooking process into the handset 3 from the shaft of the hooking head 12 penetrates and forms a connection between tensile forces Handset 3 and suspension segment 6, which make up the suspension element.
  • FIG. 7 goes from the detail according to FIG. 7.1 to FIG an opening 13, which is formed in the hanging tab 14, out more.
  • the hanging tab 14 can on suspension segment 6, which in turn consist of plastic can consist of a metallic reinforcement, so that the wear resistance of the Edges of one opening 13 are given permanently and are not replaced prematurely must become.
  • the hanging tab 14 can either be made with the material of the hanging segment 6 glued, welded, screwed, riveted or otherwise mechanically or be materially and positively connected to the tip of the hanging segment 6.
  • the configuration of the is essentially triangular trained suspension segment 6 out.
  • the Hanging segment 6 is not an isosceles triangle, but a right-angled triangle, the longer catheter of which is parallel to the direction of the web the material web 5 is oriented.
  • an adhesive tape can be used against the heat generated in the dryer 24 of the rotary printing press Resistance, so that the adhesive bond between the hanging segment 6 and the newly formed material web start during the passage of the Dryer 24 of a rotary printing press remains guaranteed.
